Will Security apps work even after flashing new rom?
Assume that I have turned on Android Device manager to locate my phone in case of theft,  and I also installed some security apps which can send message when someone tries to change the SIM card.
Now suppose I lost my phone. The one who finds it is tech savvy. Firstly, (s)he does a factory reset after booting into Recovery mode, followed by flashing a new custom ROM, and then (s)he starts using my phone.
Will Android Device Manager still  work?

The Android Device Manager will probably still work, provided the new ROM contains the GApps. But it won't listen to you any longer.
If, as you describe in your question, the "new holder" is from the tech field, and did a thorough wipe plus installs a new ROM, nothing from your installation survives. It simply can't, with really all storage wiped/overwritten.
What some of those security apps offer is to be integrated with the ROM (on rooted devices only, of course). That helps to survice a factory-reset, as that doesn't touch the ROM (or, more precisely: /system, where those apps are installed then). But with the entire ROM and recovery replaced, plus all data wiped, where should they "stay"?

stolen Galaxy tab 4. can it be located
My Galaxy tab 4 has been stolen, it has a password on it but I know this is possible to bypass by factory reset. If the person has done this is it possible to still locate. Has it got an internal serial number which maybe Samsung could locate.

Have you tried to locate/lock using Android Device Manager?

If the device has been factory reset, you won't be able to locate it using Android Device Manager. You could try asking Samsung but I doubt they can do this, especially on a device without data.

Does using various app stores in parallel cause any issues?
I am using a Android phone with Lollipop and found that apps can be installed from various app stores like Google Play, Amazon App Store or F-Droid.
Are there any problems I can run into if apps are installed from different app stores?

You may want to have to look at this post.

Depends on the store you're using, and how safe it is. See e.g. our alternative-markets tag-wiki, questions using that tag, and especially How safe is it to use Aptoide?
I've made pretty good experiences with F-Droid, and also with Aptoide (sticking to their main repository named "Apps", which is curated manually and well maintained – see the link in previous paragraph). Close to no side-effects as far as I can tell. Only issue with F-Droid is a two-fold: they build the apps themselves from the sources, so they need to sign using their own keys; while that makes sure you really get what it says (the .apk is sure to match the sources you can investigate), you cannot "cross-update" apps from them with other app stores (e.g. install from F-Droid and then update from Google/Aptoide doesn't work due to signature mismatch).
I cannot speak for other markets, as I don't use them. One specific thing to consider are payed apps, for at least two reasons: 1) that most likely demands the market's app to be running on your device (for license verification) – and 2) if that market "shuts down", you will either have to buy the apps again from another place or no longer receive updates (which e.g. happened with AndroidPIT's app-center on 2014-12-31).

Like Izzy said, the security of the app store is very important. In addition, make sure not to download the same app, or an app with the same package name on two different markets, it might create a conflict and produce a few errors, possibly a signature mismatch but it may vary by market. If the creators of the market are smart, they would prevent the error by not allowing the user to download the app again, if they already have an app under the same package-name. Amazon and 1Market both prevent this issue. I am not sure about the other markets.

How can I hide phone number during incoming call and display only contact name?
I wish to show only contact name during incoming call, for some privacy reasons I wish to hide numbers and display only contact name.
I won't usually pick up anonymous calls, is there any option to achieve this?
Android version 4.4 and without root option is preferable.

You can also try using Lollipop Call Free which shows only the Contact name and its same as the Lollipop style calling screen and theme which you can customize the way to want to.

It seems that there is no out-of-the-box way to achieve this. Maybe knowing the device that you're using will help (by editing your question, or commenting on it), but I doubt that.
That being said, You can achieve your goal with an app, like Full Screen Caller ID. In there, at Settings->Display there are check boxes for Display phone number and Display name.
Personally, I wasn't too impressed with this app, but it does what you wanted.

Seeking for an alternative to lock the screen without pressing the power button in Lollipop
I find it cumbersome to press the power button on my Android Lollipop device for locking the screen.
Are there alternatives (like a widget or a gesture) that use some interaction with the touch screen to get the device locked, apart from the automatic lock after timeout?
Also, is there any possibility to lock the screen without the need to install an app?

Is the device rooted? Which Android launcher are you using?

Well, if you have Terminal Emulator or Tasker installed then an easy solution can be provided which would require no installation of an app.

Double tap the  status bar should work ... Try it

@LôrdRalfAdolf Yeah, good finding! But that's kernel specific feature and unless OEM provided that option under "Settings" and user enabled it, that double tapping wouldn't work.

@firelord the asker wants a methode without installing any third party apps so that's all I got ,It worth a try isn't it ?

@LôrdRalfAdolf Easy! I actually agreed (voted the comment), and also said "good finding!" as an appreciation. I just had to mention the reality and I still would say that your suggestion is the best available on this page as of now, provided that the feature is enabled of course. :)

@Firelord thanks for the clarification ,I will think of something else there is a lot of tweaks to do that like sweep2sleep (can be added at the kernel level) but I can't think of a stock method to do it ,I will be back with a solution ASAP ,thanks once again

Try Screen Off and Lock and Screen Lock app from the playstore. You don't need to press the power button or wait for timeout to lock the screen. Just press the icon and it will lock the screen. You can customize the sounds and animation in which an animation plays before locking the screen.

Is there any possibility to lock the screen without the need to install an app?

AFAIK no there is no way to do that in Stock Android.

Thank you for your hints! I finally installed Lock Screen app from F-Droid Store and use it from the home screen dock now.

Monitor Outbound Connections
I just got a new LG G4, and connected it to my office wifi.
The network IT guy asked what I had running on my phone because it was making a lot of network connection calls.
He said he saw 3 in about a minute in his log, which was abnormal.
So I'm looking for something similar to this: Looking for a network monitor that can enumerate outbound connections , but without needing root.
I'm a little worried that it may be using mobile data without me knowing, and would like to stay on top of it.

Which Android version are you using? You can try OS Monitor to show active connections, and NoRoot Firewall which will show notifications/logs based on app request to connections (run it in all blacklist mode, and allow each app one by one and notice which one is the cause of abnormal behavior; or try your own technique).

See related answers here and here, also here – basically saying what @Firelord already wrote, but giving some more details: OS Monitor is your choice here.

Most android devices now have monitors built within their software. I'm not familiar with the G4 so I can't say for certain it has the feature but my Samsung S5 does so I can lead you to it based off of that.
If you go to Settings there may be an item labeled "Data Usage". If not, look for "Mobile Data" and see if its in there. Within there it will show what apps are using data and how much data they're using. It's a great way to monitor your device.

I would like to know how your answer addresses "He said he saw 3 in about a minute in his log, which was abnormal."

I am looking for something a little more fine grained. The Data monitor shows large data usage, but not necessarily frequent small usage.

Does Android OS clutter similar to Desktop OS
What I mean by this. Is it expected that overtime, the performance of a device will be reduced, and the software will work slower? This is assuming no changes in core OS (e.g upgrade from 4 to 5 etc). For example, does installing and removing apps leave  traces behind, that over time build up and slow the OS?
Is there any indication that a user can look for, in order to determine if its time to flash the device, and re-install the OS?
p.s Lets ignore the scenario where a bunch user installed process-hog- background apps are killing the device.

Note: "re-install the OS" won't be required, as that resides on a read-only partition. Still, a factory-reset sometimes does wonders (but you should backup your stuff before, so you can restore it afterwards).

"..clutter similar to Desktop OS" -- Using Slackware Linux here for 16 months, don't know what clutter really mean unless you meant "Desktop" as "Windows". As for the indication part, you can tell by your experience as a user of device by comparing your first impression of device and your present one.

@Firelord not very helpful comment tho, because it is hard to remember first impressions of device.

Simple answer: Yes, but it's usually not noticeable and won't impact a device's ability to function as expected during it's lifetime.
Full Explanation: Apps CAN leave traces of information behind when uninstalled. These are usually empty folder and misc. log files, but can also include files created by the application but are assumed that the user would want to keep (screenshot folders come to mind). Although these hardly affect performance, they can eventually take up space and introduce unwanted clutter in your mounted storage volume. Purge with aplomb.
Another area of possible concern is the concept of "bit-rot", or "bit-decay". This is the decay of data stored in a solid-state format, unaltered, for long periods of time due to the dispersion of the electric charge used to maintain the data. An OS of a phone could be subject to this phenomenon over the course of many years (usually more than a decade) because the data of an OS rarely changes in the scenario you present (not updating and never re-installing). Though reinstall the OS will refresh the memory locations it's stored on, the process of bit-rot takes a long time on properly manufactured devices, and isn't likely to cause any sort of problems in the 2-3 year timeframe most individuals keep their phones and tablets nowadays.

YouTube not showing the names of the videos searched unless video is clicked, neither can be skipped to a certain time
I'm using a tablet, and the problem is that YouTube is not showing the name of the videos I've searched unless I click the video.
Also, whenever I watch a video I can't skip it to a certain time (the red bar in the bottom where you can skip the video to the end is missing for my YouTube).
What should I do to resolve this issue?

Could you provide the screenshot, and also the device model and the Android version?

There are two ways to resolve this.
1. Reboot your device
2. Your youtube app is outdated so one thing you could do is upddate the app

How to fix hanging Samsung Galaxy S II phone (GT-I9100)? Also flash and root it?
I have a Samsung Galaxy S II model smartphone. GT-I9100 is the exact model number 1, mentioning it since I saw here:
https://en.wikipedia.org/wiki/Samsung_Galaxy_S_II
that there are variants with slightly different model numbers (such as GT-I9100G) and correspondingly slightly different hardware features.
1 That exact model number (GT-I9100) shows both while it boots up, and also when you go to Settings -> About Phone.
(Sorry for the slightly long question, but I have tried to make it as clear as possible.)
A while ago it suddenly stopped booting properly. Before that it was working fine for over 2 years. I had bought it used; not sure if that has anything to do with the problem, but after I first bought it, it almost never had any problem for those 2 or so years, except for one issue: it sometimes used to shut down automatically, without my doing anything. But powering it on again, always resulted in it working normally again. I asked the dealer from whom I bought it, about this issue, and he said it was a known issue in that model.
Now, whenever I power it on, it only goes up to the initial Samsung splash screen (with a big stylized S in the middle of the screen), with the model number GT-I9100 on the right side of the screen, then only the big S for a bit, then again the big S with the words "Samsung Galaxy S II" below it [2], then hangs at the point, indefinitely. Also, while in this hung state (which can only be stopped by removing the battery), it intermittently a) flashes the big S a little brighter, and then b) makes two short beeps. Events a) and b) keep repeating at intervals, of maybe a minute or two. The phone also gets a little heated, maybe due to the big S getting brighter (and then dimmer).
[2] Image of phone in that state is at bottom of this post.
I would like to know how to do the following:

Fix it so that it boots fully and works normally. I would like to preserve the data on it, such as contacts, etc., but in the worst case, I'm okay with losing all the data, as long as I can get the phone working again. (I have an older Samsung Android phone which I using as of now, and I had saved most of my important contacts in my Google account, not in the phone or SIM.)
I would like to know how to flash and root it, maybe with CyanogenMod or a similar OS. I heard from a friend that by doing that, the battery charge lasts for longer, due to no unwanted apps or services running, apart from the fact that a flashed and rooted phone can be used for more things, such as sshing into a server where I have an account, or getting a Linux console on the phone (which would be cool and useful, even if I could only run a subset of Linux commands).

I will search the net for steps for flashing and rooting it, but would like to know if anyone has any general guidelines for that.
If I need to give any more information for any one to suggest solutions, please let me know.
Thanks.

OK, so for question #1
Try to get into recovery mode and then wipe cache partition and dalvik cache - that should help. As I remember, stock recovery is capable of doing that kind of basic things (if I'm wrong - correct me).
Basically, you can get to recovery by holding volume down and power button while your phone is off, then release the power button but hold the other one. That should work, if not - check YouTube, I bet guys got the video about how it works with your device.

UPDATE

As for second question, I don't really see a point of flashing CM or something similar cause it somehow buggy. My buddie at university has got the same device as you and after all the geeky flashing stuff he decided to go along with rooted stock.

In order to root your device - again YouTube or XDA should help you ;)

Thanks dnomad, will try out your suggestions and then reply here again on the results. I should have mentioned that I know Linux well as a user and some as a sysadmin (though not done that for a while), so if anyone has any suggestions that involve Unix knowledge, including connecting to the phone from a PC running Linux via a cable to do any troubleshooting (I realize it will have to be after the phone can boot again), please feel free to give such suggestions.

Well, that makes things a bit easier though. Firstly, check if you have android-tools-adb and android-tools-fastboot installed. The way to check this is obviously depends on your package manager, in case of debian derivatives with apt-get as Ubuntu: sudo apt-get install android-tools-adb android-tools-fastboot. Then connect your device to computer after getting in recovery. From that point you can use some diagnosis tools with adb/fastboot. Anyway, firstly you should try to clear cache as I mentioned before.

Use Bluetooth Headphones with Phone and Old Laptop
I am wondering if there is a way for me to play audio that is coming into the headphone jack on my phone out of my phone's bluetooth. I have bluetooth headphones that do not work with my old laptop but I could easily plug a male-male headphone cable from my computer into my phone. If I did this is there a way to make the sound coming out of my laptop be played over my phone's bluetooth?
Alternative solutions are also encouraged, however I thought this one was the most plausible.

The solution that I used was to plug the male-male headphone cable mentioned in my question from my laptop speaker output into my microphone input jack of the same type. Then I ran an internet radio server program from the laptop on my LAN. The radio program played sound that was coming in from the microphone jack which was just the output of the speaker/headphone jack; in other words, I was playing the output of my speakers through the internet radio server. Then I played the sound out of my phone with an internet radio p
Works like a charm, though there is a slight (3 second) delay in the sound due to the internet radio server, but I would recommend doing it this way for anyone who needs to play sound out of their non-bluetooth enabled computer through bluetooth headphones if they have access to an Android phone.

I am not sure this will exactly fulfil your requirements. But i think USB Bluetooth Adapter Dongle would enable Bluetooth connectivity to your old laptop and you can play directly via laptop.
When you have easy access to your Bluetooth headphone from mobile then why don't you transfer audio files into your phone :-)
What I have understood from your question is :

I would rather not purchase a bluetooth dongle. And I cannot just play it from my phone because it's not just audio files but sounds from web apps and other things that have to be from my computer.

How can I increase the transmission power of Wi-Fi in Redmi 1S running Kitkat?
I am using a Redmi 1S mobile running MIUI 6 on KitKat. The mobile is rooted.
Is there any way to increase the Wi-Fi transmission power of my mobile?
Things I've tried:

I have tried using iwconfig in terminal emulator.
I have tried WiFi tx power app from play store.
Both of these didn't work for me.

Usually the tx power is already at the maximum value. Even iwconfig won't be able to increase it, it would have already increased it, if it wasn't at the maximum value.

@GiantTree I tried decreasing the power but that too didn't work.

not able to recieve incoming calls
Myy phone model is HTC desire 526 g plus.when I rang called it from another phone  in showed ring is going but on the phone message appeared,"Unfortunately the process com.android.phone has stopped. Very confused. I remember I installed an app call name announcer. First it worked but after few minutes this problem has risen.NEED UR HELP pls do reply

The inbuilt app named "Phone" has the name com.android.phone. I don't know what's causing the crash but you may try "Settings -> Apps -> All apps -> Phone -> Clear Data -> Clear Cache".

If the call name announcer did in fact cause a crash, try removing that app first, and have someone call you again. If it is still crashing, follow @Firelord's advice, clear the data and cache of the phone app, and perhaps try turning the phone off and on again.
Lastly, if you are STILL getting this problem, try doing a factory reset. If THAT doesn't fix the problem, go back to wherever you got the phone and ask for a new one.

Android M Auto Backup with multiple devices
https://developer.android.com/preview/backup/index.html
How does the new Android M Auto Backup feature work when you have multiple devices using the same Google Account (e.g. phone and tablet)? Does it keep separate per-device backups if you have the same app installed on multiple devices? If so, when the app is installed on a new device, how does it know which backup to restore?
The link above doesn't address this at all.

I can't speak to how it stores the backup data, but as for knowing which to restore, it should follow the same system as Lollipop: when you setup a new device, it actively shows you a list of your previous devices, and when they were last used, so you can choose which one to restore from, and even lets you deselect the apps you don't wish to restore.

Easiest way to resize and email pictures?
I have some clients that need to take high quality photos with their cell phones, send the photos via email, but keep the original size for later. (don't ask :P )
I'm looking for the easiest way to resize a bunch of pictures and email them, without modifying the original photo.
I guess ideally there would be a setting in the mail app that could downsize all the photos, but I don't see that in any Android mail apps. Another ideal thing would be an Android app like Instasize that could resize multiple photos and then email them. I can't find one.
Anyway, what's the most efficient way to resize 10-30 photos and email them?
Thanks!

You need to modify the original photo for resizing it. By resizing do you mean to compress the pictures? Are you facing and problems with the app Instasize that you mentioned?

Sure, compressing would work (can you even compress jpegs though?)
Instasize does one photo at a time, I was hoping for something that resizes/shrinks a bunch of pictures at once

Android doesn't have such a feature built-in. But there are several apps available a.o. at Google Play which can help you out (for a list, see Other photo editors on my site). One of those is JustResizeIt!, which also offers batch-resizing:

JustResizeIt! mobile free lets you resize and share your pictures with all your friends and family with only a few taps.
It can send entire albums via email to many recipients, add resized photos to your online gallery, upload original images to a FTP/FTPS server or create new albums.

Its feature list explicitly names:

send many pictures to many recipients with only a few taps
create a reusable widget for each purpose
resize pictures to any desired resolution
resize as much pictures as you want

So this should perfectly match your needs.

Block specific cookies?
Some sites use cookies to annoy users in various ways (i.e. by nagging return visitors). Is there a way to block specific sites from using cookies in Chrome without disabling cookies globally? I know this is possible on the desktop, but I cannot figure out how to do it on Android.

Have you tried this (for Chrome Beta, says to go to Settings to control cookie behavior per site), or this answer by Google?

Yes, that allows disabling cookies globally, but not per site. I want to block e.g. *.example.com from setting cookies. I saw the answer, but something must have changed in Lollipop, because I cannot access the settings that way.

Replacing L-style soft buttons with KitKat-style soft buttons?
I'd like to upgrade my Nexus 5 from CM11 (based on Android 4.4.2) to CM12 (based on Android 5), but I can't stand the new ultra-minimalist soft button icons of Android L.
I find myself constantly forgetting which is which (why is Home a circle?) and just don't like their visual appearance.
Is there any way to replace the Android L soft button icon set with the Android K soft button icon set?

I thought GravityBox could help but it didn't. May be you can find this answer useful, if not satisfactory to the goal.

There is this SoftkeyZ Root which claims to change those soft-key icons, or try this article which mentions XDA threads having soft-keys collections.

How to turn on HTC One Mini with a broken power button?
My power button is broken, and unfortunately you cannot take the battery out to turn it on like I seen in youtube tutorials, therefore Im seeking for anyones help to tell me how to turn it on? I also tried the volume keys; don't work...
Thanks

Unfortunately adb wont help if the phone is switched off completely. Did you try plugging it in charger or connecting to pc?

I guess there's no other way than opening the case and manually shorting out power button pins for 1 - 2 secs.
It's not that hard, I've done that with my HTC Desire before. :) Just google for "disassemble HTC One Mini"
Just one tip: If the case refuses to open, do not try too hard, maybe you're just doing it wrong, think first, then do, it should open easily without putting much pressure and power
Good luck

Mp3s open in Google play after tapping always, have already reset all app preferences. What now?
Thanks for not scrolling by after the first half. This happens in Firefox, irrespective of which site used. The first time it offered the choice of downloading using play or downloads. Naturally I clicked the app I'd be opening it in. Now it just opens the file. After resetting the app preferences three time and closing both promhams after resetting and before trying again. With no obvious solution in Firefox settings. I'm out. Do any of you have any suggestions? Have a nice day.

In the Firefox address bar, enter about:config.
search for download.preferred.
After the search had filtered some items, You will see a preference named browser.download.preferred.audio/mpeg whose value is probably com.google.android.music.
Tap the Reset button at the lower right corner of this preference.

Future tip:
To see preferences you modified yourself, enter about:support, and check under Important Modified Preferences.

HTC Desire 816 CM12 Nightly SMS not working
I just flashed and updated everything on my HTC Desire 816 and everything went just fine. But I followed this APN fix and it doesn't seem to have worked as it should, and I haven't found anything on the thread.
It says I have LTE, it says my network is Virgin Mobile and that I'm in service on the Status page but I can't send any texts and when I scroll the status bar down it says "No Service".
I've never had to mess with APN settings before so I don't know what to do about any of this. The only thing I can do is connect to the internet without WiFi.
Sorry if this is a bit rambling. Like I said I've never had to mess with any APN settings before so I don't know what info is needed.
Also I can't actually find any "APN" settings, only VPN. Is this the same thing?
Another update: I get "No SIM card" when I unlock the screen. But that seems to be the only place

APN -> Access Point Names, while VPN -> Virtual Private Network, both are different and are used for different activities. As for where to find APN, try looking under "Settings -> More -> Mobile Networks -> Access Point Names" and tap Menu key or three vertical dots to add a new APN type.

"No SIM card" message is shown when the device doesn't have a SIM card inserted, or can't detect the SIM card because it's not inserted properly, or the baseband is unknown (may be the case here because it is not an unusual issue in case of flashing a ROM). Do confirm that your IMEI is also intact.

@Firelord I seem to randomly be in a bootloop. It's just stuck on the Cyanogenmod logo.
I guess I'll reflash and see what happens

"Connection problem or invalid MMI code" in Samsung SHV-E160L
I have bought a Samsung SHV-E160L in the Philippines. Lately, I have been facing problems with  signal reception. The SIM card is good because it works on another phone. Could it be the problem on the phone? I am not good at Android terms so please be specific.
The signal bar sometimes is full but cannot make call or text. It sometimes work but mostly it doesn't even if it is showing full strength. It just says "Connection problem or invalid MMI code", and sometimes there's no signal totally  even if the signal is very strong. I took my phone to a  technician but he couldn't find a working solution. I am really getting frustrated because I cannot make calls most of the time and others cannot contact me.

Can't reinstall correct version of google play services
I accidentally installed the wrong version of Google Play Services via an apk, and now it's crashing every 5 minutes and the Google apps don't work.
I tried installing the apk for the right Google Play Services, but it won't install (I think it's because of the signature problems).
The apk install screen just has an "x" saying "app not installed."
I can't uninstall or disable the old/wrong play services.
Any solutions?
Thanks.

Maybe helpful information:
Nexus 4, CM 12.1
The correct version is -436, right?

Try downloading the latest gapps from XDA and flash this from recovery. Google play services will automatically update in the background. Don't install it manually.
Main thread: XDA

I keep on getting an error message when flashing gapps:
"E: footer is wrong
E: signature verification failed
Installation aborted."

You might need to turn off signature verification in recovery. Refer here : https://starburstregional.wordpress.com/starburst-rom-home/resources/how-to-turn-off-signature-verification/. If even that is not working, install Philz or TWRP recovery and try flashing again.

I turned off signature verification in cwm and the gapps flashed fine, but when I rebooted, the old Google Play Services was still there.

Did you clear cache and dalvik cache after flashing?

Purge the Play Services along with the framework completely off the device. Use TitaniumBackup or a system apps remover tool to do the job. Thereafter, flash the GAPPS as @uberz91 said.

I uninstalled play services with TitaniumBackup but flashing gapps didn't install Google Play services, so I installed it with the correct apk. I'm pretty sure it works now, but Android Keyboard (AOSP) keeps crashing. Maybe it's related? Or maybe it has to do with the build of CM12.1 that I installed (20150710).

Phone asking "SIM network unlock PIN" after flashing new Stock ROM on Xperia S
I have Xperia S (LT26i).
Earlier it had 6.2.B.0.211 installed.
I flashed it with "XperiaS_LT26i_6.2.B.1.96_1257-6919.ftf", flashing was successful, but after I started my phone I saw this message "SIM network unlock PIN". What should I do now?
(Click the image to enlarge it)

Try this...
Link to LT26i firmware
You might have flashed different firmware that's the issue or Your phone might be factory locked... Try the solution in the link provided... :-)

I have flashed with the same firmware which u provided in the link. But problem is still there

That means your phone was locked already by service provider... There might be a tool to get unlock code or skip the lock... You have to search on this...

Can a 3G android phone support 4G?
I own a Samsung galaxy note 3 N900 which is a 3G phone.
Its specification include
HSPA+ : HSDPA 42.2 Mbps and HSUPA 5.76 Mbps
In my area, Airtel is providing 3G at the speed of 2 Mbps and 4G at the speed of 10 Mbps.
My phone does not support 4G but it does support 10 Mbps download speed.
Will that 10 Mbps 4G plan work on my phone or not?

I doubt it'll work. 4G works on different frequencies and follows different techniques on how to send or receive data. If your carrier only provides 2mbps via 3G then you have to live with it. It's also interesting to provide 4G at such a low speed, because it spoils the benefit (faster transmission) by limiting it to a speed lower than HSPA+ (which does not require an additional antenna).

your phone doesn't support 4G it supports 3G++ which almost 4g and supports high speed downloads , the short unswer to your question is you can't use the 4g plan proposed by your carrier due to your phone's hardware limitation.
the bright side is HSPA+ is not so bad you will not notice the difference.

Can't flash Unofficial CM 12.1 on GS3
After figuring out how to flash the official Cyanogenmod 11 to my GS3 I thought it was time to pick up a new project, the unofficial 12.
So for some reason I can't flash the unofficial Cyanogenmod 12.1 on my Galaxy S3.
I'm following these install instructions, along with the ones from the CM website because I'm still a bit new.
I flashed the TWRP recovery just fine, I've never used it before, and then pushed the zip to the phone and tried to install. But I get this error:
Updating partition details...
...done
Full SELinux support is present.
Running boot script...

I have the T-Mobile one. Is there a version for this phone?
Or have a just made a huge mistake and misunderstood what the issue is?

You should never try and flash software from a different device, or a different model of the same device. You could end up bricking your phone.
Regardless, d2mo has official CyanogenMod support. You can use the CyanogenMod installer or download a flashable zip from here.

Thank you. I didn't realize that I was using the wrong one. I also didn't realize that Cyanogenmod had an official version.

How to switch a Google account without resetting a phone?
On my Android LG Optimus Dynamic phone I originally entered an incorrect email when setting up the Google account to use. I want to switch emails now, but when I add the correct account and then try to delete the first account, it says it is required by some applications, and that I can only delete it by factory resetting the phone. However, that message does not come up when I try to delete the second account, and it removes fine.
How do I delete that original account so that I only have the new one left without factory resetting my phone? (I don't want to lose all of my apps and my contacts).

Which Android version is it? If you don't receive a working answer, then you can actually take backup of apps and contacts (irrespective of having root access (do you have it?)) and go ahead with factory reset.

Uninstall all Google applications on your phone, such as Google+, Youtube, Google Maps, Chrome, Voice Search etc. Then install the Google Installer app, and install all google applications. After installation, the Google App or Google Account Manager will prompt for account details. You can login with your required Google account. After that, the device will Sync the account to all other Google apps.

Oh sorry, my device is rooted. But since it is rooted, will all the accounts not sync?

You didn't mention the version of Android you're using, but you did mention your device is rooted, so this app: Erazzer may help:

Please try FREE version of this program before buying it.
This program will be very useful if you want to change the main Google account on your android device WITHOUT RESETTING it to the defaults preferences. Some features:

supported on Android 2.x
deleting Google accounts (2 methods)
accounts backup/restore
quick reboot/shutdown
widget for quick operations

Warning! The function "reboot in recovery mode" can DELETE ALL DATA on some devices, it is disabled by defaults. Don't use it unless necessary or you do not know what it is

At this time, the webpage says: "This app is currently not active on Google Play". I don't know what that means, or if it will change.

@helper - I hesitate to approve the edit, but I don't want to reject it either. I don't disagree with the edits, but most (about 90%) of the edit is to make corrections to a section that's a word for word quote from another (linked) website/webpage. That webpage has changed (and is probably no longer maintained), but an old archive of the page can be found here. I don't know it it's appropriate to make corrections to something that is quoted from offsite. Hopefully someone can provide some insight.

Also on Samsung Galaxy A3 (2017) you can add another google account and remove the other one from the Cloud and accounts --> Accounts --> Google then 'Remove account' from top right menu.
It worked for me.

Rooted Galaxy S6 Edge, can I update?
I just rooted my Galaxy S6 Edge using the PingPong root I believe it is called. Just to make sure, it is the root where you take the APK and put it on your phone and click one button and it roots it.
But now I keep getting a popup saying that there is a software update for the phone. How do I update the phone now that it is rooted? If it is not possible, then I have to go without updates, so how do I get rid of the popup??
Thanks guys!!

root will not get you banned from the updates you can update your phone normally via kies on PC or on the phone it self if the update is supported to be flashed from the phone ,however I must add that you will probably lose the root access on your phone after the update

Don't update your phone via root otherwise you will lose your previous root permissions and then you will need to re root your device.

What is this S icon on my android?

I have a S4 android, I have gone through the list of apps (both running and total) but nothing appears to match up. Can anyone please identify this icon?

It's a notification from an app, and it looks like a Samsung logo. I think you should find the corresponding notification on your notification panel.

"Samsung account: A notification about your Samsung account has arrived."

Recovering Wifi Password without Root on Galaxy Note 3
I am trying to recover WiFi password without rooting my phone. There are 2 ways I found online. One using a file explorer and the next is using ADB. I tried using ADB but I failed in doing so. I'm really not sure if I did it right but then I just followed the instructions here from Quora. Anyway, I have pulled the wpa_supplicant.conf and this is the only thing I see:
update_config=1
eapol_version=1
ap_scan=1
fast_reauth=1

I should be seeing this instead of the one above:
network={
ssid="NETWORK_NAME_HERE"
psk="PASSWORD_HERE"
key_mgmt=WPA-PSK
priority=1
}

Is there something that I missed or it's just not really applicable? I have Samsung Galaxy Note 3 SM-N9005.

Just want to confirm, are you also using Cyanogenmod ROM? The fact that you could pull the file using ADB shown that you have root access (which probably was provided by CM), since normally you can't get system file without root.

I was wondering exactly the same: trying to pull that file without root gives you a "permission denied". So as that proves you've got root, you could also try apps for WiFi Password Recovery. Apart from that: Yes, you should see the second part (network block) as well – unless the device had never connected to any network, that is.

@AndrewT. No I'm not using cyanogenmod rom and I did not root my phone.  :)

@Izzy well some say that we can use pull and push without rooting a device. Well I have tried that app but it just scans for wifi. I have been using my phone since 2013 and I'm pretty sure it's not like that. I'm just wondering why there is no network block in my .conf file....

Of course you can pull and push without root – but not everything (some files and directories are protected). And I agree, with that block missing in the file, the recovery app probably won't find it either.

So there's nothing I can do to see the network block without rooting my phone? :(

If you are still connected with wifi than you can recover wifi password by going to your local host in the browser like 192.168.1.1 and than in the password section tick on show password or just click in password field your password will than be revealed to you hope it helps .

My Moto G (2014) stuck on a boot loop while plugged and now doesnt even boot to recovery while unplugged. Any solution?
My Moto G (2014) Indian Version seems to have stuck on a boot loop. When I long press power button to on the phone the sequence of loop is phone vibrates, notification LED blinks for once and the 'Unlocked bootloader' screen appears (before unlocking it was motorola logo) and then screen goes black. This keeps on repeating. And the problem further is this only happens when the phone is plugged in, phone is inoperable when its unplugged.
Solutions I tried:

Flashing the stock ROM: Still the same boot loop
Performed factory by pressing the power button: Nothing
Tried booting in to Recovery mode, but after pressing the Volume Down button the same boot loop starts

I would again like to emphasize the fact that I tried this only when the phone was plugged. Nothing happens when the phone is unplugged. Must be the problem of faulty battery? And also I tried different chargers, no change. Any help will be appreciated.

This is a manufacturing defect. I had the same issue with a Gen 1.
If its still under warranty you can get it replaced

Would you shed some light on what kind of "manufacturing defect" it is? There must be some info about it.

Recovering deleted call logs in Android 5.1.1 - to root or not to root?
I accidentally deleted my call logs/histories and badly need them now. I would like to recover the call logs and tried few softwares. Most of them were not successful in recovering the deleted call logs. Some are asking permission for rooting or superuser access.

Is rooting a right thing to do for recovering my call logs? Will it affect my android phone in any unexpected ways?
Are there any other ways or softwares where I could recover my deleted call logs?

Any help would be appreciated.

SMS and call logs are not backed up by google. So unless you have a backup its unlikely you can recover it. You should have used Super Backup from playstore to backup your call logs/SMS etc. Related

So the recovery apps that ask for superuser/root permission to recover call logs are scam? From what you say there is no way for me at all to get back the old deleted call history.

Does the app listed in playstore? Could you provide the app link(s).? I can only find this android-pc recovery tool but i haven't used it myself. You can give it a try or have you already tried it?. And regarding rooting risks question see Are there any risks to rooting a device?

Worst case scenario, if none of the apps work without rooting and if you dont want to root your device you can still call your service provider for your call log information.

How to force a time/date update in my phone?
I recently changed the battery of my phone, but in doing so, kept it without battery for some time. After placing the new battery, I discovered that the date and time had gone back to default.
I tried to set them both to update from the network but neither is updating. I tried turning the option off and on again but nothing happens.
I can, of course, set the date manually, but I am wondering why it's not updating by itself. The time zone is correct.
I'm using a Samsung Galaxy Pocket, Android 2.3 (Gingerbread).

Do you have root access on your phone?

nothing helped, I set the time manually and then re-enabled the automatic; so one day, whenever it want, it will probably update the datetime itself if needed..

@zackygaurav If you know of a way to update the clock, with root access, could you please post it as an answer here?

try this:

uncheck "update from network"
set it to a wrong time (something that's clearly not right)
close settings (not sure if this is actually needed)
check "update from network" again (which should correct the time)

Try rebooting your device (shut down and restart)
If that doesn't work, try manually setting the date back one month, exit settings, check update from network and reboot your device.
On restart Android should check the network date, see it's wrong and reset the clock.
My tv box's suspend mode screws up the time every time that it's invoked because it either has no realtime clock chip or it doesn't have a capacitor or battery to keep it going. Usually rebooting fixes this)

Just set the time wrongly (manually), then turn on automatic date and time and go back to ...internet. I just tried it (now)

please try this method: set it to "update from the network". Then connect the device to data(internet). Then it will update time automatically. I tried this once.

Thanks for the help but it's not working. I tried like this: turned off both automatic update and internet. Then turned Automatic on, and then turned wifi on. Nothing happened. :(

try by using mobile data.

Exactlly (like it wrote Mr. Rahul Gopi), but you need to wait few minutes connected to internet.

It's possible for the Automatic date and time to be turned off while changing a battery or switching between power-saving-modes.  To turn it back on, go to settings --> Date and time --> then make sure Automatic-date-and-time is turned on.

TL;DR: If you get an error about NET:ERR_CERT_DATE_INVALID that make your tablet stop working, try to set manually DATE and TIME (both) to current one of your timezone.

I was trying to fix my step-parents tablet (old Samsung one, SM-T2.0NU, Android 5.0.2) that stopped working suddenly I was told while on YouTube.
Problems noticed, actions taken, etc. (you can skip to solution):

I had NET:ERR_CERT_DATE_INVALID error in Chrome.  Noticed that some website worked (non-https ones and some others it seems).
Most of the things was not working, like accessing Play Store.  Without any meaningful error message, just an option to "retry".
I thought it was the internet, etc.  So I rebooted router, tablet, removed everything Wifi, disconnect/reconnect, tried to set internet to manually (but it did have an IP automatically), etc.
Cleared Chrome history, cache, etc.
Automatic date and time option was not showing, but I could see the option by using the search, but when I tried to tick it, it bring me to date and time and was not applying any solution.
I tried multiple time to put the time myself...

Solution:

Only after an hour trying to apply gazillion of solutions did I try to put the date in the past to notice the date was already 3 months behind (why? no clue).  Then I set it to today's date and everything started working again.

I don't know if this will trigger the automatic management of date and time (I still cannot check the box even through search in settings), but I might not be the only one falling here to try to fix that issue that was preventing us using the tablet normally (I believe security settings verified that date and time were correct and I saw a lot of people having the same issues without a fix).

Google play: one account multiple devices
I have paid for an app on the Google Play store and I've downloaded it on a device (my Android smartphone). Now I have a tablet, should I pay again for the same app? Or will logging in with the same account allow me to download it to my tablet "for free"?
Differently from question Can I use multiple Android devices with a single Google account? I'm more focused on app for which I've paid to download them, and not simply in app sync.
Since if this is possible, could it be a cracking mechanism? Meaning if a "buyer" account become public (username & password) anybody can use it and download paied app for free.
This could apply for example in a "family" environment for example, one accunt that pay for app and all people having the same account on their device.

It's a dupe since the answer is the same: yes, you can download the paid app as "free" since the app is linked to the account.

It depends of app developer.
Some apps like Evernote, Avira antivirus premium charge once for all devices, whereas others like Icon packs will cost you on individual devices.
This totally depends on the service or app you are talking about.
Good luck

If you own multiple Android devices, you shouldn't have to buy multiple copies of your apps. Fortunately, the Android Market makes it easy to install all of your paid apps on all of your devices without purchasing them again.
Before getting started, please note that these instructions are for devices running the new Android Market (versions 3.0 and higher). While it is possible to install paid apps on multiple devices through the old Android Market, there's one caveat: the Google account used for the purchases must be the primary account associated with the device. In any case, we've included notes that should make the process clear.
Step 1: Make sure the Google account used to purchase your apps is added to your new device. If it isn't, go to your Android Settings, tap "Accounts and sync," then "Add account."
Note: If you are still running the old version of the Android Market (version 2.3), then the desired Google account must be the first account added to your device. This is because the old Market can only access the device's primary account and has no means of switching.
Step 2: Go to the Android Market. Tap Menu, then Accounts. Select the appropriate Google account.
Note: Again, only the new version of the Android Market (3.0 and higher) has this ability.
Step 3: While in the Android Market, tap Menu, then hit My Apps.
Step 4: Scroll down to the bottom of the list, where you should find a section labeled "Not installed." These are all of the applications that have been previously downloaded and/or purchased on your Google Account.
Note: The old Android Market marks each app as either Installed or Purchased. In our case, we are interested in those marked Purchased.
Step 4: Tap any of the paid apps listed to go to the app's Market page. Hit Install.
And it's that simple. You can install your paid apps on as many of your devices as you like, so long as they are connected to the Google account used to purchase the apps.

M8 unlocked when picked up.
I have an HTC m8. The other day I sat it flat on my desk. Every time I would pick it up, the screen would automatically unlock and light up. My thoughts were that's neat how have I never noticed this before, it knows when I pick up the phone. Today I cant get it to do it. I've tried all different positions on flat surfaces and it simply will not wake up upon being picked up. Any thoughts?

It could be those gestures .Try enabling the gestures on settings>Display & Gestures >Motion launch gesture >Enable it.

Android Device manager
I just recently know about Android Device Manager. So i tested it on my own phone (moto g2). Then i thought, lets have some fun. So, i ask for gmail account and password from my friend. After getting that, i went to google in her account and then to Android Device Manager. But her phone (Mi4i) had just two option into it "ring  | enable lock and erase". So i just click on option "enable lock and erase" hoping that before doing anything it will ask yes or no. But instead it said done or something. Just tell how can i undo it and what exactly happened when i clicked that button?? i would really appreciate.

It will erase everything (Internal Storage) on her phone as soon as the device will connect to Google servers? Time to apologize to your friend! Just so you know: "enable lock and erase" -- I think it's plain English, and nothing much is needed. Anyhow, "have some fun". :)

If you are still wondering what did it do, check out this answer by Google.

How to have a clipboard functionality for multiple copy-pasting?
I want to know if there are slots of option in copying:
copy1 copy2
then paste1 paste2
I love surfing many websites but need to login on them. I'm tired of typing every time my email address and password.
Because there is email & password there must be  two or more slots:

for the copy-pasting documents
slot for email
for password
for second email account
for 2nd extra password

but the password must contain 4pin no. to paste
e.g:

save as copypaste 1?
save as copypaste 2?
save as copypaste 3?
save as copypaste 4?
save as link1 --add website link & title
save as link 2
add another slot

What you really want is a password manager -- you are using different passwords for every site, right?.

The category of app you are looking for is called Clipboard Manager.
Well, I have been using the app called Clipboard Everywhere which keeps a history of clipboard items and can be used very easily to recall the items copied before the last copied item.
Alternatively, you can use Clipper
I recommend Clipboard Everywhere as it consumes less ram.
Best of luck.

For additional alternatives, be welcome to check with my list of clipboard apps ;)

Those are good options - is this capability included directly in Android?  I haven't seen such capability built into Android.  EDIT: other than to use like a generic "notepad" and copy/pasting from there.  Generally, I wouldn't want to use an external app for auto-copying anything I copy into its pasteboard (coupled with a password manager, that's asking for trouble, particularly for "shared" or cloud backed clipboard managers).

Use Smart Multi Clipboard, It suits best for your use. Instead of 2-3 multiple copy paste job, this does for more than 50 text items together. It is actually a clipboard manager app that manages all of your copied texts in a stack and allow to paste directly once you click inside a text area.
You can also add your own notes into this. These pre written Pinned notes can be used just as copied items quickly like your address or email/message content.
Get it from Playstore here:
https://play.google.com/store/apps/details?id=com.cv.copybubble

Do you have some association with this app, or are you just a happy customer?

Hi Dan, I think I am the happy customer. But you are free to downvote my answer of you feel the app isn't how I explained or if you don't like it.
PS: I don't have any association with this app, I am just a regular user.

No, there's no problem. Even if you were the author, that would be fine. We just need it to be clear which case is which, so other visitors can judge whether the suggestion is a genuine recommendation or an advert.

Try LastPass.  Everything you are asking for and miles more secure than the clipboard.
https://lastpass.com

Hi, thank you for suggesting this service, but since the main question is actually about multiple copy-paste, this answer doesn't fulfill the main requirement since LastPass is a password manager, not a general clipboard manager. When you have 50 rep, you can suggest this as a comment instead, as already done by josh3736. I hope you understand.

What is this icon on status bar?
I just realized there is new icon in my status bar on left of sound icon

I don't have clue what is that icon, thus I also can't search information about it.
Anyone has advise?

It's the Battery Stamina Mode (Two hands holding the battery).

Battery STAMINA Mode builds on the same technology as Extended
  Standby Mode. You can turn it off if your dont want it in the
  Power management Settings page.
Starting one minute after the screen has been turned off, data traffic
  is automatically blocked and background activities are prevented from
  waking up the system.
When Battery STAMINA Mode is running, you will also get power
  management tips to help you save even more energy, and keep your
  device going even longer. For example, if Battery STAMINA Mode is
  turned off and you leave your device with the screen turned off for
  six hours or more, you will get a recommendation in the notification
  bar to turn on Battery STAMINA Mode. You will also be notified about
  apps that consume a lot of power. [Ref.]

You can also White list some imporatant apps, thus allowing them to run in the background.

Cannot see phone under 'My Computer'
My Galaxy S3 (running CM11) isn't showing at all under My Computer. The phone is set to MTP.
Under my computer the GT-i9300 shows up under 'Unspecified'. When I go into the device properties it shows up as Google Galaxy Nexus ADB Interface even though I have debugging mode turned off.
When I try to update the device manually to MTP USB Device or Samsung Mobile MTP Device I get an error saying "This device cannot start. (Code 10)"
I've tried un-installing and re-installing the drivers, as well as the registry tweaks mentioned in this XDA thread but I do not have the UpperFilter key present. I've also tried installing Kies and running the connection troubleshooter with no luck. Any suggestions please?
Many thanks

It appears that you are using Android Studio (or another IDE). Try turning on developer mode and then connect the device.

Thanks, when I run under developer mode it still won't work unfortuantely :(

@Nick Did you enable USB Debugging? What about verify apps over USB? What happened to me was, I had to wait for an RSA certificate to pop up on my phone to verify that it is connected properly....

Galaxy S3 running CM11 - SystemUpdateService keeps getting disabled
SystemUpdateService is currently destroying my battery (phone awake 98% of the time) because it's not running (The update services acquires a wakelock to check for updates, but since SystemUpdateService is disabled, it never finishes the check and the device stays awake.)
The service is under both of the following apps:

Google Play Services
Google Play Services Framework

If I use the DisableService app I can kick them back into action again... but whenever I restart my phone, they're disabled again. Also, sometimes they randomly switch off again at random.
Any idea how to keep these services running please?
Many thanks

Do you have the app ops option under settings ? if not are you open to install it from play store ?

add more info about your problem, so you want those two google play services running all the time or you don't want them running all the time? (because you said 'Any idea how to keep these services running please?'). Please ask clearly once again.

Thanks @ranjithstar256 - I've just updated the original post with more context :)

Thanks @lord-ralf-adolf - I think I've used this app before, but I've just installed it and will give it another go.

I don't think your problem is that the services not running ,it's a known bug that have been reported on XDA several time and I had and still have it I fixed it by denying wake lock permissions from the google play services (not relly a fix but a work arround) you can try that and tell me if your device is sleeping fine or not

@lord-ralf-adolf I think you could also mention the tool or the tutorial in a comment that you used to deny that wake lock permission (like Amplify or something), and if it works for OP, then it would be worth having it as an answer.

The tool I used is app ops ,I disabled the the following permissions to the Google play services : keep awake ,wake up and auto start

Does Something wrong with the SD card in use refer to an issue with the android software or its an issue realted with the Sd card itself
I recently updated the OS from Jelly bean to Kitkat Android v4.4 and after this update I am not able to download any file from the browser. Every time I try it gives this pop up and the download fails.
I tried even using the Internal memory but still the issue persists.

Screenshot 1 - Something wrong with the SD card in use.Please check if your SD card is available for downloading
Later when I select the default path then it gives me the below popup.This pop's up  even when I am setting the internal/Primary storage as default
I doubt whether the Android v4.4 kitkat allows storage on the SD card for normal downloads

Screenshot 2 - Due to Android policy there are some restrictions in using secondary storage -

Is this problem with "UC Browser" only or with other browsers as well in your device?

For chrome it gets auto downloaded to the internal memory so can't say exactly

Controlling Android device from Android phone
Kind of related to this question.
I want to control my android tablet (galaxy A 9.7 SM-T550, Android 5.0.2) with my Nexus 5 (Android 5.1.1) . Both are rooted and I want to be able to control the whole screen of the tablet using WiFi (wifi hotspot from Nexus 5, to use in the car). I have tried Webkey, but the service wont start. Remote Tablet is able to cast the screen, but no input events is registered.
I haven't found any vnc server that is working for android over wifi, just USB. Any ideas on what to use? I don't care that the apps on both side requires permissions per session.

"Webkey" doesn't work, so which Android is it?

The developer says VMLite VNC server works over Wi-Fi as well.

@Firelord Android versions; Tablet is 5.0.2, N5 is 5.1.1. VMLite VNC Server doesn't start the server when pressing start.

Use "Lock Screen" as Daydream option
maybe its too simple a question, but I need to figure out how I can just use my lock-screen as daydream option for an android lollipop device.
What I want is to see the normal lock screen while charging (specifically wireless charging) instead of turning off the screen. How can I do that?
update July '15: I think it is just not possible - how dull!

I thought of a workaround using Developer Options' Stay Awake while charging, but it makes the phone impossible to auto-lock. Not a problem if you set the lock to instantly and not forgetting to press power button twice to lock (won't post as an answer since it doesn't really work as required, unless requested)

I had also tried that. But very unsatisfactory :)

If you are open to a very simple automation I can suggest

App nationality in Play Store while updating from different location
For some reasons I have to use VPN for downloading apps from play store. I want to know when I change the IP for example to US and my Play Store change to US. Does it give me different app in US edition?
If yes, when I download with VPN and if I turn off the VPN and back to local Play Store I still can update that app downloaded with VPN now. The confusing thing for me is, if I downloaded an app with VPN using US IP address and update it with my real ip what edition of app I get? Does it still update with the US version of the app?

Phone evicting inactive applications from ram, despite plenty of memory free
The phone (Jiayu G4S) is running Android 4.4.2, 2GB of ram, stock jiayu.es rom (kernel 3.4.67)
Stock configuration also sets up some swap in zram, I disabled it, does not seem to make a difference.
Task manager shows at any time at least 0.92GB free or more. It shows at most 12-13 cached inactive apps that are still in ram, a bit more if process limit is manually set to a high value (just for kicks I choose 100).
According to dumpsys meminfo, this is how it looks now:
Total RAM: 2016644 kB
 Free RAM: 883420 kB (230000 cached pss + 131652 cached + 521768 free)
 Used RAM: 852001 kB (805401 used pss + 1684 buffers + 8972 shmem + 35944 slab)
 Lost RAM: 281223 kB
     ZRAM: 4 kB physical used for 0 kB in swap (0 kB total swap)
   Tuning: 256 (large 512), oom 122880 kB, restore limit 40960 kB (high-end-gfx)

And yet, frequently used applications get periodically thrown out from memory (shown in task manager with 0.00b allocated), which results in a small delay at next launch.
oomkiller parameters seem sane
shell@G4:/ $ cat /sys/module/lowmemorykiller/parameters/minfree

Why are frequently used programs kicked out, despite all that free memory? Is there anything I can configure (I have root access)?

And now to answer myself. Looking at Android 4.4.2 (KOT39H) sources, in ProcessList.java we have defined a maximum number of cached apps, set to an arbitrary value of 24:
static final int MAX_CACHED_APPS = 24;

This value is further split as follows by computeEmptyProcessLimit function: 2/3 goes to empty process limit and 1/3 goes to cached process limit.
So now we have an arbitrary limit of 16 for empty and 8 for cached processes. (But go buy a 3GB ram phone, to see how much unused memory you'll have)
In stock android, the only way to change this limit is at runtime, via setProcessLimit(), which requires rooted phone, an application manually installed in /system/priv-app and the SET_PROCESS_LIMIT permission granted.
(In CM11 for example it can also be set in build.prop, but this code is not present in stock 4.4.2)
Luckily there already is such an application on github, called SetAndroidProcessLimit, which, installed correctly, works (my thanks to the author)
Now I have 20 cached apps in ram, that's about all apps I frequently use, and any of them will start instantly, zero delay.

I also figured out how to modify MAX_CACHED_APPS directly in /system/framework/services.jar

download the jar to your pc, unpack the jar
decompile classes.dex with baksmali (or via apktool)
modify in ProcessList.smali and in ActivityManagerService.smali - because this is bytecode, you have to replace not only declaration of MAX_CACHED_APPS but every occurence of it with new desired value
recompile classes.dex
repack the jar
download to phone, replacing original jar (you have to remount rw /system)
reboot the phone; mine automatically will regenerate dalvik cache

SMS notifications and ringtone stopped working on my Sony Xperia M4 Aqua
On an Android Lollipop powered Sony Xperia M4 Aqua, no notifications are being shown for new SMS arrivals in the notification bar nor the ringtone that was set is being played.

As the phone is not mine and I do not have it in my hands it will take some time to test each suggested answer.

Have you tried restarting the phone and the problem persists?

Is the SMS stock app set as the default SMS app you can change that on your phones settings

@Lucky Tried restarting yes

I don't know about SMS but had an issue when manually selected ringtone wasn't playing but defaulted to system ones. Turned out to be a known issue and this answer (deleting data of com.android.providers.media under Settings -> Apps) helped.

Note: Applicable for any Android app which doesn't work in the way it should...
Probably Show notifications (in app manager) for Messaging app might have been disabled. To enable it again just navigate to Settings>Apps>All apps>Messaging and enable Show notifications. If the problem still persists try ---

Clear data and Clear cache on the same page.
Disable & enable the app or Force stop & restart the mobile.

These are the basic steps to troubleshoot the apps which misbehave in any Android phone. If the problem still persists try trusted third-party apps like Textra SMS, GoPro SMS etc. as a temporary solution.
P.S: Factory formatting the phone solves all the problems but resetting is recommended only when it is extremely necessary.

I had this same issue and realized my Sony Z3 was in Stamina mode.  My battery level was at 25% which activated Stamina mode to save battery life by turning off certain functions including the notification light.  Once I charged my phone the notification light started to work again.  Also if you want your notification light to work at all times, just turn off Stamina mode.

Although this was not the issue, Stamina Mode sucks. I only use Ultra Stamina mode to go full stupid phone if I want to conserve battery

This happens when you select any of the priority modes and forget to turn them off. Try doing this:
Settings- Sound and Notifs- App notifs- Messenger- settings icon- Toggle Notifications.

Data Usage For Free eBooks From Google Play Store
How much data does it take to download a free eBook via the Google Play Store? It doesn't tell you as you are installing the book. Does it take heaps in general??

No it does not take heaps of space. Considering its free mostly free ebooks from google play store contains pages lesser than 200. It will be kb's.

I didn't mean in space. Say if I were using my friend's Mobile Hotspot and I downloaded a book, how much data will it take from him? Or even if I used my personal data to download it, how much data would it take?

That very much depends on the size of the book (obviously), so a general answer cannot be given. Is the size not shown along? Have you checked with your web browser?

You can use Data Monitor app from google play store to find per-application basis traffic monitoring. Install this app and check how much data Google Play Book app consumes after downloading the book.
Features:

Automatic data usage measurement - simply start the app once, and it
  will automatically measure your data usage from that point on.
  Whenever you are concerned about your data usage, just open the app to
  check.
High-precision data usage measurement - the app gives an accurate
  measurement of your data usage, without any inconsistencies at any
  moment. Wi-Fi data usage measurements are organized by each SSID.
Easy-to-read statistics screen - measured data usage is separated by
  Wi-Fi usage and mobile usage and displayed in easy-to-read graphs.
  Data usage per app can also be displayed, so you can know which apps
  use the most data.
Transfer speed monitor - a transfer speed monitor can be displayed
  permanently in the upper-right corner of the screen. Instantly check
  when and how much data is being transferred.

Force 720p Resolution on InForce 6540
I'm working with an InForce 6540 board that has 5.0.2 Lollipop installed.
I am trying to connect a display device that has a max resolution of 720p at 60hz. I am using a micro HDMI connection.
The 6540 detects the display as a 1080p dislplay and uses that resolution.
I tried to change the resolution with adb root.

adb shell cat /sys/devices/virtual/graphics/fb1/edid_modes
( to check which modes the display device supports)

adb shell setprop hw.hdmi.resolution 13
(or other supported number, checked the .cpp file to see what each number means for resolution.)

adb shell stop

adb shell start

This did not work, and I tried it on a different display device that supports more resolutions, and it did not work either.
I have also tried the command wm, but that only resizes the amount of screen it is currently using. (It scales versus changing actual display resolution)
My display shows static on the bottom half, and on the top, it shows the whole display but cut. The right side of the display is cut and displayed on the left with everything shifted to the right.
Any help would be appreciated. I know this is not a normal problem.

The resolutions along with the edid modes are also listed in dmesg ( or logcat).  Filter on EDID to get lines such as: "hdmi_edid_add_sink_video_format: EDID: format: 16 [1920x1080 p60 16/9], Supported" - your solution worked on my Note3 Lollipop.. thanks!

If anyone can evaluate the existing answers, feel free to vote accordingly and reopen the question (or mod-flag the question requesting for reopening). For anyone else having the same issue, please post a new question and refer to this question as additional context.

I'm running an older version, 4.1.1, on a cheap tablet. On this unit, it's
Settings-->HDMI-->HDMI Resolution.
HTH

I ran into the same issue on the 6640, the problem I had is that in order for the change to take effect you must unplug the HDMI and plug it back in.
After you call setprop hw.hdmi.resolution try physically unplugging the HDMI display and plugging it back in.

Battery Drain from Android OS and Android System
I've got a Galaxy S5 and recently, Android OS and Android system just seem to be draining my battery.
Not done anything extraordinary regarding rooting or anything, it's all stock.
I can only manage 2 hours screen time - 2 hours 30 if I'm lucky.
Other than running a factory reset. Any ideas?

Related: Battery draining fast because of Android System / Why do “android system” and “androd os” take 30% battery / Why does the Kernel and Android System/Android OS drain my battery? / Is it normal for Android System to be the top battery user? / search results

Might want to post the battery graph and top applications draining power.

I've had some success with mine by going to Settings, Battery, and then the Detail button under Save battery power by managing your apps.
I then set pretty much everything to Auto Stop except for "critical" apps like my launcher, SMS, etc. - anything I want to still get notifications on.
This has significantly improved my battery life.

As Jkubecki said; Android devices face this problem as multiple always seems to run on the back end draining your battery.
So you need to run all the unwanted application to fix this issue. It will certainly show an improvement in your battery duration.

Those apps would show up separately in the stats then, wouldn't they? If I understand the OP correctly, battery stats show "Android OS" and "Android System" as the top consumers (as in the questions I've linked from my comment on the question itself).

Disabled MTP, cannot access setting to enable
I have an AOSP rom of android 5.0. I unchecked the MTP checkbox in the settings, all options turned grey, a few seconds later the activity closed and now I cannot open it again to enable MTP. I've tried restarts and unplugging cable.
The setting under storage > [menu] -> USB computer connection does nothing when I click it.
How can I reenable MTP (or any usb transfer option really)?

Can you mention the content in /data/property/persist.sys.usb.config? 2) In my CM12, the activity is com.android.settings/.UsbSettings 3) If it ever happens again with some other settings, use dumpsys activity recents to quickly note the recent activities.

diag,serial_smd,serial_tty,rmnet_bam,mass_storage,adb

I can launch the activity that way (same activity name as you said), but it closes immediately, with or without computer connected through USB.

How Do I Get Rid of Apps from Play Store Update List?
For the past few months, I have had the following items in my Play Store update list:

I do not have these apps installed on my device. I do not want these apps installed on my device. Yet I do not see a way to get rid of them from this update list.
How can I get rid of these apps from my update list?

possible duplicate of How to get rid of update notifications for a given app in Google Play Store?

@Firelord: Two of the answers there cite a discontinued app that does not actually solve the problem, one requires root, and the last one requires you to install the app (then disable it). Thanks, though!

Seems like they must have at least been pre-installed if they're presenting updates, otherwise that would be fairly unusual. They don't appear in Settings → Apps → All?

No, neither are in Settings → Apps → All. FWIW, this is a Nexus 4 running stock Android 5.1.1. They are not listed in disabled apps either, though I have disabled Google Drive.

I think these apps were separated from the Google Drive app (Source, Source 2). I assume that because it previously included the functionality that these apps provide they somehow appear as updates.

@bmdixon I would agree but Google Drive is disabled in OP's device, and Play Store also knows which apps are disabled, so it seems odd that Play Store is still suggesting them when Drive is already disabled by owner of the device. // Though I would say, if nothing works (as non-root) then just download them and disable them, to get rid from update list at least.

Try going to "Settings > Apps > Google Play" and then pressing the "Clear Data" button. Then go back into Google Play Store. You may have to sign in again but I doubt it.

If you haven't installed the application than most probably its a System Application and cannot be removed permanently as the APK is stored under /system/app or /system/priv-app directory. It can only be disabled and whenever you factory reset the phone, the application will come up again.
You can try doing this:
Goto Settings>Apps>Select the App you want to remove > Disable(Assuming that you do not want to use this application)
And then check in Play Store, it will be removed.
Hope it helps.

"Unknown" vs "Private number" on the Samsung Galaxy S3's stock call log
I've recently got two calls on my Samsung Galaxy S3 with stock (TouchWiz) firmware. One was marked as coming from a "Private number", while the sender of the second one was apparently "Unknown". Neither of these displayed a phone number when selected in the call log. Can anyone explain the difference between a "Private number" and an "Unknown" one?

A private number is that when the caller holds back his phone number with the help of the service provider and the service provider doesn't send the Caller ID information to the call receiver then it considered a "Private Number".
To activate the feature ,

Open Dialer > 3 dots > Settings > Call Settings -> Sim related call
  settings > Additional settings > Caller ID

Note: Not all carriers allow hiding the Caller ID. Mostly it is greyed out for security purposes.
On the other hand, when your telephone exchange(service provider) is unable to register the Caller's number, then it is called then it is called "unknown".

how do you block unknown calls?

Photos downloaded from facebook are appearing in Google Photos
Photos I download with the Facebook app on my Samsung Galaxy Note 3 are synced to Google Photos. I would like only photos I take with my phone's camera or add manually to appear in Google Photos. Is this possible? How?
No folders are selected in the "Choose folders to back up..." dialogue.

Have you turned on Auto-sync of your Google photos. It will backup the photos in your phone automatically if you set to sync automatically.

In the Photos app, Settings -> Backup & sync -> Backup is set to on. Camera photos are beeing synced, along with unwanted photos from Facebook.

there is a simple solution to hide facebook downloaded pictures from google photo or the stock galery or technically speaking hide them from the android media scanner.

locate where the photos are downloaded facebook download to your external storage /DCIM/facebook and the facebook messenger app store it's pictures under /pictures/messenger
use a file manager app like es file explorer navigate to the location of the pictures and create a new file name it .nomedia
it's done the pictures downloaded from facebook will not show in the google photo.

.nomedia will hide the pictures from all image viewing apps, so this is not a solution.

sorry that's all I got for you because facebook puts it's photos under /DCIM and google photos sync /DCIM  if you can change the location where facebook app store the downloaded pictures elsewhere you will fix this problem

As written by me here:
I had EXACTLY the same problem. I couldn't find a solution else where. The only solution was to use a .nomedia file in the /sdcard/DCIM/Facebook directory and moving the *.jpgs to another folder. I had made a Tasker task referring to a reddit post in /r/tasker. Here is the description and the XML for importing it. You have to create the %destpart and add a .nomedia in %sourcepath for it to work. You can run this task in a profile as an exit task for Facebook and as an entry task for other messenger apps like Telegram/Whatsapp, etc. so you get your memes right!

Listen to wireless traffic with TCPDump
I am trying to sniff traffic from a smartphone on the local WiFi network (in a legal way).
For that purpose I use the command TCPDump on a computer connected to the same wireless network.
I can sniff packets from iPhones, from a Galaxy phone with Android 5, but not from a Galaxy with Android 4.4.2.
With this device I can only sniff ICMP traffic, which is what is used for ping request. Instead of that I have nothing.
How can this be possible ? What can I do to sniff packets as I do with iPhones ? Does not Android used broadcasted messages for establishing a communication with an access point ?
Thank you.

In order to do that, I'd recommend the app Intercepter-NG. It's a bit tricky to use, and is known to generate false positives in anti-virus software, but it seems to be the only choice.
How to use Intercepter-NG
As soon as the app starts up, select "Skip scanning" and, in the newly opened activity, choose the tab with the Wireshark icon. Press the Play/Start button to begin sniffing. The packets will be displayed on the screen, as well as saved to a PCAP file on the SD card.

Hi Arielle and thank you for your response. I am sorry I was unclear, I want to listen to traffic coming from a smartphone, not sniffing using the smartphone.
For that purpose I use a computer connected to the same WiFi access point and on the same local network than the smartphone.

In that case, I'm afraid your question is off-topic for Android Enthusiasts. Try asking over at Super User.

Have had to reflash CM 11 on my Nook HD+ several times
So I have Cyanogenmod 11 on my Nook HD+ and after just a month or so it starts performing awfully!
To the point I can't use it and have to reflash CM 11. I've had to do it several times in the last 5 or 6 months.
It will reboot itself randomly. It's also so laggy sometimes I can't even unlock it because when I swipe to unlock it, it either won't register the touch or the animation will seem to be so slow it turns the screen off before it gets to the lock symbol and I won't be able to give it anymore input.
I guess my question is: have I done something wrong with the flash or is this my HD+ dying?
On a side note after I flashed CM 11 for the first time if I let the battery die, I won't be able to turn it back on for days until it decides I can use it. I avoid this but just not letting it die.
Also the screen will sometimes turn to "snow"...? I'm not sure how else to describe it, it happens quickly but it looks like noise/snow on an old TV, and it usually happens on the lock screen.

Try a different ROM (stable, not nightly) and see what happens.

What version are you using of CM11, a nightly or is it a snapshot? One thing you might want to do is when you reflash, before you do, go into recovery and do a Factory Reset.

CM is a very interesting mod. I have had the same issues. One of the options you can try is when it gets laggy is to change the theme from the Hex to the Holo (android default) and it can help with the lag and lack of response.
That is what I did and I have not had issues.

Try CM 12 : forum.xda-developers.com/nook-hd/development/rom-unofficial-cm12-0-nookhd-lp-5-0-x-t2993613
 I find that this is more stable than 10.2.1 or any of the snapshots.

unrecognized message, now all locked out
I allowed my nephew to play with my Samsung tab 3 and it is now saying that I have accessed an account without being authorized and is asking for a password that I have never set, what can I do, without doing a factory reset?

Remove that account from your tablet?

That sounds similar to cryptolocker, without the paying to release your device. Try booting in safe mode(look up how, it varies) and taking off what your child used.

Easiest way to add a font so Chrome will recognize it on a Nexus 10?
I want Chrome for Android to recognize the Verdana font on a Nexus 10.  That's it.  Currently, it only seems to recognize Arial, Open Sans, Times New Roman, and a couple of fixed width fonts.  All of these fonts are just terrible, and I'm left baffled by why Google would make such a tiny number of fonts available.
Is there a solution to this that does not involve rooting?  I've spent a few hours in the app store and looking it up online and I haven't been able to find anything.
(Ideally, I'd like to be able to also change the default fonts for Chrome for Android; but that's likely more impossible and is far less important to me.)

Have you seen our fonts tag-wiki yet, Trixie? You might wish to follow it up to How can I install custom fonts on Android?

Verdana is a proprietary font. Although Microsoft once released it as a part of Core fonts for the Web, they didn't allow to repackage it with other products, and then shut the whole project down.
Android has its own Roboto font.

This doesn't answer either of my questions, which remain valid because it is legal to download and use Verdana as an end-user.  Roboto is not a substitute because "Verdana" will default to Arial (or something that looks very much like Arial).

Yeah, sorry for that. I wasn't sure, if you are doing that just for yourself, or as a publicly available thing. What I would do in this case, is taking Verdana as a web font, changing the default user agent stylesheet for Chromium and rebuilding it myself.

S6 Android 5.0.2 account sync missing
I cant find option in ANdroid 5.0.2 to disbale or enable sync for a particular apps.
Say i have 3 accounts and i want to enable contact sync just for one account, but in my case it is enabled for all 3 accounts. same as sync app data which is enabled to all 3 accounts. How do i disable individual app sync?
In my s4 i was able to uncheck a particular app to ignore it from sync, but in s6 i cant find those checkboxes. Not sure if this was changed in Lollipop. Could anyone help me out, please.

Great quality Mobizen recordings?
I recently started using Mobizen for my Android and the quality of the real time recording from the phone to my computer screen is very low quality.
Does anyone know how to improve the quality without significantly increase the delay time during USB connection?
If there are no methods to getting a better quality recording is there an alternative to Mobizen which does NOT require rooting?

I don't know about improving the quality on Mobizen as I don't use it but an alternative would be to use ADB's screenrecord. But seeing as (as far as I am aware) Mobizen uses this anyway, the recording quality would probably not be much better. You could try a different USB cable or changing the bitrate while using adb screenrecord.

What does "Archive does not contain 'android-something.txt'" mean?
So I am trying to flash my OnePlus One with CM12s through fastboot on command prompt, but whenever I type fastboot update romname.zip I am presented with:
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt

the specific build I am using can be found here It is the build ending in 8, or the one submitted on 2015-07-08
What have I done wrong?

I never flashed a ROM using a .zip in fastboot. The proper way I've ever seen is to flash individual files, and some of the important commands are:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img // 64GB users need userdata_64G.img

Provided that you do have these individual files in your .zip.
These kind of zips are called as "fastboot zips" or "fastboot images", while those requiring a custom Recovery (as keepclam mentioned) are plainly known as normal recovery-flashable zips.
I'm not aware of custom ROMs providing "fastboot zips", but if you intend to gain an experience of flashing such zips, I would suggest flashing a stock CM12s. You can find the related info on OnePlus Forums here.
About the error, it says you don't have android-info.txt. That's true that you probably don't have it because as I said custom ROMs usually don't provide "fastboot zips" which has this file. And I also said to try stock CM12s fastboot zip since it has that android-info.txt whose content would be like:
require version-trustzone=TZ.BF.2.0-2.0.0109

I think things would be clear for now.

None of these .img's exist for pixel phones at this point.

@IgorGanapolsky I have not flashed a phone using fastboot images in the last two years so I'm afraid I cannot update my answer. Please do post an answer if you have one; downvote mine if you think that would be just; or raise a bounty to seek an updated answer. :)

Comments are not for extended discussion; this conversation has been moved to chat.

You need to flash custom ROMs from within recovery, not within the bootloader. Detailed instrunctions on how to install CyanogenMod can be found here.
NOTE: those instructions are not for the Cyanogen, Inc. factory images. Offical factory images can be found on the Cyanogen, Inc. website
