usb otg for motorola mb865 at&t 4.0.4
Hi i wanna watch tv on my lapdock, this is what i have:
Motorola Lapdock 500 PRO
Motorola ATRIX 2 MB865 AT&T Android 4.0.4 +root
DVB-T Reciever for Android - CSL - mini DVB-T Stick (requirements - android 4.0 or high, dual core cpu (neon support) usb otg)
Handmade Y. USB OTG cable  (powered by wall adaptor)
After using chainfire diagnostic app for fix otg, I able to mount 2gb usb stick to phone, and can access files. means otg fix succesful and otg cable also works fine. Chainfire after check returns what is on screenshot

Then when i connect DVB-T Stick to phone by otg cable (else, if i connect it direct to microusb port - system not find device. possible just by otg cable) system popup message:

But after open Air Dtv (any other app which works with dvb stick simply cant find device) i get this message from app:

Reconnecting returns same error

So what's the problem?

after using chainfire diagnostic for fix otg, i can connect usb stick to phone, by Y. otg cable. and can access usb stick files in filemanager, delete/copy/paste etc.
but Air Dtv programm returns "initialisation failed, reconnect dvb stick and check again" when i try to connect csl dvb-t stick to phone.
it returns that only when i use Y. otg cable, else it not find device, if i connect it direct to microusb port
Screenshots can show usb information also, on xda board link

means i able to mount 2gb usb stick by otg cable. it works well. but same try, for connect dvb-t stick returns error

The Y cable would be the first suspect then. Since the Lapdock has its own USB ports, try connecting the DVB receiver to one of those (if the DVB receiver is USB-OTG you may need an adapter).

Also, [edit] this information into the question, so that it's easier for other visitors to see what the actual problem is. You're more likely to get relevant answers that way.

Y cable works cause i can mount 2gb usb stick by it, and able to access files.
dvb-t stick package contain microusb(female)-usb(male) adapter, i try connect dvb stick to lapdock using this adapter - device not found. looks like external power needed. just want first finish it succesful on phone, then try on lapdock

Cannot connect to my WiFi: "Saved, secured with WPA /WPA2"
I cannot connect to my WiFi at all. I have a Nexus 5 and it has been fine for a long time. All of a sudden, I just cannot connect to my WiFi. I try to connect, and it either says that I am out of range, or that my connection is secure. When I enter my passcode, it just doesn't connect, gives no error or anything. It just keeps saying secure connection. I am on KitKat, the latest version.

How far are you from your wifi router?

Next to it really.

Does this happens to other devices who are connected to your router?
And does it happens to your device when you are on another wifi router?

I don't know if this is an Android issue, so much as a WiFi problem. A while ago (before I got my Android) I had some issues connecting my computer to my WiFi -- my computer sensed that the network was there, but wouldn't connect. I was advised to reset the network.

Unplug all parts of the network: router, modem etc.
Hold your breath for ten seconds.
Reconnect everything.
Try connecting to your network again.

This worked for my computer; give it a try for your phone, and tell us what happens.

I give my neighbors guest access to my personal router. They have Android Fire HD and another generic tablet. Their connection goes out periodically (work outside on the lines did it once). My home network (iPhone, Macbook Air, Lenovo/Arch) will be fine, but their units continue to attempt to connect. Restarting the router did the trick. Very strange.

I get this very regularly, and the problem is usually down to the router but occasionally the Nexus.

In WiFi settings, "Forget" the connection details.
Reboot the router and phone.
Once available, connect to the network again and re-enter your details.

On my Nexus 7, entering a static IP fixed the problem when I was at the edge of WiFi range, but as you say you're near the router this wouldn't seem to be the issue you're having.

This typically happens if you aren't near the router or have put an incorrect password...

No Internet when another Android device is connected to router
Like the titles says, i have a weird problem.
I have a brand new device A (Android phone V4.2, manufacturer is called "Vivax"-not very popular outside Europe), which is having problems accessing internet.
Internet works only if there is no other smartphones connected to router.If the other phone (some older Samsung) is connected, there is no internet access on the device A.If i disconnect the Samsung device, turn wifi off and back on on device A, it can browse internet.
But if the other phone is connected, there is no internet access at all.
I checked the router and i think it is using WPA2 encryption.Also, there is no IP address conflict.
Anybody have any ideas what could be the problem?

uboat55 seeks clarification: What if you reserve an IP for device A on your router?

by reserving I guess uboat55 means to .. suggest the use of static IP address. you can configure your router to work with static IP address instead of a dhcp service.which I also feel should do the trick .
configure your router with fixed IP address and latter use that IP address.
or you can even try to assign IP address directly to ur device A. without changing any thing on the router part.
just remember the IP address range.
eg
192.168.1xx.xxx to 192.168.255.254
and chose any one IP address within that range .
and remember the default subnet I.e 255.255.xxx.xxx or something similar
and the router IP address and use this on ur mobile .

Quickly turn on / off lock screen?
Is there someway to quickly turn on / off the lock screen without delving into the settings?
Most of the time I want the lock screen, but when using the device to play music / the radio I'd like quick access to the full app without needing to unlock my screen each time.
Ideally when something is detected in the headphone jack I'd like the ability for the lock screen to be disabled first time the screen is unlocked, or if already unlocked when headphone jack is used simply disable the lock screen.
Or perhaps there's a widget I can add to my home screen to quickly turn on / off the lock screen manually?
Any ideas?

Turning OFF your screen via widget is possible (and several widgets are available for that). But turning ON the screen cannot work that way, as to access the widget, it must already be turned on. Of course you could use a lockscreen permitting widgets (like C Locker Pro).
An alternative is using tasker, and defining a corresponding profile:

Condition: Headphone plugged
Task: Disable keyguard

This is the most convenient way, as you only had to turn on/off the screen via the power button. And apart from that, you get yourself a powerful companion for your device – just check the tasker tag-wiki and other questions using the tasker tag :)

Tasker looks like the way to go. Thanks for that as I was unaware of Tasker before!

You're welcome – and good choice, as Tasker is the answer one can give to every second question :) There's a free 7-day trial on their homepage if you want to check first. Enjoy!

From playing - seems Tasker can't disable the keyguard, only show the settings screen with keyguard options on?

Might that depend on Android version? Works fine for me (on my 2.3 & 4.0 devices; I've got that in my "nightstand" task: when placed in the docking station, it shouldn't show the lock screen but my nightstand, so it needs to "disable keyguard"). As Google/AOSP tends to remove features like this (just think of "apps no longer allowed to trigger airplane mode"), I could imagine that being the cause. You could try whether the Secure Settings Plugin helps here (as it might be device-dependent instead).

I have duplicate contacts, Google Contacts not helping!
I have several contacts in my phone which are duplicates. For example I have one contact "John Smith" which contains my friend John Smith's phone number. Then I have another contact name JohnSmith87 which is my friend John Smith's email address. And then I have another contact called JohnSmithin which is my friend John Smith's skype account. I'd ideally like to merge all of these into one contact. I tried Google Contacts, but when I searched, only contacts with a phone number stored in them would show up. Please help!

I have a quick step-by-step guide to help you "join" your contacts - in other words, take two separate contacts and make them one!

Open the People application.
Navigate to one of your duplicate contacts (any one will do) and tap it to open it up.
In the top-right corner, tap the 3 dots. This is the settings menu. Select "Edit".
Again, in the top-right corner, tap the 3 dots. Select "Join".
Android will now ask you to select which contact to join this contact with. Select one of the other duplicates of this contact and Android will join the contacts into one contact!

Rinse and repeat until all of the duplicate contacts have been "joined" into one single contact.

I don't think this applies to the Google Contacts app for Android.

About Google Contacts, are you sure that JohnSmith87 (the contact with no phone number) is not in the Other Contacts section?
If that's the case, you can select the contact, click the "Add to my contacts" button and than go back to My Contacts section.
Now you have both contacts and you can select them and merge.
I find much more easy and quick to manage my contacts from the web than from my device.

Gingerbread 2.3.4 To Gingerbread 2.3.5/2.3.6
My Mobile Is A Galaxy Y. The OS is 2.3.4 Gingerbread. what i wanna do is Update it to 2.3.5 / 2.3.6 . By Updating Will I Loose My Applications Which Are On Mobile?

It depends on the update. Over-the-air (OTA) updates do not wipe your data, so you should definitely accept such an update if there is one. Updates which you have to flash yourself (e.g. using Kies) usually do wipe your data, but the documentation that comes with the update will confirm whether it does.
Installing a custom (third-party) ROM almost always requires you to wipe user data.

Its definitely a YES as Dan has rightly said and as its a Samsung Device you will mostly do the update through Kies (comparatively easier when compared to other update) so just make sure you have the backup ready before doing the update and have a 100 % charge for a successful update.

How to read contact details sent from iphone?
When someone with an iPhone sends me a contact, it appears as a blank MMS message. I found that this happens because group chat is on on their end, but these people are not always my friends, so I can't tell them to turn it off.
Is there a way to read these messages?

Some Android devices does not have support for handling MMS or SMS vCards in their native texting app. That is why you see it as "content not supported" or even blank message.
You can use third pardy app to handle MMS vCards if your Android device does not support it by default too. Search on Google Play. I've created such an app bizCard Manager. There are plenty more that handle SMS vCards but I've not found any that has MMS support.

Try Textra. This texting app also allowed me to import vcards in existing messages.

Only 1 arrow flashing when connected to wi-fi
Recently when I connect to my companies  wi-fi network, it  says I'm connected with 1 bar the up arrow flashes white but the down arrow does not flash at all and I can not use any apps internet, nothing! (I never had this problem before)
Can someone please help. I have reset my phone, turned it off and on 100 times , clicked forget network and retyped in password etc.. says I'm connected to network but no internet?
I use Samsung galaxy note 2

Is anyone else facing this issue or only you? It probably is a firewall that is preventing you from connecting to the internet.

Sounds like a problem with your work Wi-Fi network. You should ask the IT support helpdesk.

Here's your solution to the only one arrow of wi-fi is blinking issue

long press your wi-fi network, an option will appear 'modify network' click this.
Go to advanced setting and change your Ipv4 address from 'static' to 'DHCP'.
After this also if your problem is not solved then contact to wi-fi owner.

your firewall is preventing your phone to access or connect to the internet.check your firewall settings. or may be this happen due to some problem in your router.

Welcome to the site! It's great that you're trying to help, but I wonder how much use a suggestion to "check your firewall settings" is. If the questioner didn't already realise that, they probably need more specific advice about what settings to check.

how to clear RAM on the click on a button?
I need some help regarding the performance of my phone. I have to clear RAM every time to free some space through the task manager. Can anybody please help me clearing RAM on the click of a button?

Why do you have to clear RAM? It's bad for performance to do that, so you should only do it if there's a specific need.

+1000 to @DanHulme's comment. See this for reference: Why You Shouldn’t Use a Task Killer On Android

You've already (and correctly) used the ram tag. Please, take a look into its tag-wiki, and check its notes. Especially follow up to Are there guidelines on how much free RAM a phone should have?. Important Mantra: "Free RAM is a wasted resource". Repeat at least 10 times before breakfast for the next 3 month (feel free to continue longer) :)

Android's RAM management has gotten quite good over the years, but if you really need to free up ram, I recommend this app: Taskmanager. It also features a widget to put in your homescreen.

HTC One won't play any video after update
My Android HTC One is currently running Android Version 4.4.2, a few days ago it updated a bunch of apps, about 27 I think. I honestly can't remember which updated and which didn't.
Since then it won't play any videos. It won't play any video files from my memory card and it won't play any videos from YouTube, Facebook etc...!

Screenshot (click for larger variant)
A similar error pops up for every application.
Has anyone else encountered this issue?

I've got what I think is the same issue with my Nexus 4. I can't pin down exactly when it happened, but it's likely to be around the latest OS update. On YouTube I get "connection to server lost \n Touch to retry" but I can still successfully chrome cast the same video. Does that describe your problems? (I don't want to create a duplicate question)

@Mike My problem was across every video player on my HTC One, chrome cast, youtube and even the the playback feature for videos I had recorded myself. Different errors for each piece of software but none of them worked. I took Husman's advice and went over the list of apps I had updated and for the in the comment section of the youtube app, there were several comments from people with the same issue I had. It seems as if the youtube app was behind it, (but no one was too sure). I just restarted my phone and the issue seemed to resolve itself.

You can go to the play store and view the 'my apps' section. This should list your most recently updated apps. You can check the top 27 or so and see if it helps you determine, which one may be affecting video playback.

ah cheers Husman! I'll chk that out asap.

If you are using a third party video player of your device,say, VLC Media Player, then go to setings>Apps>Manage Apps>VLC>Clear Data, and reset the data.
Once done, use a system cleaner app like Cleaner Master and clear the Junk on your device. This should solve he problem.
If the problem still persists, opt to reinstall the video player app.

Cheers for the reply Kanishk but I haven't installed any third party video player. As far as I now, it's still using the video player that came with it.

Turn your phone on and off it worked for me

Stop a mailbox syncing between 9am and 5pm
I have my work emails set up on my LG G3, but when I'm at work I don't want to be getting notifications on it whilst getting them on my laptop as well.
Is there a way to stop a mailbox from syncing for a particular period? E.g., from 9am to 5pm?
I still want my other accounts to sync and notify me though, like my personal/other work email addresses.
Is there an app that can handle this? I've just come from an iPhone 4s (yesterday) so I'm still getting my head around the Android ecosystem.

That sounds like a perfect job for tasker (see the tasker tag-wiki for some background). Example profile in "Pseudo-Code":

Condition: Time, start: 9am, end: 5pm
Task: Sync off
Exit-Task: Sync On

Notes:

"Exit-Task" is optional. If not defined, Tasker restores the state from before the Task started.
"Sync Off" applies to more than just mail (includes e.g. contacts, calendars, etc.). If you want to only pause mail sync, you need a mail app with Tasker support, e.g. K-9 Mail, maybe with some additional plugin. I know that's possible with K-9, and it's more than likely there are some other supported Email Apps. If using such a client, replace the "Sync off" / "Sync on" with the corresponding plugin action.

How do I add more locations for weather updates in Google Now?
Currently, Google Now shows me weather updates of my home and work locations. However, I want to add more locations for weather updates. But I couldn't find any setting regarding the same? Is it possible to add locations which are not your home or work? If yes how?

I don't think it's possible, however Google Now will automatically pop in weather cards for the locations where you are traveling (based on mails in your inbox).

S3 LTE keeps rebooting
I bet this problem has been posted many times but my galaxy S3 keeps rebooting the samsung logo over and over again. I've tried entering recovery mode but just when I'm about to select an option it reboots again...I thought it could be the power button so I opened up the phone to see if it's not being pressed down but it looked fine, I even removed the button to make sure(using a toothpick as a replacement button hehe).
So where could the problem be?!

If it's not an empty battery, it's most likely a case for the service. Did you do anything specific before this issue came up? From what you wrote, it's hard to see what could be causing it.

Have you put any custom rom's on your phone?
Could be a bad one which is causing this
Either way your best option is to download stock rom for your device and flash it over via Odin

Nope haven't done anything to it really..it just started acting that way all suddenly yesterday...
never flashed a smarthphone..could you provide me a good step by step guide?

Hi try putting your phone into download mode, using power, home button and down volume all at once, if that work ill provide you with a guide tomorrow morning

Any luck @MizziPizzi

Galaxy S3 showing messages are not sending when they are
Title says it all to be honest
Have a galaxy s3 rooted stock jelly bean 4.3
I've been doing some mods recently (not my own just downloaded)
I've undone the most recent ones I've done as only recently the problems started
Haven't you done a restore via CWM as don't want to completely lose the changes I've made
But text messages are sending but always showing up as sending icon (not actually sent)
Any suggestions?
Thanks

Which messaging app are you using?

Contact+ but same thing happening with stock, I restored a backup using CWM which resolved the issue, now just to find what caused it

Factory reset upon unlocking
For security reasons, I want to be able to specify two lock passwords (or patterns) as follows :
One for normal unlocking the device.
Another one if entered, the device will factory reset itself (and maybe format the SD)
I want this to happen from the main Android lock screen, but with two passwords.

Interesting request.  This would require a device administrator, as normal applications do not have this access.  Personally, I don't know of any apps that have this support...

I do not know of any application that does what you request. Maybe "After Unlock" has a feature like that.
What I would do is make an Android application that is fired after unlocking the phone. The application would request a new password and if it is entered correctly do the factory reset and format the SD if needed.
Check this project for an example of how this could be done: myLock

Its possible with device admin & setting password policy. Im not sure I can post some sample code here or not as this site not for codes , for ex
mDevicePolicyManager.setMaximumFailedPasswordsForWipe(mCameraAdminReceiver, 2);

@MIH1406 If you want more help regarding code I can help you out.

This site is intended for end-user questions, so I would guess that the OP was not looking for code.

Well, personally I don't think that there is any application that can help you in putting the lock over your device when wrong password is entered your device gets factory reset. But yes I have seen that function available over the HTC one M8, if you put the password over the HTC M8 wrong for 5 times it gives you the warning and if you put the password wrong for 10 times then the device automatically factory reset your device. I would say it's not possible to till data but I think if you are hungry for the function like, you can either try creating and application which can do so (but I think that would be whole tough mess) or try getting an HTC one M8.

You might need to root your phone and find a way to add another password. You might need programming knowledge for this.

Down voted simply because it is entirely obvious. If you gave sample code or linked to a successful example, the answer would be have been up voted instead.

Can Android prevent you from using up the very last bit of your prepaid-service credit?
Is there a setting that warns you or prevents you from using up the very last bit of your prepaid-service credit? For example, when you are low on credit, but want to prevent yourself from using all of your credit. This way you wouldn't get into a crisis situation unable to call for help. Does such a setting or feature exist in Android?

By "credit" do you mean calling minutes, data? In newer versions of Android there are controls around data usage, but I haven't seen anything about calling minutes, aside from carrier-specific apps/widgets.  Also, as far as I know you can always dial emergency numbers (e.g. "911" in the US), even if you don't have a SIM card installed.

@Chahk Yes, I mean the credit you have on your account that can be used for calling, texting or data. Because from the moment I hit 1.60 euro, my android phone prevents me making any paid connections. Free connections still work perfectly and other phones still let me use the remaining credit, so my provider told me to "check my phone settings", so that's why I wondered whether there'd be a setting that would do so. I'm completely lost on what may cause this problem.

Check under Settings -> Data usage to see if "Set mobile data limit" option is enabled.  This setting might have a different name depending on your phone and Android OS version.

What phone do you have, and what carrier are you on? Vanilla Android doesn't know anything about carrier minutes or credit, but if you got your phone from the carrier they could have added a setting.

@Chahk mobile data limit is not checked.

@DanHulme im using a huawei ascend g6 and my carrier is Mobile Vikings Belgium. I bought the phone from another courier though. Phones arent sim-locked here so thats not the issue since I could use it correctly for over a month until I hit that 1,60 euro. Im not using Vanilla Android but Emotion UI 2.0 which came with the phone.

Faulty battery status indication
I have a Huawei Honor U8860 with Android ICS. I use two Mugen Power batteries. I always use one battery until it's empty, then charge it to full while using the other battery. Recently Android battery level has started to behave incorrectly. The battery level drops dramatically, then stays at the same level for a long time. I experience similar behavior with all the three batteries I own: the Mugen Power batteries and the original battery.
Below is the battery status chart at this moment. Suddenly the battery level dropped to 3 % yesterday, but it stayed there and I've been able to use the phone actively for another day since then. Clearly the battery is still performing well, but Android gets incorrect information about the charge, sometimes even shuts the phone down.
I tried calibrating with Battery Calibration app, but the problem has only got worse. Any ideas what's causing the problem? How does Android get the battery level? From the electronics integrated into the battery or by deducing from the voltage level? What does the calibration actually do?

Battery drain when wifi is off
I turned off my wifi connection and noticed a heavy impact on my battery life. In a few hours without any usage, it dropped more than the whole day before.
See the drop at end while wifi (WLAN) was disabled:

There are many issues where battery life is reduced when wifi is turned on but not when turned off. What could cause this and how can I fix this? Could it be using some mobile data connection that drains the battery more than wifi or is it a device problem?
While wifi was on, it was actually connected to a network. There is no increase in mobile data usage. No suspicious increase for battery consumption for any particular app. Top consuming apps are:

idle 40%
display 19%
mobile standby 18%
android os 13%
wifi 6%
google services %4
android system 2%

Update: It looks like it's constantly switching between E, 3G, H and H+ every few minutes, even without moving the phone. In 2G mode the connection seems to be stable and the battery loss is gone.

A shaky 3g connection in poor coverage could do that is guess.

@RossC Do you know any any way to detect shaky connections? The icon always shows 3/4 or full EDGE coverage , sometimes 2/4 HSDPA. I live in a big city and I think I can see a cell base station right across the street (I did the whole test showed in the image at home).

If anyone has a guess why the question was downvoted or has any suggestion for improvement please tell me. I'm going to test it with 2G only option enabled now.

If your phone is constantly switching between 3G (HSPA) and 2G (EDGE), it's possible that the connection is unstable and your phone is continuously searching for (better) signal. This could definitely cause the battery to drain quicker than it you had a stable connection. 2G-only mode will probably resolve this. If your phone is rooted, you can automate the setting (via Tasker or Llama for example) whenever you are in that particular location.

Activating the 2G only option solved the issue, indicating a problem with the connection, as mentioned in the comments.
Another thing that solved it (temporarily, until I install more apps I guess) was reinstalling the OS. I only installed few apps and the minimal PA Gapps package (contains only some indispensable apps by Google), which presumably reduced the amount of background data send. Overall battery consumption with 3G enabled is way lower than with only 2G before.
I've also updated the radio firmware, though I can't confirm if it had any effect. It still seems to switch a lot between E, 3G, H and H+ but without any actual data traffic there is no noticeable impact on battery life.
Another suggestion I've found online somewhere is to use an app that switches to 3G only when particular apps like the browser is used and switches back to 2G otherwise.

How can I spoof my mac address on Bluestacks?
My Bluestacks is rooted already with terminal installed. (Busybox 1.21.1)
Thus far, I have tried

Mac Address Ghost - App runs, but simply does spoof MAC
Xprivacy - xposed framework keeps getting seg faults upon installation
# ip link set eth0 xx:xx:xx:xx:xx:xx - Operation not supported on transportation endpoint
# busybox ifconfig eth0 hw ether 00:11:22:33:44:55 - Operation not supported

Has anyone achieved this before or know of a way to change the mac address of Bluestacks?

Unzip initrd.img in c:\programdata\android\ folder (by default). It's a GZIP format.
Next, you should edit initrd file with hex editor.
Find your address,
for example
02C6400100C6400200C6400362C6400473C6400574
And Replace 02:00:00:64:73:74 bytes with your hex bytes (MAC ADDRESS)
https://www.youtube.com/watch?v=8rVumD8tmjg
Gzip initrd to initrd.img and replace original file

and how to change the Wifi MAC address using the above method?

Un-Googled Android Experience With CyanogenMod + Amazon App Store?
I was going to buy the new Amazon Fire store as I completely live within the Amazon ecosystem;  I've purchased apps there, I'm mainly a reader and audiobook listener.
However, with my new AT&T Next plan, I'm getting pretty screwed.
I do not have a Google Account and do not want to create one and do not want to live in the Google ecosystem.  Yet, the Nexus 5 at $350 is very appealing.
I was wondering what issues I might face if I bought the Nexus 5, installed the latest CyanogenMod snapshot, and used the Amazon App store on that phone.  Never installing Google Apps.
Does CyanogenMod out of the box provide a complete "deGoogled" Android phone?

If you install the latest snapshot, you're likely to face many issues. Install a release candidate or stable build instead for everyday use.

CyanogenMod, along with most1 other custom ROMs, only include Android code with a few Google parts - all under-the-hood, of course. They do not include apps such as Play Store, Google Now, Gmail, etc. These apps are available as a separate package commonly referred to as GApps2.
So the answer is yes, you may achieve a "de-Googled" experience if you opt not to flash the GApps package.

1 There are some instances that custom ROMs already integrate the Google Apps, but these are rare.
2 Google Apps

How can i turn off charging when my phone connected to my computer?
I have Android device Samsung S4.
Is that possible to turn off Battery Charging when my phone connected to my Computer via USB Cable.
Any ways to turn off or disable it from settings?

This question has already been asked (and answered) multiple times. Please check e.g.: Disable USB charging / How can I avoid the battery charging when connected via USB? / our search engine ;)

Why would you want to do so? I don't think it's possible, at least on an unrooted phone. You can refer to the below discussions, they might come handy:

https://superuser.com/questions/429097/how-to-disable-usb-charging-of-external-devices-in-windows-7

Write permission on certain paths, like the SD card (extSdCard)
In an attempt to transfer a file from a remote server to an Android device I ran into permission problems.
It turns out that I do not have a write permission at the location of the SD card (/mnt/extSdCard).
I am using SSHDroid as an ssh server on the Android device and vSSH as an ssh client to engage in ssh on the Android device.
Since both sudo and su seem to be absent on the ssh server app (SSHDroid), I am wondering how I can change/get permission to write to the SD card location. Or is root privilege not enough to  change write permissions, and is this thus governed solely by the Android OS, so a limitation of the OS?
What I can do is write to the home path of the ssh server (SSHDroid). This path, however, is very cumbersome and can not be reached from the regular Android file browser. This is the reason why I wanted to transfer the file to an accessible path, like the SD card.
Supplement. The Android version is 4.4.2. The kernel version is 3.4.0-1539356#1.

That's a restriction of Kitkat (they call it "security", but in reality it's rather a "force2cloud"). You won't be able to work around that without rooting your device. Except for chosing your internal SD-Card, because there you can write.

@Izzy If you would have put that in an answer then this question would be an answered question.

Done, with a few more details supplied. I had liked to give you a better answer (with a more convenient solution), but Google forbids that...

Really? I thaught they where a big fan of the open source spirit.

"Just do as I say, don't do as I do". Distinguish between the flowers and the fruits. Proclaimed "open source", Google mixes in a lot of proprietary stuff, amongst others. And "freedom" gets more restricted with each new Android version. But that's no topic for here :)

One of the restrictions introduced with 4.4-kitkat was moving the WRITE_EXTERNAL_STORAGE permission to protection-level "SignatureOrSystem", which means even if requested, a "normal app" (i.e. one you install yourself as "normal user" without any root specialities) will no longer get it granted. So there are very few things you can do to "work around" this:

obviously: rooting the device, and removing this limit
using the app's "personal" directory as storage for your sync'd files (i.e. <sdcard>/Android/data/<package_name>/, as this is the only place an app can write on SD with Kitkat)
using your internal-sd card as storage (as here the limitation does not apply)

What are the downsides of rooting an android device? Does the warranty  become obsolete?

Most likely. In the EU there's a law for that, distinguishing between warranty and guarantee. One of them is enforced by law (and cannot be obsoleted by rooting), the other is a non-mandatory offer of the manufacturer, and with that the decision made by him. Looks differently outside the EU, so no definite answer here.

You can always take the external sdcard out of the device, and plug it into your pc. Most pc don't support the micro-sdcards, but you can use an adapter. More infos here: https://en.wikipedia.org/wiki/Secure_Digital#Micro
If the external sdcard is mounted in your pc, then you can read and write all files on it :-)

It was more kind of an excercise to see how far you can go with ssh on an android device rather than accessing the content on the SD card.

Folder that automatically uploads to phone
Here's something I that I want to do with my Android phone (Galaxy S2, CM9). I'll be happy if someone could tell me whether it's possible, and how.
I often want to transfer files from my computer to my phone. But it's a clunky process. the easiest way for me right now is to use AirDroid, but it's cumbersome. Connecting via usb is cumbersome too, because I need to enable the usb storage thing.
What I really want is this. I want a folder on my computer that I can put files into, and have them automatically uploaded to a dedicated folder on my phone's sd card without any further action on my part. It's important that this won't mean constantly having a heavy program working in the background on my phone, because it's slow enough as it is.
Any way to do that?

FolderSync could come in handy here. Define a "folder pair" (i.e. which directory on your Android device to sync with which directory on your computer), using any of the available protocols (SFTP, Samba, or any other). Then either chose for some "auto-check" (e.g. have it synced every night), or push the button manually. Using the paid version, you could even bring in tasker – which is what I do: "Every night at 3am, when connected to any power source and to MY_WIFI network → Sync all my backups, photos, whatsnots" :)

I'd rather not have to wait until the night, I want it to happen immediately.

Ah, I see now there's a Sync button, so I'm good.

One way you can achieve this is using an app - rSync and use a Tasker job to periodically (or conditionally) upload/download data from your phone. You can refer to rSync's documentation for its configuration and other setup steps. You can configure it to only specify required one way transfer of files.

this feature (syncfolder pc to phone) will be developed in SnapsBackups Android app. SnapsBackups execute backups phone to pc by wifi network and withtout human interaction. the backups will be performed when the system notifies the application that wifi network is connected. SnapsBackups evaluates that wifi is a personal wifi, verify that exist a backup for this network and execute it if necessary.
On a next release, SnapsBackups will allow to sync phone with folder pc. No background activity if not necessary.Stay tuned!

Nice to see this answer, since I've recently downloaded SnapsBackups and I like it. I hope to see this new feature soon, so +1 from me. (@user67521: I assume you're one of the devs...good luck with it!)

I currently have a Moto G and I use Google Drive to transfer files to my device. If I want something to send a file right to my device without cables I use Wifi File Transfer. It's super lightweight and doesn't run in the background. It doesn't have a folder option but I like manually sending stuff right to my phone since I only have 8Gb of storage.
[note] The other answer from user67521 looks promising, I'll definitely check it out!

Dual epub reader
I have started using my tablet for reading epubs and I have found a lot of different versions of the same book.
So, is there any application that allows me to compare, i.e. to see both versions in a split screen?
I thought it would be easy to find this because it is such a useful utility!
I have tried the 10 most used application for reading epubs and no single one allows me to do this.

Please note that recommendations like Is there an app for X are off-topic here (see What topics can I ask about here? for details). For where your question might fit better, you might want to look into Where can I ask questions that aren't Android Enthusiast questions?. With the correct phrasing and details provided, you might try your luck at SR. As this one's really hard to find, I've made the exception of answering it, though.

PS: I've pinged our mods on both ends, asking if this question should be moved over to Software Recs. Hope that's fine with you. Not sure whether they migrate it, though, as SR is still in Beta (and thus no "official migration target").

Marc, if you wish to have your question moved to Software Recommendations, I've just got "green lights" from a mod over there (we'd need to apply some cosmetics to your question then, though). Up to you now to give it a go (or not).

Yes! Of course! I have corrected some minor grammar mistakes. I have no problem in moving the question, as you wish.

Thanks a lot for your updates! I've asked for "the move", so let's see whether it's done.

There's EPUB3 Reader available on F-Droid and Github (not on Google Play – though an app using the same package name exists there, it's not the same, but obviously based on the original developers engine; long story behind that, not fitting here). Its app description explicitely mentions this feature:

parallel texts (e.g., original text and its translation into another language).

Find some screenshots here. Picking one example:

Looks exactly like what you're after.

Exactly what I was looking for! Thank you very much. I didn't knew about F-Droid, so double thank you!
Amazing help that you give.

Glad I was able to help! For some more background on F-Droid (and some other markets), you might wish to read my article here (F-Droid and Aptoide have some apps which are not on Play; the article discusses their security measures, quite impressive). For this specific app, I already had some contact with the devs, which are quite responsive (it was a students project, the Profs answered me when I informed them of the "package name trouble" mentioned above).

Is it possible to change mount points of internal storage?
I have an off-brand rooted tablet built on MT8389 with 8GB internal memory. The problem is that manufacturer partitioned this in some weird way making /data folder mounted to a partition that is only 1GB large. Basically I have approximately 4GB of free space mounted as /storage/sdcard0 but it sits unused while all installed apps occupy /data making the device close to useless as only core apps after updates eats over 60% of available space.
After all Android is just another Linux flavour, so I would expect I could run console and do this:

Copy /data to /storage/sdcard0.
Umount /storage/sdcard0.
Mount /data to the partition that was mounted as /storage/sdcard0.
Mount that 1GB partition as /storage/sdcard0 instead.

Is it possible? How to do it "safely"?
Note that I don't want to change partition sizes - I only want to swap mount points or create symlink to make /data point to a larger partition. In theory this should be pretty straightforward ;)

You probably want to install a script like int2ext or Mounts2SD. Note that these use a second partition on your SD card (generally ext2/3/4 formatted) rather than the main SD card partition.
You can also move apps to the SD card (Settings -> Apps -> "On SD card").

Is it possible to set up an emulator with these specific requirements?
At work we've been given an opportunity to work with some hardware running a (semi) custom Android build. The long and short of it is the app we make needs to fit certain criteria.
Uses TEGRA2, Android 4.0.3 Level 15, and supporting 1366 x 768 res with 90px system bar.
Can I make an emulator to simulate all these? The API level is obviously easy to set up, and the custom resolution, however, I can't see any options to do with tegra2.
As a note they do have a SDK available for this, which may include an emulator, but we don't have a copy yet so I'm looking for a quick temporary workaround until we get a copy.

No, the Android emulator doesn't emulate specific SoCs such as Tegra 2, and it doesn't support Nvidia's instruction set extensions.

Ahh okay, so the closest I can get is the screen res and API version?

Yes, that's what I'm saying.

That is, unless Nvidia has something more specific. They can implement Tegra 2, and almost certainly have an emulator they use in-house to test their own software.

Well to be honest I don't think the Tegra 2 is going to affect our app, it wont be doing anything graphic heavy, mostly just displaying data. I'll see what the SDK has when we get it, and if that doesn't come with an emulator I'll dummy up the closest I can get.

How to choose the correct email address in gmail app?
If I have two different email address from the same contact like:

firstname.lastname@private.com
firstname.lastname@job.com

When I need to send a new e-mail I am not able to choose the right one because it displays only the first part of the email address.
So I can only view "firstname" and the first part of the lastname...
It happened very often with my contacts with the original Gmail app.
How can I solve it?

Does turning the phone in landscape mode show longer address?

Yes it does, but it is longer (only few instants, but if I could solve it I will be happy)

It looks like you can type a few letters of domain name that you want after a space to get other addresses filtered out. In general, you can type several parts of a email address separating them by spaces to find only contacts that contain all specified parts.
For example, if you have the following email addresses in your contacts:
john.doe@home.com
john.doe@work.com
john.smith@home.com
john.smith@work.com

Than you can type something like john.d w or j doe w or even j d w to get only the first one in the auto completion popup.

At the top of your email you will have star, reply, forward and the 3 dots. Underneath that you will have from who, then the time, and to:. On the same line where is shows (to:) there is arrow pointing down, click on that and it will expand and show from and reply-to full address. Should have no problem seeing ending of addresses now.
Good luck!

I am not able to view the "arrow pointing down" (I use standard GMail app)

@Ale that is on Gmail

@Ale the arrow looks like this (>), only pointing downward. I have the Gmail app installed.

in the attacched image you can see I have no arrow in the field. It do not appear if I start to write a name

I think HasH_BrowN is referring to a received email whereas Ale is asking about how to see the full email address when creating a new email.

@bmdixon went back and saw the picture again,  and your right.  There still should be some drop down when Ale types so as to see contacts with that name, when in landscape the whole email address should show

as soon as you type into the TO text field any saved contact with the letters/symbols/numbers typed will show up in a drop down menu. If they aren't saved they will not show. Also if the theme/color of background/color of font is matching the drop down you will not see whats there. But as to not seeing the endings of the email address, that doesn't make any sense.

@Ale  spent a couple of hours researching on this, the best i could find for this question is this: https://productforums.google.com/forum/m/#!topic/gmail/tNbT7V0zLXs. Basically what this says is that your email information for your contacts are in the wrong fields. See if this will solve your problem, if it does I will edit my answer to reflect it.

How to view video/photo from smartphone to TV?
Is it possible to view media contents from the smartphone to the TV?
I would like to buy a movie from the PlayStore but I am not sure on how to view it.
I need a specific cable (to connect the HDMI port) or is possible to use chromecast too?

You didn't say what phone you have, or what Android version, so here's a summary.
Physical cables
If your phone supports MHL
and your TV does as well (almost all HDMI TVs do), then you can connect the phone to the TV with an MHL cable. There are two kinds of cables: a standard one, and a special one for certain kinds of Samsung phones. See How does MHL work? for more details. Usually, the TV mirrors the phone screen (i.e. it displays the same thing at the same resolution), but Android offers apps a way to display different content on the TV screen. This is commonly used by media players and presentation apps.
The oldest HDMI TVs don't support MHL, so you'll need a slightly different type of adaptor to connect your phone. You can tell these adaptors because they have an extra input for an external power supply (often a micro-USB socket). Apart from that, it works the same way.
If your phone supports SlimPort
Some phones use SlimPort instead of MHL, such as the Nexus 4. You can't tell by looking at the phone: both SlimPort and MHL use the USB-on-the-go connector. You have to know which one your phone uses. With the appropriate adaptor, you can connect your SlimPort phone to any HDMI, DisplayPort, or VGA input. Just like MHL, once you've done this the TV screen will mirror the phone screen, or some apps can display different content.
If your phone supports HDMI
A few phones and tablets have mini-HDMI or micro-HDMI outputs, but this has largely been replaced by MHL and SlimPort. If you do have one of these outputs, you'll need the appropriate cable to connect it to an HDMI input, and just like MHL or SlimPort, it'll mirror the phone screen, or display different content in apps that support it.
Chromecast
If you have a Chromecast and Android 4.4 or later
and your TV has HDMI input, then you can use that to mirror the phone screen on the TV wirelessly. Plug the Chromecast into your TV, and use the Chromecast app to help set it up. As with MHL, Android also offers apps a way to display different content on the TV screen.
If you have a Chromecast and earlier Android versions
You can still use Chromecast with media player apps that support it, including YouTube, Play Movies, and the Gallery on some devices. You just can't mirror the phone display to the TV.

I have Nexus4 not rooted with default kitkat 4.4.4

As I said, the Nexus 4 supports SlimPort, or you can use a Chromecast.

Greetings from SlimPort Support.  The way to connect your device to a TV or display is with a SlimPort HDMI adapter or dock.  There is a new product called the SlimPort NANO.CONSOLE that just launched on Indiegogo – it lets you connect your device to the big screen (at up to 4K Ultra HD 2160p video-out), simultaneously charge your device, and remotely control your device with the included Bluetooth Smart touchpad remote.  It’s really useful and plug-and-play easy to set up and use.  Please check it out on Indiegogo by searching on "NANO.CONSOLE".
You will also want to make sure your device is SlimPort supported.
Thank you!

Maximum number of devices an Android can handle from USB hub
We are planning to work with multiple USB devices from a tablet.
For this implementation, we are planning to connect a HUB (http://www.amazon.in/Belkin-F4U041SA-7-Ports-Hi-Speed-Powered/dp/B008368G72) to it via OTG.
My queries:

Will there be any issues in kernel device detection?
Will power be an bigger issue?

Also, request to suggest some more failures using this mechanism.

As it's a powered hub, power won't be a problem. Android doesn't have a specific limit on how many USB devices you can have, so the limit is that imposed by the USB specification. If I remember rightly, it's 256 devices, but you can check that for yourself if you're worried. Using a single USB hub with a device is well-tested on different kinds of devices.
The only other thing you need to check is that the tablet you're using supports USB-OTG. Most branded devices do these days, but cheaper tablets from unknown manufacturers, and older ones, don't. You also need Android 4.0.3 or later.

Where are IP addresses stored on Android?
Where are IP addresses stored on and Android device? In what location on disk, or otherwise; how are they stored?

IP addresses of what?

What's the actual problem you're trying to solve?

I want to store a persistent static IP address for my ethernet interface, to survive during reboot.

And what speaks against using the configuration menu? Doesn't that work, or doesn't it survice a reboot?

There is no static ip configuration choice in my prefs.

I have found the answer myself. At least for the device I am using here. All settings are stored in an Sqlite database as a file on the filesystem. Check out this thread on how to manipulate that database:
Is it safe to edit settings.db in Android

Under Settings, Wi-Fi, , Modify Network, Advanced Options, IP Settings, you should have a choice of Static or DHCP.  Choosing Static adds input boxes for IP address, Gateway, Network prefix, and DNS.
If you don't have this, I suggest trying a third-party app such as WiFi Manager.
Finally, if you're really talking about where in the filesystem this is stored, it's in /data/misc/wifi/ipconfig.txt, and is managed by the WifiConfigStore class. This is not a public API and is only used from class WifiStateMachine.  However, you can find out the format of this file by viewing the source: WifiConfigStore.java.

Good effort. However this seems device- or version-dependent because there is no files in my such directory.

Your original question doesn't include what version you're interested in, but if it did, I'd be happy to look into the specifics.  However, 2+ years after my answer, the latest Android Nougat on my device still has the above file (and others) in /data/misc/wifi/.  Note that if you don't have root access on your device, you cannot see, list, or access in any way, the files in /data and below, neither via shell nor file explorer apps. To an unprivileged shell or app, it will appear as though those folders and files don't exist, while in fact they do.

I am on Android 4.4.4 . I have root so I was able to expore the location, but couldn't find anything (text-readable, maybe binary?) there.

Hmm. I have a disadvantage of no longer having a physical 4.4.4 device to experiment with. I have only a Genymotion 4.4.4 VM which won't help since VMs are never connected to "real" WiFi, only virtual nets. They still have /data/misc/wifi but there's no config there except for wpa_supplicant.conf and softap.conf. This is expected, since the n/w config is "wired." In all the physical devices I currently have (5.1 and 7.0), the above directory contains ipconfig.txt, networkHistory.txt, and a bunch of other things.

The fact that you have an empty /data/misc/wifi leads me to believe that the vendor of your device may have customized this aspect of the device in some way. Having now looked back at the comment discussion on the original question, I suspect this is the case, since you stated you don't have the same menu items as everyone else seems to.  Note that the devices I'm working with are all stock Android.

If yes, flash the Stock ROM again and root the phone, intall CWM and install v2 zip file first and then v2.5.
I have been using Cosmic ROM v2.5 from the past one month and don't have any issues.

What are the effects of live wallpapers on battery consumption and speed?

7" tablet, Azpen A727, running Android 4.2.2

What is the effect of using live wallpapers on Android tablets?
I'm using a 7" tablet, running Jelly Bean 4.2.2 with a 1.5 GHz processor, 4GB flash memory, and I recently set my wallpaper to "Nexus" -- I want to know if this will have a negative effect on the (1) speed (2) battery life of my tablet.

possible duplicate of How much battery does using live wallpapers drain?

@bmdixon Good thought, but my question is about battery life AND speed, his is just about battery life. Thanks though :)

@bmdixon Although.....do you think I should rephrase the question to focus only on speed? ....that would remove all duplicacy, but would invalidate a large part of Dan's answer.

@geffchang I believe I missed the discussion....why was this question being considered for closure? ....because of the possible duplication?

It was suggested as duplicate of bmdixon's suggestion.

It depends on the live wallpaper in question, but in general, the wallpaper only runs when the home screen is visible. Since you're usually running an app or have the screen off, the live wallpaper has no effect most of the time: the extra battery use is limited to when you're looking at the home screen.
This isn't always true, though. Some live wallpapers also run extra things. For example, the live wallpaper might periodically run in the background so that it can change its appearance based on your email inbox, or weather reports from the internet, or the accelerometer. For that reason, some live wallpapers might use quite a lot of battery.
In that respect, live wallpapers are no different from any other app. If they're inefficient or do a lot of work, they'll run your battery down quickly. If they're efficient and simple, you won't notice any extra battery use. Unless reviewers comment on it, you won't know until you try.

Capturing LTE(?) voice packets with Shark for Root
I have a Samsung Galaxy Note 3 LTE. I installed Shark for Root but it only captures web traffic. I am assuming that LTE uses data to transmit calls as well (probably SIP) as everything is data these days, but it would be neat to see these packets and what they look like. Is there any way to do this?

No, calls don't work that way. They don't go through the same network interface as internet data, and they're treated completely differently by the modem. Phone networks are circuit-switched, not packet-switched like IP, so there aren't any "packets" to examine.

You're wrong, LTE does use IP packets for voice.

Stop android from automatically uploading images to dropbox and facebook
My wife has an Optimus LG. Every photo she takes automatically syncs with Dropbox and Facebook. I have looked but I can't see a way to stop this.
How can I stop this behavior?

For Dropbox, see How do I configure Dropbox in my Galaxy S III so that it does NOT automatically upload every photo/video I take?
For Facebook, see How can I disable automatic Facebook photo sync?
Of course, you can also just uninstall (or disable) either app to stop it uploading pictures.

Yeah, I guess we'll try to uninstall the apps and reinstall them. Both solutions have already been done according to my wife and I just confirmed that those settings are set to not sync.

Will my phone (carrier unlocked but initially locked to verizon) get locked after Kitkat update?
I've bought Motorola Droid Razr M from eBay. It is locked with Verizon by default, so seller unlocked device for me and it is working fine. It comes with Jelly bean 4.1.2 and I found that Kitkat update for this device. Now the question is Will my device get locked again after update from 4.1.2 to 4.4.2???

There's a 50-50 possibility of getting the phone locked because if the seller has unlocked through the proper way(legally) then you can go ahead and update your O.S else if your seller has unlocked by other means then definitely the phone will get locked to the Carrier with which it has the contract with(here Verizon).
I suggest you to get in contact with your device supplier and ask him his mode of unlock. An unlock never comes free of cost although some sites offer a legal unlock .The Same thing is what observed in other mobile OS(like ios) if you have unlocked it by other means and have updated your device then the phone gets locked to the carrier with which it was sold and you need to unlock it again.

I unlocked my HTC One by "other means" and had no problem with updating/rooting/ROMing, so I would expect the same for you.

Can i restore more than one msgstore.db.crypt7 file in whatsapp?

Recently changed my old phone to new one (Samsung to MotoX). During this old to new phone conversion phase (for one month) I didnt use Whatsapp at all.
Before totally stopped using whatsapp on my old phone, I Had taken whatsapp database backup from my old phone.
But when I got my new phone, in a hurry I totally forgot about whatsapp backup (which i had taken from old phone) and installed whatsapp on my new phone.
As per process it's got created new msgstore.db.crypt7 (just for that one month, during I didnt use whatsaap at all) file in database folder of whatsapp on my new phone.
Then I recollected about old whatsapp backup file (from old phone), so i uninstalled whatsapp on my new phone, again took a backup of newly created msgstore.db.crypt7 (from new phone), rename it as msgstorenew.db.crypt7 and kept in the same database folder of new phone.
To get all the older whatsapp message, i have kept old backup file msgstore.db.crypt7 (from old phone) in database folder of new phone and reinstalled whatsapp again on new phone.
I successfully able to restore all my old whatsapp messages.
But now along with the old whatsapp messages, I want to restore newly created whatsapp backup file (for one month) as well which i renamed it as msgstorenew.db.crypt7 (in the same database folder), so that i can have all the messages (old+new). But i am not able to find any option for the same.

Kindly help.
Thanks.

As you can read in the wahtsapp faq,

Current chat history will be lost upon restoration.

Anyway, you could follow these steps.
For every older conversation:
1)Use the "email conversation" function:

To export a copy of the history of an individual chat or group, you
  can use the Email Chat History feature:
Tap and hold on the conversation or group. Select Email conversation
  Choose whether to Attach Media or not. An email will be composed with
  your chat history attached as a .txt document.
If you choose to attach media, the most recent media sent will be
  added as attachments.

2) Send the composed email to yourself.
After you did that for every older chat, restore the newer ones using your backup.
This way:

You will be able to read your newer messages on whatsapp normally.
You will be able to read your older messages opening the attached .txt file in the emails that were composed

Nice answer. Welcome to Android enthusiasts

Install the latest version of WhatsApp from Google Play, then try restoring your backup. It fixed the issue for me.

How to download file using tasker?
I need to download files using tasker.(detailed post here on softwarerecs)
But I am not able to understand the HTTP_GET task. I want to download different files from various links read from a file, so I tried this settings.
Server:Port    http://

Everything else was optional so I left it as it is.
But I get Unknown host error. So I think I'm doing something wrong.
So can you give an example of downloading a file using tasker?

LOL OK, my comment must have been either too short or confusing :) // For context, the origin on our sister site: Android application to download pre defined files over WiFi automatically

Have a look at the Documentation (search for HTTP GET).
Server:Port    www.example.com:80

This is how you should format that request. The server is just the base of the url (www.example.com) and the Path is the path to the file in the respective server (path/to/file.txt).

I had read the documentation, but was getting it wrong. This solved the problem finally, Thanks!
BTW note that I had to add output filename so that the file actually gets saved, otherwise it was not getting saved.

@RegisteredUser I quote from the documentation: "Any returned data is stored in the variable %HTTPD if the content type is text-based (max 4K)". So if you just want to evaluate the response in some way, you don't need to save it to disk first.

Actually I would be downloading mostly packages for Linux(hundreds of them of small sizes(few  KB's or mb's) which totally make up to 1 or 2 GB)

How to unlock bootloader on samsung devices?
Before you try to install any custom ROM on your device, you need to unlock the phone’s bootloader, which is a code executed before any OS (operating system) launch. The notion of a bootloader is unanimous to all operating systems worldwide and includes systems running on your personal computers, laptops, tablets, smartphones, smartwatches and everything that has OS on it
HTC website has a section for developers where you can grab SDK; you just need to find your phone’s model. Samsung website does not offer such luxury, Sony Mobile website offers a section for users looking to unlock their Sony’s bootloader.

So, For Samsung Devices How to unlock Bootloader?
any useful reference links or comments or answers will much be appreciated :)

Note: am using Samsung note 3 neo

To unlock the boot loader you need to have the ADT with all the packages installed and configured.
Later once the configuration is done properly then you can connect your device and enable USB Debugging under the options.

Download Modaco’s Superboot files and save them to your computer.
Once downloaded, extract it by right clicking and extract all.
On your phone, click on Settings > Developer Options > Turn USB Debugging On.
Plug the device in to your computer via USB cable.
Open the superboot folder that we just extracted (until you see the folder with fastboot-windows inside it), then hold the shift key down on your computer and right click any blank area.
Now, select open command window here.
In the command prompt, type the following with hitting enter at the end of each line.

adb-windows reboot bootloader (and wait for the device to reboot)
fastboot-windows oem unlock
(If it gets stuck at waiting for device here, download and install PDANet on your computer, once installed, unplug then plug the device back in and see if that fixes it)
Once it runs the device should display a screen asking you if you
    are sure. Click yes using the volume buttons. The device will go
    back to the bootloader screen but say unlocked at the bottom.

ur welcome but before doing that please take up the backup if not done properly you will lose all the data

did you get this from xda ??

no the unlockr here's the link

does it applicable for normal Samsung device since the link saying that its for samsung galaxy nexus device

Samsung galaxy and nexus are completely different models whereas Galaxy is manufactured by Samsung and Nexus is manufactured by Lg but branded as Google. So it will work on your Samsung device also. Follow this link regarding nexus devices-http://en.wikipedia.org/wiki/Google_Nexus and this link regarding the galaxy devices-http://en.wikipedia.org/wiki/Samsung_Galaxy

will it work for Note 4 ?

@Dima yes it should and don't forget to download the respective android packages (i.e the android version of your device should be there in the ADT package installed in order to unlock and make sure you have a backup at handy just in case it goes haywire)

@user285oo6 10x, but what extra stuff do i need except the adt? i installed android sdk via brew, do i need to download anything else? btw, adb shell, adb pull all that stuff works fine with my note 4, does it mean this will work too?

as the adb shell works fine then you are good to go (usually adb shell requires the USB debug drivers to connect through which the device gets connected with the ADT).

doesnt work..  its stuck on 'waiting for device' in the fastboot

p.s. tried on mac and on windows, both without pdanet and with it

@Dima have  you enabled USB DEBUGGING in developer option ?

@WingedPanther yes

In my Samsung J3 (SM-J320M) the command "adb-windows reboot bootloader" restarts normally without going into bootloader mode.
And "fastboot-windows oem unlock" just waits forever.

which Modaco files?  Can you give a URL?

on samsung j5 2016, adb reboot bootloader goes into Odin Mode, downloading do not turn Off target ?!!! (I'm using linux but adb should have the same effect as adb-windows)

adb reboot bootloader (linux) reboots into the system

fastboot-windows oem unlock there is no fastboot with samsung gadgets

Change Cell Broadcast alarm
Lately whenever a missile is fired upon us, I receive cell broadcast alert about it.
In my area of living the city alarms are working loud anyway but the cell broadcast sound is extremely alerting and is over stressing my 3 years old kid.
I looked in the menu (Settings -> More -> Cell broadcasts) but and I found I can make it sound for only 2 seconds (instead of four).
I would like to keep the cell broadcast but change the tune. any ideas how can I do that?

Screenshot (click image for larger variant)

Possible settings/configuration is mentioned here - http://android.stackexchange.com/q/24039/35612
Might not cover your version of android but several different locations for the settings are mentioned in the answers. Reading most it seems to just toggle on/off, not actually configure?

So now it even reached the Negev, oy! More hints in other questions tagged cell-broadcast. B'hazlacha!

Polaris Office cannot set Date Format to UK
how can we change the input & displaying of dates in Polaris Office to UK format?
The devices are set in Settings/System/Date and Time/Select date format to UK style (dd/mm/yyyy).
The default within Polaris seems to be yyyy/mm/dd. Other android users wrongly think this is UK format.
You can change the date format of cells to be any of the following:

yyyy/mm/dd (default)
mm/dd/yyyy (US format)
mm/dd
dd-month-yy
dd-month
month-yy
month-yy
month dd, yyyy
dd month yyyy (almost UK format)

Ideally we need the correct UK date format dd/mm/yy or dd/mm/yyyy as this is already in our source files. We cannot change this (only the format of the cells) as users will be working on files generated from MySQL in MS Access and outputted to .xlsx
This seems an oversight on Polaris part, but I don't see much 'chatter' about it around the web, so should we notify Polaris of this?

Yes. If an app doesn't work the way you want, or you can't work out how to make it do what you want, it's always appropriate to contact the developer.
You can do this via Google Play: every app has to have an email address or phone number for support, which you can find on that app's page. Many apps also have a "support" or "feedback" option inside the app too.
Even if the answer is that there's no way to do this and they don't intend to add it, at least you know that from the horse's mouth, and of course if they get enough requests they may change their mind and add it. And going the other way, even if there was already a really simple way to do it, and they just tell you how to do it, it lets them know that they need to make it easier to find in future.

Thanks Dan, I've contacted Polaris and will post back here any response I get as an answer.

Nexus 4 screen goes blank while there is an incoming call
I am using Nexus 4 running on Kitkat 4.4.4 and facing a weird issue since a few days.

Whenever there is an incoming call, I can only hear the ringtone/vibrations but no display.
If I press the power button, I can not see the incoming call screen. So, I can not receive the call at all, even if I unlock the screen.
After this, if I try to call back, the outgoing call screen is not seen but the call goes through and I can continue with the call - but without the outgoing call screen. That means, I can not hang up the call if the phone is only ringing on the other side.
This behavior is random but frequent. After a reboot, everything comes back to normal.

Any way out to stop this? Any pointers would be helpful.

Exact solution for this issue was not found. This is not happening after I have updated my phone to Lollipop.

How to get rid of ad-ware
I've recently installed some games from Google Play Store. Then I uninstalled them all using application manager. The problem is now an advertisement popup appears now and then which stays on top for about 30 seconds and then a close button appears which lets me close it.
How can I get rid of this malware? device is a Samsung Galaxy Tab 3 8.0.

FYI, adverts of this nature are banned on Google Play, so if you find out which game was responsible, you should report it to Google.

Closely related: Is this red star icon malware? How to get rid of it? / Is there a reliable way to detect the app responsible for an Airpush ad?

Without a screen shot or a better description, we're only going to be able to guess at what you might have.

You can turn off your mobile data while playing the games. Settings > More Settings > Mobile Networks > Deselect "Mobile Data"
But with this, you can't sign in to Google Play Games service (if available in the game).

Root android lg ms690 version 2.2.1
Does anyone know how I can root my lg ms690. It is android version 2.2.1. Build # FRG83. Kernel version 2.6.32.9. SW version MS690ZV4. HW version 1.1. PRL verdion 3042. ERI version 1003. I have tried both zroot and gingerbreak, both with no success.

@bmdixon Please see the rooting tag-wiki, we do not close rooting questions towards that one since 1/2012 (oops!) – but instead permitting exactly one "how-do-I-root-my-X" question per device. The LG MS690 is not yet listed in our index, so I will add it now (you might wish to retract your close-vote ;)

Isn't the MS690 the same as the "LG Optimus M MS690" http://android.stackexchange.com/questions/19036/how-can-i-root-my-lg-optimus-m? From a quick search they appeared to be the same to me... Appologies if they're not the same.

towelroot by geohot claims to root pretty any version of Android. I didn't try it myself, but it's worth a try. Please report back when tried whether it was successful, so I make it an answer ;)

@bmdixon Ooops? In that case you're correct, but rather should link to that question with your VTC :) Found no "real proof", but GSMArena lists the M+ as "MS-695", which is a good indicator. // EVA: Can you confirm your device being the "Optimus M"?

I did wonder which one I should link to... Guess I picked the wrong one.

Have you tried using POOT? Download from Playstore and confirm if it supports your device. It works for most Android 2.x devices.

Backup data in recovery mode of LG
In the program LG PC Suite I used the option to recover upgrade errors. Now the phone (LG E975) is in Recovery mode. There are no options it only shows the following message:

Using this mode, service center can back up and recover your data.
  Press and hold the POWER key more than 8 seconds to reboot and
  continue using phone.

I searched after this software but it seems that only the LG service team has such one. I want to backup the data on my phone but I don't know what the LG PC Suite has already done.
How can I backup the data on the phone if I'm in Recovery mode?
EDIT:
Solved my problem with the LG PC Suite. I don't need the backup option in recovery mode anymore. I tried a few things, but none of them worked.

Is the device detected by ADB (i.e. running adb devices)?

Yes it is detected: `* daemon not running. starting it now on port 5037 *

daemon started successfully *
List of devices attached
LG-E975-45xxx321        recovery`

OK, before I make it a full-fledged answer with some more details, could you try running adb backup -f dummy.ab -noapk com.foobar (replacing com.foobar with the package name of an app you know is installed on the device)? That should backup the apps data. I never tried that from recovery, hence you've got to do that :)

It doesn't work because the dialog isn't shown on the screen. I get the message Now unlock your device and confirm the backup operation.

Yuck. Was afraid of something like that. OK, next variant: Backup and restore Android Settings and Application through ADB (I love our tag-wikis: take a look at the backup tag-wiki, I should have done that earlier ;)

I tried the adb pull command, DroidExplorer (don't find the sdk) and Simple ADB Backup. Nothing of them worked.
Do you have another idea?

Custom recovery? Then the last thing I can come up with is a Nandroid backup (single items can be extracted from that lateron). Stock recovery? No idea left at all. Sorry.

Preventing certain WAKELOCKS (NlpCollectorWakeLock, NlpWakeLock) with shell? (e.g. pm command)
As some of you might aware of, the notorious 'NlpCollectorWakeLock' and 'NlpWakeLock' are often the cause of considerable battery drain. I personally make some custom ROMs, and would like to automatically disable these without any app, but by a simple shell script. I tried disabling some activities by pm command, but no luck so far.
So can anyone give me some insight in disabling components/services/activities etc, that is related to these two wakelocks?
Thank you!

Not sure if you're in the right tracks with your attempt. Apps aquire wakelocks for a reason (well, at least that's the idea behind). Trouble is not them aquiring them, but those wakelocks sometimes not being released – which you cannot overcome by that. Your outcome would more likely be several apps/services stopping to work correctly, acting erraneously, or causing other errors.

If you're rooted, there's an Xposed module that you can use to throttle wakelocks: http://repo.xposed.info/module/com.ryansteckler.nlpunbounce

Understanding the Android boot
I really want to run pure Linux on my Android-based device (please, no chroot, etc. suggestions), and I want to fully understand how my device boots, from the bootloader as far as the init system. I'm not interested in any of the Android components that run after init.
I'm trying to dig into the recovery and boot partitions, without success. I figured out boot.img, but I can't open recovery.img.
What do you suggest me to read?
Also, I saw that there is a second kernel inside recovery.img. Is that right? If yes, what happens? When is the real kernel loaded?

Following up to the boot tag-wiki, you will find your answer here: Can somebody explain the boot process of an Android device?

I think I am familiar with these. Also everrything that happens after the init stage, is not of interest to me (all the strange java magic)

OK, but everything from your question going beyond that is rather off-topic here: this site is for end users and their issues with Android, not for development related issues (altering the RAM-disk and creating custom ROMs definitely belongs to the latter, per our definition). These things are much better discussed at sites like XDA, or other specialized developer forums. See also: Where can I ask questions that aren't Android Enthusiast questions? Good luck!

Android tablet not auto-updating applications
I have an android tablet that is leveraging an internal company network. It appears that this device and all others similar to it are not auto-updating applications from the Play Store even though all the appropriate settings are correct.
I can see there are apps to update and I can even manually update an app but the auto-update never runs for any apps.
The same tablet in my home network will run the auto-update.
Could the companies internal network somehow be blocking the auto-update? If so how does the auto-update work so I can add exceptions to the firewall.
UPDATE
This device is a HP Slate 21 Pro All-In One and has both a WiFi and an Ethernet (wired) connection. We found that when the device is connected on the company network using a WiFi connection it DOES auto-update but it DOES NOT when connected using the ethernet connection.
My guess is that the Playstore (GMS) is checking if there is a WiFi connection and if so downloading the updates and if not a WiFi connection it does not download the updates. Similar to how a true mobile device behaves where there is either a wifi or cellular network connection.

Can you update manually? Do you get update notifications?

Yes, I can view my installed apps from the play store and it lists all those that have updates. I can then manually update them.

I didn't mean to manually check, but whether it retrieves update information automatically. What I'm after is possibly ruling out (or not) your company network blocking the port required by GCM (Google Cloud Messaging) to retrieve incoming information. To cross-check (and rule out it's that specific device/installation): Taking that tablet to your home network, does it work then there?

It am guessing it is retrieving the update information as when I view My Apps in the Google Playstore it states there is an update available, and yes the tablet works from my home network.

Could it be you disabled notifications for the playstore app? But that wouldn't explain the very same device working at home. I'm not sure how exactly it works, but it might well be for "passive notifications" (without the user triggering anything by e.g. opening the app), a separate specific port is being used (which might be blocked in the "corporate firewall").

Apparently this is a known issue and HP is aware of this. At this moment there is no fix for this issue.

This issue has been reported to HP and has been confirmed it is an issue on their end or with the Play Store software.

Can't get file to copy from /sys/ on rooted Android
I'm currently rooted  on a Samsung S3 i9300 running a custom rom on Kitkat 4.4.2
I use es file explorer to perform root tasks on directories and files, I wanted to permanently turn off the led lights on my phone's hardware softkeys as I don't use them anymore.
I read somewhere on xda developers that changing the numeric string 255 in the max_brightness file to 0
in /sys/class/leds/mmc1:: and
/sys/class/leds/mmc2::  should do the trick.
I have "root explorer" on in Es file explorer and have the right permissions to copy the file over to my SD card but I kept getting a task failed error in the app.
I then decided to go hardcore by using the terminal emulator app from the play store using the Linux command line syntax.
I was able to copy the file over to my SD card but something strange happened, the original file according to es file explorer was 4kb in size while the file copied to the SD card was 2 bytes in size..
I'm really puzzled, is there a better way to copy files from the root directories?
PS: The "mmc1::" and "mmc2::" folder icon has an arrow shortcut icon next to it and I've always been able to copy other files from root directories using es file explorer until this particular file.

Files in /sys/ are part of sysfs which is a special virtual filesystem to dialog with the Linux kernel.
You can for example have a fast introduction here.
Therefore you cannot treat sysfs files as normal files as it may lead to strange behaviour depending on how the program treats them (same for device files, usually in /dev, or files in procfs in /proc).
Usually to tweak that files you just write in them with an echo, such as
echo 255 > /sys/class/leds/mmc1::/max_brightness

Oh wow.. Thank you so much.. So if I wanted to change 255 to 0 .. I would have to echo in 0 instead of 255 right?

yep just "echo 0 > /sys/class/.....". be aware that this setting will get back to original value after a reboot. if you want to make it permanent you should put the echo in some boot script. to read the value just use "cat /sys/class/......"

Oh. And do you have a resource where I can learn how to create a boot script?

No text message notifications on Android 4.4.2
I just upgraded my Note 2 with 4.4.2, and since then I stop receiving notifications from text messages, voice mails and emails. I do not see the LED blinking on any text messages or voice messages.
Everything is active in my LED indicator, everything in my "messagings notification settings" is enable, all my volume are at 100%
What can I do to fix thiS?

For your SMS:
Check if the notifications in "messaging" is turned off. Maybe you, someone or an app turned it off (untrusted app). Turn on the app and make sure the "show notifications" is checked.
Go to: Settings -> More -> Application Manager -> All -> Messaging
You can do the same process for emails and voice messages.
Now, make sure all the services are ON for emails and voice messages.
Go to: Settings -> More -> Application Manager -> Turned off
Check if any emails or voice services are off. If these are off (you prob have rooted your phone) then you should be able to turn them back on.
You might need to reboot for these.

sorry but I have to ask, did you restarted your phone and checked if that fixes the problem, if so then go to System Settings->Notifications and check there if everything is set there.

I did reboot but I can't find "System Settings->Notifications". I checked in my sounds and led and everything is checked.

did you switch to hangouts? also try to check setting->apps->messaging options there

I cant find this option ... is it under connection? my device? accounts? or more?

I think after the update it will be under more and it's called application manager, but make sure you are not using hangouts as default sms app

Two ideas.
From your home screen, go to Settings, then choose Sounds, then choose Volume then look at the slider for Notifications.  If it's all the way to the left, then your notification volume is off, slide it to the right and that might fix the problem
Also, I was told that there was a problem in the 4.4.2 build and only the "whistle" sound works.
Last, Go to settings. then choose sounds, then look for the banner that reads, "Samsung Applications"  there are 4 choices under it.  (Call Messaging Email Calendar) Pick Messaging.  Make sure Notifications is checked.  Select Ringtone must be "default ringtone".
Michael

Go to Settings -> Apps  -> All (scroll horizontally), search for Messaging, and check Show Notifications.

I just had this issue on my Google Pixel 3XL. Click on "Shortcut to Prevent Ringing" and turn it off.
All of my sounds started working after that.

Try going to
sounds and notifications >
Application notifications >
Messages >
Unblock

You could as well uninstall your phone launcher.
Most of these launchers might interfere with your app notifications by listing them as junk.
All the best.

How did you come to this conclusion? It is hard to establish a relation between the problem and the suggested solution here, not to mention, removing the only launcher can render the phone useless to OP and frighten them.

How to tell if you are part of a group text message
When being texted by another Android user, is there some way to determine whether you are part of a group text or being contacted individually?

Sometimes, when I send the same text to multiple people, if they are in a group chat on their iPhone and add me, then I can see who is texting who (or at least the numbers of the people). If I'm holding a group chat in Google Hangouts I can see the people as well. Otherwise.... There is not way to tell.

Only way I found is by holding down on message and clicking DETAILS then it shows the list of people message went to.  Another giveaway is if the message says REPLY ALL.

Press and hold the text message you received.
A menu will come up with view details at the bottom of the list.
Press on view details, it will show you everything about the text.

What happens to Crash Reports sent to Google?
Many Android applications have bugs. These include app crashing, screen flickers or failing to start altogether.
The app crashes present the well-known Unfortunately, **AppName** has stopped screen.

But sometimes actually pressing the left button and sending the report seems like a bit of a waste of time since I never get to know what happened to the report.
What does actually happen once this report is sent? Is it known what Google does with it? Does Google pass them on to the developers of the app that crashed? And do we how many crash reports Google receives per day?

Actually, I think Google won't diagnose those crashes for individual Apps, instead they only collect those reports and present to the developers responsible for the App, and it's their business to trouble shoot the problems. Please check the official document as below.

Photos copied via bluetooth from LG 4X HD to Xperia Z are no longer sorted
I recently copied all my photos and videos from my LG to my Xperia Z using Bluetooth. It took a while but the all copied over fine and are in  a single album, My Album, under a folder named Bluetooth.
The problem is that they are now unsorted. On the LG phone, I had all of the media files organized by different albums but now they are all in a single album.
Is there a way to copy these using Bluetooth or another method without losing the album structure and naming?

It seems you have lost your folder structure ("albums") due to the Bluetooth transfer. A possible solution would be to copy not over Bluetooth but rather with a Computer (USB) or over Wifi and a network share, to retain the folder structure.
There are many file managers available in the play store which can use network shares. You may also consider using DropBox or that kind of service.

If both the devices have NFC then try that or else as @Markus has said you can only do is transfer only through the USB cable. USB cable is a better option for faster data transfer and the best part it retains the file structure in the way it was stored on another device.
For that first you need to store the file as it is on the System later connect your xperia and transfer the same file .
USB transfer is best for moving files >10MB (more then 5-6 photos) to reduce time whereas NFC is best for single or couple of photos

Delete folders from the SD storage
I have a Nexus 4 smartphone and in external storage there are many folders which I believe to be unused and/or empty.
Is it possible to delete them safely? In other words, if I delete an empty folder that is really needed by an app, will it get recreated automatically or will I break the app?

If they are empty, they can be deleted. They will be recreated as needed. Before deleting them, make sure that they really are empty. As in, not even hidden files are there, except for ones like ".nomedia"

Removing empty folders may not account for much space, but the following will help you remove them.
Install "SD Maid" from the Playstore then run 'SystemCleaner' from within.
To remove junk files install "Clean Master" then click on  'Junk Files', cache files  and APK files may use up a significant amount of space.   Faster here than clearing cache files for each application and it is not just browsers that have old cache files.

Install app without touchscreen or ADB?
My phones digitizer seems to have gone bad (after 5hrs of few app updates and 3hrs of a fall, working twice after that for 10minutes). It doesn't seems that the USB Debugging option is enabled on the phone, due to which I can't access phone using ADB.
I intend to install a VNC server app on my phone and use it to control the phone through my Laptop. Then try and isolate the apps to rule out if the apps caused the issue.
Is it possible to install an app in my case**?**
There are no passwords or screen locks set. Also just the power and volume buttons are working. I can go to Fasboot & Recovery mode but can't select any option. :(
Please note: No data connection is turned on. So I can't install any remote app using Google Play store.

Which phone do you have?

Micromax A116 with Android 4.1.x

This link has commands to connect but it uses Linux with installed uudecode. I have Win7. http://android.stackexchange.com/questions/12834/broken-screen-while-debug-mode-was-disabled-how-can-i-re-enable-adb

Check if you can connect a mouse (or Keyboard) through USB OTG port (and microUSB-to-USB converter cable)...
I'm not sure whether your device supports OTG or not... Just give a try...

(Also, a keyboard if you really don't have an USB mouse around)

@domen Yeah. That's right!

Yes, if the phone is connected to the internet, you can install apps from the Google Play web interface](https://play.google.com/store/apps) without touching the phone.
Starting the app is a different matter, though: you may need to find an app that's specifically designed for this situation, so it can be triggered without needing to open it from the launcher, or use a USB gamepad (or a Bluetooth one, if it's already paired) to control the launcher without using the touchscreen.

No data connection ON. :( Or I would have installed VNC server app till now and gotten out of this mess.

@Jay You need to add this information to your question.

Sorry, my bad...

Try with shell using a keyboard
pm install [path_to_apk]

So how do you get a shell in the first place without the touchscreen or ADB?

What device do you have?

And what does "does not boot properly" mean? What actually happens?

Possible with command but there are conditions,

you have usb debugging enabled
you need to configure adb

if you have this two things configured then you can type following command to boot your phone into recovery mode
adb reboot recovery

or

Files and Data loss when sd card is changed from java supported phone to android phone
I have changed my micro sd card from Samsung Star2 S5263 which is running on Java OS to a new android phone. Later I have connected my android phone to my PC to copy some files from the system.
And after copying, I have placed my sd card into my old phone (Samsung Star2 S5263) only to find some of the files, images and videos are missing. When I tried to open those, it says invalid file format.
Files which were absolutely fine a few minutes ago, now says invalid file format. When I have connected to the system, I haven't touched these files. Any reason why this happens? How to get the files back? (Those images are absolutely important!!)
Thanks

If you removed the micro SD card from a device (any device) while it was still in use, this can cause filesystem corruption. This can often be repaired by connecting it to a card reader on your PC and using a disk scanning tool (e.g. ScanDisk on Windows).

Anyone knows how to fix this issue?

How move applications from built-in memory to SD-card without root access?
I have Sony Xperia M.
It has 4GB of built-in memory, however I see only 2GB)))
The fact of applications can be installed only in built-in memory upset me very much.
I do not play any hard games. Heavy one, I've installed, is 150MB program of off-line maps with 3 city and it occupies all of place((( Now I have a 16GB of free place on my SD-card and I get a message every minute, that it is not enough memory for android. It is very sad news.
I have moved or deleted from built-in memory everything I can.
Can I explain to my phone that sd-memory is exactly the same memory as a built-in?
Or somehow can I move one my heavy application to sd-card, keep it works?
Or what do you advice me with this?
Thank you in advance.

I've just added two tags to your questions. Please check the insufficient-memory tag-wiki plus the app2sd tag-wiki, they hold the information you need to get started on this. Then please return and answer your own question if solved, or [edit] it and describe what you've tried and were you're stuck. Thanks!

All programs in the links, you gave me, need a root access. I want avoid it very much. So I started to brake. It is very sad, but manufacturer does not leave me any choice. Thanks.

The tag-wikis themselves give outlines, and in the case of app2sd explain the basic ideas. Have you checked e.g. the questions tagged app2sd for possible non-root solutions? I know they do exist, question is just which of them works with your device. See e.g. this answer (newer syntax), Move App to SD in Jelly Bean.

Why chrome shows video in android device, but opera does not?
Opera has built-in proxy and presser of traffic - it is very useful for me. But opera, instead of to show a video, downloads it. It isn't I want.
How can I (without root and with android 4.3) learn opera to show a video as well as chrome does?

Maybe the video you're trying to view requires a HTML5 player? I've heard Opera doesn't support those.

No, it is flash. Android from 4.1 do not support flash player officially, I hear. But somehow chrome ignore it. The second fact is Opera is exactly the same chrome, because it use a chromium. I think there is a solution must be somewhere(((

If you disable the Off-road mode in Opera then it plays the video rather than downloading it.

My opera is non-English, what do you mean "off-road mode"? "Pressing mode" needs me as proxy to get a site, where I want to see a video. Nothing passerby to "off-road" in options I did not find.

Thank you. I handle it. So "off-road mode" translated as "pressing mode". First it must be turned on to surf a site, next it must be turned off and open video in private tab.
