Why does my phone keep telling me it has low storage?

Many times it is not the apps themselves taking up all the internal storage, but rather data they keep cached (i.e. not your mentioned 5 text messages, but rather things like browser cache, temporary files (though the latter should be gone on reboot), and the like).

Now while you can go to the place mentioned by Narayanan to check all apps separately (Settings->Applications->Storage use) for cache used (and tap the delete-cache button where appliable), and you probably have to start that way as your limited internal storage most likely doesn't allow for additional apps being installed, there are apps around to ease these steps:

eClean is a high-rated app claiming to automatically care for a lot of cache storage like app cache, search- and browser history and more, and even claims it can do so automatically (starting an on-boot service)
1Tap Cleaner is a similar, also high rated app
1-Tap Clean Cache has a high rating as well, and cares for your apps cache
Cache Cleaner is another high-rated app caring for caches and history

Many more apps are available on the play store, but the mentioned four give you a good starting point. Of course, if you are low on internal storage, and run at least Android 2.2 or higher, you could also consider moving some of your rarely used app to SD using App2SD. Moreover, uninstalling apps no longer used is always a good idea.

Not that the platform matters, though. It's a usability feature for a form factor after all.


Does adb reboot recovery require unlock?

What you are seeing is the recovery.  You've successfully booted into it.  It displays that image when it hasn't been told by the main OS what it should do (e.g. something like a system upgrade).

However, it's the the stock recovery that comes with the device, which isn't really useful for much besides doing factory resets.  When someone tells you to "flash the zip in recovery", they're assuming that you've replaced the phone's stock recovery with a custom one such as TWRP or CWM.  Installing one of those does require unlocking.


Sending intents with adb with ACTION_VIEW, setData, and putExtra?

The Android developer documentation explains how to specify an intent in the argument to the am command.

In your case you want -a to specify the action, -d to specify the data URI, and --ez to specify a Boolean extra. You can find the action name by looking up Intent.ACTION_VIEW in the documentation. Putting all of that together, you get:-

am start -a android.intent.action.VIEW -d com.glass.videoglass:// --ez startFromWS true


As a last ditch effort, you could try this:

Use Titanium Backup to backup all your Apps + Data.
Reset the phone to factory defaults.
Restore all apps and data except for Activesync.

This will definitely fix your issues.  Question is, "Is it worth the effort?"


Download internet pictures become low quality

I think it's to do with the resolution of the wall paper you downloaded - it's 1080 * 1920 image , which is not high enough to be scaled properly on your device without blemishes as noticed by you

Typical Hi resolution wallpapers which give a better result are in the region of 1240 * 2208. You could Google those for the solid colours you are looking for or use an app like Solid Colours ( I haven't tried that app but use a different app that gives jet black wallpaper )


Force volume buttons to always change Media Volume

There is no setting for this as I'm sure you know. The only way l see this working is if you potentially write an app to capture all volume button changes and then act on the changes from within the app.

You could potentially use registerMediaButtonEventReceiver to register your app as a BroadcastReceiver for all media button calls. I say potentially because I'm not 100% sure if this BroadcastReceiver will handle these Intents since I'm purely looking at documentation and haven't actually tried this myself.


ask for app rating or review in Google Play, when uninstalling app

This is a Google Play Store feature and is not dependent on the Android Version

Features of Play store which frequently change or sunset and there is no way to revert to earlier behaviour. For instance, Play Store asks for a review as mentioned here, a feature earlier not present
Why has Google started asking questions when reviewing apps in Play Store?


Is it possible to minimize the unlock section of the lock screen?

There is an option to minimize the unlock section by default in the lock screen section of the Settings app.

Maximize Widgets

Restart the phone in recovery. Remove your battery, put it back and then turn the phone on while holding down VOLUME UP and the HOME KEY. Navigate to Advanced, then clear cache and wipe dalvik. Try and restart. If it doesn't work, download Samsung Kies on your computer and try Emergency Firmwire Initialisation. If that still doesn't work... Format your phone from recovery.


"maps is offline check your network connection" on Mobile Data

I found out the problem.
It happened after I put a secondary SIM card for a while and used it.
Then when I switched back to the original Sim card while keeping the second one in, I didn't have a connection anymore.
Seems it gets stuck trying to use the secondary sim card even if it's off.
Solution: Remove the secondary card.


Need help with orignal samsung touchwiz ROM Recovery

in response to you question :

Part A

yes you can go back to touchwizz any time you want by flashing an officiel firmware or by flashing a custom rom based on a stock rom.

part B

grab a firmware from this page
grab Odin flashing tool from here
install samsung drivers (here)
unzip the firmware you just download you will get one file with .tar or .tar.md5.
Now lets make sure you do a fresh install ,boot to recovery and do a full wipe don't reboot the system power off the device after the full wipe and boot to download mod.
unzip odin archive and execute Odin executable file.
plug your device to your PC via USB cable (the device must be in download mod)
An “Added!!” massage will appear in Odin’s message box. If you don’t get the same then you should try another USB port (try USB port located in back in your desktop PC). If that too don’t work then you should reinstall the driver. If you successfully see the “Added!!” message in Odin then you are ready to go in next step. You should also see COM port with a number in Yellow if you successfully added your device.
Click the AP Button, and select that .tar.md5 file
In Odin window, make sure only Auto Reboot and F. Reset Time checkboxes are selected.
hit the START button to begin the flashing process ,when the process is working don't open other applications on you PC don't touch the PC or the usb cable or the phone
Once flashing completed, your Galaxy S3 Neo GT-I9301I will restart and soon you will see a PASS message with green background in the left-most box at the very top of the Odin. You can now unplug the USB cable to disconnect your device from computer.


As it only optimised one app, and not all, it means that this app had to be recompiled. It is possible that this app had just been updated, and failed to get compiled at installation, but it's more likely that some file(s) needed by the already compiled app had been corrupted. As your phone rebooted, this app was probably a critical system app, the failure of which caused the kernel to panic (strictly speaking, a panic isn't a crash, but an active decision by the kernel to shut operations down immediately).

Data corruption shouldn't occur on a healthy storage device, but nothing is perfect, and it occasionally does. If this doesn't happen again, you needn't worry, but if it does, it may indicate that the internal storage in your phone is starting to fail. This eventually happens to all storage devicees, flash storage as well as magnetic and optical media. Back up your personal data as often as you can, and consider getting a new phone. If it does not only happen again, but does so more and more frequently, you should definitely get a new phone as soon as possible.

Theoretically it could be a virus that corrupted the file(s), but a virus that infects apps in a way that the apps or the kernel can detect, wouldn't be very cleverly designed, so I seriously doubt that this is the case.


"sendmsg: Connection refused" trying to root a Nexus One

As far as I know, a fully updated N1 won't have any exploitable vulnerabilities to allow you to root the device. Most of the older "one click" and similar methods used things like Gingerbreak, which were holes in Android that eventually got patched. I have not seen a root exploit on vanilla Android since Gingerbreak.

XDA's wiki has a couple of different options regarding the N1 which work but require unlocking the bootloader, and unlocking will perform a factory reset automatically. They can be found here and basically amount to:

Unlock the bootloader from fastboot mode with fastboot oem unlock
Flash a custom recovery (usually ClockworkMod)
Flash a zip file from recovery that will install su and Superuser for you
Reboot


Is it possible to read IMEI from emergency call dialer?

No. The system does a check against a list of numbers (provided by system property ril.ecclist/ro.ril.ecclist; by detecting the current country or locale) and if that doesn't match with the available numbers, it doesn't proceed with the dialing and informs the user.

Maximum (micro) SD card speed class for HTC EVO?

It looks like someone sent HTC an email back in July and got the following response:

  I understand you want to know which speed is the best for your device as far as SD card is concerned. We have tested the devices on a class 4 speed. I could not recommend anything higher than that. The phone may be capable of running a higher-class speed, but we have only tested it on a class 4.

You may also want to email HTC support and see what they officially say.  From I've been reading, people have been using Class 6 just fine.  Not sure about 8 or 10.


Trouble installing custom rom on Samsung GT-P3110

Ok I have had this problem before. I have a gt-p3113 esspressowifi, your version is the gt-p3110 right? if it is the gt-p3100 w/SIM card the roms for the 3113 and 3110 will not work for it so make sure you have the right version for your tablet. Next dissable the md5 check in recovery, I found out that  the roms for the 3110 and 3113 are near identical except for the IR blaster on the gt-p3113 so both should work for the same tab, if all else fails open the rom on your computer as a zip and change the build prop to conform to your device also change the updater script but you shouldn't need to do that. To test this theory go to cyanogenmod and download the three roms for 3110, 3100, and 3113 and try all three of them after of course be sure your rooted, latest recovery {Philz touch, CWM, TWRP, etc} and SuperSu binary. I used ODIN 3.07 to flash the CF-autoroot file{search CFautoroot} on google search or whatever, install the correct usb drivers for samsung mobile devices on your computer, then reboot your tablet to download mode by turning the power off then turning it back on pressing the power button plus the volume down button at the same time{green android comes on screen with warning about software}. Flash the CF-autoroot targz or md5 file with ODIN 3.07 then use whatever rom you like, if you still have a problem you should start over with the stock rom from samsung kies then do this process over again because you maybe are missing a step here and may need to redo the whole process to bring the root back and open bootloader by the way to open the bootloader you should have android debug bridge on your computer, the process is as follows, boot to download mode open the adb terminal connect your tab to pc  then enter the command= fastboot devices it should show your device number in the terminal window then enter= fastboot oem unlock. might be different but you shouldn't need to do that anyway but if still need to unlock it try odin with the CF autoroot bootloader flasher zip file to flash new compatible bootloader.

If you cannot factory reset from  Android due to  a server policy, you can do a hard reboot via the recovery mode. From LG's website1:

  Using the hard reset

  If you cannot recall your unlock pattern, PIN, or password, you need to perform a hard reset to access your phone.

  When the phone is turned off, press and hold the Home Key  + Volume Down Key  +Power/Lock Key . When the screen shows the LG logo, release thePower/Lock Key .

  When the screen displays an Android robot animation, release the other keys.

  Leave your phone for at least a minute while it performs the hard reset, then your phone will reboot.

That should bypass any policy. Of course,  all the user data will be wiped.

I found a workaround: using the Shortcutter app for custom QuickSetting tiles, it's possible to add a "next alarm" icon (and several other tweaks too).


Is there a way to automatically change notification ringer&volume, differentiating email, sms and calendar via profiles?

The Llama app supports “LlamaTones” — notification sounds which change according to the current profile. See this blog post for the description by the app developer.

You could achieve what you want as follows:

Create separate profiles for every different configuration you want to have.
Edit one of profiles and create a LlamaTone named “SMS”; select a notification sound for it which should be used when that profile is active. To make the notification silent, select a “No Sound” ringtone (at least on CyanogenMod 9 it is available in the “Ringtones” group; if there is no such ringtone on your phone, you should be able to find a no-sound .mp3 and add it easily).

Repeat this step to create LlamaTones for all other apps which need to be controlled separately (you can create a single LlamaTone for a group of apps which should use the same notification sound).
Now edit all other profiles and configure all LlamaTones there, setting notification sounds which are appropriate for these profiles.
Configure your apps to use the newly created LlamaTones as notification sounds.
You can either switch profiles manually, or configure Llama events to switch them according to the current time or any other available triggers.

Note that there is no way to set different volumes for different LlamaTones — the same notification volume is used, but this volume can be set in the profile. However, you can use a sound editor to change sound volume in audio files, and then use those audio files as custom notification sounds, e.g., like this.

Multiple devices on a single Google account - App/Setting Syncing

No, there is no built-in way to sync apps between devices. Google Play backups are generally only accessed when restoring apps onto a new device (or one that was factory reset).

If you have root on the devices, you can manually sync app data. You could copy the data folder for each app manually. Or you could use Titanium Backup or any other backup app to do it for you.

With the paid version of Titanium Backup, you can back up and restore from Google Drive or Dropbox, so it can be done wirelessly. And you can set up schedules to automatically backup certain apps. Restoring on the other devices would still be a manual process, though.

Essentially, if the specific app developer didn't create a built-in way to sync itself across other devices, you'll have to do some tedious manual work to shuffle data around.


What is the scope of Google Play Protect's scanning?

From experience

  Does Google Play Protect only scan apps installed via the Google Play Store or does it scan all installed apps?

It checks for all apps installed on the device irrespective of source (barring systemless installs using Magisk). For instance V4A (Viper for Android) flashed through TWRP triggered this warning

  Does it scan APK files on the device that are not installed?

No, it does not scan APKs. I was transferring APKs of old versions of apps which I prefer over current version and inadvertently copied Lucky Patcher APK. Since I didn't install it, it passed checks


How to disable Google synchronization on Xperia XZ1 Compact?

Ahh. I found that "auto-sync account data" (shown on the first screenshot) acts as a master switch. Turning it on and then going to the "Account sync" screen then reveals the individual on/off sliders for the different items.


Is system apps and pre-installed apps two different concepts?

I think I might have been found the difference. According to this link :

  If an app is signed with System Signature, then its not allowed to
  Disable that app.Also , not all preloaded apps have system signature.

So among the apps within /system/app directory, we have two types of pre-installed apps. System signed with more privileges and normal apps.


How do I increase the size of logcat buffers?

To find out the actual size of the ring buffer, you can use

$ adb logcat -g

To adjust the size of the ring buffer, you might try

$ adb logcat -r <kbytes>

At least that's what some tutorials say. For more details, you might want to read "adb logcat" Command Options and Log Buffers.

P.S.: I guess those settings (manual adjusted ring buffer size) will not survive a reboot -- just to consider.


What's wrong with the MHL connector (for HDMI output) on the Samsung Galaxy S3

Samsung has changed the "pin layout" on this port so that it is not compatible with standard MHL accessories - even ones made by Samsung.

If you want this functionality (HDMI out) for your SGS3, you will need to buy the Samsung adapter that is made specifically for this phone model, and you won't be able to re-use that adapter with other devices.

Personally, I think it is better to avoid buying the Samsung adapter.  For starters, it is getting such that you don't know what you are getting with Samsung mobile accessories.  They have done this before (e.g. the pseudo-PDMI connector on their tablets) and are now labelling products as MHL that are incompatible with the MHL standard and other products.

As well as causing confusion and extra expense for their users, this undermines this useful emerging standard, is inconvenient and inefficient, and it is bad for the environment as it blocks the re-use of accessories.

But I don't mean to turn this into an anti-Samsung post at all - I think the SGS3 is a great phone.  They are, of course, just trying to increase their accessory revenues.  It is up to consumers now - if this move does not increase their accessory revenue then they probably won't repeat it.

Galaxy Note 1 - Hangs on start up screen

I had same issue with my Galaxy Note 1, this happens mostly because of the reasons such as, Software Bugs, Software Manipulation, Stuck After An Update, Malfunctioning Apps or Defective Memory Card.

The Solution for this is pretty easy you just have to Wipe Cache Partition.

Wiping the cache partition of your phone allows you to remove the cache files which may have been corrupted and caused the phone to power off. There is a possibility that the corrupt cache files may not allow your phone to power On. These cache files are temporary in nature and will be created by the phone once again after you wipe out the current cache files. In order to wipe the cache partition, you need to enter the recovery mode by pressing a specific combination of keys. The combination varies from one Android device to another. Here are some examples:

Samsung: Power button, Volume Down button, Home button.

Nexus: Power button, Volume Down and Volume Up

LG: Power button and Volume Down button

HTC: Volume down and Power button.

To wipe the cache partition, follow these steps:

Press and hold the Power button, the Volume Down button, and the Home
button (for Samsung) all at the same time.
Once you see the Android icon, release the Power button but continue
to press and hold the other two buttons till you see the System
Recover screen.
You will see a menu with many options. Use the Volume Down key to
highlight the option that says ‘Wipe Cache Partition’.
Select the option by using the Power key and the process of wiping
out the cache partition will initiate.

Once it completes, your phone will automatically reboot and new cache files will be built by your phone. If you are able to go through the entire process successfully and your phone switches on, Voila!! your problem is fixed, but if your Samsung Galaxy won’t turn on or charge even after wiping the cache partition then you must consider resetting the phone to factory settings.

Do let me know happens, after trying my suggested fix.


Go to the list of folders by clicking on the folder icon next to the IMAP account listed under the Accounts view. That's your list of folder's you'd like to update. Tap the three dots in the lower right. There should be an item called "refresh folder list."


Why are the checkboxes different on different devices?

Theming is independent of the launcher, although both may be considered part of the UI; for example, the TouchWiz launcher and theme are elements of Samsung's TouchWiz UI.

My Samsung Vibrant is running a custom ROM called Bionix, and they've re-themed the device so my checkboxes look like this (perhaps the only thing I dislike about the ROM):


Clear the browser by hitting the settings on your phone.

OTG Is it possible to connect two devices

YES - it is possible. It seems thought your phone/tablet has to be rooted. I've tried all the apps I found without root and could only connect one device at a time.

How to Root Galaxy S5 (SM-G900A) running Lollipop 5.1.1?

As in the comment by @AndrewT., it appears that AT&T have locked the device against rooting (corrected the exploits used by these one-click root solutions back with Android 5.0).

From the link in the comment:

Emphasis and comments mine

  ...the fact remains that AT&T's Android 4.4.4, released in 2014, and Android 5.0 and 5.1.1, released in 2015, have all been unrootable and no-one in the worldwide rooting community has found a root method apart from downgrading to the AT&T, Android 4.4.2, NCE, firmware/kernel... [to get] an exploit that AT&T closed off almost year ago with Android 5.0. Make no mistake, this is not Google or Samsung preventing you from rooting... it is all down to your carriers, AT&T and Verizon.

This post appears to be from a reputed member of their community, so we can be reasonably assured that even the great people at XDA-Developers (AT&T SGS5 thread here) have not managed to root this particular device (see here).

Hence, we can say that as of now there is no way to root this particular device (AT&T Samsung Galaxy S5) on this particular Android version (5.1).

Outlook Calendar on Samsung Galaxy S7 will not sync

In the hope that this will help someone else.

Uninstall the Outlook app
Go to "Settings" > "Accounts" and remove all accounts relating to hotmail.co.uk
Add a new "Microsoft Exchange ActiveSync" account and enter your details.

Once successful you can view your email by using the pre-installed "Mail" app and you can view your calendar entries by using the pre-installed "S-Planner" app.

If you want to use the Outlook app then follow these further steps

Reinstall the Outlook app
Open the Outlook app and follow the instructions in the setup wizard. Choose "Exchange" account when given a choice between "Office 365", "Outlook.com" and "Exchange".
You'll have to enter your username and password several times and accept all permission prompts.

You should now be able to see your calendar entries in the Outlook app.

(strictly speaking I don't think you need to do step 3 if you carry on doing steps 4 - 6, but I'm not prepared to go through all that again to prove it)


Can an app installed from Play Store being dropped support due to changing requirement in Android version?

App developer (free/paid app) is at complete liberty to support/not support later Android versions, with or without continuing support for earlier versions. You will find many apps not supporting Lollipop or Marshmallow, and on other hand supporting/not supporting earlier versions.

Developers have two choices (nothing is binding), as cited Support Lower Versions of Android as an example, relating to autoback up feature of Marshmallow:

Updating an existing app to support auto backup.
Giving your new app support for lower versions of Android

Google Play Store policy doesn't discuss this, so only inference is that the app will be on Play Store:

As long as it complies to Play Store policy
As long as developer wishes

  developer decides to drop support for this old version, does the Play store offer an option to refund the payment?

No refund is possible. See this answer for details and also read the comments, which relate to your question If a paid app stops working, can I get my money back?

Edit: An important point of compatibility pointed out by Izzy. I have a paid call recorder app bought 4 years ago, which worked fine but is not compatible with  current Huawei phone and developer can't fix it since information about chip set (Kirin ) is not made public by OEM. I can't obviously ask for a refund


Accidentally hit PIT during Odin update now phone is stuck

Well, you seem to have 2 options:

If under warranty, send it to service center, your Main board (PBA) should be replaced.
You probably will need a JTag repair!

AFAIK, there is nothing you can do at the moment, by yourself to get the phone working, apart from the options mentioned above!


Go to quarx2k.ru, and select one of the 2nd-boot folders. These work for both MB525 and MB526. Simply download and flash, making sure to wipe the system, data, and cache first. If you want google apps, go to goo.im and select 4.2 or 4.1, depending on what version works.

If you want a really stable version, select 4.0 or 4.1.
4.2 was not developed on very much, but 4.3 works, I use it daily.
It's not completely stable, but certainly usable.
4.4 works, but I really don't recommend it as of yet.

Hope this helps, message me if you want more information.

It may mean that your contact is using a privacy option to keep that information private:

https://www.whatsapp.com/faq/en/general/20971848

"Through our privacy settings, you have the option to control who can see your last seen."

There are a few reasons why you may not be able to see a contact's last seen:

They may have set their privacy settings to hide this information.
You may have set your privacy settings to not share your last seen.
If you do not share your last seen, you cannot see other people's last seen.
You may have been blocked.


How to read Exchange e-mails on Android?

You don't mention which phone or Android version you're using. On my Motorola Droid (Android 2.2) the built-in E-mail application allows me to connect to my employers Exchange server. When I created the account, I had three options for connecting: POP3, IMAP, and Exchange.

There are other e-mail clients out there that may also connect to Exchange.


I don't know exactly what was wrong, but it seems to me that whatever the problem was, it w had something to do with a permission in /data as when I wiped it, it worked as expected.


How to check version of OR update the flashplayer on HTC Android phones?

You can install/update the flashplayer from the market. Just search for "flash player" and the one from Adobe should show up first.

To find out version go to: Settings > Applications > Manage applications > All > Adobe Flash Player. In there it should list the full version.


Are there any distributed-computing Apps for Android?

I don't think so.  While you're ( they're ) on to something with the high amount of untapped CPU cycles accessible via Android ( and other mobile ) phones - the limiting factor tends to be that users don't want their batteries drained to compute fractals ( or something of the sort ).

If you were to create a service, however, that worked ONLY while the phones were charging, that would be a completely different matter.  However, doing so greatly reduces the time that would be available to tap those CPU cycles.

[Edit] - And further notes...

At one point I had investigated ( fairly heavily ) creating a distributed database system that would reside on mobile phones to support basic Apps that didn't want to rely on a REST service.  Ultimately, it came down to the lack of unlimited power that made it not worthwhile.  The goal still seems a bit of a holy grail in mobile application programming - create a distributed system that can take a service and database schema, and then add in a discovery and hash system to keep track of live nodes that had data.  Moving all of that information around could bog down a 3G connection - but a few years from now that won't be much of an issue I think.

If this is what you are referring to, it appears to be notifying you of a network extender that your phone could be using to get better signal wherever you are.

Even if you don't have network extender, your phone could be connecting to someone else's that is on the same network (Verizon, AT&T, etc.).


How can I access Internet using my PC through an Android phone connected via USB?

Seeing that you have 2.2, the easiest solution would be to go to Settings -> Wireless & networks -> Tethering & portable hotspots. There you have an option to enable usb tethering (exactly what you asked for) or, even better try out Portable Wi-fi hotspot. That way you will be able to connect to the internet without connecting the phone via usb, and connect multiple devices if you want.


Does an adblocker defeat the tracking part of the ad module, or just the display of ads?

tl:dr;

Tracking can be done by an app without showing ads. By merely blocking ads you are not preventing tracking
Hosts based ad blocking is better than browser ad blocking, since it does not reveal PII (Also see Izzy's comments) Browser based adblockers can track as shown, so it is a privacy risk
To  prevent tracking , ad blocking needs to be in conjunction with other methods of plugging Privacy breach or PII breach. The only tool available is Xposed module XprivacyLua for Android 6.0 to 8.1. It is a successor of Xprivacy module that runs on earlier Android versions

  I'd like to know if the usual ad blockers on Android do anything to prevent user tracking from ad modules

What is user tracking ? This needs to put in context first.  It can be anything that fingerprints an user  for instance (Also, see this article from Izzy's blog

Network Information

WiFi you are connected to (SSID)
Country network identifier, telecom operator you are connected to,

Device Information

Device information – Build Properties

Device build user,  build type, build time, build  tags, build serial, build radio, build manufacturer, build ID
Advertising Client ID
Google Services Framework (GSF) ID
In case of web browsing more information – see Browser leaks and Webkay
Analytics (Fabric/Crashlytics, Facebook app events, Firebase Analytics, Google Analytic, Mixpanel, Segment)

This list is illustrative and not exhaustive . For instance, SIM information, IMEI information, Sensors on the device etc may also be used. For more details on other  privacy elements see XprivacyLua Github

Now, coming to specifics in your question . As you rightly surmised Hosts file based ad blockers just do that, block access to listed domains and are more effective than browser based adblockers as you can see from iBug’s answer and Izzy’s comments

So if your primary aim is to block ads is the way to go compared to browser based plugins, which may leak PII information (It does leak in the case of Ad Block Plus, haven't tested others)

But the question to be asked is  Am I stopping being tracked? for which the answer is emphatic NO , unless you use tools in addition to prevent privacy breach and this is where XprivacyLua comes in

  If I use Ad Block Plus (with no whitelist), AdAway, uBlock Origin within Firefox, or other popular ad blockers, do these do anything for the ad modules in the OS/APK from sending private data to the ad networks and/or app developer?

NO, in the case of Adblock plus

I am not discussing the relative merits partly because I haven’t used them all and partly because it is secondary to the thrust of my answer. However, I installed Ad Block Plus and restricted exposure of  elements that facilitate fingerprinting, as an example

Screenshot below shows the actual values and the values exposed to the outside world to prevent breach. For instance the first shows the operator information as 40445 (no secret here) and what is revealed is 00101 and the last shows while I am using a Xiaomi device , make is not revealed ( I have chosen specific portions of log (needs Pro version) which anyway don't reveal too much). So Adblock plus is revealing all your build properties!

(Click to enlarge)

In addition it is also revealing your Android ID, advertising ID, GSF ID as you can see from the notification

(Click to enlarge)

So, you set out to block ads and while doing that revealed information that can be used to fingerprint you :-(

To sum up you need a wholistic approach to guard your privacy and the best available for that is XprivacyLua

Please note that while this module is very powerful, it has certain limitations like restricting access only if the app uses Java Code and not native code or restricting tracking on browsing if Webview is used and not a browser like Chrome. That said, it’s the best weapon in the arsenal to protect privacy. In addition to the hooks (restrictions) provided by the developer others have contributed custom hooks and being open source you can write / modify your own hook. To top it, the developer is ever available and responsive on the XDA threads


You can periodically check status of real connection using HTTP GET by Tasker. You can restart the Data again by Tasker in case connection is stalled.

But, its down side is that it'll drain battery faster.


USB Error after failed attempt at flashing

Answering my own question:  I fixed it, and I'm not sure how.

I did several things, and I did them several times. Can't tell which thing or combination of things worked, but here's what I tried:

Removed the sd card.
Connected the phone to the pc without booting the phone. This took it into Recovery mode, sometimes but not always, and I didn't figure out why sometimes it went into Recovery mode and sometimes it didn't. From Recovery mode, I selected and ran the Factory Restore option.
Removed the battery and left it out for several minutes. (I kind of think this was important.)

Eventually the USB error vanished, Odin discovered the phone, and I was able to reflash the stock ROM.


How do I replace the default messaging icon in the dock with handcent?

Assuming you are using the default Samsung TouchWiz launcher:

Open the App Drawer (Applications)
Press Menu, select View Type -> Customizable Grid
Press Menu, choose Edit
Drag off the Messaging icon, and drag on Handcent.

I've replaced it with Gmail, myself.


Verify the photos are on your google account by going to https://photos.google.com. (sign in if needed) then verify they are there.

If they are then:

Go to accounts and sync.
add account.
allow 5 minutes to sync in background.
open accounts and sync and sync now by hitting menu or 3 lines/dots and hitting sync.
Update/install google photos app and then open it.
change account under the google photos app to correct account if needed.
See if photos are there, if not, after checking wait 3 minutes and check again.

Another option is too use the website to download all the photos to your sdcard by clicking on the "photos" section and then hitting the 3 dot menu in top right and hit "select photos", select the ones you want, then 3 dot menu again and hit download photos.


Can I bypass the Google Verification on my Huawei Mate 8?

Pretty much every phone can do factory reset while turned off, try this:

Turn off the Mate.
Press and hold at the same time: Volume Up + Home button + Power button, until you see Huawei logo.
Then select from Recovery Mode menu “wipe data / factory reset” using Volume buttons to navigate and Power button to confirm.
Select “Yes — delete all user data” to confirm the whole operation.
After that select option “reboot system now”.

Video streaming among Android devices using Wi-Fi without Internet

Your best bet would probably be using a DLNA server app (This one, for example, though there are lots of others) on one device and an appropriate player (example) on the other devices.  Not sure if it would work over a hotspot tether though, but there are free apps available for both ends, so it can't really hurt to try.

EDIT: Oh, misunderstood the question. That's about as easy. There are several apps on the store for running a camera server, like this one, for example. You then can use any compatible player to connect and view the camera feed


Why is rooting considered dangerous

Because when you root your phone you have (basically) full access to your phone, if you accidentally delete a system file/application it can brick your phone & you have no way to get your files back unless, of course you have the stock firmware downloaded & restore your phone using Odin.


Galaxy S7 stopped working - Want to retrieve files

Are there any torrent clients allowing you to choose one file from a list?

I use aTorrent, which has the possibility of selecting which files to download. Just change to the File tab and use the checkboxes.


First you need to factory reset your device from recovery.

Download GApps from xda-developers. (You need to search it xda). Download pico or mini version of gapps.

Copy zip file on your device and flash it via recovery.

Mostly, this will work. If not, then try to switch from dalvik to ART or ART to dalvik. (This applies only if you have 4.4+ Android OS)


In ICS 4.0.3 using ADWLauncher EX, how can I make only three home screens instead of five?

From the Homescreen, go to Menu, then Edit. This brings you to an overview of configured home screens. Long-press the one you want to remove, and drag it to the trashbin which appears. Continue until only 3 screens are left.

Similarly, if you want to add more screens, there's one "screen" with a plus-sign ("+") in the same place. Tap that one, and you'll get an additional screen.


So the answer to the question is to use ports above 1024 or as @Izzy suggested to ask the dev to implement root access (as an app must ask to perform root operations, simply "granting it permission" would not help as the app would not know to (properly) make use of it).


Why do I need to remove my battery periodically to fix phone problems?

It's not the battery retaining state, it's the phone circuitry retaining state. Even when you use a "power off" command and your phone looks powered off some of the circuits will still be connected to the battery so that the phone can be turned on by just pressing the button. So there will be some circuitry powered on even after the phone was "powered off".

This is likely a bug in the circuitry. This actually happens to devices - you sometimes need to "power cycle" them by unplugging them from the power source and then plugging them back. In case of a mobile phone that requires removing and then installing the battery.


Answering own question in case anybody else has the same issue.

There is another file /system/usr/keylayout/Generic.kl that contained the mapping for the power button. The Android docs say never to modify this file but I did anyway. Commenting out the power button line in this file has solved my issue (power button stuck in) and I'm now using my volume up button as the power button.

Note that I also had to remount the /system partition as read-write that I did with the excellent FX app


You seem to have downloaded the wrong ROM, if you are 100% sure this is the correct rom it might be a bug in TWRP.

You could possibly try to reinstall TWRP like this:

Download latest TWRP for your device (you already have)
Copy it to phone via OTG or SD-card
Select 'install' in your current TWRP
Select 'image' option
Choose the TWRP image file
Select the type 'RECOVERY' when prompted, and flash it.
Power off from recovery and boot it into recovery again and try to flash the ROM again.

Another thing you can try is wiping:

Boot your device into recovery mode
Select 'advanced wipe'
Check 'cache', 'dalvik cache', and 'data'
Wipe

Then after wiping try flashing the ROM again.


How can I keep track of all types of contact interactions in one place?

One way to do this would be with Evernote.  You could organize it all sorts of different ways (eg. Organize companies by tag or by notebook... and a new note for each interaction...) and you can attach files (photos, pdf, voice memos...) to each note.  As far as recording the actual calls, as Matthew Read suggested, take a look at this question.

If you are looking for a more integrated approach that works with the current call log and calendar you could consider an app like BizLog ($9).  It doesn't do everything you want but it gets you very close.  If this is more of why you are looking for I'd continue your search but use terms like CRM (contact relationship manager) and contact notes, contact log or contact management.


Google maps navigation doesn't stay in status bar anymore

I had notifications disabled for the maps app. :0

The app still closes when i press close all apps. Don't think it used to do that earlier. But at least I can switch to it easily.


Could you ask your ex-wife for the password? That would be the easiest way.

If that doesn't work, you could start a password recovery procedure on a PC, in some cases it uses a registered Android device to verify ownership, which you have access to. Just click on the "I forgot my password" link at gmail.com.

Sadly there is no way to transfer paid apps and in-app purchases between Google accounts.


How to create app-like Chrome shortcuts?

You wait for the web app developer to implement Chrome's WebAPK on Android feature/requirements.

From the following post: How to Remove Chrome Logo from PWA App Home Screen Link (Android O Preview)

Digging through the comments on the accepted answer from Anand dated Dec 17, 2018:

  If you are asking how to avoid chrome icon, as long as your went [sic] app is fully qualifies PWA to be installed as APK, new versions of chrome won't add that icon. I've tested with chrome version 70 in Android pie . If it's a mere web page, failing to meet key PWA criteria or non PWA, chrome might add chrome icon to indicate it's a web link(depending on chrome version again)

Further research on details led me down a rabbit hole of what features exist on Chrome vs Android and the meaning of 'install' to home screen, which while it does somewhat affect end-user behavioral expectations, the implementation details are off-topic for this site.

If you can live with icon badging, you may want to try your site/webapp with Firefox for Android and see if the app UI still retains the undesirable "header".


How to replace the generic Google TTS service?

Ivona voice sounds the best hands down (especially Amy and the new not yet on Android Salli voice). Works great on all apps for me. Sadly, whenever I reboot phone, Ivona no longer works. Only fix is to reinstall the whole thing which is a total PITA. I still do it though cause it sounds so much better then any of the other choices.


Wireless Charging stopped working; Could it be a software issue? (Samsung Galaxy S3)

Oddly, my receiver (NillKin) stopped charging the phone on the same day as yours did.  I have a Pixel XL (Android 8) & this solution worked great!  ...until it didn't.  Try turning the phone off & see if it will charge. Mine still will, but only if turned off.  I do notice that I have to be more precise with placing it on the pad than I used to.  Only thing I can think of electrically that matches the symptoms would be if there are multiple wires used in the loop & one is either shorted or ground.  ???  Anyway, I ordered another one that should be here in a couple of days.


Deny the installation of apps or add new accounts (kiosk mode)

SureLock promises this amongst others, see its entry on Google Play.

With Android's rapid development, this is however a rather quick moving target.

I suggest you search also for 'android kiosk mode' on Google or of course in the Play Store.

Besides this: There's already a question for that on stackoverflow:
Kiosk mode in Android


Who are responsible for pushing out the OTA updates?

If your handset is Google Nexus, then yes, Google pushes out the OTA updates.

The rest is down to the carriers, depending on who you are with, what handset you have.

Edit: Added more thought for clarity.

Some may not roll out the OTA updates, its all dependent on the market, region. I am with O2, and never get any OTA updates what-so-ever. Some manufacturers do include a 'PC companion' suite that accompanies the handset  and it is through that pc companion suite, that there may be a "firmware" update that is independant of the carrier used. That would be an exception to the rule, although the trend seems to be, to "use the official manufacturer's handset companion software for Windows" and to check on that regularly.


ADB is able to work over Wi-Fi, but it needs to be enabled on the Android device first.  Usually this is done by using command adb tcpip 5555 while the phone is plugged in via USB.  However if the USB port is damaged, you will need to be rooted to enable the wireless adb mode.

If your phone is rooted, connect it to the same Wi-Fi network as your PC,  install a Terminal Emulator app, open it and run the following commands:

su

Accept the prompt to allow access,

setprop service.adb.tcp.port 5555
stop adbd
start adbd

If the above succeeded, you should then be able to connect from your PC by using command adb connect <IP of your phone here>, for example adb connect 192.168.1.100.  If successful, you should be able to continue debugging.


As of version 4.3.10, the Google Play Store now has a "Recently updated" section under "My apps", which is ultimately what I wanted.


The Short Answer

Nope, not possible, or at least compicated & tedious, because Android defaults to WiFi since it's generally faster, more reliable and has no data cap

However

You may want to look into this app. While it requeires a rooted device, it allows you to leverage on both your WiFi & 3G to download at the same time.

The Long Answer

As t0mm13b has suggested (and I eagerly defer to him), if you're really serious about this and have the necessary expertise, you can

  modify the source code to remove the mutually exclusive flip/flop and also at the RIL layer

Unfortunately, I'm not qualified enough to do more than point you in the direction of the Android Developer Page if you decide to go down this route.

How can I share my current GPS location from google maps?

Here's what I can do on the current Play Store version of Google maps. (9.22.1)

From your screenshot, it appears that your GPS position is not accurate. In "location settings", choose "high accuracy". Get out where there's no concrete roof above your phone.

Let GPS get a good fix on your position.

Zoom in on the screen. Press and hold on the "blue dot" for a menu to appear with details of the location.

Then click the "share" button.

Choose "copy to clipboard", if that's what you want. Else choose an app to share your location info.

What file systems can I use for a 128GB sdcard on Android 7.1, used as portable storage

If 'journaling' is a requirement, then the EXT family (preferrably ext4) mighy be your only choice. Otherwise exFAT is the best. Just FYI, data safety depends more on your hardware rather than software (assume there's no malware), including filesystems. Any FS on a bad drive fails, and any FS on a good drive makes few differences.

It is definitely sure that if you format it to ext4, you'll have to frequently chmod -R 777 and chown -R 0.1028 (which is actually root:sdcard_r) to ensure apps work fine. Different apps have different UIDs & GIDs and upon creating a file, the owner groups are set as the app's U&G, while permissions are set according to the effective thread's umask.
Another notice is that Linux ACL is not supported by Android, whereas SELinux is, which can cause.
The FAT family is better for not having permission support, thus preventing "permission chaos" from happening. exFAT is my personal preference for shared storages. There's no regular maintenance required.
Since you're asking here, an Android community, I'm not going to discuss NTFS & Apple's HFS as they can hardly be recognized by a common Android device. Of course you can add the support for those by yourself, but it's mainly a concern of developers.

Is there an app like ROM-control for non-AOKP roms?

The answer is no, you cannot, because ROM Control is an app that is geared and orientated towards Android 4 and in this instance AOKP, hence internal API's are different. Back porting it into a non-ICS/non-AOKP ROM may fail due to the dependencies on the aspect of AOKP, such as settings, and ICS internals are vastly different to non-ICS code.

If you are a programmer and like to torture yourself with the challenge of it, then maybe its possible to back-port certain aspects and build the ROM yourself.


Where are contacts located on Xperia P internal storage?

You need a phone with root access. The folder that usually stores the contacts is data/data/com.android.providers.contacts/databases/contacts.db As  you would imagine they are placed in a 'safer' part of the device storage.

However, the /data folder is accessed via root directory /

You can root the device or you can use a Contacts Contract to access the database programatically, but as a normal user you can't.

As noted in the comments /android/data is not the same as /data

But you should wait a little, maybe there is a objection regarding my statement.


Samsung Galaxy Note 3 won't sync with google play

Here is what Google Suggests to sync your phone:

Change date & time settings

You can try to force sync your account by manually resetting your time settings.

Open your device's Settings app Settings app.
Tap System and then Date & time.
Turn off Automatic date & time and Automatic time zone.
Manually change the date and time so that both are wrong.
Tap Home Key.
Open your device's Settings app and then System and then Date & time again.
Manually change the date and time so that both are right again.
Turn on Automatic date & time and Automatic time zone.

(Excluded 'deleting and re-adding your account' here as you already did this.)

Here are all possible options available by Google Support: Fix account sync issues

Google Play Store

In case you don't have Play Store App, you can download it from apkmirror , choose a version and install it after downloading.

You will be ask to enable 'Unknown Sources' to be able to install Google Play Store, follow this to enable:

Open Settings - Security Settings.

Scroll down to 'Unknown Sources' check the box.

After installing Google Play Store successfully, uncheck the 'Unknown Sources' box.

This will prevent everything (except the Play Store) from installing apps.

Turn off the notification sound at system level - Android Marshmallow

Automation is the preferred option. Many apps are available. I prefer using MacroDroid , since it is free (upto 5 macros) and easy to learn. To understand how MacroDroid works and required settings,  my answer here

Your macro would look like this

Macro : Kill Notification (name of macro )

Trigger:  Application Launched ( choose from the drop down the apps for which you want the macro to run)

Action: Notification Sound  ( select none, since you don't want any)

Constraints: None ( which means this macro always runs whenever chosen apps are launched)

Why can't the Droid 2 connect to 5 GHz WiFi networks?

The WL1271 WiFi chip in the Droid 2 does not support 5.0 GHz networks, so there's sadly no possibility of a workaround.

I it necessary to SIM unlock my Samsung Galaxy S2 to use a custom ROM?

What does "Device connected - Updated usage information for some apps" mean on Play Store?

You probably share usage and diagnostics information of that device with Google. In this particular instance, It means that Google Play Store was connected to its server and as stated "Updated usage information of some apps". The information can be when last you used the apps, how long, etc.


Practically all mobile phones are using the Google Contacts app to manage your contacts. They create a backup of your contacts to the Google, and continuously synchronizing with it. This is why you can see the same contacts on all your Android devices (if you have multiple).

If not this is the case on your phone, you need only to install the Google Contacts app.

If you don't want to share your contacts with the Google, there are also many third-party apps to save them to other cloud services, or to your own machine. You can find them quickly with Google searches :-)

Having your contacts saved with an app, your contact list will survive a factory reset. Note, there is a high chance, that it won't fix your problem. In my experience, such sudden wifi disconnections root probably in the bad hardware/driver, or in some overloading of your device by the recently hugely grown apps. If you have no better option, it surely worths a try.


Take a look at this video LG G4 Proximity Sensor Calibration (No Root,No App needed) - YouTube.

Go into the secret menu of the phone and do as explained in the video. It worked for me. Good luck.


How can I unlock my HTC One V locked by 3 (UK Carrier, www.three.co.uk)?

Your local independent phone repair shop or market trader will probably SIM-unlock your phone for around a fiver, or you can probably negotiate it as a free service if you're buying something else there. It's not quite free, but if you value your time at all, it's probably cheaper than faffing around trying to do it yourself.


What is the difference between AOSP and CM/AOKP?

Well AOSP [pure android from google's kitchen] is the Android Open Source Project which is the father and the mother of all ROMS out there, it is the base android code.

AOKP is kanged [copied/stolen], its based on AOSP or derived from AOSP with some mods.

Differences are mostly UX and UI based, for example HTC Sense and Samsung TouchWiz are all just skins on top of pure android. Ok not pure android there is a lot of stuff modified by the big banners. The basic idea is this, AOSP is what google gives and AOKP is what people build with features on top of AOSP.

EDIT : XDA-Developers
The above mentioned thread has a lot of info if you the patience to scroll through!


in my opinion the preferred way for extracting such backup archives is Android Backup Extractor (abe) (requires installed Java Runtime).
It allows to convert adb backup archives to tar files and also the reverse way to convert TAR files back to an adb backup files that can be restored via adb.

Can I remove the .nomedia file from Google Music downloaded music folder?

The .nomedia file is for the reason you stated. You can safely remove the file and other apps will be able to pick up the medias in that folder.

In any case, if there is any problem you can easily create that file again. It can be a empty file with the name .nomedia. You can use programs like ES File explorer to explore to that directory and create the file.

EDIT:
As per the comments below which contains very useful information:

Your Music apps may recreate the .nomedia file when you launch it.
Other players will only be able to play the music if only the musics are DRM free.

I dropped my phone in water and now the screen isnt working - i cant remove the battery

The first thing you should do when dropping a phone into water is switch it off immediately and make sure it's completely dry before turning it on again. Keep it inside a case of rice so that the rice can soak all the moisture from the phone. Keep it inside for a day or so and try turning it back.

So try doing it now and hope it works else you'll need a new phone.

Icon is stuck behind google search, and appears on all screens (screenshot included)

Note that my other answer is more of a workaround (but also something recommended by many even without problems) that is almost guranteed to fix the problem. This is a direct fix which will most likely work, but I can't say that with absolute certainty as I can't recreate the situation myself.

After some googling, I've noticed that your icon (as you point out already) is off-center and missing its text label. Rather than the icon itself being stuck, it looks like what you're seeing is a stuck graphical artifact. This has happened to a few other users on other forums, and rebooting the device seems to be a fix for them.

Whether this works for you or not, I'm posting it as an answer for the sake of future internet travelers who stumble upon this question.


Note sure if this question should really been have migrated here. But this is a typical case of a vacuum that we have here. It's not really an android end-user question and on the other hand not a android programming question.

Anyway it looks like a typical codepage/localisation problem:

"<" on an US layout is ";" on an German (and maybe others) keyboard layout
">" on an US layout is ":" on an German (and maybe others) keyboard layout

I take a wild guess and say that you develop under Microsoft Windows, where each windows can have a different keyboard layout. You should see a symbol with the current layout right to the clock in the taskbar, where you can change this.

I hope I was able to point you into the right direction.


How to make packages from f-droid to be treated as from a "known source" (if I have root)?

Almost every F-Droid app is signed with a different key, though all keys are in the same key store. In order for the switch to be bypassed, F-Droid client would have to be installed as a system app and made to work safely as such. Some code has been supplied for this to work, but it hasn't been integrated yet.


is it possible to use a CA-Cert for serverauthentification in WPA enterprise networks with android 2.2+?

At least on 2.2.1 I can see the options to use certificates. First you have to install the certificates by placing them on your sdcard and using Settings -> Location and security -> Install encrypted certificates. Then you can add the network from Settings -> Wireless and network -> Wi-Fi settings -> Add Wi-Fi network. Select 802.1x EAP as the security mode and then just configure the settings to work for your network. Can't test myself since we don't use WPA-Enterprise class security, but it should be this straightforward.


Auto-Enhance Multiple Photos In Gallery?

There is a fairly new app called Perfectly Clear which allows you to select multiple images and apply corrections to all of them at once in batch. You could also set a preset and apply the enhancements the same way for all images. Fair warning, for the more advanced features they have in-app purchases.


How can I find out which app is putting ads in my notification bar?

One way is to find by log.
If you have android sdk installed,
run

  adb shell dumpsys notification

The output will have details about all the notifications. Using Package name you can get the app that has been pushing ads


What private data can apps access without any specified permissions?

Will bootloader unlocking provide access to all the apps in the Play Store?

No. Unlocking the bootloader will do nothing for Google Play. Even rooting won't do anything by itself as far as phone compatibility goes.

To get access to the apps without device restrictions, you must have a rooted phone. You then must edit the build.prop file to change your phone model to one that can install the app in question. See this android.se question.

To get access to the apps without country restrictions, no root is needed. You must instead have a proxy whos IP address is inside the particular country desired (generally the U.S.). Or you could create an account via a U.S. proxy on your desktop, then push the apps to your linked device despite it's out-of-country location (see this explanation). Alternatively, you could have a rooted phone and download Market Enabler.

E:failed to mount /cache (invalid argument) - how to format?

How to do a factory reset on Samsung Galaxy Tab Pro 8.4?

So the only way I could resolve the issue and reset my tablet was to install CWM recovery (the last working link I found). I believe stock recovery would work as well, but I didn't have or find one.

The second step is to go the Settings → Backup & Reset → Factory data reset and clicking "Reset tablet". It will warn you about unavailability to backup or recover your data since device is encrypted and then will reboot device to recovery and provide factory reset.

Again, it would probably not be a problem if I'd have stock recovery. But in my case this was the only way to provide reset for my device and it took some time to find this out.

I also could try using restoring stock ROM with Kies or Odin, but I didn't have a working copy of Windows...

BTW here a few different ways you could try for other devices:

If you know your password or you have a stock recovery it should not be a problem at all - just use the default way to wipe your data (through recovery or android settings).
Use fastboot erase userdata (it didn't work for me, because Samsung has no fastboot mode, they have their "Download mode", which is a bit different)
Probably there is a way to reset/recover your device through some vendor provided tools (like Kies/Odin for Samsung devices).
You are so unlucky :(. Try to search about how to do factory reset for your particular device.


I didn't look back through older versions, but here's information accurate as of Android 7.1.2.

The code that performs the transformation from RSSI to signal "level" is found in the WifiManager.calculateSignalLevel method:

public static int calculateSignalLevel(int rssi, int numLevels) {
    if (rssi <= MIN_RSSI) {
        return 0;
    } else if (rssi >= MAX_RSSI) {
        return numLevels - 1;
    } else {
        float inputRange = (MAX_RSSI - MIN_RSSI);
        float outputRange = (numLevels - 1);
        return (int)((float)(rssi - MIN_RSSI) * outputRange / inputRange);
    }
}

...where MIN_RSSI is -100 and MAX_RSSI is -55 (source). The input range is "dynamic" in the sense that its based off of how many resource files are available for the WiFi icon, but in AOSP this value will be 5 because it has icons for 0-4 bars. Using the above logic and values, the ranges come out to approximately:

-55 or higher: 4 bars
-56 to -66: 3 bars
-67 to -77: 2 bars
-78 to -88: 1 bar
-89 or lower: 0 bars


Anki - Next card review in <-36.2 years?

Solution: Date & time were incorrect on the phone when I was studying decks in AnkiDroid. After syncing to the correct time - AnkiDroid thought I've been studying a set of decks for years, not minutes.

Therefore, make sure your time is correctly set and preferably doesn't change to an incorrect value, otherwise don't use AnkiDroid when your date and time are wrong. Set correct date and time first.


Transfer data from one user to another in 4.3

Had the same problem with my kid's profile. Finally solved, but it required root access.

This is what I did:

Close all running app instances.
From command prompt start ADB shell:

c:\> adb shell

Switch to root user (your device must be rooted):

shell> su

Go to in target profile directory:

root> cd /data/user/[profile_user_id]

For example: profile_user_id is 10 for first restricted profile.
Rename app directory (to have a back up copy)

root> mv [app_dir] [app_dir].old

Copy app data from main profile (id=0) to new profile:

root> cp -r /data/user/0/[app_dir] .

Change owner for files just copied:

root> find [app_dir] | xargs chown [app_user]:[app_group]

Restart device (not sure if it is really needed).


From the picture it would appear you are correct.  Note #2, however.
The baseband is the modem firmware.


Let's take a look at the error message again:

Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]

This means that the app in question uses native C/C++ libraries, but the APK doesn't include that library compiled for the CPU architerchture of the the target device. Unlike Java, C/C++ code is not cross-platform, nor is it cross-architecture.

Some apps have different APKs for the different CPU architectures.

But, bottom line, this is the app developer's fault, not yours.

Removing an android app making troubles from Recovery mode

Try rebooting in safe mode. After getting the power menu, hold down on power off and choose reboot in safe mode.

You could also use adb commands found in this similar thread.

If you don't feel comfortable with that, you may have to do a factory reset.

Is there a way to download and store Google Maps permanently?

I use MAPS.ME as an alternative. It works perfectly offline, you can save places, search anything in the downloaded maps, and it has a router for driving and walking too. Its map data is from OSM. It is also accurate enough, (but) it can be edited by anyone, though this can lead to mistakes (I've not encountered any of them so far), and on the other hand, sometimes it is even more detailed than Google Maps.

Anyway there are a lot of apps on Google Play using OSM's data.


My take was to search for "keyboard"

Go to "Manage keyboards"

And activate Gboard.
Now I can simply long press "

And that opens up a modal with the « and ».


Phone Reboots on Installing/Launching Certain Apps

This could solve the problem temporarily. I had the same problem with my own phone and it appears to be a material problems, many recent updates are incompatible with some phones (it is the case for wiko phones).
Bypassig the play store and installing a previous update can work. For whatsapp you will need a previous version than the actual one (2.18.64), but that will be older than the 2.18.0, otherwise whatsapp won't let you start the app.

For example downloading this version and manually install worked for me: https://apkpure.com/whatsapp-business/com.whatsapp.w4b/download/164-APK

EDIT:

Now this version is considered obsolete by whatsapp too. The only way to continue using it for me was to set the date of my phone to a previous date that the date showed on whatsapp saying "This version of whatsapp is obsolete since date".

I hope this problem will be fixed later because it is unsafe to install previous versions, generally updates include bug and security fixes.


Install older version of apk on to newer installed version or root SH-06E 1.00.08

Your ending question differs in a little but significant point from your introductionary question. But let's go step by step:

Sure it's possible to install an older version of an app over an already installed newer version. For a user app:

make sure you've permitted installation from unknown-sources (see its tag-wiki for details)
open/launch the .apk file using a file manager, web browser, or similar
the package installer should fire, asking you if you want to replace the installed app by this "older version".

But be aware that though installation most likely succeeds, the app might experience problems if the newer version e.g. had updated the structure of its database (I had this only once yet, and the affected app just force-closed when trying to start it). If in such a case you insist on using the old version, the only way to make it work is to clear its cache and data.

Now to your final question. This is not just about installing an older version, but about signing it. Yes, that can be done as well. You've simply got to ask the developer of the original app to give you his signing key. Trouble is, his answer will (and should) be "no". Alternatively, you might give him the files and ask him to sign them with his key. Assuming it's the manufacturer's company behind it, the expected answer again is a "no", though.

So your real question rather reads:

  I've got an app already installed on my device. Is it possible to install a different (older) version of it which has a different signature – without rooting and patching system with Lucky Patcher or previously uninstalling the newer version?

The answer is: No, that's not possible:

Signature check will fail, so you'd have to uninstall the app first when using the "normal approach" as shown above
Overriding this signature check without root IMHO is not possible
Changing the signature to match IMHO is not possible unless you've got the developers key


Google Photos syncing stalled and draining battery

The Google Photos app updated this morning (21st July 2016 to version 1.24.0.127588984) and the backup/sync has restarted and is showing visible progress under "Assistant".

Boot loop after updating to official Android 6.0 Marshmallow on my Nexus 5

If your device is in a boot-loop you will not be able to pull anything.
You might want to try and booting the phone into bootloader IF possible by pressing volume down and power to power on the device.
I would recommend downloading the factory image from Google, extracting it and trying:

fastboot flash bootloader bootloader-hammerhead-hhz12k.img

To flash the bootloader image in in the zip via the command line, as well as boot and radio just to be safe. DO NOT FLASH userdata.img or cache.img, or run any flash all batch or script as this WILL erase everything that is currently on your device.

OR:

You can try to follow the same instructions to boot to bootloader and:

fastboot flash recovery twrp-2.8.7.1-hammerhead.img

To install TeamWin Recovery, which you can download here.
This will give you a custom recovery you can then boot to and possibly be able to adb pull from there.

Hope this helps!!


Does Huawei's super charging affect the battery?

Battery charging is an ongoing field. There isn't conclusive evidence that fast charging itself is bad. However, fast charging have a measurable impact on battery life in the field

https://www6.slac.stanford.edu/news/2014-09-14-study-sheds-new-light-why-batteries-go-bad.aspx
http://ecec.mne.psu.edu/Pubs/2018_Yang_JPS.pdf

Other variables include discharge rate or temperature also have an effect on battery life too. Like any engineering problem, fast charging is a trade off. The loss of battery life may not be pronounced as the normal 2-year life span usage rate.

Please note, fast charging is not part of the USB standard. Qualcomm, Huawei, Oppo and Apple create their own implementations.

Even worse, lots of cables break the USB C power spec.

I am not sure what will happen if you mix up different chargers.


I can't tell you if it's a good idea or not, that really depends on the type of user you are, but what I can tell is the following:

That feature's main goal is to improve some of Google's services, which means, you may get location based ads, and if you have Google Now, location based cards, among others. Besides, many apps use Google to retrieve your location in a more efficient way.

Now, if you are still concerned about your privacy, do not worry. You can always enable/disable it later. How? Well, it depends on your device's configuration, but I think it's pretty safe to say you'll find the option by opening the app "Google Settings" and then in "Location".


If I 'adb push' a file to /system/xbin, will it persistent?

Yes. /system is for persistent firmware files and will survive a wipe/reset unless you don't install another firmware (depends on the MOD's installer/installation script: some preserve other files, some do not).


Which method of wireless tether uses the least amount of power? Bluetooth or Wifi?

I decided to look up some data, and my guess seems to be correct: http://nesl.ee.ucla.edu/fw/documents/reports/2007/PowerAnalysis.pdf

According to the report, Bluetooth takes the least amount of energy.

However your 3G radio will probably take the most energy; maintaining a 3G connection without transferring any data is cheap, but once you start sending/receiving data, then it trumps even Wi-fi.

  WiFi radios have a high wakeup and
  connection maintenance energy, but low
  energy per bit transmission cost and
  high bandwidth.

  Cellular radios have low connection
  maintenance energy, but high energy
  per bit transmission cost and low
  bandwidth.

Disclaimer: The study might only apply for the particular model that the device they use.

Is it possible to successfully adjust predictive text for offensive words?

It seems that you can dis-associate the word from the phrase by deleting it as a suggestion. As per Get word suggestions & fix mistakes:

Get word suggestions & fix mistakes

On your Android phone or tablet, install Gboard.
Open any app that you can type with, like Gmail or Keep.
Tap where you can enter text.
Type a word. At the top of the keyboard, you’ll see suggestions:

If you see the word you want, tap it.
If you don’t like a suggested word, touch and hold it, and then drag the word to Trash.

I tried it out and I don't get the test word I moved to trash as a suggestion for the one that I dis-associated it from, but I still get it as a suggestion after other words.


I've recently used Kingroot, installed without computer assistance (downloaded the .apk with the device browser via wifi and installed from the device's internal storage), to root a device so obscure I haven't seen a single reference to any fixes, custom ROM, or even version upgrades: the Visual Land Prestige Elite 10Q tablet.  Kingroot took about ten minutes to run, including rebooting the device, and the only thing I don't like is that I have to hold the tablet in portrait orientation whenever I use any Kingroot function, because it doesn't recognize screen rotation.

Obviously, I haven't tried this software with a Galaxy A5, but it should be fine.


Yay!  Thanks to a lot of help from Izzy, I was able to extract the name of the launcher activity from Keep's manifest.  So that means that the console command is:

am start -a android.intent.action.MAIN -n com.google.android.keep/.BrowseActivity

It goes without saying to make sure to preserve proper capitalization (casing).  If you want me to find out the names of any of the other activities (so your command launches that activity instead of the main page), just let me know!


Backup is important

flash Stock ROM again.
Root the device, install a custom Recovery(TWRP), and install a custom ROM(Eg: Cyanogenmod or mokee or aicp etc) URL to XDA is descibed below :

XDA Zenfone2

How to Root and Install TWRP is described on this link.

How to flash:

Check for any firmware file required, before flashing ROM. Otherwise, your device will get bricked.

a. Install latest TWRP recovery on your device.
b. Make a backup of your current ROM.
c. Wipe system, data, cache and dalvik.
d. Flash ROM and Google apps.
e. Reboot system.
Custom ROM is installed.


When apps misbehave, usually clearing the cache or its data solve many issues. If the app doesn't contain important data, then try Settings -> Apps. Find it and delete its data. It should be reset as the first time you used it.

Then start it and set the settings to use it as before or change them for your new needs


Make sure that the SD card is mounted. If it was somehow unmounted this could happen. This option will be in Settings > Storage  scroll down to SD card. Make sure that it indicates that the SD card is mounted or at least doesn't say "Insert SD Card".

If it is mounted, unmount it, take it out, put it back in, and see if anything changes. If it isn't recognized, then just take it out and put it back in. Check back in with the details on how that goes.


Tar.gz not working (Segmentation fault) on ext4 partition

I still have no idea what is causing the problem, but I did find a solution / workaround, which does the same thing.

Instead of directly calling gzip from tar like so:

I pipe tar's output to gzip like so:

tar -cv directory/ | gzip > archive.tar.gz

and the segmentation fault is no more.


Can ROM APKs self-update without violating Google Play policies?

No and no. In the first case, the app isn't downloaded from Google Play, it's downloaded from another source. In the second case, it's shipped with the ROM, and has no ties to Google Play. However, if you supply the APK via other means than Google Play, you can't use Google Play's update features.


This seems the same problem these guys had solved in this 2 different 3Ds.

How to prevent Google from asking for location permission when enabling GPS?

How do you get ride of the pop up ?

Hi ,there is a simple solution go to settings > location > Mode and
choose device only , the phone will use only the GPS sensor to get
your location it is more than enough because any app that want to get
your location will get your Coordinates (X,Y,and altitude too -height
above sea level- )

What is causing the annoying pop up ?

The pop up shows up becuase you choose high accuracy when you choose
that option the phone will use ,your cell network ,wifi hot-spot and
GPS sensor to determine your exact location in order to do so the
phone need to send hotspot location or network antenna location.


How to fix instant lock “unfortunately com.android.systemui has stopped” on Moto G with ART

Sounds like an ART incompatibility. You probably installed an app recently that doesn't work properly with ART. Presumably it added itself to the start-up apps. That's why your UI crashes when booting up. You will have to find a way to either remove the app in question or go back to the Dalvik runtime.

I went through the same ordeal a month ago when I opted to try out ART. Of the various solutions I found on the internet only this one by androidcentral user sajidr worked. I'll quote it here in case the forum post goes down:

  I managed to switch my runtime back to Dalvik. It was painfully slow but in the end I didn't have to do a factory reset.

  There's a fraction of a second after unlocking when the screen responds to a touch or swipe. This happens only right after you see the error message popup - "Unfortunately, the process com.android.systemui has stopped". If you do not see this message after unlock then open up the camera from the lock screen & close it.

  Next, follow these steps to open up the app drawer -
  1. Unlock the phone
  2. Once you see the popup "Unfortunately, the process com.android.systemui has stopped", keep tapping on the area where you think the app drawer icon is. At the same time, using another finger click on the OK button of the systemui message box.
  3. If your timing's good then once the message box is closed, the app drawer should open.
  4. The phone would go back to lock screen but the app drawer would be open. You can validate this by unlocking the phone.

  Repeat the above steps to swipe over to your Settings app. Instead of tapping, do short swipes & then click on the message box OK button. Each time the phone would go back to the lock screen but you should be able to slowly navigate over to change your runtime.

  Once I got the hang of it, it took me about 15 minutes to go to Settings & change the runtime.

  Don't bother trying to uninsintall flipboard from your play store this way. I tried it twice & both times the phone rebooted itself after i clicked the uninstall button.

  If your screen layout shifts vertically after the unlock then tap on the area where you first see the icon & not where it moves to after the shift.

  Good luck.

Other users have had varying success with booting to safe mode and disabling ART / ART-incompatible apps from there.

it is possible, but you will need to get a root.
FolderMount allows to transfer not the apps but their cache. This program requires root access. If you don’t know what root is then go here and here to read about how to gain root access.

Cache transfer is performed in a few simple steps:

Open FolderMount and press “+” in the top right corner.
Name an app that has leftover cache in the internal memory.
Press “Source” and indicate the folder with the app’s cache. It is located in Android/obb/the folder with the app’s name.
Press “Destination” to choose a folder on the SD card for the transfer.
After every field is filled out, press the check mark in the top right corner and select the “pin” next to the Name field.

Switching app with physical keyboard, with one click "alt + tab"

the only way this works is as follows:

alt-tab, use arrows keys to select app and than press enter, once app has switched only than release alt-tab.

Hope this helps.


Streaming movie from Galaxy S5 to TV, through laptop?

I'm not sure you can because there are many interfaces in the middle. I don't think there's an app for doing that. What I strongly suggest you is buying the Google's Chromecast. With that $35 stick you'd avoid the using of your laptop and you'd stream directly to your TV.

There are a lot of apps for Chromecast out there, it's a whole new world because Chromecast is a whole new concept.

Videostream is one of the apps you can use for streaming from your smartphone or laptop directly to your TV (well, directly to your Chromecast, but it's connected via HDMI so it's the same) and controlling the play, pause, seekbar and even the volume.
