comment Why voice records are not saved in mp3 format?
Ogg Vorbis and AAC are also lossy compression formats, like MP3.

comment Find what app is causing popups, NOT in notification bar
In Settings, under Apps. Tap on an app to open its details, and there's a section that shows what permissions it has. There are also third-party apps that'll scan all your installed apps and group them by permissions so you don't have to check each one individually. And Android 6 (Marshmallow) has an advanced section specifically for controlling which apps can draw over others — tap the gear icon at the top of the screen in the apps list.

comment Difference between Linux containers and Dalvik VM in Android
The Dalvik VM is a program. Each app runs a separate copy of it. And the reason for running different apps under different user IDs is so that they can't access each other's files; each app's data is private to that app.

comment How to keep the phone screen on while charging?
Factory reset also erases everything on your phone. That's not really a solution for how to just hide the developer settings again.

comment MAC address randomized on reboot
This is a device-specific problem, and I don't know the answer for your specific device. However, I've resolved a similar problem on a different device, and in that case, the cause was that the bootloader wasn't passing the MAC address to the kernel during startup. The random MAC is just a fallback for when the kernel doesn't know what the address actually should be. The workings of the bootloader are probably different on your tablet, and the entire cause of the problem might be different, but hopefully this helps.

comment had a message from "android.lockmaster.com: saying a virus was on my phone?
Sounds like malware trying to trick you into doing something.

comment Do any google apps have any special privileges that normal apps don't have?
Ability to install other apps when sideloading is disabled, as the Play Store app does, is one. The full list of permissions includes some whose protection level is "system" (meaning it has to be preinstalled on the device), or "signature" (meaning that it has to be signed with a key that the system is preconfigured to trust). But not all the permissions there have a protection level listed.

comment Tablet shuts down due to low battery when battery meter is above 10%
I don't doubt that the battery's capacity is diminished, but I'd expect that to just make it go from 100% to 0% more quickly overall — not to drop from (around) 15% to 0% in an instant.

comment Launch app with UI in background
Apps can run services in the background, but activities are for UI; it doesn't really make sense to run an activity without displaying it. If the app has useful stuff that it can do when it's not in the foreground, it should do it in a service.

comment Help me please someone
There's not enough detail here to tell what's actually wrong with your phone. But if you get a popup that says you have a virus from visiting adult sites, that's likely to be a scam, or something trying to trick you into buying antivirus software.

comment Install/Run Android Skype on ARM LInux?
It's more than just needing Dalvik. Much of the Android API (such as the whole UI layer) is specific to Android and not available on other platforms.

comment How long can I reasonably expect security updates to be supported?
Note that most devices probably didn't need updates for Heartbleed. Reportedly, only Android 4.1.1 was vulnerable.

comment Stagefright security issue: what can a regular user do to mitigate the issue without a patch?
The "group messaging" checkbox looks like it controls sending MMS, not receiving. That shouldn't be a risk. But turning off "auto-retrieve" seems like it'd prevent the phone from being able to display the contents of a malicious MMS. What additional protection does the APN change provide?

comment Can an Android device's security be circumvented when its screen is being changed?
This is no different from letting someone use a phone whose screen isn't broken.

comment Why is Android so fragmented?
This is similar to another question that I've answered in the past, though different enough that I won't call it a duplicate.

comment Updating from version 4.4 to version 5 let me to a dead phone
The "no command" screen isn't an error, that's just the normal appearance of the recovery system (which you told the phone to boot by holding the volume and power buttons). The fact that you can boot recovery means your phone isn't completely dead; it's just the regular Android OS that's (apparently) having trouble.

comment Previously Rooted Nexus 5 is not recognized via USB after stock 5.0 OTA update
"No command" in recovery mode isn't an error; that's just what the stock recovery looks like when you boot it directly (rather than as part of an update).

comment How can someone else read my Text Messages
Android Beam doesn't send any data unless the user of the sending device taps the screen to send what's displayed. You can't just suck messages out of someone's phone by putting your own phone near it.

comment Nexus 5 Change Resolution/DPI
You could, yes. But it's still simpler and safer to use an AVD.

comment Rubbish storage
It's unclear what you mean by "which was also as I was only allocated 8GB", but if the salesperson lied to you about the storage capacity in order to sell you the phone, you should return it with a complaint.
