LiveSuit problems
I have formatted my Chinese tablet PC from 'LiveSuit' software.
Now my tablet PC is showing blank screen.
Please tell me how can I re-install the operating system on my tablet?
Old operating system is ICS.

You need to find a ROM image that has been built for your specific tablet. If you want to reinstall the OS you had before, you need to obtain the same ROM image the manufacturer used. You might be able to get this from the manufacturer. (But if you want this, why would you wipe the ROM?)
Alternatively, you could install a custom-rom. These can be found on various web fora such as XDA Developers by searching for the model of your tablet. You may be able to get one for a different Android version, but only if someone has built an image for the model you have.
Once you have the ROM image, simply use LiveSuit again to flash it to the device.

Why i can install any windows version on my pc but i cannot install any android version on my phone?
I guess it's a silly question but i don't get it xD.
I've read it's about controllers, but they can be downloaded from manufacturers, right?

Load MP3 files on my Nexus
I want to listen to mp3 files of a lecture while viewing pdf files (containing the lecture notes).
How do I load the MP3 files onto the Nexus?
(The MP3 files currently reside on my hard drive.)

You can connect your device via the USB cable and then drag and drop the files from your PC to your device. You can also transfer the files via a syncing app like Google Drive or Dropbox etc. Use the music player of choice to keep playing the audio files while you use your office viewer / to read the PDF file.

You have several options at hand. You can:

Use an external cloud storage such as Dropbox. Install the app for your computer and for Android then add files on your computer and watch as they sync on your phone.
Use Google Play Music. Download the Music Manager software and have the software scan your computer for music files. Install the Play Music app on your phone and the music will be available.
Use a USB cable to directly transfer the files from your computer to your phone.

Galaxy S4 filtering incoming connections
I am trying to run an ftp server app on my galaxy s4 (tmobile) and it starts ok, binds to the wifi address and port 8021, but then I can't connect to it. I tried pinging my internal ip address as well and it's not responding. I also tried running nmap on it and it says All 1000 scanned ports on 192.168.1.102 are filtered. I haven't been able to find any settings or anything - any idea what could be blocking the ports? I have checked the IP both via a ip info sort of app, as well as through my router's connected devices page. Any ideas?
Update: I just tried a different FTP app just to make sure and same thing.
Update: Here's my nmap output:
$ nmap 192.168.1.102 -Pn -p 8021

I am trying to connect to the phone from my windows box via filezilla and running the nmap from my raspberry pi, again on the same wifi network.
I also checked the router's connected devices and the IP address there matches what the phone shows.
Thanks!

Running FTP servers on default port like 21 didn't seem to work for me.. Try running the ftp service on something like 2121..

Running FTP servers on any port below 1024 will require root -- so if the device is not rooted, the service is not offering anything on that port (it simply can't). I would also check if the router somehow firewalls your connections.

Ah, good point, but unfortunately that's not it - I am using a 8821

@Izzy my router doesn't filter anything

OK, so one candidate filtered out. May I suggest you to edit your question and include those details (port used, filter checked, port range checked ("all 1000": from port..to port? Including the port you've configured for your FTP server?)). I further assume 192.168.1.12 being the IP of your SGS4, and nmap was used from within the same network (e.g. a machine with IP 192.168.1.* connected to the same router)? Clear facts help finding good answers :)

This turned out to be a problem with my router - earlier today I also noticed that I couldn't connect to my printer either - it seems like the router had gotten in a weird AP isolation mode or something like that somehow - I rebooted it and I can connect to the S4 as expected now.

how long can the battery in my new mobile stay idle till first use
I bought a Samsung Galaxy 6 months ago. Have not used it yet nor have charged the battery atleast once. I am worried about the battery. Can i keep it idle two more months.

You might want to check How frequently is it okay to let the battery discharge fully or as low as possible? and A: Although I was told to charge my Android device before first use, it was already charged. Ha… for this, which include corresponding hints. Some basic stuff here, though:
Wikipedia holds a detailed article on Lithium-ion batteries. For your question, the answer is mentioned there as follows:

Li+ batteries have a self-discharge rate of approximately 5–10% per month, compared to over 30% per month in common nickel metal hydride batteries, approximately 1.25% per month for Low Self-Discharge NiMH batteries and 10% per month in nickel-cadmium batteries. They last longer if not deeply discharged (depleted) before recharging. The smaller the depth of discharge, the longer the battery will last.
Batteries may last longer if not stored fully discharged. As the battery self-discharges over time, its voltage gradually reduces. When depleted below the low-voltage threshold of the protection circuit (2.4 to 2.9 V/cell, depending on chemistry) it will be disabled and cannot be further discharged further until recharged. It is recommended to store batteries at 40% charge level.

(emphasis mine)
From that you can deduce: If the manufacturer behaved responsibly (which we may assume), the battery was charged at about 40% when leaving the factory. Assuming it took at least a month to get to you (it was at store as well, so it should have taken that long or longer), and consider the fact you bought it 6 month ago, the battery wasn't charged for at least 7 months. Self-discharge rate, according to the article, is 5-10% per month -- so your battery is pretty empty now, and most likely already about to enter the "dangerous level" of deep-discharge.
Conclusion: You should at least check it twice a year (once every 6 month) and make sure to charge it up to ~40..50% when not using it.

How to trace/track my stolen Samsung Galaxy Ace 2
Today was a bad day for me as I'm having a lot of problems. The latest and important event was I lost my phone. It was registered with my name and email and has information on it about me etc. The sim card is inside (if the robber didn't thrash it). The phone has gps but it's turned off. I hope I can find it.
If you have any question just ask me, maybe about the story how it began?
Is there any software/tools to track it, or find it manually maybe?

You will need to submit a request to Police Station to track your android device through its IMEI number. As soon as the mobile is switched on and it gets Signal from telecom company, its location will be detected.
Or alternatively, If you had any tracking app, installed on your device, then you may contact app developer for help to track your device.

is this things "ppl report to police n police track with IMEI" thing u said..rare or it was the often useed solution?

well! I have came accross this situation once. I lost my android device with No SIM CARD INSERTED in it. somebody got it and was using it . So this stuff helped me to get my device back... It is very oftenly used method but i will recommend you to search for someone who can track your device personally with IMEI because Police is so slow...

And that tracking is what the solutions in my answer provide, amongst other things. So if your device was stolen, I recommend going both ways in parallel -- but start with the solutions I mentioned as soon as possible: if the thief disables your account on the device (e.g. wipes it), they won't work anymore.

The thief would have been disabled all his account by now...

i think..naahhh..because i still can open the google play with my google account and the GP still can trace my phone with my google account..but idk if the sim was changed..it said Celcom and gt-18160(my sim celcom..but when i called always voice mail)..

I was saying that the Thief may probably have removed/changed your account from you device. -_-

can u use IMEI?

No! you need some specific machines to do so. That is why i am refering Police Station. They can track it easily if it is being used with any sim.

k ill try..
other way???

No! There is no other way to track the device.

I strongly recommend you take a look at the lost-phone tag-wiki, which contains a lot of first-aid hints. As you write your SIM is still in the device, there's hope it's also still connected to your Google account and has a network connection -- so hurry up trying solutions like Plan B or Android Lost, which you can then push to your device via Google Play's website. Find more details in the linked tag-wiki, plus on the apps' page at Google Play.

and if the sim was thrashed???cause i called always voice mail..yes it was my account in the phone..

As long as your account is still alive and connected on the device, mentioned solutions should work. They can't work obviously without a network connection. The SIM, on the other side, should be of not much interest to them (as long as a network connection is available, and your account still active on the device).

about the plan b..i ady installed it from pc..bu then it said step 2. Plan B will start automatically and send your phone’s location to your Gmail address.
3. To locate again after 10 minutes, borrow a friend’s phone and text the word “locate” to your lost phone...until now..i've done the text message..i sent locate(as there are no email from plan B in my gmail)..about 2 hours ady..

and the android lost..and still cant control...it said:
Waiting for phone to be registered.
Register your phone by starting the application on your phone. If you have forgot your phone at home you may remotely start the app by sending an SMS with the text 'androidlost register' to your phone. Wait a little while. Please be patient. Relogin to this page to see if it has been registered..also 2 hours ady..

Sorry, I never used any of those solutions myself -- so I cannot say for sure; but to me that looks very much like there's no SIM card inserted anymore (so it cannot receive your SMS), and the device connected via WiFi, if at all (maybe not at all anymore, if there's no response). If I were the thief (beware!), the first thing to do would be switching off the device. And before switching it on again, remove the SIM so it doesn't connect to any network. Then, if I'm after the phone, wipe it, re-flash it. If I'm after your data, it's a different thing -- but for sure no network.

remote registration doesn't work on Android Lost - https://groups.google.com/forum/#!msg/androidlost/Vo5_F0wF_do/0CUPZ5o2nuYJ

How do I change my email address on Play Store as the one I have is no longer in use
The email address I have on Play Store is no longer verified and I wish to change to my current provider as I do not seem to be able to download apps

What do you mean "change my provider"? Its not going to change the content you can get from the play store. Just get yourself a new email address and add that into settings>account>…youll have the choice of what email address to use when you enter the play store.………are you sure that is the reason why you can't download? Did you try clearing the data/cache? Search through Stack Exchange for "non-working play store" ( I'm not at my computer now, otherwise I'd provide a link for you).

Go to settings->accounts->add account->and add another Google account with the new email. Then go into the play store and there will be your email with a drop down arrow. Tap it and select the new email.

What Google page should I be on when I click "Settings>Account"...? Every (or nearly every) Google service has a "Settings" gear and probably a lot of them have some settings for "account". I tried this by going to play.google.com, then I clicked: "gear"->"settings". I don't see any place to add a new email address (or edit existing).

Will my device get locked again after update?
I've bought samsung captivate glide I-927 from eBay. It is locked with at&t by default, so seller unlocked device for me and it is working fine. It comes with Gingerbread 2.3.5 and I found that ICS update for this device available from Samsung kies (pc suite). Now the question is Will my device get locked again after update from GB to ICS???
Thanks in advance...

No, software updates do not mess around with carrier info like that. Your phone should still be set to work with AT&T after the latest update is applied. If updating the device meant reactivating the phone, many people would be unhappy because of activation fees.

I'm in India and seller have unlocked this for global GSM carriers. So is it still work with Indian GSM carrier after update? I'm asking you because you mention at&t in your answer.

I'm actually unsure if it will revert back in your case. I believe that will depend on what image you use to update your device.

Setting up automatic reboot?
This may sound a bit lazy, but does anybody know of an app or a method that can automatically reboot one's phone? I sometimes forget to reboot it daily (I like keeping my OS fresh).

If your device is rooted, Tasker can do that (there's a free trial available at their website for you to check first). While you don't need to boot your device daily (I don't boot it more often than once a month usually, if at all), I also thought about a weekly reboot on a device having problems otherwise (my old Wildfire started behaving oddly with calls after about 10 days uptime).
So here we go, assuming a weekly reboot at Monday morning 3am for a fresh week:
Condition:

Day → Day-of-week: pick "Monday"
Time: Set both, From and To time to 3am

Task:

Reboot

I have to include a warning here from the Tasker UserGuide on Reboot:

Unfortunately, this is not a 'clean' shutdown. Neither Android nor running applications are informed that the device is rebooting, so be prepared for possible data corruption.
On the other hand, every other app that allows reboot does it the same way.

So this warning does not apply to Tasker alone, but obviously to all other solutions as well.

How to view all calls logs for a contact?
I am using Galaxy S 3 phone with Android 4.1.2
Is there a way to view all call logs for a specific contact?

View a contact (either from the Contacts app or by clicking them in the Phone app). Then press the menu hard-key, and History is the first item on the list.
Note: my Samsung Galaxy S III has been upgraded to Android 4.3, so I've no idea if the method is the same in Android 4.1.2, or if this is something Samsung has added since then. If anyone is still on 4.1.2, please check and comment!

Well, my 2c is that this doesn't work on my Android 4.2.2 device.

I have Google voice, in addition to my cell carrier's assigned phone number, so this may not be true for everyone, but you can use Google Takeout to download all your data for any Google service you use. Just go to www.google.com/settings/takeout, and pick the services you want to review. Google will pack them all up in an archive which you can then download and search. A little painful if you do this on a regular basis, but a life-saver if you need to check something that is no longer on your phone, but is kept in your online history.

You are unable to filter the call log for a specific contact in 4.1.2 You would have to find an application on the Play store to do that for you.

I posted a similar question to this elsewhere and was pointed to this thread, which did not really answer my question either. Posting my question, I thought that I may get some answers here, as it is, after many hours searching and trying various apps out, I have found a few apps that provide solutions myself, the best two of which I will list below.
I was looking for an app to show "call" & "sms" "history"/"logs" for an individual contact, so using these search terms I found many, the best stand alone one I found is called "My Log" from "Intangible Solutions" which is able to search and list all calls and sms for any given number or multiple numbers in a very clear and easy to read format. The drawbacks is that it is heavily add supported and takes a little while to specify all the contact's numbers, as you have to select them one at a time, having said this, the results are brilliant.
The other I found via an associated app call "Call log+" which I tried and initially dismissed as it only gave me call log similar to the one found in the standard "Phone" dialler, however I later went back to it's associated app "Contacts+", which includes "Call log+", "Messages+" and "Dialler+", and then also installed "Merge+", "Emoji for Conacts+" and the "Contacts+ Widget" to get the full collection, which can replace the standard "Phone", "Contacts" and "Messaging" functions with much better versions, that do far more. The "Contacts+", which includes "Call Log+" does everything I wanted, in that I can instantly see a call log for any contact. The fact that "Contacts+" does a whole lot more beyond this, is also fantastic, but it does exactly what I wanted, so job done.
I hope this may help others looking for the same missing (removed) feature, which because of how I use my phone, I would find hard to live without.

SMS backup +, copies your call logs to your GMail account which then groups them by contact

How to toggle hangouts
I'm trying to find an easy way to toggle hangouts on/off, but it seems it runs as a mandatory service, and the only solution I found is to disable it in settings/app, which is not very handy, and I think it reverts it to an outdated version each time.
Is there an easier/quicker way ?

Is your device rooted?

No, I am afraid it is not.

If it were, Titanium Backup could have been an option: it enables you to put a widget on your homescreen to toggle between "freeze" and "unfreeze + start"...

Can I upgrade My Xperia Arc S To Jelly Bean after the rooting
I am planning to root my Xperia Arc S and want to know whether will I be able to upgrade it to Android Jelly Bean.

After rooting you can install it using Jellybean custom ROM. Check this below link ;   http://www.android.gs/update-xperia-arc-paranoid-jelly-bean-4-1-1/

Sony stopped with ICS, it didnt release Jellybean for Arc S. If you are rooted and installed CWM recovery you can install Jellybean Custom rom. There are plenty of rom available here. Just read the instruction before installing the roms. There are roms which are only for unlocked bootloader.

Do i need to root the phone to flash custom ROM ? I have already unlocked the bootloader.. is there a difference between them?

Mostly no, but you need to have CWM recovery installed. Just follow the installation instruction given in the rom page.

Most of the times, if not all, rooting is necessary to upgrade to a newer version, especially if it is unofficial(custom ROM). You also have much more power on your phone, but it has the drawback that the guarantee will be voided.
In your case, I have found that it is easier to upgrade. You just need to install pc-companion and after you connect the device on it, it will download the latest update(Jelly Bean).
If I were you, I would download the update first and then I would root my phone.
http://www.knowyourmobile.com/sony-ericsson/sony-xperia/17465/how-update-your-sony-xperia-arc-s-android-40

Hi I have tried to do that but it says that the phone is up to date and doesnt give an option to upgrade to 4.1 or 4.2.I have got ICS installed but is there anyway i can upgrade before i could start with the root.

Default contact for a number
Is there a way to set a default contact for a specific number, which happens to be bound to multiple contacts?
I.e. for some reason Alpha and Bravo share a telephone number. Currently if I try to send a message to Alpha, it "appears" as I'm sending it to Bravo (the number is the same). Can I make it "appear" as I'm sending it to Alpha, instead?
NOTE: in case someone didn't read carefully, this is the opposite of selecting a default number for a contact (it's selecting a default contact for a number).
I'm using cm7 and cm10.1.2 on two different phones, and they both display this quirk.

Have you tried the combinations: Default on one contact-not default on other and default on both?

@py_script yes, it's already default in the desired contact, and not default in the other :/

Is there a similar way to do this for an email address?  My son starting using email before he was old enough for a gmail account.  So my wife gave him wife-son@gmail.com.  Now gmail from my wife (wife@gmail.com) comes up as "Son's name" not "Wife's name", which is annoying.

@Gdalya Any chance filtering and applying tags (labels) would work for you?  http://webapps.stackexchange.com/questions/2593/how-can-i-filter-incoming-email-based-on-plus-addressing-in-gmail

@Lohoris The filtering comment was for the e-mail comment above it (by Gdalya).

@A.M. oh, I see, I'll just delete my comment then

If I understand what you're after, this should do the trick:

Add a P (pause) at the end of the phone number for whichever contact(s) you do not want to be the default.  I imagine a W would also work, but I can only vouch for a P.
Ensure the "default" contact (if that's what you mean) has the normal number.

In your scenario, just change Bravo's number from, say, 1-800-555-1234 to 1-800-555-1234P.
I just tested this approach and both numbers dial.  The first thing I tried was adding an extra digit, but that did not work.

While the idea is great, for some weird reason it worked on 4.1 but not on 2.3 :(

However it apparently was just a cache problem: clearing contacts data did the trick, thanks!

My way did not work on 2.3?  That's a strange pattern.  I'm running 2.2, so...2.2 yes, 2.3 no, 4.1 yes??  Maybe it depends on the UI.  Ah well.  I'm glad it's all working for you now.

It stopped working right now, after upgrading to cm 10.1.2 (Android 4.2.2). Now I think that the P was really irrelevant, and what mattered were external factors that "happened" to be correctly aligned.

It worked here.  Maybe your newer version of Android was specifically programmed to more intelligently find number matches (ignore trailing Ps and Ws), which would kill this method.  ...a more powerful tactic for you would be to add a trailing W and a digit (W instead of P so that you are not prompted to release the last digit).  There is no way Android should ever combine numbers differentiated that way, since the trailing W#(...) is how some people put in numbers with different extensions.  Some uses of the number might not like the trailing "extension", but it is worth a try.

I added W1 but then calling that number didn't work anymore...

Wow.  Google must really be attacking this in newer versions then (though I can't imagine why).  I just tried dialing with an appended "W1" and an appended "P1", and the calls did go through.  (How can you ever program in a number with an extension if they break it like that, by the way??)

Side note:  I confused P and W in my comment from earlier today.  P is for pause (for about a second) before releasing the next part, and W is for wait for me to opt to release the next part.  So if you can get it to work, you want P.  Again, though, they both work for me.

Stopped working again in cm10, with no apparent reason. Workarounds are no good anymore, but unfortunately I guess there's no real solution either :/

Trying to Make WIFI connection on android 4.1 jellybean
New Nextbook tablet Android 4.1 Jellybean.  trying to make WIFI connection.  Ensured that SSID is enabled. Password entered.  Device says its obtaining IP address, then avoided poor internet connection.  How to I fix this?

See: “Avoided poor Internet connection” even though signal strength, speed is great, What does “avoided poor Internet connection” mean?. (This question might not be a 100% duplicate, because apparently the presence of the “Avoid poor Internet connection” setting is manufacturer-specific.)

Your router may have a pairing button that you need to press. If it does, it must be pressed  the first time you attempt to make a connection. Be close to the router. Turn off Wi-Fi, and hit "on" again. Go to Settings > Wireless networks > Wi-Fi.
My router is a Cisco Linksys X2000, and I had problems too.

I had this issue and all online guides failed, i eventually downloaded kingroot and it fixed it when i did "optamize" in that program and "activate game mode".  If you have any battery saving apps or use kingroots Purify sub-app, do not "optimize battery" as one of the things it does is affect the wifi as that is a battery drain, so switch off any "optamize battery" features in any apps.
This worked for me.

Reject calls with WhatsApp message
Is there any app or any way to reject a call with a message sent via WhatsApp? Normally when we get a call there is an option to reject it with a pre-written SMS, but I was wondering if you can use WhatsApp to send these template messages.

IMHO: That's very much up to WhatsApp to support such a feature. If it doesn't, file a feature request for it upstream.

I think part of the point of blocking someone is not letting them know you've done so. If the blocked number is a bot/machine it would probably won't do much with a block message. either way it's basic enough feature to request it.

Looking at WhatsApp FAQ, it looks like this feature is currently NOT Supported by WhatsApp.
In Summary, When someone calls you, you will see an incoming WhatsApp call screen. And you can tap on the message icon on the call screen to decline the call with a quick message.
But for Above steps to work, the Incoming call HAS TO BE WhatsApp Call and NOT the regular cellular call.
Hence, currently user needs to use native/in-built app Like SMS/Hangout to Reject call with message.

There is a app for android to cater your need.
https://play.google.com/store/apps/details?id=com.berightback&hl=en
What it does?

Install the app and enable accessibility for BRB.
Enable service.
Once you reject a call, the app helps you to compose a personalised WhatsApp message on your contacts chat window. You just have to tap send.
Apart from this, it reminds you to

If your phone is rooted, you can use Tasker to do this. Set up a profile that runs on missed call and triggers a task that runs the shell commands listed here: (http://tasker.wikidot.com/whatsapp-send-message). Just ignore the AutoVoice commands used to get input and hard-code the message you want sent.

I made this app with the exact requirement as yours, I hoope you like it
Reject Calls With WhatsApp Message

The link is dead, can you please take a look at it?

@GokulNC Link updated. The app was stuck in conflict with whats app, Now we are clear. Enjoy the app

Is there a way to make a page in the Kindle app less brighter than the options available within the app?
I have my bright setting on the lowest in my app and my phone is at the lowest possible brightnes too but I find it too bright to read a page in the Kindle app in the dark.  Is there any way to lower the brightness? I only find that the Android stock browser's lowest brightness setting to be bearable in the dark; even the lowest possible brightness setting in Chrome is too bright.  Is there some radical way to make the brightness in the Kindle lower than the default?
Samsung Galaxy S3
4.1.1

To break the upper/lower limits of device settings, you'd most likely need to tweak your ROM, which requires the device to be rooted. I know there are some solutions for volume limits around ("booster"), so I won't rule out they do exist here as well.
To work around system settings at the "lower end", as it is your intention, you might e.g. want to take a look at Screen Filter:

Applies a shade that acts as a dimmer to ensure your eyes don't hurt. Far more powerful than Android's built-in brightness setting. Great for low-light gaming, web browsing, and eBook reading. It even saves battery life for AMOLED displays!

So this app uses a trick by adding a semi-transparent layer on top of what's displayed, which makes the display appear "darker".
Then there's also Night Mode, which has a similar goal (and uses a similar method to reach it):

Night Mode's main goal is to reduce the brightness of your screen lower than you can achieve with the default settings.
This application applies an overlay filter that acts as a dimmer to darken the screen and ensure your eyes don't hurt.

Pick your choice -- or check for another. Where there are two, there might be more (Super Dimmer, Screen Dimmer, Screen Filter, ...). A Playstore search will be your friend here (note that that's also all what I did -- I didn't use any of those solutions myself, so no guarantees :)

I quite like Twilight - basically overlays a translucent slightly orange layer on the screen at night. Very similar to f.lux for the pc, although slightly buggy at times

You can change the brightness in the Kindle app by touching the "Aa" icon near the upper right. This will bring up the font, size and brightness settings, which you can then adjust to your liking.

I have that at the lowest setting possible already. And, my phone is at the lowest setting too.  I was looking for something to alter this...

How can you go any lower than the lowest setting!

I've heard some people say you could through the OS but I'm not sure about any details...

Maybe, but that's a completely different question than the one you asked.

This is great! It was very frustrating to see that the system brightness did not coincide with my book's brightness. On this screen you can also say that the brightness SHOULD match the system's brightness.

change the background colour to sepia which will appear less bright or even wear sunglasses!

I think the OP was looking for a more, um... technical solution than "wear sunglasses".

@Chahk:  Sunglasses are an easy solution.  It takes only seconds to put them on or take them off; that's probably less time than it takes to enable a screen filter app.  If the OP has a pair of sunglasses handy, this is a quicker and better solution than using a screen filter app.  I've upvoted this answer.

Same thought here Upvoted

Access to my location (let apps use your location information)
VZW location services
Standalone GPS services
Wi-fi & mobile network location service

Is there any reason why it shouldn't work?

Go to Settings>Accounts>Google>Location Settings and turn "Let Google apps access your location" on.

didn't work for me. am about to let go for an iphone 5c. it is a turn off not to have GPS on my galaxy s4. The one in the car broke down.

Windows can't identify Samsung captivate glide
I've Samsung Captivate Glide (i927). When I try to connect the phone to the PC windows says USB Device unrecognized. I've installed the latest version of Samsung Kies, and also installed Samsung_USB_Driver_for_Mobile_Phones_v1.5.14.0 from the official Samsung site. Still I cannot connect my phone to the PC.
I tried to install the Samsung mobile composite driver manually also. It installed successfully but gives an error that the device cannot start code 10. And again the phone is detected as "Unknown device".
I've also tried to change the PDA USB mode in phoneutils by *#7284#, still no luck.
Can anyone tell me how to solve this problem? I'm using Windows-7 Ultimate 32-bit Desktop computer.

Finally got solution after 2 days of headache. Problem is my USB data cable. I've got original Samsung's USB data cable with phone but unfortunately it is not working. Though charging can done via this cable. I've tries few Chinese cables also but problem remains there. But as soon as I use my friend's original Samsung cable it working like a charm.
So any of you have this problem first thing to do is check from another usb cable. And importantly go for OEM's original cable.

How to Install Android OS on mobile
I bought Android phone called KUBAO  (Chinese phones model)
Its says that it has Android Version 4.1.1
But its in Chinese Language in menu & when I change it to English language then its shows some items only in English version.
Now I need to install fresh Android copy on my mobile.
[ I mean like format PC and install linux or windows on my PC :) ]
I heard some words like root phone is it mean format phone.?
Please send me a link to download Android OS also if i'm following incorrect link.
I used this link for download Android OS
I have USB cable and SD card for use with phone, but haven't got an application like PC Suite. I downloaded MOBOROBO which I can use as a file explorer, but it doesn't have the permissions to create or edit files in Phone memory.
Here is a picture of the phone:

Please help me to sort out this issue. I use Google but I got only results for install android OS on PC :-) so I think here is the best place to resolve me problem

Firstly, this is a XY problem: You don't need to install Android, but you want your language problem fixed. I've adjusted your tags accordingly -- just follow the "faq" link on "languages", and find on the top: How do I add a new language?. If you really want to install Android anew, please check Where can I find stock or custom ROMs for my Android device?.

"Rooting" does not mean formatting your phone.  "Rooting" means getting access to functions on your phone that normally only your carrier or manufacturer has access to.

You can't install Android like Windows or Linux - every handset is a little bit different due to hardware and carrier changes.  You could call technical support for your phone to find out how to change the language (easy option), or find a ROM to install that has what you want (much harder option).

It sounds like you don't actually want to format and reinstall Android on your phone, all you really want to do is reverse all of the changes that you've made and set it back to how it was when you first got the phone.
Android is set up differently from Windows so that you should never need to format it and reinstall the OS. There are two halves to the storage, there is the System partition where the Android Operating System is installed that is read-only, and there is a separate User partition which is where all of your settings, changes, apps and data are stored. This is why your file explorer can't edit files in the Phone Memory, it's for safety to stop you breaking your phone and to stop you ever needing to reinstall the OS. All that you actually need to do is wipe your User settings.
A "factory reset" is how you clear off all your changes, settings, apps and data and get things back to how they were when you first bought the phone (make sure that you back up your data first. In the Settings app you should find a menu option called Backup & reset, if you go into there you should find an option called Factory data reset this will do the reset back to defaults for you.
For more on what terms like root and reset mean, please see this previous question: What is the difference between: Rooting, Jailbreak, ROM, Mod, etc.?

Android Folder Hierarchy
On Android's root (/), what is the purpose of each folder? I want to learn the folder hierarchy structure. I would like to know the differences between Android 2.3 and 4.x, if they have different folders in "/".

Related, for Jellybean (4.1+) What kind of data is stored in /data/user directory?

Android Partitions and Filesystems

First, you need to be aware of two facts:

Android uses more than one file system (think of "multiple drives/partitions" when comparing with your computer
while sharing a common base, directory structures might differ between manufacturers

So as starting points, I further recommend the file-system tag-wiki and the partition tag-wiki (you might also want to take a look at the most frequented questions using those tags).
In my answer, I will concentrate on the mentioned "common base". However, there still might be deviations made by some manufacturers.
Partitions
As said, Android makes use of multiple partitions. In the file system, they are represented by "directories", which serve as their mount-points:
┌─────────────┬───────────────────────────┐
| Partition   | Explanation               |
├─────────────┼───────────────────────────┤
| /boot       | kernel & Co.              |
| /cache      | app cache                 |
| /data       | user data partition¹      |
| /data/data  | app data¹                 |
| /dev        | devices²                  |
| /mnt/asec   | encrypted apps (App2SD)   |
| /mnt/emmc   | internal sdcard³          |
| /mnt/sdcard | external sdcard³          |
| /proc       | process information²      |
| /recovery   | used in recovery mode     |
| /system     | system ROM (read-only)    |
└─────────────┴───────────────────────────┘

¹ Details below
² virtual file systems
³ these might differ. Often, /mnt/sdcard is the internal SD card, while the external SD card is found in /mnt/sdcard/external_sd.
Above list is far from being complete, but should hold the most important partitions.
Directories
Here I again will concentrate on the partitions which are most interesting (or this answer would get far too long and, for most readers, boring.
/data and /data/data
These are in most cases two separate partitions, but there might be cases where this is handled otherwise. One thing they have in common (add /cache here as well): they get wiped on a factory-reset, while the other partitions are usually left untouched by that.
As for the directories contained, I will again concentrate on a selection; most things here you either cannot touch without having your device rooted.
┌────────────────────┬──────────────────────────────────────────────┐
| Directory          | Explanation                                  |
├────────────────────┼──────────────────────────────────────────────┤
| /data/anr          | traces from app crashes (App Not Responding) |
| /data/app          | .apk files of apps installed by the user     |
| /data/backup       | Googles Cloud-Backup stuff                   |
| /data/dalvik-cache | optimized versions of installed apps¹        |
| /data/data         | app data²                                    |
| /data/local        | temporary files from e.g. Google Play³       |
| /data/misc         | system configuration (WiFi, VPN, etc.)       |
| /data/system       | more system related stuff (certs, battstat)  |
| /data/tombstones   | more crash stuff ("core dumps")              |
└────────────────────┴──────────────────────────────────────────────┘

¹ for details on the Dalvik cache, see: dalvik
² each app gets its own data directory assigned here, using the app's package name. There might be a similar directory on your SD card, mostly used by apps with larger amounts of data.
³ usually, files are stored here temporarily to be installed/executed. Google Play e.g. downloads .apk files to this directory, before installing the downloaded app on your device

Of course, I intentionally skipped several directories. If you really want to go into details, this site might not be the best fitting place (as we deal with end-user questions -- and end-users normally don't touch these things). In that case, several places/resources might be recommended:

XDA Developers
good technical books on Android (e.g. Andrew Hoog's Android Forensics and Mobile Security, which goes much deeper into details here)
Where can I ask questions that aren't Android Enthusiast questions?

Rest still hold true, except /cache is not app cache. It's used for OTA updates in recovery mode. /recovery and /cache both removed on A/B devices.

Why is adb backup with system apps unsafe? (Holo backup)
In holo backup, adb backup with system apps is said to be unsafe. I was and am not sure why it is. But I tried it anyway, and slept then when I woke up in the morning, my computer crashed. So I am wondering what is going on. (I tried other "safe" adb backup methods, and they did not crash my computer :) )

I doubt two things here: first, the crash of your computer is unlikely to be meant by that statement (I won't say it was completely unrelated, but at least rather a co-incidence). Second, the backup is unlikely to be unsafe – it's rather the restore to be concerned about.
Searching the web, you can find plenty of reports where a restore "broke the device", and left the user with crashing apps, not being able to read/write SMS, and things like that. Such happens especially when that backup was restored to a different ROM, or even just with some OTA in between. Structures might have changed, database layouts looking different (some columns dropped, others added), so "stuff" is no longer compatible with the backup. A restore would simply place the old files back, and thus might change parts of the system which now consist of more files/apps.
All those problems are rather unlikely to affect "self-contained user apps", but quite often happen with system apps. I hope this little excurse sheds some light.

Why does the number of apps "optimized" not reflect removed apps?
I've read the details on what optimizing does here: What kind of app optimizations do newer Android versions do at the first reboot?
And my question is slightly followup.
I run CM nightlies on my TF700T using TWRP to flash and erase the Dalvik cache each time. I understand the Optimizing process rebuilds the Dalvik cache, but it appears it tries to rebuild the cache using every single app I've ever installed, not just the ones currently installed. The total number of apps it optimizes never goes down, always up.
I presume this means there is a list somewhere in the system with all the apps this process must go through. Is there an app or utility that can update this list and justify it against a list of apps actually installed?
Or am I making incorrect assumptions and is this process also running through system apps that are not subject to user removal?

When Android optimizes apps it will optimize all apps, including system apps that you cannot see/remove (well, technically you can, but that's a different question).
If you just check the installed apps on your phone it will just show you the apps that YOU have manually installed and that is why the number is not the same.

This is not entirely correct. The Apps view includes installed and system apps. Though this may be a recent development.

Buttons stop working in landscape mode
I wanna buy a second hand tablet (Pierre Cardin 7558) whose home and return buttons stop working when tilting to widescreen. The quality is good in comparison with the price, but there is this problem.
Is there any workaround to it? Like a Rom update or something?

The buttons are disabled so that users can grip the sides without causing and action. It would be difficult holding the device if the user is causing the device to go to the home screen.

Thanks.But why should they be shown if they're not there to be used?

You said that they are disabled on widescreen so, they work on regular screen.

It is also easier to simply disable a button than to also remove. Lazy programmer maybe?

So it means that's the same thing in most of tabs, am I right?

I am starting to think that I am not understanding your question. Can you clarify what you are wanting to know?

Actually it's a second hand device and the one of the reasons the seller i giving it away is the buttons not working in widescreen.

Why is EXT3 not supported on Android?
Android uses the Linux kernel instead of some "Android kernel", so why is ext3 not supported on Android 2.3?

The filesystem support is device-specific, and in fact many devices using Android 2.3 support ext3 in the kernel (or ext4, which can also mount ext3 and ext2 filesystems).
Usually the difference in filesystem support is due to different hardware. Older devices often used raw NAND flash chips and MTD drivers in Linux, which did not support conventional filesystems such as ext4; only special filesystems such as YAFFS or JFFS2 could be used on such devices. In this case having ext3 or ext4 support in the kernel was not necessary, and it could be omitted to save some memory; to get ext3/4 support on such device you will need to flash a custom kernel (or, in some cases, an external module could be compiled instead of replacing the whole kernel).
More recent devices usually use eMMC storage, which provides a block device instead of raw flash; such devices mostly use ext4 for their filesystems, and therefore should have support for mounting ext3 filesystems (although actually using it to mount a custom filesystem, e.g., on a separate SD card partition, will require root access).

Is there any version of gtalk supporting multiple accounts which works with 2.3/cm7
Gtalk 1.3 doesn't support multiple accounts: it just connects with the main one, with no apparent way to switch it.
Upgrading to hangouts technically works, but it doesn't even bother to display user online status, so I'd rather have a real chat app.
Do I have any other option, running on 2.3.7 / cm 7.2.0?
If it isn't an official gtalk version, I'd appreciate if at least it was as good, integrated and non-bloated as it is, such as:
• integrated with address book
• downloads whole conversation (as opposite of just displaying new messages)
• plain and simple

Did you ever tried IM+
I still think hangouts is better, but since you don't like it may by you could give IM+ a chance. Now it will not download all your previous chats that you had on talk, but after you are logged in it should display all messages that you send, recive, even if you are not directly sending them from your phone.

How can I open an epub+zip file on my S3?
I got some files that say "epub+zip" undrr Properties and I wanted to know how can I open it?
OS: 4.1.1

You need an ebook reader that reads EPUB files. Aldiko (http://www.aldiko.com/) is a great ebook reader that supports EPUBs. Or, you could rename the extension to zip and extract the file. Inside, you will see some folders. Within one of the folders are HTML files that can be viewed in a web browser.

you can use kobo. It is an app for reading. I usually email myself the epub file then go into the email where the file is located on the right hand side there will be 3 little dots click that to save and then go into the kobo app and click the phones menu button to import the epub files to your kobo app and then it should show up in your kobo library.

Link to the app would be nice.

How do I play Flash websites on my Samsung Galaxy S3?
Is there a way to use flash-based sites on Android? A browser? Radical app? I want to play videos on this site:
http://www.onf.ca/explorer-tous-les-films
OS: 4.1.1

One of the answers on http://android.stackexchange.com/questions/32948/how-can-i-use-flash-player-now-that-its-no-longer-supported may help.

@DanHulme answers there are for Gingerbread. Are you sure they work for JellyBean as well?

No. Nor am I sure they won't. That's why I said they may help. I hope the OP can confirm either way.

OK -- so I've added a solution that should work on JB. Though I didn't try it myself, as I have no need :)

I hope it's okay to answer my own but I thought it might be useful to others.  I found these looking around more: Photon browser and Puffin browser.  Both play Flash sites without all the complicated installation of Adobe.

It would be helpful if you posted links to the apps you mentioned. Please use the link tag. :)

There's a HowTo at MakeUseOf.Com describing how to install Adobe flash player on JellyBean. Excerpt:

Enable unknown-sources on your device
Grab the .apk for flash player from XDA-Developers and save/copy it to your SDCard
Use a file manager (such as e.g. ES File Explorer File Manager), navigate to the place you've stored the .apk, and tap the file once. This starts the installer.

Once the installation is finished, you should be able to play flash again. However, not every browser might support it. The very same article mentions how to enable flash support in Firefox:

Open Firefox, tap the menu button and open Settings > Plugins and choose Enabled.

That way you should be able to use it with your favorite websites.

Oh no, I don't have an SD card.  Why doesn't Android support Flash, anyway?

Not even an internal SDCard? Your device certainly has a local place to copy stuff to.

Oh, yes the internal one I have....I thought SD always meant external.

Yeah, one should think a card is a card. But manufacturers think otherwise, obviously :)

Install Adobe Flash Player for Android.
Use Boat Browser as your Android browser. Enable Flash via Settings > Page content settings > Enable flash/plug-ins.

This is what I did to enable Flash on my Samsung Galaxy S4. No luck with stock browser and Dolphin.

Any stability issues?

@verve Nope. It's works as expected. I tried a Dolphin beta version which allegedly had Flash support, but it didn't work. Boat Browser is your best bet. I'm using it (and Dolphin too!)

Firefox version 21 installed easily but greasemonkey won't install - error saying not compatible with ver 21
I can't find anyone with this problem of not being able to install greasemonkey since installing Firefox version 21 on my android. My ultimate goal is to combine my fitness pal logging with weight watchers so that mfp will calculate ww points. It can be done but only through using greasemonkey. Any help is greatly appreciated :)

Have you also tried the latest developer snapshot from https://addons.mozilla.org/de/firefox/addon/greasemonkey/ (scroll down to devel channel to see 1.10b1)? Besides this: your problem seems rather app specific, I suggest you better ask over at mozilla.

The error message in this case is misleading: it's not that Greasemonkey is incompatible with that version number, rather that it's incompatible with Firefox for Android. The extension mechanism in Firefox for Android is somewhat different to Firefox on desktops, so add-ons for desktop Firefox won't work (in general) on Android.
To find out if/when Android support is planned, or to help out, you could start by contacting the gresemonkey-users mailing list.

Thanks! Apparently my issue can't resolved after doing more research. I appreciate your input though :).

How can I troubleshoot MTP on my Galaxy Nexus
My Galaxy Nexus 4.2.2 won't show up as a MTP device anymore. It looks like the phone is the problem, I want to debug the problem from that end.
Like many before me, I tried everything, and then some :

Using Ubuntu 13.04 or Windows 7, on 3 computers
Cleaning the USB port on the phone
Using the original cables
Reboot with or without the cable, with or without the SIM card
Removing the battery all night (after shutting down the phone) to clear everything from memory
Uninstalling Google Play Music (I only use MTP to sync music)

I also have a second phone that shows up as a MTP device and syncs just fine. It is also a Galaxy Nexus running 4.2.2. Neither of them are rooted. So I think the phone must be the problem.
How can I troubleshoot or debug MTP problems on the phone ?

I see the /dev/mtp_usb kernel driver, which led me to this patch. But how do I know if the mtp_usb driver is working on the device ?

Android shows missed calls even after open
My phone shows the missed calls on the app icon even after I check and delete them from log. I did restart / battery off several times but it still hanging there!! Phone Samsung Galaxy S Duos Android Version 4.0.4

Screenshot (click image to enlarge)

Are you saying about seeing notifications on notification area and pushing clear button? Did you try just to click on the notification and then on back key and to do it repeatedly until all notifications disappear?

go to settings > application> all > badge provider> clear data & clear cache.

I have had the same problem on my android phone but tried a solution from one of the android forums which says
Go to settings>>Applications manager>>all applications (on the top) locate the badge provider app, once in there clear data and restart your phone.

Try removing the icon of the app from the home launcher then put it back then restart your phone

Does the Galaxy S2 have two mics?
I need a straightforward answer, does the Samsung Galaxy S2 have two microphones? I tried to Google it but was not too successful. Two mics are essential for my upcoming project. Thank you for all your replies.

The Samsung Galaxy S2 does have dual microphones.
However, if using Gingerbread (2.3), the device only records mono audio.
Using Ice Cream Sandwich (4.0) though, the device can record stereo audio at about 130 Kbps with a sampling rate of 48KHz.

It does have a dedicated 2nd microphone for active noise cancellation according to GSMArena.

Google Keyboard vs Android Keyboard (AOSP)
Is there a difference between Google Keyboard, which was recently release on the Play Store, and the Android Keyboard (AOSP) in the open source project?
Update: I need the difference from a feature prospective

It's exactly the same keyboard as the Android Keyboard from Jelly Bean (4.2) as I read.
See i.e. this article.
Rereading exactly points out that this app should expose the keyboard which was only installed on Nexus phones with Android 4.2 to prior android version (4.0+) on other smartphones and tablets including features like "swiping" and gestures.
There is another article on Androidcentral

My AOSP keyboard let me long press some of the keys for punctuation.  I could hold "m" to get a "?" and now I no longer can on the Google Keyboard.

You can press the 123 key and whilst holding it slide to the where the m key was, which will now be displaying a ?  This is a quick way of getting to the numbers, too.  Likewise, you can slide from the shift key to capitalise a single character.

This is probably the CyanogenMod keyboard, which is titled Android Keyboard (AOSP) and has the symbols on every key.

As far as I understand The AOSP keyboard is available in CM Roms, its called 'stock' keyboard when you flash CM based ROMS. As for Google Keyboard, it's the official one on Nexus devices. I personally like the CM (AOSP) Keyboard. It allows me to long press keys for punctuations, I'm very used to long pressing 'm' for '?' and 'z' for '!'. It is irritating that I can't do that on the Official keyboard. I also can't find a separate APK for the CM (AOSP) Keyboard

There is EnhancedIME which is apparently the AOSP keyboard with some enhancements: https://forum.xda-developers.com/android/apps-games/enhancedime-aosp-latinime-enhancements-t3366639

To be clear; I am not looking for a "Threaded view". A threaded view groups emails on the basis of subject, but does not include my own emails in that conversation. What I need is a way to view the emails as a conversation in which all emails, including my own, are listed.
Does anybody know how I would be able to view my emails on Android in conversation view?

How can I increase the number of volume levels?
Is it possible to increase the number of steps in the volume control? I'd like a finer grained control over the volume level. I have a Galaxy Nexus.
Note: I don't want to boost the volume just change the number of levels so I can find a sweet spot when listening to music.

There is also the (easy) option of using an external volume control, like a Koss VC20

In the situation where the lowest level is already too high, a practical workaround is to use an equalizer app and attenuate all frequencies equally.

Many people have this problem with Android. You can see it has been reported in Android's bug tracking system. The number of levels is controlled by a setting that's compiled into the Android system image.
Use a different ROM
It's possible that flashing a custom-rom could increase the number of levels, but I don't know which, if any, custom ROMs do this. This bug report in cyanogenmod's tracker suggests they don't plan to add that feature, for fear it may cause compatibility problems with some apps.
Use a different app (easy)
Some media apps have their own volume control, on top of that provided by Android. I believe Poweramp is one such (but I don't use it myself). If there's one particular app you need more control of, such as a music app, you might want to replace it with one that has this feature.
Edit your phone's OS (advanced)
If you're not worried about the risk of breaking some (badly-written) apps, and your device is rooted, then you can follow these instructions to edit the Android system image to increase the number of levels. That site gives step-by-step instructions, including installing the developer tools you'll need to make system changes; a summary for knowledgeable people is as follows:

Get framework.jar from your device and run baksmali on it.
Edit framework\android\media\AudioService.smali
Search for 0xft 0x0t 0x0t 0x0t to find the table of audio levels.
Replace the first number of each row with the desired number of levels (in hexadecimal).
Run smali to generate a new framework.jar, and then replace the original on the device.

This should help some folks and it does enable better control, not louder volume.

Go to developer options (enable developer options if you haven't previously done so).

Then, turn on "Disable absolute volume".

You may need to restart your Android device for it to take effect.

The steps now are way more reasonable. In other words, it answers your "Note", as now the volume (at least on my Bluetooth headphones) now has much smaller steps -- it no longer goes from too quiet to too loud in one step.

How did you get this to work?  I tried it just now (using Bluetooth headphones) and noticed no difference at all.  Are there any additional steps (e.g. disconnect or forget, then reconnect Bluetooth device; reboot phone; something else)?

No sorry, for me it just worked after I did that. I think I did have to restart my device first though. But I had to enable absolute volume again as it meant some devices were crazy loud. It would be nice if Google just fixed this / gave you options to handle devices that need more steps! :(

After a restart it seems to have worked.  The headphone volume control used to be tied to my phone's media volume; now they're separate.  I still only have 15 levels of volume control in Android, but being able to adjust the phone and headphone volume separately gives me much better control of the volume than before.  Thanks!

This should be the official answer (thank you!).

For me, it didn't change anything at first, then at the next day, it worked. The indicator if the setting is applied was when the volume display on the phone wouldn't show up anymore when the volume button at the bluetooth speaker was pressed (Android 10). It worked on the next day, so apparently I needed to turn off/turn on the device or reconnect. No Android reboot was done.

If you're phone is rooted or you have a custom recovery (like TWRP), this is actually much easier. The only thing you'll have to do, is to add the following line to your build.prop file located in /system:
ro.config.media_vol_steps=30

Where 30 represents the number of steps.
This can be done with a root file explorer (like Root Browser) or via VI in the TWRP terminal or via adb.

Restart is needed after changing this value

When trying to edit build.prop in File Explorer Root Browser's internal Text Editor, nothing happens. I get a blank screen with the logo of Text Editor in the middle. Any idea why?

I ended up using Fine Volume Control V2 (Trial version) on my Nexus 4 - supports up to 100 volume levels.  It's not perfect but should suffice till they hopefully fix what seems like such a simple problem.
Precise Volume (XDA Forums, Play Store) also looks worth a go.

Alas, this may have worked back when this answer was written, but it doesn't seem to work anymore.  On Android Pie (9), even though the app displays changes of 1% volume, the actual volume jumps in a way that suggests it's still hardware-locked to the idiotic 15 levels of Android volume.

I had initially posted this as an answer to this question: How to increase/decrease volume in smaller increments/decrements?,
unfortunately this method won't work officially with Nougat (due to some missing requirements)
The workaround:
As expected, such a modification, will require root or some kind of zip flashing proceedure to install Xposed framework.
Kuba Kalamarz created an Xposed module called VolumeSteps+ which allows one to adjust the amount of steps for every system volume function.
The good thing I noticed about this module is it binds to settings system (i.e you don’t have to open the module UI, instead you can control via the volume button)
Prerequisites

Root
Xposed Framework
Unknown Sources enabled

Features

Change the number of volume steps for the alarm, music, notification, ringer, system and in-call streams.
Ability to change it to somewhere between 5 and 50 steps

How to find my stolen galaxy ace duos
I lost my galaxy ace duos. The sim card has been changed.  How can i trace phone or find the number of the new sim being used? I have several apps installed. can that help in anyway? Thanks for the help

Also possibly relevant: Find a stolen Android device without sim card

Samsung Galaxy Ace Duos has Android 2.3 installed, so you should be able to use Plan B.
This app sends the location of your phone to your email. Of course this requires your phone having a connection to Google play with your account.
In general: saying 'I have several apps installed' does not help, providing information what apps are installed maybe does.

Thanks very much. I have installed Plan B. And I pray it will be successful.

Does the play store still show the provider and mobile information, if the google account is removed/changed
Basically what I would like to know is will the play store web version still show the provider and mobile information ie [This app is compatible with your PROVIDER_NAME DEVICE_MODEL.] if the device is factory reset/rooted/removed the google account/change google account.
Thanks in advance.

Old devices stay in your list in the Play Store for quite a while after performing any of those actions. I gave one of my old Android phones a factory reset and then gave it to a relative a few months ago, they then registered it on their Play Store account, but it still showed in the list on my account for a few months afterwards (but I couldn't push apps to it from my account any more).
See also this previous question where an old device has been factory reset'd and still appears in the Play Store list: Deleting a device from the Google Play Store?

None of those actions (factory reset/rooted/removed the google account/change google account) will have any effect on your provider or device information.

Encryption and Screen Lock without SIM card
I'm have a Samsung Galaxy S3 running Android 4.1.2 which I am trying to encrypt through Settings -> Security -> Encrypt Device. The process I am following is described in this article at Step 2.
Upon entering the Encrypt Device screen I am told to "Set an unlock password". How is this password set? My first guess was the Android Screen Lock, but within Settings -> Security I have no Screen option as I would have expected (shown in above article at Step 1). Could this be because I am using the device without a SIM card? If so, is there any other way of using this encryption method, potentially with an inactive SIM card that is not connected to any network?

The screen lock is set in Settings -> Screen Lock. The device can then be encrypted without  SIM card.

How safe is the android Lock Screen with password?
If your tablet got stolen, how probable is it, that the thief will retrieve data from your device if you have only the lock-screen with a 4-character password as protection?
Is it easy for a hacker to get past that? Or can I lean back and be sure, that stored passwords in Firefox etc. cannot be retrieved?

I had a Galaxy Tab v10.1 GT-7500 that got stolen yesterday ;/

I wanted to know, so I tried entering my password incorrectly repeatedly. (Motorola Droid 3 - Android 2.3.4)
After 5, 10, and 15 attempts I was given a 30 second "cool down" where I could not try again.
On the 15th attempt I was informed that if I entered my password incorrectly 5 more times I would be forced to re-sign in with my Google Account.
So after 20 failed attempts, you can no longer try to enter a password - you must sign in with your Google Credentials.
I would say you are reasonably secure from a brute-force password log in at the password screen.
This does not take into account any other methods - just attempting to brute force.
This answer may address methods that could be used to bypass the lock screen.
To specifically address your concern about Firefox for Android's stored passwords - you can disable Firefox Sync on a lost tablet (Mozilla's Instructions) by changing your sync password. Mozilla also suggests changing all of your passwords after it.

So it seems, there are some phones out with vulnerabilities to some hacks. But I couldn't find out, if my Galaxy Tab v10.1 GT-7500?

A lot of the bypass methods require your device to be rooted, or have USB debugging enabled - or to have access to your Google Account. If you weren't rooted, or had USB debugging enabled you can be reasonably assured of your security. The other exploits involve receiving a phone call.

I had a phone card in there, but it only works for SMS; And it was not rooted.; The Mozilla suggestion only disables future passwords to be transferred to the stolen device. Passwords already in there are not deleted, if you change the sync password. So my main concern is that the thief gets access to my passwords already stored in Firefox

That is why Mozilla suggests to change all of your passwords after changing the master sync password. The passwords present become outdated and useless.

I couldn't change them all. I have about 500 passwords in my password manager! Not so many important ones though, but still: they should not be revealed to the thief. But that's all off-topic. The thing is: I still wonder if it will be possible for the thief to see them or not.

google play store says no connection retry
When I open the Google Play Store it says, no connection retry even when I am connected to wifi and when I hit Sign In in the Youtube app it says, An error occurred.

Have you ever been able to get to Play Store (or other Google services) on this phone?

See also: Why does Google play show a "no connection: retry" error?

See also: Always seeing "No connection: Retry" in Android Market

See also: Google Play Store gives error "No Connection"

See also: Internet Apps are not working but browser works just fine and i am able to access websites

Read thIs , it helped me . mIne was the date was wrong. http://wccftech.com/fix-no-connection-retry-error-message-on-google-play-store-app/

You checked your internet connection of the modem/router? I also got that problem several times.. > modem/router/ap restart helped me in this cases because it was a connectivity issue with my provider and not an android/app problem.
Sometimes even a simple turn into flight mode and back resolves this issue (at least for me).

To decide whether it's your router or rather the Android device, it might help checking the colors of your connection icons in the notification bar. If they are white/gray, the Google servers cannot be reached (so it might be the router/AP). If they are green/blue, the Google servers are reachable, so it's more likely something "messed up" on your device (in which case the flight-mode-switch might help).

The browser works

If you're using a firewall app, make sure you've allowed the Play Store (or whatever other apps) in the firewall rules...AND that you've saved/updated the rules.
Apps like Android Firewall won't actually make the changes until you've chosen to 'Apply rules'.

Mine Solved..
Some times your network blocks ip's or google may black list your network ip's for some reason..
If setting date and time, clearing data and cache doesn't work. Install VPN HotSpot Shield via browser. Than turn this app on once it secures your connection you will be good to use play store.
Hope this helps.

Is there a way to disable the default calendar app on a Samsung Galaxy S4?
I'd like to use the standard Google Calendar app (as available in the Play Store) too keep track of events.  However, Samsung includes a modified version of the calendar on the S4.  In previous iterations of the Galaxy it was possible to disable the Samsung version of the Calendar app so that I wouldn't get duplicate notifications of events.  On the S4, it does not seem possible to disable the app or it's notifications (the "disable" button and "show notifications" checkbox are greyed-out in the app info screen).  Is there some other trick I can use to disable the Samsung Calendar app?

Are there any in-app settings that allow you to customize the notifications? If you're rooted, you might try using Titanium Backup to freeze the Samsung calendar.

I wonder why Samsung feels the need to put on his phones apps that are so hard/impossible to uninstall/disable.

Assuming your end goal is just to get the app to shut up (i.e. not get double calendar notifications for all events), all you have to do is disable the alerts and notifications from within the app itself.

Go into the App
Press the menu button
Choose Settings
Scroll to the bottom
Change Set alerts & notifications to off

For good measure, I also unchecked Vibration and set Select ringtone to Silent, but that probably wasn't necessary.
The app will still be on your phone, but aside from the icon being there you won't even notice it unless you open it.

I just tried this but it doesn't seem to keep my settings for more than ~2days. Every so oftern it turns notifications back on.

@Steven10172 I'm not sure what could be causing that.  Mine has been disabled for almost a year now with no issues.  It could be a bug in the software, I've got version 4.3-I545VRUEMK2 according to the App Info.

I have been having the same problem as @Steven10172 for 4 months. I set the notifications on S Calendar to be Off. then at some point they turn themselves on again. I suspect that it is happening whenever Samsung pushes out an update to S Calendar and it is resetting my notification preferences. But not sure about that.

@shaune, do they push updates that often? And it used to work until my phone upgraded.

@Steven10172 No I suppose not. Now that I think of it that doesn't make sense. I guess the only thing I have been able to figure out is that like you every week or so my settings get reset somehow. I will try paying more attention and will update if I have anything else.

@Steven10172 Early this week I found this post which says that Luke's solution should work as long as you check "All calendars" in the main Calendar app and then turn off notifications. I noticed that I had a few calendars checked and a few not checked. After checking "All calendars" I haven't had the problem again (hasn't been terribly long but still better than before). I did have to go into the Google Calendar and adjust which calendars I wanted to be displayed after. http://forums.androidcentral.com/verizon-htc-one/311635-cant-disable-stock-calendar-notifications.html

I have a Galaxy s4; even after disabling the notifications, they turn on again whenever I reboot my phone.

On my Galaxy Tab A7 the "alert and notification" button for Samsung calendar is missing.

I disabled it in the Application manager under settings. I don't get any notifications at all and I just use the google calendar app.
I do have a it f a problem though, if I click a invite link it still opens the S planner... haven't figured out how to avoid this yet, but the app is mostly out of the way.

On my Galaxy s4, the "Turn off" button in Application Manager is greyed out.

On my Galaxy S4, Google Calendar complains and wants the default calendar re-enabled.

On my Galaxy Tab A7 the "turn off" button is greyed out too.

Root:
You can install Titanium Backup to uninstall unwanted apps easily.
Without Root:
After doing some research to uninstall apps without root, I found an interesting article which  helps you creating a script to remove certain stock APK files.
Check it out here.
To simplify it, copy and paste this for step 7 (though I'm not too sure if those are the APK files for the stock calender. You mean S Planner, right? Anyway, let me know if it works):
ui_print("S Planner remover for the S4.");
ui_print(" ");
ui_print("Partitions mount");
#Properly unmounting to avoid issues
run_program("/sbin/busybox", "umount", "/system");
run_program("/sbin/busybox", "umount", "/cache");
run_program("/sbin/busybox", "umount", "/data");
#Then mounting
run_program("/sbin/busybox", "mount", "/system");
run_program("/sbin/busybox", "mount", "/cache");
run_program("/sbin/busybox", "mount", "/data");

ui_print(" ");
ui_print("S4 default Calendar remover");
delete("/system/app/SPlannerAppWidget_NAmerica.apk");
delete("/system/app/SecCalendarProvider.apk");
delete("/system/app/SecCalendar_NAmerica_SPen.apk");

ui_print(" ");
ui_print("Unmounting partitions");
run_program("/sbin/busybox", "umount", "/system");
run_program("/sbin/busybox", "umount", "/cache");
run_program("/sbin/busybox", "umount", "/data");

ui_print(" ");
ui_print("Finish");

does this work? it looks promising!

This can't remove Samsung Calendar (it comes right back), but it can Freeze it.

In Galaxy s4.

Go to Calendar
Menu
Display
uncheck "My Calendar", "Samsung Calendar", Samsung Task"
select "Done" in right top corner

You now have stopped visual of Samsung Calendar. You can add Google or if already added, your Google Calendar will display your events or appointments you set.

Clever solution... leave s planner running, but give it nothing to work with.

This also turns off the calendars on Google Calendar.

It would appear that Root App Delete can disable S Planner. Seems to work so far for me.

This works, but your link is no longer valid.  Just search the app store for Root App Deleter.

I've created a simple app, that hides all notifications from S Planner when they appear.
https://play.google.com/store/apps/details?id=s.planner.sucks.and.stinks
It seems to be the only working solution for my non-rooted Note 3, I've tried everything suggested in this thread with no luck.
Edit: with Lollipop update, you can finally disable S Calendar totally, it's hidden inside system options.
Edit 2: with another update to my Note 3 system, you cannot anymore. But I discovered a wonderful pm hide command, that will work even on system apps on non-rooted devices. You need Android developer tools installed, then you run this command from ADB shell:
pm hide com.android.calendar
and you're done, it seems to be persistent between reboots.

You would want to mention that pm hide is specific to Lollipop and above. For Kitkat, there is pm block and no similar solution for earlier Android versions. I have some details of the command covered here.

Regular voice calls stopped working, was earlier. Maybe Skype related. Android 4.0.3
I have a Samsung Galaxy S II with Android 4.0.3.
The problem:
It was working fine until today, for both voice calls and Internet use, as well as for Skype calls. (I had installed Skype for Android on it some time ago after buying the phone). But only used it for Skype calls once or twice.
Since it supports both regular voice calls and Skype calls, when I go to call log in the Phone app, and touch or swipe a contact name to call them, it earlier used to give the option of calling that person either via a normal phone call or via Skype.
Today, while trying to call a person, I think I was absent-minded and may have accidentally pressed some wrong option. As a result, from then on, when I try to call a person, from the call log list in the phone app, it does not show the normal call option and the Skype call option for me to choose from. Instead, it directly goes to Skype and tries to do a Skype voice call. So I am now unable to make regular voice calls with it.
I looked in the Skype app settings as well as in the Call menu under the main Settings app of the phone, but could not find any way to restore the earlier behavior, where it allows me to choose whether to make a normal phone call or a Skype call. I also looked at all other options in the main Settings app, at the top level, but could not see any other menu that seemed as though it may be relevant to fix this issue.
Any suggestions on how to solve this?
Thanks.

You have multiple options to solve this:

Go to Settings->Apps, scroll to Skype, open it, and hit the "Clear Defaults" button
If that for some reason does not work: simply install some other VoIP app, try to call a person again (now you should be able to chose), hangup, and remove the other VoIP app again
Try Default App Manager Lite, DefaultApp Reset, or similar apps to reset single default actions
Chuck-Norris-Mode: try Clear default app for action to reset all default actions
Last ressort: uninstall and re-install Skype

All above solutions should reset the default app selected. Besides: same procedure works for multiple web browsers, home screen replacements (launchers), image viewers...

I tried your option 1, and it worked. Thanks a lot for your help. Earlier, I had gone into the same option (Settings -> Apps, then Skype, but had not seen the Clear Defaults button, because it was below the visible area of the screen, and there was no scroll bar, so I thought there was nothing below Cache.

Glad to read! As it solved your problem, it would be nice to mark the answer as "accepted solution" (just click/tap the checkmark next to it, below the up/0/down buttons). You're also welcome to push the up arrow as well ;)

I marked the answer as accepted, but for voting up, I tried, it says you need at least 15 rep. So cannot do it. Sorry. Thanks again.

No prob, and you're welcome! The "accept" shows this is the solution that worked and was preferred by you, which makes it easier for other affected people to recognize it. The upvote says "it's useful" -- which an accept already includes. Two more points (editing a post would do that), and you will be able to do that for answers you like :)

Wasn't expecting another answer so didn't check this article again after your comment, sorry. Only happened to look at it again now. Anyway, thanks again for the info and meta-info :)

Small keyboard in landscape
I love Swype, but it has one big problem: it's almost impossible to use in landscape on a 5-inch screen. It just gets difficult to run my finger correctly across the keyboard when it's spread out across the entire screen.
Is there a way to restrict the width of swype (or virtual keyboards in general) when in landscape mode? I just want it to retain the standard layout of the portrait keyboard.
Running a fully rooted and customizable Nexus 4.

Thanks for clarifying your question. I don't think it's possible in general, but I don't know about Swype in particular.

@DanHulme I'm pretty sure swype has no option of this sort, that's why I was asking about keyboards in general. I was hoping there might be some hack that forces the keyboard to stay in portrait even if the device is in landscape. But it was just a shot in the dark anyway. =/

SwiftKey has this feature nowadays, and supports gesture typing like Swype.

It is possible in Swype to change the size (width) of the keyboard, and shrink it. Press-hold on the Symbols key ("?123"). There will be options to change the keyboard size. Drag your finger to the icon showing the size you may want (on the left side, right side, floating...).

May 2013 Gmail app update: "Reply as" multiple accounts gone? (Android 4.2.2)
I have two gmail accounts hooked up to my Samsung S4. When I go into the Gmail app and compose an email, I'm given the choice to send as any email address associated with either account. It used to be that I could reply to any email from any address as well.  So for example, if someone sends something to my work address I could reply to them from my personal address just by selecting the account from the pull down at the top.
Now it looks like I can only reply, reply all, or forward an email from any email address associated with that one account.  So I can only reply from my work addresses if the email was sent to a work address; I can only reply from my personal addresses if the original email was sent to one of my personal addresses.
This seems like a major loss of functionality!  Especially when Android will "share" from the last email account touched, it seems important to be able to quickly select which address to reply from / send from.
Can anyone explain this behavior?  Is this a problem for anyone else?  Is there a way around this?  Thanks!

It seems like you only do that on iOS and desktop according to their help page.

Installing incompatible ROMS
I was wondering if you are able to install ROMS, for example, the Ubuntu Touch OS for the GS2 i9100 onto the GS2 SPH-D710. Will it brick my phone?

If installing incompatible ROMS wont' soft/brick your phone then what would?

Magic would....

Do you know any? I'm very jealous of S4 that I see around me.

Any good ROMS? Not at the moment.

No Magic that would soft/brick the phone.

In general, no, it is not possible to flash ROMs made for a different model.
Specific to your device, no.  Flashing ROMs for the I9100, I9105, I9100G, I777, and T989 on you device will result in you having a phone-shaped paperweight.
You can find appropriate ROMs for your device here, among other places.

Thanks. Didn't want to install Ubuntu on my Epic 4G Touch and have it bricked.

WARNING   THIS WILL COMPLETELY UNROOT YOUR DEVICE AND YOU WONT HAVE WIFI
BUT IF YOURE USING DATA, YOUR FINE
BUT YOU SHOULD KNOW HOW TO FLASH STOCK BACK ONTO IT IF SOMETHING GOES WRONG.
Yes you can actually all you do is extract everything from the flashable rom, then go to META-INF/com/google/android/updater.script.
Open it with any text editor. Go to any of the lines that say something like this: (getprop("ro.build.product") == "i9100). Then change the model number already on the line to SPH-D710. now, go and recompile the rom. Then reboot to recovery and install.
                         WARNING
Since you are using an SPH-D710, The wifi might not work, I realized that after installing cyanogenmod 12 lollipop and tried cyanogenmod 13 also and wifi didnt work on either and only the search button and back buttons work. I dont know if the rom youre trying to install has options in settings to edit what your buttons do, but cyanogenmod did. So if youre going to try it with cyanogenmod then just do all the instructions the same.
And please tell me the results If you plan on doing it so I can add that to my list of compatible roms. Thanks.

How do I stop the "which browser" window from popping up every time I try to open a new page in the stock browser?
My stock browser never used to have this problem until I downloaded the Puffin browser and the Photon browser today.  So, every time I type in a URL or open a new window in the stock browser I get the "select which browser" to use with the "always" and "once" button options.  I wanted it to stop popping up so I click "always" but after that I don't know how to proceed. Chrome doesn't seem to be affected. How do I fix this?
OS: 4.1.1
Samsung Galaxy S3

Probably uninstalling the other browser would work, though you probably don't want to. It looks like the stock browser is asking for any of the applications to handle the tab, and then the android system isn't remembering the decision (Or the stock browser is making a unique request each time). Probably only way to fix is to remove other browser or to modify the stock browser in some way.

Could you clarify some things, please: Did you check the "always" checkbox, or did you just think about? If you did, what changed (or what didn't -- as you "don't know how to proceed")? Is this problem restricted to the stock browser only, and are you just talking about working inside that (i.e. clicking a link while in that browser, typing URLs into that browser's URL bar, etc.)?

@ Izzy: Yes, I click "always"  then it says go to "settings" but when I go to the "appications manager" to select "all" or whatever it says to do after pressing "always" I don't see what I 'm supposed to do exactly.  Yes, only with the stock browser; every time I click a link the popup shows up asking which browser I want to choose.

Automatically wake and sleep device on timer
I have a vanilla Android tablet running Jelly Bean 4.2.2 with root access. I've set this tablet up as a photo frame using daydream. Is there a way via settings or an app that can automatically sleep the device or display at a certain time and then wake it back up at a different specified time?

Explore an app called Tasker. You can also check out its tutorials and guide to know how.

While I second Narayanan (I'm using Tasker myself), there are multiple automation solutions available in the playstore. Tasker is worth every cent, but there are also free solutions like e.g. Timeriffic or Llama - Location Profiles which might be capable of that. Check the related section on their playstore pages for more :)

Guys, please consider posting these comments as answers, so they can be upvoted, and so the question will stop showing as unanswered. You've both been on the site long enough to know the comment box isn't for half-assed answers.

How to see mobile operator proxy settings
My mobile internet suddenly has stopped working. Chrome complains Error 130 (net::ERR_PROXY_CONNECTION_FAILED). Google app store and other apps those load content from servers now work only when I connect through wifi.
I set in firefox about:config network.proxy.type from default value 5 (use system settings) to 0 (no proxy) and firefox has started working.
Proxy Settings app shows empty fields.
As I don't use any proxy I would like to see that system wide proxy setup which broke my mobile inet

In Chrome, navigate to chrome://net-internals/. Does the Proxy section give you any useful information?

For GSM devices, as far as I know, the proxy settings for your mobile data connection are defined in the Access Point Name (APN). Go to Settings > Wireless and Networks > More > Mobile Networks > Access Point Names > [Your data APN] (your device's menu may differ slightly). Check the Proxy field - it's possible this got modified somehow. Might also be worth snooping around your carrier's website for the recommended APN settings and double-checking that everything is correct. Once finished, press [Menu] > Save and give it a test.

I somehow missed these settings before. Thank you! I don't know how proxy server got 'qq' value. Guess my little kid had set it when was playing angry birds.

Did you switch from "Mobile data" to "WLAN" (also "Wifi" or "Wi-Fi" on SAMSUNG) last time for surfing in internet? If yes, then try this!
Sometimes when you enable "WLAN"  before disabling "Mobile data" (top line, near the battery-charge-state or the current-date/time) the proxy settings for GSM will stay and be used for you WLAN!
All you need to do is:

Disable "WLAN" (also "WiFi" or "Wi-Fi")!
Enable "Mobile data"!
Start Chrome and navigate to somewhere or search for something!
Can you surf? If no, switching from "Mobile data" to "WLAN" was not the issue, else:
Disable "Mobile data" and wait 2 seconds!
Enable "WLAN"

It should work now.

Check the properties of your Celular Network configuration. Sometimes it has a proxy and port configured. Delete them.

I've had the same problem and the suggested solutions haven't worked for one reason or another. However, I thought "Perhaps there's an app for it?" There is! It's called Proxy Settings and the icon looks like stacked books. Search for it and install it via the Play Store app on your phone/open it/click on your wifi network/turn off the proxy setting. Internet access via a browser should now work like a dream.

Welcome to Android Enthusiasts! This answer might be more helpful if you add a link to the app you're recommending.

That could be my first question! How? copy and paste via the edit button doesn't work for me. Have I really got to write it down and then type it in?

Need to reset the proxy to default.
Then its working.
Step 1: Use user SIM network
Step2: Go to Access Point names
Step3: Go to the INTERNET options and make proxy as not set.

Fixed mine. I get this ERR_PROXY_CONNECTION_FAILED every time I use mobile data.
You need to reset the APN to default

Tablet not connected to N wifi
I have bought a cheap tablet, and it was not able to connect to my N-only wifi. When I set it to NG or G, it connected fine. So I took it back to the shop and had it replaced. The new one has the same problem. I have tried several channels and even disabled the encryption on the router, nothing helped.
The interesting part is, I asked my neighbour to change his network to N-only, and the tablet connected to that one.
Both of us have TP-Link routers, mine with DD-WRT, his with stock rom. 3 other android devices and a Win7 laptop connects to my N-only wifi without problems.
G is fine for browsing, but not enough for streaming.
Any suggestions?

Have you configured the N-only network to use only the 5GHz bands? It may be that your device only supports the 2.4GHz bands.

The router is not capable of 5GHz. Can it happen, that the tablet only knows 5GHz?

No, since then it wouldn't connect to G-networks either.

How do I know if a phone knows 5GHz?

Do you have an XBox?

No, I have to wired Win7 computers, 3 phones, and 1 tablet. The laptop usually stays at work.

Making Android phone locked using the SIM card password
When I press the power button. the Android phone will go into sleep mode.
When I press the power button again, the Android phone will wake up and ask me a password.
So, how do I make the Android phone ask me the password that belong to the SIM card instead of the phone itself?
What I mean is that the SIM card was locked with a password. The phone itself was not locked with any password (also not locked in pattern password). So, how do I make the Android phone prompt me the password of the SIM card every time when I wake it up regardless if I just power up the android phone or I just wake it up from a sleep?

Is there a reason why you don't want to just set a password and make it the same numbers as your SIM password?

because I don't want to change the password two times (one time for the SIM password and another time for the phone) for every month (cause I change my SIM card password every month)

If your goal is better security, then by using the same password for phone and SIM lock, you are actually making yourself less secure for the sake of convenience.

Chahk has a point. Having 1 password for both defeats the purpose have having one for each. If I get the password I have access to the entire phone, rather than just the phone/sim.

@BlaineAnderson I do agree that if it is for security sake, then it would defeat the purpose of having 1 password. I was just wondering if Android have such feature (or function). If Android does not have such function, I really don't mind setting 2 password.

Restoring APKs + data from 4.1 to 4.2.2
I migrated from Android 4.1 (Omega) to Android 4.2.2 (SuperNexus) on my Samsung Galaxy S3.
Before I did the migration I did a backup of apps with Super Backup. After this was done I moved all the files from the SmsContactsBackup folder to SDCard.
After flash, I've installed Super Backup again from the Play store and putted the SmsContactsBackup folder in /storage/emulated/0/SmsContactsBackup. Now I see all the backups in the Super Backup app.
After I do a restore/install of an app, the settings are not being picked up by the apps.
Plague Inc.: I see the settings in data/data/com.miniclip.plagueinc. But the app crashes on launch.
Lazors: I see the settings in data/data/net.pyrosphere.lazors. But my progress is gone.
Do they need to be somewhere else? Or do I need to use some other tool which can use my previous backups

Essentially, for backing up apps or SMS, TitaniumBackup works wonderfully. I've always relied on it to get my job done. But since you've already backed up your apps, I'd suggest you to try moving your app data folder to storage/emulated/0/Android/data/ folder instead of where it is now, and if it is a .obb folder, move it to /Android/obb. It'll pick up your settings.

Sadly, this doesn't fix it. Will a TitaniumBackup of an app in 4.1 work in 4.2.2? I still have a nandroid backup of previous ROM. But I also changed the recovery...

Yes, it will work. TitaniumBackup creates a folder in the sdcard for backups and as long as you have the folder, it will work well.

Correct, I now did the backups with TitaniumBackup and everything went well. Thanks :)

Samsung Galaxy S not displaying contacts, only unknown is shown
My Galaxy S Duos only shows unknown on the display when I have saved phone book contacts calling me? How and what do I do to get numbers to be displayed?

See also: Sony Xperia Z won't name contacts on incoming calls

How are you saving your contacts? For example, if I save on my phone 12345678 and 12345678 calls me is is shown normally, but if I save it as 0123412345678, where 01234 = 0 + operator 12 + local area 34, sometimes it is shown as unknown. I tested it with my two SIM of different carriers and it occurs in different ways for different carriers...

After some investigation I found a fix that works for me.  Use this at your own risk.
First, the summary:  The file /data/misc/rild_ril.clip is a single byte,
either ASCII '1' or ASCII '0'.  Somehow this value is being flipped from '1' to '0' during low storage space conditions and causes the problem.  The solution is to either edit the file, or just delete it and let it be rebuilt.
The steps to fix this problem on your device without losing any data are as follows:
Requirements:
ADB or a terminal/console application.
Steps:

Get to a shell prompt.  If you're using ADB, it's adb shell.  If you're using a terminal/console app, just launch it.
Type rm /data/misc/rild_ril.clip.
Reboot the phone.

That's it. Please let me know if it works or doesn't work for you.

Lock-screen information lost calls etc
At my company we use Sophos MDM solution, witch forces all user to set a PIN on their lock screen. I use a Samsung S3 (android 4.1.2) and the lock screen is only a huge numeric key pad. The oterones using iPhone can have their phone to show lost cals, incoming mail, sms etc as a banner on the lock screen.
Is it possible to have the same features on my Samsung device? Is it possible to customize the lock screen?
Have tried to download some apps, like GO Locker, but they appear before or after my lock screen so it doesn’t work as intended

Dashclock widget is an amazing app to let you view missed calls or notifications right from your lock screen for Android 4.2 and up. Since you're still on Android 4.1.2, install WidgetLocker lock screen and use it.
