Why does my Samsung galaxy blaze randomly shut off and won't reboot until it is plugged into the wall? My galaxy blaze phone randomly shuts off (even though I have plenty of battery life left) while using it and then tries to reboot itself but never fully starts up. Therefore, it constantly keeps shutting off and on until I charge it.  While it is turning off and on I take out the battery for several minutes but nothing seems to work.  Once it plugs into the wall it starts to work again but lately this is happening more and more often, up to 5 times a day.

Would a new battery or update fix this or is it something malfunctioning within the the phone itself?

open setting choose backup and reset. Once that is done turn the phone on It should be as good a s new. I took this off T-mobile help thanks Tmobile


How can we trick an android device that the device does not get our real location? Is it possible to make the Android Operating System  receive false location data or not receive any data about our geolocation at all. And how we can do it in the  maximal clean way so that the third-party applications that are installed on the phone could't even suspect about it?

The phone has a GPS sensor and the OS can read the values from this sensor. Thus, the OS knows your real position.
However, the apps have no access to the direct OS reading - they can only ask the OS to give them the position. And the OS has builtin support to give them fake results.
To do that, do the following steps:

Enable developer mode (as described here).
In the developer mode, enable "Allow mock locations". This allows for apps to override the GPS sensor input by a fake position provided by them.
Install any app with exactly this feature, like Fake GPS Location.

It works a little bit differently on some phones, for example on my Moto G8 there is no "Allow mock locations" option in the developer mode. In most cases, it is possible even on them, but a little bit differently.
Extension: apps can know if it you did these, but they have probably no way to know, if the actual position they've got is mocked. Probably it can be prevented only by rooting the phone. Thanks @Robert for the info.


Phone changes timezone itself My phone is Huawei LUA-L21, here's the log from logcat:

Fixed it by creating small application which restores timezone every time it changes.

What type of headset will work for my Droid X? I'm shopping around for a nice pair of earbuds for my Droid X since I lost my other ones, and I was curious if I could get ones with a microphone to use as a headset.

What do I need to look for to make sure they're compatible?  Are all the 4-pin 3.5mm stereo jacks alike?  If it's iPhone-compatible will it not be with the Droid (especially ones with remote volume buttons)?

Any 4-pin 3.5 mm stereo jack should work fine for straight sound but headsets with controls are a little more difficult.  Many are proprietary.  If it claims to be universal it may work but if it's designed for Apple or Nokia it probably wont.

Basically, on a 4-pin jack it all depends on which ring the headset maps to which control.  I couldn't find a Droid X pinout diagram but I believe Motorola uses the standard layout.  This site has a pretty comprehensive list of the different pinout mappings and a lot of them are the same but a lot are proprietary.

If in doubt, I'd look for a set advertised to work with the Droid X.


Couldn't open connection to server I have a problem on Micromax Canves 2, and my colleagues experience the same. I don't understand why some times it works and some times not.

It works if I connect to WiFi. But not when I switch to my mobile network Internet. Then I get a message on outgoing server settings for my mail client: "Couldn't open connection to server".

Strange: when I used 2G network I was able to connect – but not when I switch to 3G network.

But now on both networks I am unable to configure my mail settings. This started after the Mail box password was changed. I have checked with my IT guy and all the inputs are correct and the new password.

Any suggestions how to solve this problem?

Some carriers block connections to TCP port 25 outside their own network. This is done to reduce spam, since that port is most often used by unsecure mail server default configurations. You should check with your IT guy if it's possible to use TCP port 587 with authentication.


Wifi WPA Enterprise - In android 11 under 'Online Certificate Status', what is the difference between the various options? Recently I noticed that my Note 10 would no longer associate with my wifi but all other phones would.  I have since resolved the issue by rerolling my certificates but cannot get the options 'Require status for all certificates' or 'Require status for untrusted certificates' to work.  'Request Status' does work as well as 'Don't validate'
'Require status for all certificates' fails with on the freeradius end with -

What do I need to implement or correct so these two options will work as well?

"Certificate status request" is the official TLS terminology for OCSP stapling.
The Android option is very likely a direct mapping to the corresponding wpa_supplicant option (just like the "Domain" field is domain_suffix_match, and so on).


Will an S4 boot and run without a volume button? I have a Samsung Galaxy S4 with a dented/stuck volume button (causing any attempt to boot to end at the screen that asks whether I really want to install a custom OS because the smartphone perceives volume down as pressed).

I am planning to dispose of that device after getting (read: copying and wiping) some data from its internal memory.

As replacing the button costs a lot (both at the official and at other repair shops), I am considering just removing the button.

Will the smartphone work (and keep working for an hour or so) without the volume button? I am wondering whether anything in the system will notice the button is missing and refuse to boot. Also, an employee at one of the smartphone repair shops I went to claimed humidity would enter the smartphone through the opening, and anyway, the repair shops outright refused to remove the button without replacing it1.

1: Presumably because then, I'd pay less. I will remove the button myself, if I find no-one to do it for money, though.

Yes. The phone can boot and run without volume button. You just have to make sure that neither volume down nor volume up button is pressed after removing the external button otherwise you may enter into recovery/Odin mode or into installing custom ROM mode. So remove the external button and boot up the phone as usual.


Why my phone is stuck on a backlit black screen? I have an Android phone, Lenovo vibe P1m. I had rooted it using my pc. One day I uninstalled SuperSU and tried to install Magisk. During this process, I don't know what happened but somehow the twrp recovery and the operating system got deleted. Then i booted my phone into recovery. Then my phone was stuck in boot loop. There was only a white screen with the brand name. After some days I tried to flash the stock firmware using sp flash tool on my laptop. When flashing was completed, I disconnected my phone from pc and switched it on. Now there is no white screen with phone's brand. There is only a black backlit screen. Now my phone has no OS, no recovery mode, nothing. Only a black screen. How to fix this?

Although I've never had a Lenovo device, I have accidentally deleted my OS and recovery before.

Are you able to boot the phone into 'Download mode' (I would love to post a guide for you but, after a quick Google I couldn't find one)?

Download mode should still be available (it's used by the manufacturers to install the OS in factory) and hopefully you'll be able to connect your phone to a computer and re-flash the firmware.


How do I mount a Kindle Fire 10.2.6 on my Linux computer? I just acquired a newish Kindle Fire, software version 10.2.6. Normally when I plug a Kindle or any USB device into my laptop (running Ubuntu 12.04) I get a popup screen asking me what I'd like to do and the device mounts. It has worked this way with 2 previous Kindles but they were software version 6.x.x.

So my question is, how do I mount this device so that I can move my books and files onto it from my computer?

I have ADB enabled and allow installation of applications from unknown sources. I don't have ADB installed on my computer because until now it wasn't necessary to move files back and forth in a Linux computer.

On the notification screen the Kindle says "connected as media device." I should also note that despite using Ubuntu I'm relatively unskilled when it comes to the terminal.

Summing up from the comments above...
As eldarerathis wrote: "connected as a media device" suggests it's using MTP, which would require special software to be installed (there are MTP packages available for different Linux flavours).
Try getting UMS working
You might also want to check your "notification area" when the device is connected: I don't know the Kindle Fire, but it might offer to switch to UMS (USB mass storage) mode. If you don't find anything corresponding in the notifications, also take a look through the settings. Just a possibility, nothing granted.
Try it with MPT utilizing the MTP file system
If you cannot get UMS working, there's a helpful link pointed out by eldarerathis is Connecting Google Nexus 7 to Linux on how to make mtpfs working on Linux. Basically, this can be done by issuing 4 commands in a terminal:
sudo apt-get install mtpfs
mkdir ~/NexusDrive
mtpfs ~/NexusDrive
nautilus ~/NexusDrive

Short explanation on what it does:

install the mtpfs package, which provides the MTP file system
creating a directory where to mount your Kindle to
actually mounting your device
opening nautilus to show the files contained

Of course, the last step can be replaced by opening any file explorer you like :) And as the "missing sudo" on lines 2-4 indicates, mtpfs is running in userspace.
Graphical MTP frontend
There's also a graphical MTP frontent available in the Ubuntu repositories: gMTP. It's mainly intended to be a MP3 player, but you also can manage your files with it:
sudo apt-get install gmtp

(it's in the universe branch, so you might have to enable universe first in your package manager)

(screenshots taken from LinuxAndLife)
So you could use this instead of Nautilus -- or next to Nautilus, depending on what you want to do. With gMTP installed, simply connect your Kindle via its USB cable, then launch gMTP. Click the Connect button then will mount the device, and the Connect button gets re-labeled to "Disconnect", as shown in above screenshots.


Does Samsung Gear S2 watch pair with non-Samsung phones? I know that Samsung S2 is a Tizen operating system but I don't know if they can be fully functional with Google or Motorola phones?

I currently have an app for Android Smartwatches and I'm considering on developing for Samsung Gear S2, but don't know if the work is worth the reward?

Yes, the Samsung Gear S2 is compatible with a lot of android devices.

The general compability requirements are:

  Gear S2 pairs with smartphones running on Android 4.4 and higher with over 1.5GB RAM.

Have a look at Samsungs official device-compatibility website.

Also quoting the Review of the Gear S2 by Techradar here:

  In the past Tizen has only been compatible with Samsung smartphones, greatly limiting their potential user base. Thankfully, the Gear S2 is compatible with any Android phone running 4.4 and higher with over 1.5GB RAM. I tested it using a Moto X Style and HTC One M8, neither of which caused any problems.

  Although almost all features are compatible with any Android phone, Samsung Pay is only available with Samsung devices. So if you want to pay for your groceries with your watch, you better get a Galaxy or Note (or an Apple Watch and iPhone).

  Samsung has also hinted the watch could work with iPhone eventually, but don't hold your breath.


Is "ROM" the same as internal flash memory? I saw the Nexus S storage specs are

512MB RAM + 16GB iNAND flash memory

and for the HTC Incredible S:

768 MB RAM and 1.5 GB ROM and microSD slot up to 32GB (8GB card included)

Is the Incredible's ROM the same thing as the Nexus's iNAND flash memory?

Yes, you can see here that the HTC's ROM is referred to as "internal storage" (although it says 1.1 GB): http://www.htc.com/www/product/incredibles/specification.html.


How can I tell what "Internal error" in Google Mail app For a couple of days now I've had error messages when viewing my mail in the Google Mail app.
In the beginning the error was displayed when loading mails further down the list.

By now I won't see any mails at all first entry is "Internal error"

Since these issues started the notifications of new mails has stopped working as well and I could not open certain mails (with and without attachments)

How can I get to the bottom of this?

Thanks, seb

It sounds like the database is corrupted.  I would go to Settings -> Applications -> Manage applications and clear the data for Gmail and Gmail Storage.  If that doesn't work, try clearing the data for everything Google (Talk, Google Framework Services, etc.).


Does cracked screen cause faster battery drain? I dropped my Nexus 5 a week ago and the screen cracked diagonally 8cm from side to side.

Since then I am sure that the battery drains faster than before. Previously I was always happy at how much battery life was left during the day, based on my experience of Nexus One and Galaxy Nexus. Now I am always noticing how quickly it is going down.

I didn't measure battery usage before the damage so I can't prove my suspicion. The battery usage settings screen shows the screen as the highest battery user, as before. Again, I'm sure the recorded percentage of screen battery use is higher than previously, but I don't have figures from before the break.

So, could there be a reason for the screen to use the battery more when it is cracked in half?

It could be that the visible crack isn't the only damage to your phone. If a connector is shorting in the screen or another component, that could be draining the battery (as well as generating heat).

A short could also cause sparking around the damaged component, which will cause further damage over time. You should get your phone repaired. If you tell the mechanic that you broke the screen by dropping it, they'll know to look out for other damage while they disassemble the device.


How do I change the default file association in ES file Explorer? When I click on a .bin file in ES file Explorer, the default action is to move it to the recycle bin. How can I stop this behavior?

I am on a Samsung S4 running Lollipop, TouchWiz ROM.
I have looked in Settings -> More -> Default Applications. This shows 2 options only  for 'Home' and 'Messages'.
I have installed the default app manager and there is nothing that relates to .bin files.

There is no file type association settings under Android so it's not Samsung's fault. ES File Explorer doesn't have an option to set a default file association but you can have the same result if you do the following.

Long click the item (file) you wanna open it will create a check list with the file selected.
Click on the three dots at the right bottom of the screen.
Choose open as then select what type of file is your .bin file (text,music,image,video or others). ES File Explorer will prompt a list of available apps that can open the file you wanna open, choosing other will prompt all apps that accept intent of any type of file. In that list choose the app that can open your bin file.


Local IP address of Android device connected via Ethernet I have an Android Tablet with Android 7.0 connected to my network via an OTG RJ45 Ethernet connector.

I know how to get local IP address when connected via WiFi, but not via Ethernet.

Any idea on how to do that (eventually with an app compatible with Nougat)?

Thanks

You can get the information you are looking for with the ifconfig command. On your android device install a terminal emulator app and open a local connection.

  The ifconfig is a system administration utility in Unix-like operating systems for network interface configuration.

connect and setup your Ethernet connection.
Open the terminal app.
Enter the command ifconfig into the terminal.
scroll down and look for eth0 or close to that.
You should be able to find the ip address there.


format and install new OS to get rid of viruses I have an android phone (my uncle's) that is full of viruses that display adds and reinstall themselves I'm guessing
there is no important/needed data on the phone

I tried factory reset, after used Dr Web to find viruses, and to root the phone (Kingo ROOT) in order to be able to remove some of them, 2 files identified by drweb couldn't be removed even though the phone was rooted because they were system files (priv-app/baseservice.apk and another one), I renamed them instead.

all this ^ didn't helped completely, they appear again somehow, so would like to format and clean install a new OS

is there a easy way to do that ?
my guess is I need some program on my pc (windows7) for this and connect the phone using usb and run some commands

the device is a fake galaxy S6, Android 5.0.2 kernel version 3.10.61

Things you can do:

Downgrade to your stock ROM and install a good antivirus and run a complete device scan because some of them are powerful enough to remove viruses from system files in priveledged user mode.
Install Ubuntu Touch instead of android as shown in this guide. The guide is actually primarily for nexus devices but you can make it work for Galaxy S6 by finding the stock ROM yourself and other stuff for the S6 yourself instead of following the links given in the guide which are for nexus devices.
If that doesn't work and you are unable to install Ubuntu touch for some reason try this.


Issues canceling downloads in Market All of a sudden a few days ago, I went into the Market for the first time in ages to download a new app. It said the app would be downloaded, but when I went back several hours later, it had not downloaded. I looked in the Downloads section of the market, and there were about 6 updates trying to download (which I hadn't approved - I don't have automatic downloads set, just notification of new updates with manual download). I want to cancel these downloads, but it will not happen. I long-press on the app name and choose Cancel, but nothing happens. I've even rebooted the phone, but the unwanted downloads are still there, saying Starting Download - this is after 3 days.

I've seen this, this, and this, but none of them are exactly the same as my issue. The last two did have answers that I'd like to try - clearing the application data and cache for the market. Unfortunately, I don't see the Market as an app in my Manage Applications section. (I'm running CyanogenMod 5 on a rooted T-Mobile MyTouch G3.)

Is there any way I can access that application to clear the cache? Or any other way I can get the unwanted downloads to stop trying and go away?

You can clear the Market data from the command line like so:

rm -r /data/data/com.android.vending/*


Solutions for connecting phone/tablet to a bigger monitor? An ebook I purchased is locked to my device so I can't open it anywhere else. I'm having a hard time reading due to the small screen size of my phone.

Is there a way I can get it to display on my monitor? I don't have any special cables so I'll have to use any wireless means possible. Also to note: I'm not looking for emulation as the app has locked my ebook to the device.

Any creative solutions are welcome.

You need to use the MHL Adapter Cable.

From the MHL Adapter, you can connect to any TV that support HDMI.


How can I run a shell script when some WiFi is connected? I have a really simple shell script, that just adds a route to my internal development machine. This is useful, as that machine has some LXC containers inside, so I can reach all my containers from my cell phone (to test websites from mobile browser, or Asterisk SIP accounts from CSipSimple)

#!/system/bin/sh
su -c "ip route add 10.0.3.0/24 via 192.168.0.200 dev wlan0"

To use this rule, I've created a new Local connection on ConnectBot, with the script name as login command. This works great.

However, I'm too lazy. I just want to know if there is some way to apply this script, as soon as I connect to my home WiFi automatically. Maybe something to execute a script on every network change, as I could check from same script if I'm connected to my home WiFi using dumpsys and some grep magic.

Matthew already pointed to tasker for this task (uh) – an app I already use for years. So let me add the steps to achieve this. Obviously, a pre-condition is the device is rooted – but the su command in the question tells me it is. So here we go:

Condition: State › Net › WiFi Connected
As parameter, include the SSID of your WiFi network, so it doesn't fire on alien networks :)
Task: Script › Run Shell
Here you add the name of the script to run (full path), preceded by an exclamation mark (to indicate it must be run as root)

This should do it. Not tested myself, as I have no routes to add :)


Every app in GAPPS works fine except Google Play Store and Google Play Services. How to fix them? I've done the factory reset, yet I see the  popups  "Unfortunately Google Play Services has stopped". I've  tried reinstalling the GAPPS but a weird situation came up.  I can sign in but the pop up Google play has stopped kept bugging. Plus every app under GAPPS works fine except for the Google Play Store which I cannot connect although I've signed in into my Google Account.

The two apps (Google Play Store and Google Play Services) has troubling me so much.  I've tried  reinstalling, clearing Cache, factory reset, and I can't find the button to uninstall updates for these two preferences. I've tried dozens of APKs, and various versions. I'm using the Lenovo Vibe Shot Z90-7 with Android  5.0.2, running on Vibe UI V2.5.

I installed a GMS Core(Google Play Services) version 7.5.71(1955121-448) apk.

I'm using Google play ver 3.1.11 (2044178-836)

This worked for me.


Is Cyanogen fully compatible with Play services and stock android apps? I am considering the upgrade of my Android Phone to Cyanogenmod as even with root, I am having several permissions problems, OTA updates removing root, etc.

The only reason I did not yet install it is because I don't know if it is compatible with the Play Store, and apps related. As I have alot of apps downloaded through the play store, and an AppData helium backup, I want to know if the backup will be compatible with the apps in Cyanogen.

My helium backup only has the backup of App Data, rather than the entire application source, as it is more space efficient

Samsung Galaxy S5 mini SM-G800F with stock Android 4.4.2 rooted

Luckily, Cyanogenmod is in fact compatible with play services. I am not sure about the stock apps that samsung has, as I didn't even bother trying to install them. The adb backup I made before going to CM restored properly. Google Apps are copyrighted, that's why they are not there initially. You can flash the Open GApps package as I found that to work for me best.


Messaging apps no longer work right after last update - Galaxy S8 Plus I updated 2 days ago.  Samsung Galaxy S8+    REV1.0

Now I no longer receive message notifications on my lock screen
The field to set the individual SMS/Message tone has disappeared as well
and ALL messages have the SAME sounds now.
I have no longer the option to  "Add a field" in the message apps either

Notifications are all turned on!

I use the Android message app and the Verizon message app.

It is Samsung's Oreo update.  They removed the feature.  Complain to them. The more that complain the more chance the will fix it.


Quick way to enter three dots (ellipsis)? The Samsung keyboard has a Quick Symbol key, where ".,?" are on the same key and accessed similar to the T9 method (don't know if this is standard for Android keyboards).

A good idea, but how can I quickly enter an ellipsis (three dots)? The best I could come up with is:

dot space del dot space del dot

Quite clumsy, but much faster than tapping dot and then twice wait until a next tap wont change the dot anymore. There surely must be a better way?

Update

On the Galaxy Tab there is no option to choose another keyboard layout; apparently on other Samsung devices there is (see GAThrawn's answer). Here you can see what options I can choose from:

I recommand you to install AnySoftKeyboard (available in Android Market), it a bloody good keybaord, by pressing 1 sec. on [.] key there is an additional key wit the three dots !
What I also find great in this keyboard is that you can install your country keyboard what the standard Androïd keyboard does not provide... Test it ... you will adopt it !


Does automated mapping with voice come pre-defaulted in Android without needing a data plan? Navigation is yes -- Does Android come with free navigation in non-US contries?

And it has voice -- Talking GPS software for Android?

But do you need a data plan?

GPS in most of the smartphones are aGPS.

  "Standalone" or "Autonomous" GPS operation uses radio signals from
  satellites alone. A-GPS additionally uses network resources to locate
  and utilize the satellites in poor signal conditions.

So in my phone HTC Desire, it automatically updates some GPS system file via Internet so GPS lookup can happen quickly. However, in normal GPS operation it won't require Internet so it doesn't require a data plan.


What is the filename for my contacts? What is the filename for my contacts on my optimus M running froyo?

It's contacts.db but it's not a normal file or directory, it's a SQLite3 database in the following location which you'll need root to access:

data/data/com.android.providers.contacts/databases/contacts.db


Reinstall TouchWiz Calendar I've been trying to reinstall the TouchWiz calendar on my Sidekick 4G with no luck.

I got the calendar apk here, and put it on my sd card then moved it to system/app using RootExplorer, and once I clicked install I got the normal install prompts then a message that said "Application not installed".

How can I fix this? Do I need to reinstall a stock ROM?

You don't install system apps, they're automatically detected.  After you move it to /system/app/ just remount system as read-only and reboot.  If your ROM's not deodexed that may not work but that's a whole other can of worms.


How do I get my contact list to display busines name also? How do I get the names in my contact list to be displayed WITH their organization? b/c I have business contacts who I may never remember by name but may need to contact someone from their place of business.

This is a paid solution, but if you download Better Contacts you can get the functionality you want.  And it's less than $3.


How to install Android ADB drivers on Windows? (Any Android Phone) How can I install the Android ADB drivers on a Windows 8.x PC/Laptop?
I followed tutorials on the internet but nothing worked for me.

  PS: The adb driver should be compatible with any Android smartphone.

There are many tutorials on the internet, and I will explain the best method here in my answer.

Download this program: http://www.mediafire.com/download/gy3g3gdc1vzcv6a/adb-setup-1.4.2.exe

A calendar with powerful alerts I just bought a Samsung Galaxy 2, coming from a Nokia 3600.

My old cell phone had a quite simple calendar app but when it was supposed to alert me it kept ringing and vibrating until I dismiss it.

I could quietly use an alert as a morning alarm if I knew, for example, I'll have to wake up at 6:00 on next 12/25.

In new one calendar just beeps once and I already missed a ton of appointments this way.

Moreover I started using alarms but there's no vibration available and it's limited in time setting.

I'm looking for an app to suit my needs, possibly syncing with Google Calendar, not too much bells and whistles but not mandatory.

Any advice?

Thank you

Edit:

As a note to who, gently is answering how to set calendar notification:

Please let me know also how to set it the way I need i.e. to make it ring until dismissed (or after, say, max 1 minute in case I'm far from the phone).

Otherwise changing from blip to din don won't help that much because I already tested it losing some appointments. :)

Calendar Snooze can repeat reminders until you acknowledge them, forever. It works with the default Calendar app, and will let it keep syncing with google.

You can customize how often the notification repeats, how many times (including "Keep Repeating"), and you can customize two sets of reminders, for example repeating every minute for 5 minutes, and then ever 5 minutes for an hour. It can also use notifications, the LED, text-to-speech, and alert popups.

It also (as the name suggests) allows a very powerful snooze mechanism, with completely customizable snoozes.


How to play/stream/cast sound and video separately to different devices What I have.

Portable Projector with DLNA & Miracast functionality.
5.1 Channel speaker with bluetooth.
Android devices version Marshmallow[6.0](Alternate devices with Lollipop[5.1] also available)

Current situation.

Movie(Video & Audio) streamed to projector from android device via DLNA/Miracast
Stereo Output from projector to the 5.1 Channel Speakers.

Problem.

5.1 Channel Speakers becomes just stereo speakers.
Speaker placements dependent on placement of projector.(I want to fix
them and not not    move them).

What I am looking for.

Stream ONLY the video playback to the projector from the android device
via DLNA/Miracast.
Stream ONLY the audio playback from android device to 5.1 channel speakers via bluetooth.

Can this be done? is there any app available for the same?

Possible with android 5. Using zenfone 2 videocast to WiDi and audio to JBL Charge 3.
It is not possible with android 6

The ConnectBot developers recommend Full Keyboard to issue keyboard shortcuts. But there are also other keyboards.


Reregister device with Play Store I was recently going through my list of devices on the web Play Store to remove an old device.  While looking at the list, I saw that I had two entries for my Nexus 4: "LG Google Nexus 4" and "Nexus 4".  As I installed CyanogenMod shortly after getting the phone, I wasn't surprised to see the second entry.  I decided to delete the one called "LG Google Nexus 4" as it was registered when I first got the phone.

Yesterday, I went to install an app to my phone using the web Play Store, but I no longer have any devices listed there.  I tried reselecting the account to use in the Play Store app, and also wiped data for the app using TitaniumBackup and relogging into the Play Store app.  Neither approach caused my device to be added back to the web Play Store device list.  How can I readd my Nexus 4 to the devices attached to my account?

From my understanding each device listing in the Play Store is referenced to a Unique ID. By removing the device you have removed this ID. You should be able to sign out of your Google account on your device, then sign back in, making sure all of the sync features are turned on, this should create a new UID for your device, putting an entry in devices once again.


Samsung Galaxy Mini GT-S5570 Gets disconnect during firmware upgrade via kies Whenever i try to upgrade the firmware of my galaxy mini gt-s5570 via samsung kies.....first KIES starts to download the firmware...but the phone doesn't show "downloading" on screen first...but every time (8-9 times that i've tried) when the download reaches around 69%-70%.....the upgrade process halts and says"PC cannot recognize the mobile phone" then the phone gets into download mode and shows "Downloading" on the screen! and i have to reboot my phone!

Disconnect your phone.
Reinstall the drivers.
Toggle USB Debug mode, reboot your phone and connect it.

If that doesn't work, try putting your phone into Download Mode manually.


Is it possible to use Recent Apps to close all open apps less the one I want to stay open? I have a scenario, or many, where I end up opening a ton of apps, and later on want to close them all at once, but keep 1 or 2 open. As an example, I use WhatsApp at home, and as we all know you cannot use the web portal without the app on your phone being on. So ideally I would have wanted to be able to use the Recent Apps feature of Android to close all apps, less say those selected as 'keep on.' And then if I really wanted to close them, I could then go into Recent Apps and manually close them.
Is there perhaps an app would allow me to script such a task, or any other solution?
I'm running Android 10 on a Galaxy A71 5G
Thanks in advance.

From the recent apps panel, select the app you want to lock, for example Chrome.

Press the 3 dots menu (above the Chrome panel) to show the lock option. Lock it.

and the small lock symbol shows up.

Now the app is locked and cannot be swiped away to dismiss the app. To unlock follow similar steps. You can clear unwanted apps by manually swiping away.
Alternatively, you can use apps such as Kill Apps, which allow you to customize the list of apps to be killed. Such apps are not usually recommended as Android manages memory space efficiently and such task killers can cause more harm by abruptly killing running apps.
See Recents Screen-Android Developers for more information.

How to skip “Welcome Page” in Chrome using adb I am trying to open a URL in Google Chrome using adb command line. Have set "--no-first-run" using following command -

adb shell 'echo "chrome --no-first-run" > /data/local/tmp/chrome-command-line'

Have taken the command line switch from the following website - http://peter.sh/experiments/chromium-command-line-switches/

Then I execute the following commands,

adb -s TA99300UFC shell am set-debug-app com.android.chrome
adb -s TA99300UFC shell am start -n com.android.chrome/com.google.android.apps.chrome.Main -d 'http://wikipedia.org'

Still the "Welcome Page" shows up.

How can I skip this and go directly to the website URL passed in command?

The problem was solved after the --persistent flag was added in the set-debug-app command.

So the command changed to adb -s TA99300UFC shell am set-debug-app --persistent com.android.chrome. After that chrome://version displayed chrome --display-fre under the Command line section.


How to transfer images via Android beam (NFC)? When I transfer an image from S3 to Nexus 4, Play store is opened. However, for contacts it works well and good. Do I need any app for transferring files over NFC?

The image transfer from S3 uses S Beam, which is a proprietary technology used by Samsung. It doesn't use NFC for the actual data transfer, but instead creates a WiFi Direct (ad-hoc) network between the devices and sends the image over WiFi. NFC is just used for "pairing" the devices. Since Nexus 4 is a vanilla Android, it doesn't have the necessary application for this, and I suspect this is why it opens the Play Store.

Instead, most NFC-capable Android devices support Android Beam, which uses Bluetooth instead of WiFi Direct to transmit the data. There is a suggested solution in another question that could work for you.


How to unlock password samsung mobile s4 galaxv I set a password in my phone model samsung S4. Now i don't need password option.I tried deactivate procedure.
i go to setting option then go to device and select lock screen then give a password then the final menu shows enable only visible Passward option only. what can i do that

You will see that if the device is encrypted, in that case you will not be able to move to a PIN or to disable the password.  You first need to decrypt the device and then try disabling the password. You can find the decryption option under settings - security. Hope this helps


Is it possible to reach hidden SMB/CIFS share from Android? I am using ES file explorer to browse my Windows shares. Now I made some SMB/CIFS shares with Linux, and it is able to make "hidden" shares, like this:

[priv]
comment = Private
path = /media/VIDEO/prov
available = yes
valid users = dims device
read only = no
browseable = no
public = yes
writable = yes

I can use this share from Windows if explicitly enter it's name. But looks like ES File explorer can't remember the link if it is not browseable.

How to overcome?

You can add a share directly in ES. From the LAN window, click New. In the Server text box, type the address and path of the share (e.g. server/priv), and fill in the rest of the form appropriately.


Sending text from Android to PC I'm looking for the inverse of this.
I want to quickly transfer a piece of text from android to my computer. One way to do is chat with myself using gtalk or fb. But I'm looking for some better way preferably without using Internet and using wifi only. It would be nice if I have a "People nearby app" that can talk with empathy client.

There's an app called Remote Web Desktop by SmartDog Studio. It enables access to your phone through your desktop's browser, over the local network (i.e. no connection to the Internet is necessary (I use it with both phone and desktop on the same WiFi AP); phone acts as HTTP(S) server on non-standard port (configurable)).

The simplest method is "shared clipboard": select the text on your phone, copy to clipboard, and it's immediately accessible from the desktop computer.

The app has a free (ad-supported) and paid (~$4 USD) version; the free version allows connection over HTTP, paid also offers HTTPS.

Full disclosure: I'm a (happy) user of this app, no other connection.


How to fix "mount: 'remount'->'/system': No such file or directory"? angler:/ # mount -o rw, remount /system
mount: 'remount'->'/system': No such file or directory
1|angler:/ #

When I try in Kali Linux in my phone:

root@kali:~# mount -o rw, remount /system
mount: /system: special device remount does not exist.
root@kali:~#

Am I missing something?

You  have added a space between the two options you passed: rw and remount. You need to remove space after the comma , and then repeat the command like this:

mount -o rw,remount /system

This should work. Tested on OnePlus 6.


Forcing landscape orientation when phone is upside down When lying on the bed with my head on the pillow, I basically can't use my (mi4) phone: if I hold it upright, it goes to regular portrait mode and it's not aligned with my eyes (my head is on the pillow). If held upside down, regular portrait too. If held horizontally (top & bottom of the phone facing the walls) it switches to landscape, still not aligned with my eyes. In fact, it is entirely incompatible with this body/head position.

How is that possible ? Using a phone in this position is incredibly common yet you just can't ! My Lumia 520 (Windows) understood that the phone upside down means the user is lying on his/her bed, head on pillow, thus switched to landscape, so I could watch YT videos and browse websites in landscape.

Anyway, is there an app or anything to, for example, force the phone to stay in landscape when phone is upside-down ?

Depending on what version of android/ROM you ate running there should be an option to lock the orientation. It could be in the quick settings in the notification drawer, or settings > display > orientation.


Lollipop Contact Count I have a Nexus 6 with Lollipop 5.0. I am wondering how many contacts I have on my phone. Of course I could go through and count each one but is there a way to put the contact count at the bottom sort of like the iPhone contact count. How

How can I enable this?

Thanks.

In the Contacts app, press the Menu button and select Memory status.
Then you get a screen displaying you the total number of contacts used for every single account/storage.
This only works for custom ROMs, though (don't know why).


How to delete Skype history? How to delete Skype history?

I saw two methods declared: (1) delete Skype application data and/or (2) reinstall Skype.

But both methods are compromised by an idea and saying, that Skype history is (maybe partially) stored on Skype server.

If so, then History will resurrect after both actions.

So, my question is: how to really delete history?

Also I need some explanations about the cases where history was resurrecting. For example, this can be because parallel client was holding history...

Go to Settings - Apps, find Skype in list of installed apps and click on clear data button and clear cache.

  Also I need some explanations about the cases where history was resurrecting. For example, this can be because parallel client was holding history...

Skype archives your chats for you and stores them locally on your computer (or device), if you have enabled this option. Chat histories are not stored anywhere on the Skype network. source


Can we use Moto G2 with google Cardboard Can I use Moto G2 with Google Cardboard. I just want to experience Virtual reality in a cheapest way possible. I've a Moto G2, So I was wondering If I can use Moto G2 with Google Cardbaord. If anybody has used it then please suggest me, What kind of stuff I would be able to see and what I won't be able to.

Yes, your phone should fit. Only you will not be able to use ring button because moto g2 doesn't have magnetic sensor.


I cannot stop my Google contact addresses from displaying in Maps On my phone (Note 8, Android 7.1.1), when I go into Maps and Your Places, I see hundreds (around 400) of addresses from my contact list under the Labeled tab.  Everything I've read says that if you don't want these address to display, you should go into Settings | Personal Content | Google Contacts and move the slider to the off position.  I did that (Google Contacts is now grayed out), but all of the contacts are still showing.  Hiding them one at a time would be a nightmare.

I've tried forcing the Maps app to stop hoping that would force the app to refresh the address list, but that didn't work either.  I have even tried clearing the cache and saved data for the Maps app but these Contact addresses are still showing up.  Any suggestions?

The setting you are talking about will only remove contacts from showing up in the actual map.

To remove contacts from showing in my places tab, do the following:

settings  → Google  → [general]  →
Personal info & privacy  → Activity controls  → Web & App Activity  → Turn "Web & App Activity" off


Change main Google account login address When I activated my first Android phone, the Galaxy Note, last week it forced me to create a Gmail account for it.

Seeing no other way out, I did as I was told.

However, seeing yet another google mail address pop up was quite annoying, so I decided to try to get rid of it.

I managed to remove Gmail from my account permanently, and go back to my normal e-mail address to login to Google, but my Android device isn't following. It still has the gmail address set as login.

Is there a way to just change the login address? The account behind it is the same.

If you aren't rooted, you've to do factory data reset to change your primary Gmail acccount. (Settings > Privacy > Factory data reset.)

If you are rooted then you can use a file manager program to rename  /data/system/accounts.db file and restart the phone.

You can find the detail steps with illustration here.


Android fastboot restoration points Does Android have restore points that can be accessed via fastboot?
In Windows7 (support ended February 2020) restore points are created so the OS can revert back to last known state should anything go wrong. This revision includes settings, software, browser history, etc. This handy feature has helped me several times. Does Android have such a utility/feature where by any means (fastboot or adb) it can be rolled back to last known state? Kindly read more to understand the full situation.
My phone is stuck in fastboot. I have been doing research on how to get it out of this. The phone runs Android Go. Usually the OS updates and completes without any issues, but this time during an update the battery died and upon power up it got stuck in Fastboot mode. I understand both Fastboot and ADB have commands of their own that can be used to interact with Android OS via USB connection. I have a question that my research has NOT answered. Before I run any commands in this mode (fastboot) I want to know, is there a way to restore the device to its last stable state (ie before the failed OS update)?

you can try
fastboot --set-active=a

or
fastboot --set-active=b

ane one of them should work if your other slot is not corrupted


What is the Android Answer to Air Video Server? I just switched to a Droid X and I love it. One of the things that keeps me from not needing my iPod touch is Air Video. Is there a similar system that can run on my network?

DLNA is basically the same thing.  There are several apps that allow you to use DLNA like Twonky.


Any changes to files in root directory (/) are gone after reboot On linux, "/etc/fstab" contains the directives how a partition should be mounted (fs type, flags etc.). On Android how it is determined?

On my Nexus 7, I see a file called "fstab.flo" in "/" which contains similar information as fstab does. Just to determine that this file is used by Android during booting, I commented the line corresponding to the mounting of /data partition (With root permission). And booted the device. However, that does not bring any change. Device booted fine, and my changes to that file are no longer there.

Sure not. All changes made there are gone with the next boot: you are just modifying a file on a "temporary file-system" here, which is created on boot, and "gone" on shutdown.

For persistent changes, you would need to change the boot image. As you compare with Linux on a PC, think of a initrd.img (initrd aka "initial RAM disk, or initramfs). The root file system is loaded from this during the boot process (step 3, kernel).

Please excuse me for not going into more details: but how that's done is beyond the scope of this site (which targets end-users, not developers); and beside that I have no practical experience in this specific field.


I want to password lock my "Applications" settings, but no other settings I have an AppLock program that locks certain apps with a PIN.  In order for the app to have any effectiveness, I include Settings as an App to lock.  Otherwise, I could go to Settings -> Applications and simply kill the task.  The disadvantage to this is that if I lock Settings I cannot do simple tasks like Calling Settings and Display.  I would like the ability to fine tune exactly what settings I lock.  Is this possible?

I'm running Froyo on a Samsung Captivate.

I believe the basic answer is no.  Obviously it can't be done with AppLock since all the settings are accessed through the same app, but further than that you would have to somehow determine what the Settings app was doing and prevent it.  This would be very difficult, and impossible without root.

I think the Settings app must be open-source, however, given that manufacturers can customize it.  You could possibly modify it to lock out the application settings unless you enter a password, or something.  That's beyond the scope of this site, however.

Another alternative is widgets that alter the settings directly.  I'm sure you can get a widget that would allow you to edit the brightness and that sort of thing without going through the Settings app.  I'm not exactly sure how widgets like this work, however; it's possible they might call into the Settings app, which would prevent this.

In that last case, it might also be possible to set up something like AppLocker that allows Settings to run if it is triggered by a "privileged" application.  You could make the brightness widget privileged, so that the Settings app can make the brightness change when requested to, but everything else would still be protected.  I assume AppLocker can't do this, but it might not be hard to develop (again, out of the scope of this site).

I know this is kind of vague, but hopefully it provides some sort of help.


Stopping an ongoing download without exiting Chrome I have a file that has been stuck at "2 seconds remaining" for about a day. I feel it's never going to finish, so I want to know how to cancel it without quitting or stopping Chrome.

None of these have worked:

turning off data and WiFi.
force "Downloads" or "Download Manager" to stop.
clearing the data of "Downloads" or "Download Manager".
the suggestion to force "Download Manager" to stop and then press "Clear Data" does not work because "Clear Data" becomes grayed out after hitting "Force stop".
going into notification bar and pressing for some kind of cancel option.

The Download manager is just a viewing app for seeing all downloads you have done clearing it or forcing it to stop will do nothing(it will just clear the app's data and cache)
You might want to try clearing cache of chrome app since that's the app you used to download the file by going into Settings -> Apps/Installed apps ->Locate Chrome app -> Clear cache
If this still doesn't solve your problem you might want to clear data of the app as well (same procedure as above just click clear data) WARNING: Clearing data will clear all bookmarks,sometimes the files that were downloaded using chrome and sign you out of chrome(which you sign in after clearing is complete) So better move all the downloaded file to other location before proceeding
(Not a risky process i get the same problem randomly and do the same thing most of the time clearing cache does the job)


How can I factory reset my Android Mini 7100 Phone? I'm unable to go to recovery mode to factory reset (wipe my cache/data) my Android Mini 7100 Phone (Android GingerBread 2.3.x) because I forgot my phone lock combination.

I tried resetting it using:

Vol Down + Power,
Vol Up + Power,
Vol Up + Vol Down + Power,
Vol Up + Vol Down + Home + Power,

and the phone starts normally

When I press Home + Power, it goes to 'Test' mode.

I checked out this YouTube video but it did not work for me.

How do I go to recovery mode?

I think the easiest (and non-sketchiest) solution for this will be to help your sister recover her Gmail password. Once you have that, you can use the Android Device Manager to reset the phone password, or erase the phone memory from the computer.

This is the only solution I will post here because resetting an android without access to a gmail account is often done with less-than-ideal intentions.


Do the apps purchased via SlideME.org give you notifications about available updates? SlideME is a website where you can purchase apps (useful for countries where Play Store does not support purchase yet).

Will I get a notification if their apps are updated?

SlideME Application Manager (SAM) will notify you if there's an update to the apps purchased from SlideME.

  SAM supports SlideME's Storage Locker. This allows you to re-download or upgrade Android applications you have previously purchased in case you lost or reset device.


Trading clipboard contents between phone and computer Is there a way to send information on my phone (for example, an SMS that I started to type, that got way too long, and that I decided I want on my computer to send as an email instead) through the clipboard? There are ways like sending myself emails, but they're not exactly great, on top of me finding absolutely no decent way of using email on my phone.

In an ideal world, on my phone, I would like to have a "right-click" (hold-the-tap) option, "Send to PC", and if Wi-Fi is enabled, I would just go to my PC, perhaps authorise the received clipboard (not sure that would be necessary or convenient), and then just Ctrl-V somewhere, and voilà, it pastes what came from my phone in my browser/Skype conversation/Word document/etc.

Also, I would very much like a similar option to go the other way. To send things typed from my computer to my Android device. In an ideal world, through a right-click option called "Send to Phone", or even a keyboard shortcut like ctrl-alt-shift-C. But this part, I'm not sure if it wouldn't belong on SuperUser more.

My PC uses Windows 8. My phone runs 2.3.6 Gingerbread.

My phone is a Samsung Galaxy Q (SGH-T589W).

For your information, this is almost the same phone as the Samsung Gravity Smart. Or literally the same phone. These dual names confuse me.

Samsung Kies does NOT work for me, so no use mentioning it (unless you can make it work unlike the Samsung support people I contacted, but this would belong in another question).

If all you care about is the clipboard sharing, you might want to take a look at ClipSync. This app allows you to share your clipboard between multiple Android devices and your Windows PC: Copy on one device, and it appears in the clipboard of all others. At least that's what the app description says (all Windows I have are just for fresh air and light coming in, or to look out of them (not Out-look), so I cannot verify). A 4.5 star rating suggests it works -- and it's only 150kB "big".

If you want a bigger benefit, take Compro01's advice and have a look at Airdroid. It's a great app, and lets you maintain your Android device from any web browser in the same WiFi network really nice (edit your contacts, write SMS, browse pics...). An beside that, allows for clipboard sharing.


Drawer button to toggle enable/disable lock screen I am looking for a way to enable the addition of a button in the android drawer which acts as a toggle for enabling/disabling the lock screen. I want to use it to toggle lock screen on when I have to put the phone in my pocket, and lock screen on when I leave the phone on my desk.

Thanks.

Finally! Someone developed an app which enables you to lock the screen by tapping a notification drawer entry or in several other ways. The app can be found on the play store. Here it is:

Unknown error code during application install "-24" I just updated my Moto X to latest and greatest Android 4.4 KitKat (I even did full factory reset just to be sure) and now I'm trying to install WhatsApp Messenger but unable to do so, I'm getting following error:

  Unknown error code during application install "-24"

Please advise.

According to a thread on AndroidCentral, this is a problem with either...

the app itself having trouble to update an already installed version (unlikely after a factory-reset) → uninstall first, then try a fresh install
certificates not being handled properly → install from a different .apk (e.g. one from your backups, if you've made any, or from an alternative source)
certificates (variant 2) → Go to Settings→Apps, select the "All" tab, scroll to Google services framework, tap the entry, "clear cache", "uninstall updates". Repeat the same for Google Play Store, then reboot, then try again

I didn't verify this (don't have the issue, so I didn't even have the chance to), but it sounds reasonable.

Additional sources on this error:

Unknown error code during application install: "- 24 " (XDA Developers)
App description of the PocketTool App:

  The -24 error is a killer. People think it is because of PocketTool when it is actually the device. You may want to include in the description that if they get the -24 error to reboot the device, then try reinstalling mcpe. If that doesn't work, uninstall all apps that could be used to modify the game, reboot, and try again. If even that doesn't work, the only other option I am aware of is to back up important things such as Kindle books, music, movies, and saved app data on something (I used my laptop) and do a factory reset. If they are on Jelly Bean, then they will get a -24 error if they try to reinstall mcpe after a failed mod install.
  Users had the same trouble with Spotify. A second factory-reset solved it.
  A thread on Android-Hilfe.DE (German) again supports the first variant of my answer (remains of a previous install). Maybe your factory-reset did not complete cleanly.
  A Google search on "google-play error-24" reveals even more sources.


How to end call via adb in android 2.2.1? Im creating small call center like system based on pyadb.

I was developing for my phone which has custom SlimKat ROM - kitkat based.
To call i do :adb shell am start -a android.intent.action.CALL -d tel:xxxxxxxxx

To end the call i do input keyevent KEYCODE_ENDCALL
and it works like a charm on my phone.

But now my boss want's to use old htc wildfire (buzz) with android 2.2.1
On this phone adb input keyevent KEYCODE_ENDCALL gives me '[1] Killed ...`- error.
I tried to use keycode number instead of KEYCODE_ENDCALL, like this:

adb shell input keyevent 6-

this is not giving error but does not have any effect on the phone.

Same for KEYCODE_MUTE.
Curiously KEYCODE_CALL(7) is working as expected.

How can i make it work? Can i change adb commands in anyway? Or maybe installing CyanogenMod(7- I think is the newest for this phone) will help?
Or is this lost fight and i need a newer phone for this?

Found that and it works for making and ending calls. Still looking for a way to mute Microphone.


How to download all photos to one folder like in iPhone iOS saved all photos in one folder but android saves it in different folders which is difficult to organize. Does anyone know how to make Android save all photos in one folder.?

i am using samsung galaxy s3 with custom rom 4.2 & using quickpic app for photos

thx

Photo saving location is up to the individual apps.  Stock Android camera app, for example, always writes to SD Card's DCIM\Camera folder.  Other photo taking apps may have a different default location, but you should be able to change that in those apps' settings.

Various photo managing apps will try to scan your entire SD Card for images, and may pull in folders that belong to various other apps, not necessarily Camera/Camcorder.  Such apps usually have setting to specify which folders to include or exclude during such scans.


Restore Droid Explorer Backup How do I use Droid Explorer to restore a back up either the enhanced or normal ab?

To restore you open Windows Explorer and navigate to the backup directory.

c:\users\[username]\Android Backups\[device_id]\

There you will see the backups for the device. You can then double click on the backup file and restore it to the device.

If it is an Enhanced Backup, it will only be allowed to restore to the device that it was taken from.

You can also convert Android Backups to Enhanced backups, and vice-versa by right clicking the backup and choose 'convert to xxxx'.

You can also choose to unpack a backup. This will basically extract the contents of the backup so you can browse it on your computer.

When you start the restore, it will run the adb restore command on your device, using the backup selected.


Android x86 official I'm wondering if there's a distinct, official version of x86 android that's different from the ones made through the Android-x86 Open Source Project (http://www.android-x86.org/). I'm asking since that project was started some time ago and predates versions of android that officially support x86. Also, I'm now seeing phones that use intel atoms running android like the Asus ZenFone 2, so do those phones use the same iso images provided by android-x86.org? If not, what's different about the x86 android os those phones are running compared to what you get from android-x86.org?

First of all, what do you mean by official? You mean released by Google?

And no,  the firmware on Asus's x86 Android devices are certainly not the same builds released by Android x86.

All Android releases are based in one way or the other on the code released by the Android Open Source Project, a Google initiative.

Anyone could take that source code, customize it, and make their own Android release.

Android x86 also uses this source code, but they have put in heavy work compiling it for x86 and constructing a kernel that's compatible with normal PCs. Android x86 is explicitly unofficial, and is not affiliated with Google.

Remix OS is a derivative of Android x86. While it is built by former Google employees, it is also unofficial and not backed (nor opposed) by Google.

Asus distributes their own Android builds for their x86 devices, but it's not Android x86 as in the PC project I referred to above. Asus Intel phones are (unfortunately) not normal PCs where you can just install any OS you want. (Although that would be super cool if they were.) They are just like any other Android phone (except they have x86 processors), in the sense that they require a ROM that is specifically tailored to their hardware. (Unfortunately, Android devices don't follow a convention the way PCs do.) Asus develops such tailored ROMs, in the form of their stock firmware.

Is this firmware an official x86 version of Android? It depends what you mean by official. It is officially developed by a large corportation, Asus. It ships with official Google software, apparently approved by Google. I don't know if you could call that official. Depends on your viewpoint. However, these ROMs are strictly for the device they were built for. It's not like PCs where you can just swap OS installers around and use any OS on almost any device. (Again, I really wish it was, but what I personally wish for is not really relevant here, so forgive my blabbering.)

I'm not aware of any Google product (like a Nexus) with Android and an x86 processor.

Interestingly, Google is bringing official Android compatability to Chrome OS, a somewhat popular PC operating system that runs on both ARM and x86 and is also (mostly) released under the open source Chromium OS project. Both Android and Chrome OS run on the Linux kernel. So what differentiates them? The userland and other components (which is a huge difference.) It looks like, however, that Google are porting all or most of the Android userland to Chrome OS. So would Chrome OS then qualify as an "Android release"? Well, it depends on how you define an Android release. It runs on a similar Linux kernel and has most of the same userland integrated. If you're willing to stretch yourself, I guess you could call that an "official Google Android release for x86." Of course, it also has the Chrome OS userland. But Maru OS similarly has the whole GNU userland, and Maru OS is still and Android release.

Confusing? Yeah, I guess it can be. Thankfully there are some pretty smart engineers working on all of this. After all, Android is one of the most popular and user friendly operating systems on the planet.


android thinks accounts.db is corrupted and deletes it After a reboot, i lost all my accounts. i looked into the logcat and got:

04-02 11:54:01.535  5305  8068 E SQLiteLog: (11) statement aborts at 24: [SELECT key, value FROM extras WHERE accounts_id=(select _id FROM accounts WHERE name=? AND type=?)] database disk image is malformed
04-02 11:54:01.537  5305  8068 E DefaultDatabaseErrorHandler: Corruption reported by sqlite on database: /data/system/users/0/accounts.db
04-02 11:54:01.538  5305  8068 E DefaultDatabaseErrorHandler: deleting the database file: /data/system/users/0/accounts.db

I restored the file completely from a TitaniumBackup XML-file (so the database is created cleanly again, no backup of a possible corrupt db file).
After a reboot, android deletes it again and recreates it, accessing it just after restoring (i.e. using a program, which looks up an account) gives the message

04-02 11:45:22.855 12225 12225 W System.err: Caused by: java.lang.IllegalStateException: The database '/data/system/users/0/accounts.db' is not open.

just after restore, i can open my accounts.db with sqlite3 and SELECT * FROM ACCOUNTS returns a correct list and SELECT key, value FROM extras works as expected, too.

The file permissions are

-rw-rw---- 1 system system  72K 2017-04-02 11:55 accounts.db
-rw------- 1 system system  17K 2017-04-02 11:55 accounts.db-journal

My ROM is a CyanogenMod 13.

I got it fixed, even when i do not understand what happend

I checked the created sqlite file with PRAGMA integrity_check;, and after reindex and vacuum i actually got a message its corrupted (not before).

I tried to recreate it like in this blogpost and set the file permissions, which caused a bootloop.

Then i rebootet to recovery and replaced the accounts.db with a empty one from a second account on the phone and then read the dump_all.sql created before into the database.

Now it works, even when i do not know what's the difference between reading the data into a fresh database (which caused a bootloop) and reading it into a android created empty database.
It may be related to missing selinux contexts or something similiar.

So the working steps for anyone with a similiar problem:

dump the data from the possibly broken db (even when freshly created by TitaniumBackup)
copy an empty db
import the data into the db
reboot


Is it possible to connect two headphones to the phone without any splitter? I need to connect two headsets to my smartphone. I know that I can't do it via Bluetooth, but maybe its possible to connect one via Bluetooth and another via audio jack?

You can do it even via Bluetooth. Just search for proprietary Bluetooth technology ShareMe. For example:
http://www.cnet.com/news/get-two-pair-of-shareme-bluetooth-headphones-for-56-98/
http://www.amazon.com/ShareMe-Bluetooth-Headphones-Wireless-Technology/dp/B0152GBS66

ShareMe technology lets you to stream music wirelessly to another ShareMe equipped headphones.


View app's full package name? I am using Android 4.0.3 and I can no longer find package name for some app. If I recall, I used to go to Applications and has been able to see it there.

So, how can I see full package name of some app? Like, the app's name is "Test" and I need to see its package com.test.mytest.

If you're comfortable using the command line, a solution I like is Android's pm command. It can easily be called using adb like so:

$ adb shell "pm list packages -f test"
package:/system/app/AutomationTest_JBUP.apk=com.sec.android.app.DataCreate
package:/system/app/BluetoothTest.apk=com.sec.android.app.bluetoothtest

Replace test with whatever package you're looking for.

pm has a variety of options that may be useful depending what you want to do:

usage: pm list packages [-f] [-d] [-e] [-s] [-3] [-i] [-u] [FILTER]
pm list packages: prints all packages, optionally only
  those whose package name contains the text in FILTER.  Options:
    -f: see their associated file.
    -d: filter to only show disbled packages.
    -e: filter to only show enabled packages.
    -s: filter to only show system packages.
    -3: filter to only show third party packages.
    -i: see the installer for the packages.
    -u: also include uninstalled packages.


Getting Segmentation Fault on recovery It's an Android 4.0.3.
I'm trying to fix my tablet, because it doesn't start anymore.

running fastboot devices returns nothing.

Then, I'm trying to do that through adb.
adb devices returns

List of devices attached
20080411        device

So I guess adb should be working, but when I try this I get a segmentation fault:

adb shell
recovery

I already tried many varations of button pressing on powerup, but nothing seems to work.

Any idea on how to fix it?

fastboot is when you enter fastboot mode, by powering up with volume up key pressed. Then fastboot devices would work.

Why are you invoking the recovery on its own via adb shell?

The recovery binary is reliant on the startup scripts used within the recovery partition unless the partition is messed up.

Recovery only works by powering up with volume down key pressed at the same time.

The vital details are missing from the question. :)

What device are you trying to fix up in respect to getting into recovery?
How did it happen? What did you do?


Create customized zip including system.img, boot.img etc for Android customized ROM I downloaded AOSP source code and built it as instructed in its official site.
Now I have 4 img files as system, boot, recovery, userdata. I want to create a zip file which should include these files and can be installed via a recovery manager like 'Clockwork mode recovery'.

For an example we can install CyanogenMod customized rom zip by using clockwork recovery while in boot up process of device. Like wise I need to create a zip including my own imgs.
How should the folder structure of the zipped file system should be created, what script files should be included and how that scripts should be written etc.

Used this link (http://lazydroid.com/2011/03/howto-repack-and-sign-rom-image-update-zip-files/) but how to create /META-INF/com/google/android/update-script is not well explained there.

Recently I found a source that can help you to create update-script. Here it is: http://marakana.com/s/updating_android_os_via_ota,1065/index.html


"/sdcard/Sounds" folder appears empty in Windows 7 for Samsung Galaxy S3 For some reason, the folder that once allowed me to access all my recordings using the default Sound Recorder app appears empty in windows even though the files are still there according to ES File Explorer. My phone is not rooted.
(Similarly, some files in my Downloads folder are not visible from Windows.)
I've also begun having an issue where deleting folders in the "Music" directory gives an error "cannot delete _____ the storage is write-protected.", but I don't know if this is related. I really need these recordings without having to "share" every single one of them individually in ES File Explorer.
What is going on?

Being aware it is not a full-fledged solution but rather a workaround (it's still unclear what's causing the underlying issue), this answer sums up what we figured being a work-around at least:
As the files/directories don't show up the usual way via "sharing the SDCard", they can still be accessed by other means. One example is using ADB: using adb pull files can be transferred from the device to the computer, and with adb push in the other direction. Examples:

adb pull /sdcard/Sounds/ E:\audio\phone would take the entire folder /sdcard/Sounds and save it as E:\audio\phone on the computer
adb push E:\audio\phone /sdcard/Sounds/ for the opposite

The culprit: types of "source" and "target" must match. If "source" is a file, "target" must be a file as well: adb pull /sdcard/Sounds/some.mp3 E:\audio\phone would fail as the source is a file and the target a directory.
Other draw-backs can be worked around as well: if you prefer a graphical solution over tinkering with the command line, there are several good GUIs available, e.g.

QtADB
Droid Explorer (by our member Ryan Conrad)

And several more. As a side-effect of installing ADB, you've got a powerful tool ready which will certainly help you with many other things!
For getting ADB to work without installing the full SDK, please refer to Is there a minimal installation of ADB? More ADB related information can be found via our adb tag and its tag-wiki.
Alternatives include several "WiFi file managers", which are too many to be listed here. So if you rather want a "simple app installed" on your Android device, and then do everything with your browser, you might wish to take a look at the following lists:

Manage your Android Device from your Computer
FTP Server
Various File Servers


Changing Assistants with Google shortcut I know Owlswipe posted a similar question, but it wasn't quite what I was looking for. On my Samsung Galaxy S6, if I hold down the home key, it launches the Google Assistant. Is there a way I could change this so it launches Cortana instead? I was able to do this with a different phone when the assistant was Google now, but I can't find the option for this anymore. Last time, when I downloaded Cortana, and did the shortcut, it would prompt me to change Cortana as the default app for that action, but it didn't do that this time.

Andrew T's answer in the coments ia the answer. To change default apps, including the default assistant, go here: http://www.pocketmeta.com/change-default-apps-android-marshmallow-33779/


Getting rid of certain configuration messages Just got my first smartphone and I've been trying to get rid of configuration messages that my provider sent me. The problem is that i got sent too many of those, I've installed the ones I needed but I don't know how to get rid of the extra ones. If anyone has any advice how to do that, it would be appreciated. I've been thinking of restoring the phone to factory settings?

It's a samsung S4.

Thanks

Those configuration messages are sent as SMS, so you'll find them in your messaging application – where you simply can delete them:

Usually, long-pressing on a single message opens a popup-menu, which a.o. holds an item to "delete" the message. Hit that. With some message apps, this reveals check-boxes next to each message in the "thread", which you can tick before hitting the final "delete" button – and gone they are.

You might also be able to long-press the entire "thread" (if those messages are grouped into one) and have a "delete thread" item in the popup, which even would speed up the process (no ticking each message separately).


How do I view hidden folders with Solid Explorer? It's easy to create hidden folders/files by starting their name with a dot (e.g, ".nomedia"). Once created, how do I view/delete them using Solid Explorer?

Tap the three dots in the top right of the app
Choose 'Folder options'

Ensure 'Show hidden files' is ticked (option is unchecked in screenshot below)


"Unable to connect to the proxy server" after updrade to Android 4.3 My Samsung S4 has been experiencing the problem of "Unable to connect to the proxy server" after upgrade to Android 4.3, all the apps need network (HTTP) are not working, no matter
using 4G or Wifi connection. For apps which does not require HTTP connection such as Whatsapp or Google Search which is ok.

I have double checked the Proxy setting in my Wifi Setting, which is set to none, so are there anything I have missed or misconfigured?

Tap and hold the WiFi button, then select "Forget Network". Afterwards, search for the network again in the list, enter the password and you are good to go.


Configure Tasker as alarm for date and time Could someone be so kind as to show me how to set Tasker to play a melody selected by myself when 5 June 2016 @ 10 PM is reached. I would like to be able to set the sound file to play, perhaps in a loop. Thanks.

Before you start having us write a new Tasker profile every day (kidding :), let me give you some help to help yourself: My site holds some Tasker Graphs showing you what conditions and tasks are to be found where. So based on that, here's what you'd have to do.

The profile

Condition:

Time › set the time you want this profile to be active
Date › pick your date here

Task: Media › MusicPlay › select your music file

Pretty basic stuff. Below the graphs you can also find a list with Tasker Tutorials – recommended reading :)

Notes

Tasker always connects multiple conditions per AND – so it's always "condition-1 AND condition-2".
When creating a new profile, after having chosen your first condition Tasker will immediately continue asking you for the task(s). So complete those first, save the new profile, then long-tap (tap-and-hold) the first condition. This will open a context menu from which you can chose to e.g. add another condition or add an exit-task
You cannot have multiple conditions of the same type for the same profile. So if you want e.g. the same task executed at two different times, you have to create two profiles; but when creating the second profile, you can simply pick the task created for the first (or any other) profile from a drop-down.


What way of controlling volume is more battery efficient? I have a headset with it's own volume control, and I can also control the volume of the music through the android's volume control keys.
But which way of controlling is more battery efficient?

Have my android device on full volume and control it with my headset's control.
Have my headset on full volume and control it with my android device.
None of the answers above. (if so, then which?)

EDIT: I'm not talking about an electronic controlled headset, I'm talking about a headset controlled by a dial resistance.

Conclusion first: It doesn't really matter as this operation needs almost no power anyway for both ways.

Changing the volume alone has only a minimal affect on the battery given the screen stays off.

Reason: If you listen to music there's already some processing going on and increasing/decreasing volume levels has a very low processing demand (almost none). It's more of a side-note event for Android.

The volume buttons on the side of your device trigger some event and so do the buttons attached to the string of your headset. I'd say it's equal or at least very close to equal.

You can have a look over at George Smart's HTC headphone analysis and see that the L channel is not shorted against the common ground. Instead some coded resistor values is used to pull the common control line (also used for the microphone) which probably has a high impedance.


How to save something to Instapaper with TweetCaster I have TweetCaster Pro (thank you Amazon Daily App...) and it has a place for me to enter my Instapaper account in the Settings, but for the life of me, I can't seem to figure out how to send something from TweetCaster to Instapaper.

Anyone know how?

This one took me a while. Go into "Personalize TweetCaster" in settings and change "URL action" to "ask".


Can't boot into system or recovery I had the Pixel Experience ROM on Redmi Note 7 Pro which got an OTA update and after the update was installed it got stuck on the boot logo of the phone, the usual keys for recovery mode don't work. Reinstalling the recovery through fastboot flash and fastboot boot gives the same result. Sometimes it shows warning: Your phone is destroyed press power button to turn off.

How can I recover from this? This is the ROM that was installed through OTA.

You can try to boot directly into recovery instead of flashing image: fastboot boot recovery.img

If it doesn't work, go for flashing factory firmware in bootloader or Emergency Download mode. Here are the detailed instructions for Xiaomi devices.


Operate LG G2 phone from Desktop My LG G2's screen just got a chip in it, and consequently only the top 1/4 of the screen will register touch.

The phone is not rooted, but I have developer options and USB debugging activated. Is there any way I can mirror the phone on a PC or Mac? (I prefer Mac, but have access to Windows 8 as well.) I'm talking about full control with keyboard and mouse.

I just want to know if I can hobble through until the new Nexus comes out and I can finally be rid of this old phone.

Try Vysor first. As long as USB debugging is on you shouldn't even need to do anything on the phone to get it running. Mouse simulates touch while keyboard input is passed through. If you don't type in English then input method support might be a bit clumsy.


AVD Pixel_XL_API_30, emulator process gets killed every time in Android I just downloaded Android Studio's latest version being: 4.1.3 (18 March 2021) with the repository being: android.googlesource.com/platform/tools/adt/idea. The problem is that my AVD Manager is unable to load any of the Virtual Devices, however, light it might be. Currently, I am using Pixel_XL_API_30.

It shows "The emulator process for AVD Pixel_XL_API_30 was killed."

Can anyone tell me if this new version problem or is a bug?

The most frequent reasons for this is

Windows: Not enough disk-space on drive C: (where Android stores its emulators)

Enabled Windows hypervisor!

Hit Windows-Key and enter 'features', select 'enable/disable Windows Features'
Disable 'Windows Hypervisor Platform' (this disables Windows Subsystem for Linux as well)

This worked for me, you currently can't have both unfortunately even in Windows Pro.
Edit: There seems to be a solution with Hyper-V


How to get 2 android apps working simultaneously? I'm using a Using Samsung Galaxy S7, Android 6.0.1. and I'm having trouble using apps in parallel. Here's what triggered this post:

I got myself and iRig2 to practice playing guitar silently, downloaded AmpliTube, plugged in the guitar and it worked, I could hear my guitar back and apply effects, change amps, etc..

On to the next step, to play over backing tracks. IK Multimedia advises to use apps like Riff Maestro with AmpliTube running in the background. And this is precisely my problem, I can't get AmpliTube to keep running on the background!

Here's what I tried so far:

Test 1:

open AmpliTube (app), plug in the guitar and check it's working. If it is:
press home button
open Riff Maestro (app)
as soon as I click the home button, AmpliTube stops sending guitar sound out

Test 2:

open AmpliTube (app), plug in the guitar and check it's working. If it is:
press the home button (AmpliTube stops sending sound out, as per Test 1)
open Riff Maestro (app)
press the "Recent applications" button
swap to AmpliTube, it starts sending guitar sound again
press the "Recent applications" button again to swap for Riff Maestro
AmpliTube stops sending sound again

I tried splitting the screen but none of the apps supports split screen.

The question is, how can I get 2 apps (in this case AmpliTube and Riff Maestro) working simultaneously so I can hear my guitar on AmpliTube AND play a back track on Riff Maestro?

Many thanks in advance!

That's a really good question! Thank you for asking it though.
On Android Programming, There is something we call, Activities LifeCycle
Imagine, when you pressed the home Button, The current Activity is going to onPause() method which it stops the Activity and it's not longer active because this is the Android Activity's lifecycle.
So, for better underestanding, The developer or those Application's programmers have to use something like Services which it can perform long-running operations in the background and does not provide a user interface.
And after that, you should be able to use those features together.


What is this Finder shortcut? A few days ago, my Samsung Galaxy S6 added a shortcut to "Finder" on my home screen.  I looked through my app list, and I can't find an app with that name.  What exactly is it, and how did it get added to my home screen?  If it's relevant, I'm in the US and use Sprint as my carrier.

The shortcut on my homescreen:

Where the original stock Rom is usually stored? Please, help me with the following questions:

Q1). Where is the original stock Rom of the Android device is usually stored?

Q2). Is it possible to delete the original stock Rom completely from the Android device? In case, we have already rooted the device with a different customized Rom.

Any resources, tips, guides, or short answers will be greatly appreciated.

Thanks in advance for your help!

Note: My device is Huawei Honor 7 - PLK-L01.

This is based entirely off @Firelord's comment, with some modifications, so all credits go to him.

First things first, the stock ROM is not as such stored anywhere on device in a form which the device can use to recover itself in case of some catastrophic software failure, such as a botched OTA.

Now, as to how stock ROMs are stored for distribution, that is an entirely different issue. The method of ROM distribution or loading onto devices vary from OEM to OEM, even carrier to carrier. We find 3 common types of ROM distributions:

ROM image files (700-1400MB): These are like Windows System Images, as such being a logical bit-for-bit copy of an on-device partition, which can be written to the device's NAND storage by a flashtool such as fastboot, nvflash or SPFT, while the device is tethered to a PC/Mac. These are usually distributed as archives, but cannot be flashed as such, they need to be decompressed separately before flashing.
ROM zip files (250-600MB): These are also system images in essence, but they are compressed and lack some model-specific or device-specific partition images to lower distribution size as these are installed, in compressed form, on-device via the device's recovery. Some manufacturers do this, but this is commonly the distribution format for custom ROMs.
ROM OTA zip files (4-200MB): These are like ROM zip files, but instead of having all the system images in the zip, these contain image patch files. They are also installed via recovery. This method helps in reducing update file size to meagre amounts when major system changes are not involved in the update.

When we talk about custom ROMs, only methods 2 and 3 are important. Only some for some Cyanogen OS devices does CyanogenMod provide ROM images for fastboot flashing.

Well, now you could wipe your device's /system partition, but note that while installing the custom ROM you already did that, and so there isn't a stock ROM on device to speak of. Wiping /system now would remove your custom ROM which you had installed, and then you would have to flash either a stock or custom ROM to make the device usable again.

Note something here: Stock recoveries cannot flash custom ROMs as the custom ROMs do not have the digital signatures that the recovery verifies before flashing them.

Similarly, custom recoveries such as CWM or TWRP cannot flash stock ROM zips as the zip checks for the integrity or stock nature of the device, which has been compromised by the presence of the custom recovery itself.

How can I unlock my Samsung S5 after too many wrong finger prints? I have a Samsung S5 with a finger print lock.

After so many attempts (5) it locked and asked for an alternate password which, unfortunately, I did not set up.

Now I cant unlock my phone. I called my server and they advised me to go on here.

I understand how difficult is this situation. I would suggest few options , either you can go for factory reset try this :

shut down your device.
press volume UP+home+ power buttons all together.

This will take you to options where you could find factory reset option. Press volume button to scroll and power to confirm. Unfortunately it will erase up everything.

Or log-in your phone from google account. Hope it helps.


Prevent unwanted automatic phone call Before anyone tries to dismiss this question, I know of a identical thread, but that question is too specific about a certain behavior following a user interaction with the phone.

I am in search of a general explanation and solution!

The phone of my 11 yo child is a Huawei P8 Light, which made an automatic call, without any interaction beforehands. At 6 a.m. today my wife heard voices and thought she is crazy, but she could locate it. She picked it up, removed the loading cable and saw, that the child's phone called someone of the contact list!

My child cannot install anything without a technical permission (Google Family Link). Before I gave the phone to the child, it was wiped and reset by myself to factory settings. All updates are installed, including firmware updates.

What exactly does cause this behavior and how do I prevent it by some setting?

I do understand technical explanations (I am developer).

There is a far yet distinct possibility that this may be a screen touch issue. Does the phone open and close, etc. other apps too? If so, we may be dealing with a touch issue on the screen.

Another instance that I have experienced is: my friend had a phone that acted up random things when the phone was charging, meaning that when it was connected to a power source, be it a laptop or its original charger, the phone would do random things when on the table (without anyone touching it).

Also, as a third possibility, please perform a "clear cache" for the "phone" app in the "apps" list in your settings.


Galaxy Note is getting slower and less responsive I've had my Galaxy Note about 18 months. It's progressively getting slower and slower to respond to user input. Any tap has an unpredictable delay, up to a few seconds. Even typing has a noticeable lag to it. I frequently accidentally tap things twice because there's no response to the first tap.

Is there anything I can do? I'd happily completely wipe and start over at this point. It's at the stage where I barely use it for things like quickly looking up stuff on the net - it's just too tedious.

It's the stock Samsung Android 4.1.2. 350 MB free on the internal storage out of 2GB, 830MB free out of 11GB on the USB storage, and 1.7/14.7GB free on the memory card.

Any suggestions gratefully received.

Such symptoms have often been attributed to the eMMC chip (which is in fact a small SSD that runs a flash translation layer (FTL) software). Android 4.3 added TRIM support to address this.

There exist solutions like LagFix (fstrim) that run on rooted devices and essentially do the same. Cyanogenmod's Wiki has more information on buggy eMMC chips.

However note:
You may want to check your eMMC type first with eMMC Brickbug Check first, to see if you have a known buggy type (where TRIM support is probably faulty).

Some background here, some Samsung eMMC chips are known to cause trouble (they're used in other brands too):

3 Questions regarding restoring the backup of whatsapp from Google Drive My phone Lenovo K53a48 stopped working on the 7th of June. I have a backup of all my WhatsApp messages until the 6th of June on Googe Drive. I installed WhatsApp on an Xperia M2. After I signed in with my phone number the question about if I want to restore my backup from my Google Drive came up. However, it required 9,3GB and the phone has a total internal memory of 8GB. I then bought a memory card of 32GB and put in inside my phone. However, the same message appears, so I understand there is no option to restore and save my WhatsApp history on the memory card. Could you confirm that, please?

Furthermore, If I uninstall the WhatsApp application now, do I have the option to install it on the memory card and so restore my backup on the memory card where there is plenty of space?

Finally, the last question. If I uninstall now WhatsApp without choosing to restore the backup but also without selecting the opposite, will I have the option to do it the next time I install WhatsApp or is it now or never?

Thank you very much for your help!!

Leo

so I understand there is no option to restore and save my WhatsApp history on the memory card. Could you confirm that, please?

Like any other apps, it is possible to save Whatsapp on the memory card. If whatsapp is installed on the internal storage, then its default location is the internal storage. If it is installed on the SD card, then it saves everything on the SD card.

  If I uninstall the WhatsApp application now, do I have the option to install it on the memory card and so restore my backup on the memory card where there is plenty of space?

Yes. If your phone allows for the installation of apps on the SD card, then there won't be any problem.

  If I uninstall now WhatsApp without choosing to restore the backup but also without selecting the opposite, will I have the option to do it the next time I install WhatsApp or is it now or never?

What do you mean by "If I uninstall now WhatsApp without choosing to restore the backup but also without selecting the opposite"?

When you unistall Whatsapp, the backups are still present in Google Drive. If you then install the app again, it will ask you to restore them.
However, note that:

  Every time you create a Google Drive backup using the same Google account, the previous Google Drive backup will be overwritten. There's no way to restore an older Google Drive backup.


Purchasing sd card will solve "insufficient memory storage" issue? After unsuccesfully rooting my android 4.1.1 tab,I can't download anny apps even though I still have 4 gb of
free memory on my internal storage.

I've done factory resetting but it didn work,will inserting an sd card possibly resolve my concern?

Can I restore apps I lost by doing this?

Buying a new SD card will not solve the problem. In Android phones, all applications are installed in internal memory. Some apps/games which ask for big data to be downloaded from the net also save the data in internal memory. So, if you insert external memory card in your device, then still you face same problem.

To solve this, first you need a external SD card; at least 8GB more would be better. Then, you need to configure your device so that it forcibly installs all data on external SD card. For more information, read this.


How can I turn on text to speech in Android? I'm not an Android user and I'm stumped. I've got a friend who wants to turn on text-to-speech on his new phone.

His old phone has a "speech" icon on the screen. When he taps that and then taps text, the text is read out loud. In the screen shot below, the "speech" icon appears near the bottom of the screen between the Música and myMetro apps.

I can't find a way to turn this option on on his new Android phone. Even worse, I haven't been able to find that "speech" icon anywhere on the internet. What is that and how do I turn it on? Help!

Found it! The option is "Select to Speak" but it wasn't available in the version of Google TalkBack installed on the phone. I had to download a new version of Google TalkBack and then the option was there. Thanks to "kirodge" for pointing me to TalkBack.
