Samsung Ace 4 Unable to charge message, but it does still charge
I have a problems with my phone. The phone dropped and since then I got an issue with charging it. When I plug in the charging cable I get the following message:

"Unable to charge. Charging paused. Battery temperature too low."

The Battery Sign on the screen is blinking, but the percentage will not go up. When I unplug it after lets say an hour it still shows the same, but when I either plug in the cable again or restart the phone, the percentage will suddenly go up. So it shows me that it charged, but it does not show it while it is charging nor when I unplug the cable and it keeps coming with the above Error Message. I assume that the USB port is still fine otherwise it would not charge, but what could be the problem?

battery drain when phone idle
I'm using LG G4 H818 with android 6.0 All of the sudden my battery started to get drained when I'm not using it at all, mostly over night.
For example, it goes from 100% to 45% over night when I turned off pretty much everything like wifi, data, location, sync etc.

When I turn on the flight mode, everything looks good and I may lose only 2% of my battery, except I can't get calls and since I should be on call for work, that's not a good option.

I have also installed some battery usage app and top processes related are:

android/OS

system/android/log.d

I also changed battery in case my previous battery was broken, this doesn't helped either.

Today, I did a factory reset, wiped cache partition and of course there is no app installed and still the same.

And, one more thing, my phone gets hot while using/charging, but not when I'm using it. Any suggestion about how to fix this issue?

Android 5.1 full phone encryption stuck 12+ hours in
Similar thread to this one.

None of the answers were helpful.

It's an unrooted Android 5.1.

The device has been factory reset.

Once I begin the encryption process, screen is stuck with displaying bare android logo:

Seen pictures on the internet with some progress indication, which is missing in my case, so something must be up:

The phone does not overheat, so the encryption clearly hasn't begun.

I'm able to cancel the process by holding power button for 10s.

Once rebooted, the system is untouched, just as it was before the encryption attempt.

Retried the process with $ adb logcat active on USB.

Nothing suspicious in the logs, although I don't know what to look for too.

Meta: Will delete the link with logs and paste only relevant lines once there's a working solution.

I have cheap phone (apparently) working on Android 7.1, I wish to erase everything to the hardware level and load the phone with a fresh OS
Background:

I have a USD $30 Chinese Android Phone made by a company called BlackZone, I have never heard of the company, the phone comes loaded with Android 7.1 Nougat which i believe is a little too fishy since it is nothing like the Nougat versions i have used and the storage shows folders with Chinese names which have permissions to access all data including location SIM information Network Information (seems to have root privilege). I think the hardware is usable though. I wish to erase everything from the phone to the hardware level and rebuild the phone using a verified version of Android. I have never worked in this domain before and do not know the way forward other than rooting the phone which also doesnt seem to be working. Could you fine people teach and guide me in the way forward.

Required Help

1.root the phone. (i have tried Kingo root, doesnt seem to be working)

2.Remove OS and Kernels

3.Reconfigure kernels and the ports available

4.Reinstall OS

P.S - it would also help if you could guide me to appropriate tags so that this question may reach the actual target audiance.

I am open to providing any and all information required.

How to Proceed after failed Rooting Attempt
aim: install LineageOS on the phone.

I tried to root the phone using the suggested sony method.

fast boot worked, the connection was given, the result was correct.

still, i had no root rights. so I couldn't go into recovery mode.

adb has the connection to the phone. I am able to reboot the phone with the command "adb reboot recovery" from my computer but doesn't go into recovery mode.

i tried to run "adb root" in the terminal on my ubuntu, didnt work either. so I tried the "adbd insure" app, didn't work because i had no root rights.

then again i tried the sony method of giving me root rights and the result said that it is unnecessary because it is already a rooted phone.

in the "phone info" on the g3311 the option "OEM-unlocking" is grey and unavailable to change.

afterwards i became desprite and switched to windows: tried towelroot, kingo root and oneclickroot. towelroot and oneclickroot said they arent currently supporting the version. kingo root just said that it failed.

How can i access root rights in order to install another operating system on the sony L1?

How can I access the Recovery Mode, other than with the ["press down volume" and boot] or [terminal-wise "adb reboot recovery"] methods?

BLU Advance 5.0 HD: Unknown apps source: androidrbx, mfn, swak news
On my year-old BLU Advance 5.0 HD phone (running Android 6.0), I recently had a few suspicious incidents where the Audio Profile seemed to have changed from Meeting to Normal on its own, and once where the phone started playing music by itself (and not anything that's on the phone). At this point, I noticed three strange entries in the apps list: "androidrbx", "mfn" and "swak news" (all lowercase), all with generic icons. I have never installed anything of the sort, and the swak news one had all kinds of app permissions, which I had not granted. I deleted all three, but they were back the next day. Repeated this for a few days then figured I had malware and did a factory restore.

On the fresh install, the only additional (Play store) apps I added were Safari Queue and Duolingo, which I hoped were fairly trustworthy. No reappearance of the above trio until today, after an update of 6 apps — 5 being Google system apps (Calculator, Keep, Android Messages, Gboard and YouTube), and the last being Duolingo. Now they are back. I foolishly did all the updates at once, so I can't pinpoint the culprit (although Duolingo obviously seems most likely, unless one of the Google apps somehow got corrupted).

So now I'm trying to gather some intel from those who have more experience with the platform before I continue on the tedious process of trying to isolate the offending app or update. (If there are better forums, please point me there.) My main question is whether this is known malware, or at least has the hallmarks of such? I have searched and found no references to any of these names (except for a seemingly legit but different Swak News app), which surprised me, but perhaps the names are randomly generated. If these are legitimate "helper" apps or something, I would like to know to which app they belong, but they seem awfully suspicious to be such.

Android 7 - How to save new contacts to the phone
I have an Android 7.1.1 phone. Before I linked it to a Google account, new contacts would be saved to the phone itself (I think SIM card was also an option).

Now That I've added my Google account, I no longer see "Phone" as a save option. I am forced to save contacts to my Google account (see screenshot).

Before I added the Google account, the Contact app setting below was unset. Now I cannot deselect Google.

Sending audio from phone to computer
I'm trying to record audio played by a phone by routing it through a computer running Windows 7. Specifically, I want to record voicemails playing from a Galaxy Note 4, which I was trying to do by playing the audio through the computer and recording with Audacity.

I have one male-to-male 3.5mm cable. By connecting that to my computer's mic jack and the phone's headphone jack, I can get a different phone (Galaxy S6) to play through my computer's speakers and can record like I want to, no problem. Also, plugging headphones into the Note 4, the audio plays perfectly through them. So, the cable works, and the phone's jack works.

But when I plug the cable into the Note 4, only half of the audio gets sent; I hear all the high-pitched parts through the computer's speakers, and all the low-pitched parts still come through the phone. Bizarre, to say the least. I would try using a different cable, but I only have the one, and it works fine on the other phone.

The voicemails are stored on my provider's server, not the phone, so I can't just copy them through USB, and trying to record them through the phone's speakers hurts the quality too much (lot of background noise here).

Ideally, I'd like to know what could be causing this strange problem and how to fix it, but any method of saving these voicemails will be enough. Can anyone help me out?

How can an Android smartphone pretend to be a tablet? (App UI like tablets)
Smartphones have heavy restrictions, compared to tablets.

Many applications, even homescreen and lockscreen, enforce vertical rotation. http://www.quora.com/Its-2016-Why-wont-my-homescreen-and-my-lockscreen-rotate

YouTube mobile: Comments and related videos can not be browsed in horizontal view on the right display size like this on tablets:

If I use my phone via MHL-HDMi or Miracast/Screen Mirroring on an external display, vertical rotation enforcement is highly annoying.

Some applications can override rotation enforcement, but the running application still thinks it is running on a smartphone, and keeps DPi low.

How can I make an application such as YouTube think that the device appears as tablet, so that it can show a superior user interface, instead of the crippled mobile UI which nobody can stand?.

Samsung S8 always on display timeout?
For the purposes of this question, I want to clarify my terminology.

Always on display The screen feature Samsung has when the screen dimly stays on to show you stuff even when the phone screen is "off". This screen shows you simplified notifications.

Lock screen This is the screen you see that says "Swipe screen to unlock". This screen appears after hitting the power button. The always on display disappears and the lock screen appears. This screen shows you detailed notifications.

Security screen This screen appears after swiping from the lock screen. This will ask to type in the pin or enter a pattern to unlock the device.

The issue I have is the time between the lock screen and the always on display. I see I have a notification on the always on display. I'll hit the power button to go to the lock screen to read the notification. The lock screen then only stays up for 2 seconds (not exaggerating, I timed it) and then transitions back to the always on display. This is super frustrating. Trying to read a notification and boom here comes the always on display.

I have the screen timeout set for 2 minutes. I have the security lock timeout set for 5 minutes. I can't find any other settings for this.

How can I extend the amount of time the phone takes to move from the lock screen back to the always on display?

Wifi stuck in "Obtaining IP address", but connects in another area
When I am at my desk at work the Wifi does not connect to my phone and I get stuck looping in "obtaining IP address". However if I step away from my desk to another part of the building, my phone connects no problem. I noticed that if I download a large file somewhere else and get back to my desk, my phone stays connected (although at a lower signal which is fine) until the download is finished, and then switches back to "obtaining IP address". This being a work environment I don't have access to any of the routers. Is there anyway I can force my phone to connect to the router in the other part of the building? thanks.

Increasing max # of items in Firefox for Android history
A couple days ago I decided to give Firefox for Android another chance, and it turns out its history only goes back 100 items! How do I fix this? I want unlimited history, as I've set up on my Pale Moon on PC, or at least a way to backup and import, as the FEBE extension does on PC (I don't have root on my phone).

I tried the places.history.expiration.max_pages method, but it does nothing (probably because, as I gather, FF for Android doesn't use places.sqlite). Other FF Android clones I tried have the same problem.

(Frankly I'm a little disturbed by the amount of extensions aimed at deleting history. In this day and age of ubiquitous internet traffic logging, why do people want to be the only ones not to have access to their browsing history?)

2 apk files for same app
I've noticed that several of my applications have 2 apk files (different versions).  Why are there two?  And is it safe for me to delete the older one?
For example, on my phone I see:
"Google Play services for Instant Apps_1.13-release-159715800.apk" and
"Google Play services for Instant Apps_1.14-release-161844041.apk"
also:
"YouTube_12.25.54.apk" and "YouTube_12.23.60.apk"
also
"Chrome_58.0.3029.83.apk" and "Chrome_50.0.2661.89.apk"
also
"Amazon Kindle_7.15.0.73.apk" and "Amazon Kindle_7.14.0.18.apk"
and more ...
I'd like to delete the older ones.  Certainly, combined, they are taking up a lot of space on my phone.

One more question.  Not every app has 2 apk files like this.  Is there a setting to limit them all to one file?  Thanks.

Hey all, thanks for the comments.  Very good point to look where the files are.  Just some background how I got here: I usb'd my phone to my PC and searched *.* and sorted by size to find what was taking so much space on my phone's internal storage (will check my sd card next).  Saw these APK files coming up and noticed the duplicates, so I asked this question.

At any rate I've gone back now and checked where they are located and it appears that most of them are in /storage/emulated/0/SmsContactsBackup/apks/.  Based on the term "Backup" being part of the location, I'm going to assume that I can delete both copies of the apk files when both are in that directory.

Again, Thanks for the comments.  I definitely should have thought to take note of where the files were located from the start.  Any additional comments or answers as to how the apks got into that directory would be appreciated.  I'm guessing that either the install put them there, or once upon a time I ran some backup program on my phone (not something I do regularly since my most important stuff syncs to google anyway).

问:
How to remotely access an Android device from any device connected to the internet with root access?
Out of curiosity, I always wondered is it possibly to access your android device remotely, your files, start any app, run any function you will want to the same way you can do as if you were with the device physically. If it is, then how?

I'm kinda thinking if I should have the following;

IMEI

ESN

MEID

Google Account

It should be more than enough to grant me full access to my device.

Considering the IMEI is can be used to identify the device, ESN (Electronic Serial Numbers) and MEID (Mobile Equipment Identifiers) can link an individual to a phone. And with the Google account used on the device.

Since a remote desktop software lets you access your computer and all its applications over the Internet using another device, essentially by streaming a feed of your desktop. This works from a tablet or phone, even over a cellular data network, I feel an android device should be able to do same.

I have checked to see possible question;

I want to remotely control my Android device from my PC without rooting it. Is this possible?

Remotely control an Android tablet from a Mac or Windows machine?

Accessing and Controlling an Android Device Remotely

Can I remotely control an Android device using TeamViewer?

is there way to remotely turn on your android phone?

but none has fully answered the question.

NOTE: This is with the assumption that the android device has access to the internet and throughout the remote access, the device will have access to the internet. There's no restriction to the usage of just TeamViewer.

Any good answer and comment is greatly accepted on if there's an app that can actually do that or what it takes to make such kinda app. Thanks in anticipation.

Share location in WhatsApp showing map on continental scale
When I want to share my location with someone on WhatsApp, it gives me a list of places, two of them close to my home, and the third is Panama (the country! And I live in Brazil). I thought it was some cache issue on my phone, perhaps I've searched Panama in Google Maps recently, I wasn't sure. So I looked at the same option in both my father and my mother phones, and their WhatsApp have the same problem: Panama is also the third on the list. However, their app didn't zoom out to show Panama, as mine do. This is a nuisance, because I have to increase the zoom every time I want to share a different location browsing the map.

So, why is WhatsApp (or Google Maps?) so worried about Panama? And why will my phone zoom out to include this country in the visible map, while my parents' phones will not? Can I remove Panama from this list? (Or any other distant place, the other day it was a place I've never been to, in another Brazilian state.)

WhatsApp FAQ says: "Choose Location to send your location or a nearby place." I don't know why is it considering that Panama is "nearby" Brazil, but of course something is wrong here. Anyone have similar issues? Google only tells me about the "awesome new feature of live location", it doesn't matter if I included keywords such as "error", "issue", "strange behavior". Even the + that used to work behind a word to make it required doesn't work anymore...

(lesser relevant) Battery statistics. (I have ccc.bmw71.pro (does stand for battery monitor widget, not for Bayerisches MotorWerk this time.) for that purpose. But it overwrote bmw_history.txt.)

App Metadata (AndroidManifest.xml, installation date, store, usage statistic, etc.)

Settings, other metadata and usage statistics if possible, but that is lesser relevant.

Anything else. (NANDROID would require rooting.).

Data by third-party messaging applications is usually included into application data.

How to get Huawei Product ID without stock ROM?
I have Lineage as opposed to the stock ROM, so putting:

```<code>*#*#1357946#*#*
</code>```

does not work for me.

Recommended on alternate posts were downloading a program called "Huawei Product ID Generator", but this does not work for me as my device model is not an option listed (my device model is KIW-L24).

And this generator (http://www.rootjunkysdl.com/files/) does not have my phone listed either.

Do any of you know how I can get my Product ID since these three methods do not work for me?

Thank you!

Do a Fairphone 2 backup without Google-Services
I ran into some problems with my Fairphone 2 and it has to be fully replaced. So I'd like to backup my information including contacts, sms, wi-fi passwords and if possible too Whatsapp-conversations.

Now it's not like Fairphone doesn't provide a tutorial for backing up your phone. The issue is it completely relies on Google Services and means I'm going to store all kinds of private information voluntary on random Google-Servers.

As I'm also using that phone for work and university I was advised NOT to share everything with Google.

I have been trying Titanium-Backup, but for that it's necessary to root the phone. (Well, and before I do that I'd surely like to backup everything so...)

So Helium seems to be a good option. The app is downloaded and on my Linux I got the their scrips, connected my phone, opened the app and typed:

```<code>qohelet@ubuntu:~/Downloads/linux$ ./run.sh
error: device not found
</code>```

adb is installed.

I switched on the USB-Debugging as asked and it wants to use the PTP instead of the MTP (which I think I did, but nothing changed).

Installed Chrome and used Helium as a Chrome-App instead. No changes still.

I'm pretty much suck now. Fairphone doesn't offer any other support than relying on Google to solve that issue for them and I'm not aware of other backup-options.

What's the easiest way to do a backup?


问:
Disable notification sound for PingID on authentication
PingID is an authentication tool used for 2FA login, after initial login to a system it will prompt the installed app on phone to loudly beep when it is asking for authentication (by swiping a widget). Since this is used in office, I don't want to annoy others around me and nor do I need a reminder sound when I know exactly when I will be asked to use the app.

Is there a way to disable the audible prompt only for PingID (or, if you don't know about this specific app, then steps to do so for any general app)? I'd prefer methods that use existing Settings or tools if possible, but am open to installing other apps if necessary.

问:
Does MiA1 support Rescue Party?
I wanted to check if Rescue Party, a much touted feature of Oreo is active on my device ( since it is not mandated in Android Compatibility Definition Document as the linked source says)

The first step is to override USB connection (suppression) , since

All rescue events are suppressed when the device has an active USB data connection because that's a strong signal that someone is debugging the device

To do that  run

adb shell setprop persist.sys.enable_rescue 1

My device returns

setprop: failed to set property 'persist.sys.enable_rescue' to '1'

Can I conclude from this that Mi A1 doesn't support Rescue Party?
 ( some explanation would help)

Aside, this XDA thread No, Android Oreo’s Rescue Party is not the bootloop fix you were looking for gives useful details on Rescue Party ( Please note that my device is not rooted )

问:
Gmail on android - notifications for multiple users using the same account?
I have a Gmail account which accessed by multiple people. Sometimes it happens that we receive an e-mail and one of us doesn't get notified.

I'm guessing this is happening because when the e-mail arrives, if one of us gets a notification before the others and reads it too soon, then Gmail marks it read and doesn't notify other devices.

The only workaround I can think of is setting up an e-mail forward for all of us and then just disabling the notifications from the shared account.

Is there a better solution to this?

问:
Unable to free up space on internal storage, removing cache & apps has no effect
new to Android Stack Exchange. - Average Android user.

I have a storage problem on my phone. When I try to install an app via Play Store it says there isn't enough free space available, e.g. it is 45mb short. Play Store then offers an option to uninstall other apps to clear up space. So, I select a large app (of e.g. 130mb) and allow PlayStore to uninstall it. It then removes the selected up succefully. However, after doing so it still fails on installing the newly selected app, claiming again it is short on free space (still claiming to be 45mb short).

This has caused a situation in which I have deleted pretty much all my apps but Play Store still refuses to install any new app or any update because it claims to be short on space.

When I go to Settings-> Storage and USB-> Internal Storage it reports that 4.09GB out of 4.54GB is used. However, in the details below it only reports that 2.39GB is used for Apps and 5.33MB is used for cache (which I've cleared many times allready, hoping it would solve the problem). But this means that I am unable to diagnose where 4.09GB-2.39GB-5.33MB = 1.7GB of disk space is apparently being used for...

I tried connecting my phone to my laptop via USB, in order to be able to browse the internal memory but somehow when I use MTP I am only able to browse my phone's SD-storage via my laptop. The internal storage directories simply do not show up and I am left clueless on how to get any access to them..

I am looking for any insights or any tips on how to further diagnose what the problem might be..

Samsung GT-N8013 tablet listed as a GT-I9100 phone in lsusb on Linux
I have a Samsung GT-N8013 tablet in Download mode, using the stock recovery since TWRP coulnd't work (go here for more information), connected to a Linux machine. adb cannot classify my tablet as a device on Linux, so I had to follow this answer. When I found its ID, I found that it had a different name entirely:

```<code>Bus 001 Device 013: ID 04e8:685d Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II] (Download mode)
</code>```

How is this possible?

Update 23-02-2018:

I plugged in the tablet again and booted it normally. It ran into the "encryption unsuccessful" error, however I ran lsusb and it yielded

```<code>Bus 001 Device 003: ID 04e8:685c Samsung Electronics Co., Ltd GT-I9250 Phone [Galaxy Nexus] (Mass storage mode)

What's going on to the tablet?

I do also want to point out that it has LineageOS installed before I flashed the stock ROM and recovery, but it has not been working ever since.

问:
How can I get one month of battery time for an IOT application?
I like tinkering with Arduino and similar prototyping platforms for IOT applications. Often I want to read a sensor value and send it to some cloud service and repeat this, say, once every hour.

Today I realised that my old Android phone that currently lies unused in my underwear drawer has huge potential for being a powerful sensor platform.

Let's say I only want to run a single app on the phone that does the following:

```<code>1. Read sensor value (accelerometer/temperature/light/...)
2. Send value via http
3. Sleep for one hour
4. Goto 1
</code>```

Would it be possible to get one month of battery time on an Android phone running this program?

My first test would probably be to enable flight mode and uninstall as many apps as possible. Is there a better way? Maybe there is a custom ROM or similar that is specially made for this?

How to get Google voice input to "submit" / "enter"
Voice typing is convenient, having to press a keyboard button to submit or press enter is less so.

While 'native' apps like Google Assistant know when to submit according pauses or natural sentence structure, using Google voice typing in other contexts (even just the browser) doesn't automatically submit as far as I can tell.

How does one, using their voice, perform the enter/go/done action for Google voice typing in lieu of the keyboard?

问:
preventing current app from being killed while screen is off and running off AC power
Is it too much to ask to be able to start an app before I go to bed at night, turn off the screen, and then turn the screen back on in the middle of the night and have it still there, undisturbed?  Instead, after 4-5 hours of inactivity there is a good chance that the app will be killed!  Why does Android even do this?  It can't be for power saving, because the device is plugged in all night (battery charged), and it can't be for speeding up the device because nothing else is running (aside from a few CPU seconds an hour for push notification checks), or for dealing with running out of memory because the device in question has 3GB and almost 600MB is being reported as free.  The app is not even in the background, so if the app explicitly foregrounds itself it doesn't really fix the issue.

Even with apps that do a good job of saving their current state and restoring it after being killed (and most do not) it's still a pain because the app is no longer on the screen so it has to be located and started, and then it takes a bit of time for it to for initialization code.  During the middle of the night is a very inopportune time to have to do this!

In older versions of Android there were certain hacks you could do to the underlying Linux proc or sys filesystems to try to combat this problem.  There is an existing question but it is nearly seven years old.  But now I am running the latest version of Android (8.1) and I'm wondering about the current state of the art in solving this problem.


问:
Why does installing applications freeze my DroidX running Froyo 2.2?
I noticed recently that installing any applications caused my Droid X (Stock rooted Froyo 2.2) to freeze for a while - I mean completely freeze, can't go to home screen or pull down Notification bar or anything.

It may possibly be correllated time-wise with installing Lookout Security app, but I am not certain if the time matches.

This seems to be 100% unrelated to a specific installer application I use, but I haven't conclusively ruled it out.

Could this plausibly be caused by Lookout? If so I'll try to un-install it to verify

If it's caused by Lookout, are there any suggestions for making this less painful? I was thinking along the lines of loweing "nice" priority for Lookout scanner process somehow if Android allows that, being based on Linux.

If not Lookout, what else could it possibly be and what troubleshooting steps can I take short of flashing back to SBF and trying to install my apps again from backup?

Details:

Rooted Stock Froyo 2.2 on DroidX.

Source of installation is irrelevant (Android Market, or Amazon Market, or GetJar). I didn't test SD/Dropbox APK installs, but fairly certain that they are freezing as well.

I have several installer apps available, but default to stock one. I don't know how to un-default it to test if it's a specific installer.

As noted, I have Lookout Security running, set to scan any installed .apks.

It is possible that the freezing didn't happen or was much quicker before I installed it, but I don't have proof. Also, installing NUMEROUS updates of Lookout didn't affect the freezing.

Freezing is 100% independent on what else is running - I can kill 100% of non-Market apps and the freezing will still happen with almost full memory available

Freeze period seems to be correllated to .apk size, but I don't have a firm proof. Usually lasts between 30 secs and 2 mins.

This seems to be NOT related to having to start other apps (e.g. Amazon Market/GetJar) that are started by "Application Installed"/"Application changed" intents, since the freeze happens for EVERY app installed among several, not just the first one in a row.

Android doesn't delete folders completely
Redmi 3s, MIUI 9.2 MultiROM Stable. I had some music on SD card in Music folder, then I deleted it (using Poweramp or file explorer, same for both). Tried to send music from PC using Foobar2000 extension OneWaySync but get error

One way sync failed: Error: Could not create directory on WPD device. Another item with the name \Redmi 3S\Samsung SD card\music\Bob Dylan might exist already, or check permissions.

Then I tried to create folder Bob Dylan manually from PC, but nothing happened, only sound to indicate that it failed. If I create folder manually via file explorer on the phone, then it appears (sometimes with errors already exists), I delete it, and finally I am able to sync normally. However, there are way to many folders to recreate by myself, so I am looking for some easier method to remove folders from Android completely.

Can not disable Software Update application
I have an older Android phone and recently updated to Android v5. Since the update I keep receiving a notification on my screen to update the software again (it also automatically downloads a 250mb file). This update however has no effect (it keeps re-installing the same version). I am therefore looking for a way to disable it.

A previous post on this site suggested to go to the Application Manager > All > Software Updater and then subsequently to Disable the app and clear the cache.

I did this but it had no effect. In fact it made things more complex:

I have now two Software Updater apps (one is v3.19 which I cannot disable, and the other is v4.2 which I turned off)

After disabling v3.19, I cannot do anything anymore when opening it. It is not turned off and all buttons are disabled (see screenshot below).

Moto Z Play Won't boot after SuperSU install
My Moto Z Play boot process won't finish. I can get to the Fastboot screen by powering off and pressing Power+Volume Down, but can't boot into Recovery Mode or Factory Mode. Both start the normal boot cycle which doesn't seem to finish. Powering off the device just restarts it. Even holding the power button for 10+ seconds doesn't power off, it just restarts the boot process.

Steps:

I unlocked the boot loader per Motorola instructions

Installed ADB and Fastboot to my laptop

Installed TWRP

Installed SuperSU. SuperSU kept going back to "Root Undetected" so I attempted a wipe to start fresh

Now the device attempts to boot as if wiped, which I can tell because when the Z Play boots after a factory reset it plays a "Hello Moto" clip. But the boot process doesn't finish. The same happens if I try to boot to recovery mode. Also, ADB doesn't show the device as attached anymore.

Is there any way of recovering the device, or am I buying a new one?

Can't retrieve contacts from a locked HTC 300
So... here's the story. My father had his HTC Desire 300 for ages and he stored all of his contacts on the phone, not on the SIM card. One day, my unreasonably curious mother wanted to unlock it and she locked the phone because she attempted to guess the pattern way too many times.

It would've been easy to unlock it if only my father knew his gmail account info. I tried all sorts of combinations, he's an older fella so I figured I could maybe brute force it, but to no avail.

To make things even worse, the phone isn't even rooted. He got a new phone, but he wanted me to salvage his photos and contacts. I managed to pull all the photos using adb, but I just can't find a way to extract his contacts. I tried everything but I always bump into issues with permissions, since the phone isn't rooted and there's no custom recovery and the bootloader is locked.

Logged in, sending a message does NOT work, and calling DOES work after reinstall
NOTHING has changed since I tried UN-installing and RE-installing Skype from scratch of the Android 5.0 Note 3.  Except NOW, the CONTACTS are only showing from one contact, which is really odd.  Seems NO contacts or ALL contacts should have shown up.  When I tired to log in with my account, using the same app, ALL my contacts showed up immediately.

All VOICE calls work flawlessly, TO or FROM.

Any MESSAGES fail, TO or FROM.

When trying to send a message from the phone, it never gets
past the circle and "sending" indicator.

Yesterday, I noticed that my wife's android Skype didn't send or receive the messages I sent or should have received.  Tried calling the phone using Skype, that did work.  Also tried sending and receiving a message to/from her phone, WHILE on the call.  Messages never worked at all.

Separately, I tried this while logged into BOTH a web based Skype UI, AND the Windows (desktop) installed Skype.  Messages from me or to me worked, as long as they didn't originate or should have been received on the phone.

The problem must not be her account, nor any settings, nor any interference from another logged in Skype session on any other device.  Although I haven't tried logging into her account on my phone, I doubt if there will be a problem.  The problem is obviously isolated to JUST her phone.  I DID try to log into MY account on her phone, but all my contacts and messages showed up, and sending and receiving worked flawlessly on her phone.

It appears that there must be TWO modules -- with separate logins...

Voice, which logs in and works.

Messages, which doesn't, since it is not logged in, but only failed to log in with HER account.


问:
Correct approach to symlink or mount bind two directories on internal storage
I have data from an app I would like to be synced. It writes into a directory, and and has no settings for what dir.
I would like it to write to a different dir, one that is synced.

I'm on a nexus 5x, running stock 8.1.0 fully updated.
I have root.
I'm trying to make things written to /storage/self/primary/sleep-data go to /storage/self/primary/sync/phone/sleep-data

ln -s doesn't work, I'm thinking a filesystem issue, though looking through the output of mount it wasn't clear what the filesystem actually is. /storage/self is mounted as tmpfs.

mount -o bind /storage/self/primary/sleep-data /storage/self/primary/sync/phone/sleep-data

This works, but only as root.

I did try mount -o bind,shared with and without namespace seperation set in supersu, as suggested by Rob W

I suspect it's related to this: How to "mount --bind" directories in Android 4.4?

That does have a workaround, but it's looking like I'm approaching this the wrong way.

That seems to be related to external SD cards only.

Voice control of audio playback: seek within track
I'm planning a lengthy cycling trip and I'd like to be able to listen to language training mp3s while riding.  I think the ideal way to do this would be to use voice control.  Is there a way that will let me

seek back eg 10 seconds

seek back 1 minute

repeat a section of, say 1 minute duration

seek ahead 10s, 1m, etc

skip to next/previous track

pause/resume playback

via voice commands?

For bonus points, I'd like it to let me set a bookmark at a certain point in a given file and then seek to that spot via voice command.

Can I disable SMS ID?
I received a phishing text yesterday that purported to be from "NatwestUK". That in itself isn't entirely surprising; what bothered me was how easy it apparently is for any scam artist to use a service to disguise the number their text messages are being sent from. I want to know the number of anyone who contacts me; any system designed to hide this information seems thoroughly anti-consumer.

Is this something users have the ability to disable via software? Can my network (O2 UK) do it for me? Is it simply not possible in any manner due to how the system works?

Problem with simultaneously connection in game (NavyField Mobile)

Can you flash directly from another Android (no PC, no SD)?
I have an old Android TV box (the ZaapTV 509N) that is useless. It was advertised as a $300 subscription-free streaming service for Arabic channels from overseas, but every 3 years they would force a $300 hardware upgrade on you, and now that they've run out of new upgrades, you need a subscription to continue using the device with their service.

The device is running their custom Android ROM on it (4.2.2), and it is pretty locked down. You cannot add a Google account to use the marketplace to install useful apps like YouTube or Netflix. I've been looking at what other custom ROMs I could flash on it to regain control of my device, just installing YouTube and Netflix on it would make this device useful again. I've found 3 candidate ROMs for this, from similar streaming devices with very similar hardware.

I've flashed phones before (ported ROM from a different letter iteration of the same model or straight out CyanogenMod), and all these needed me to connect the Android device to a laptop. With the ZaapTV, the only USB ports are female, so I would need a male A to male A USB cable to connect to a laptop. The only male to male USB cables I have are micro at one end and regular size at the other.

So, I could connect an Android phone to the ZaapTV device. If I move the required ROM to my phone's storage, is it feasible to use my phone instead of a laptop to flash the ZaapTV? Is there an app or a flash utility that is available to do what ODIN and ADB are doing on the laptop?

I do have access to the recovery menu on the ZaapTV. I also have a Raspberry Pi (running Raspbian, a port of Debian). It has an OTG micro-USB. Could that work?

Without Adbd insecure installed and ticked both phones behave the same in Droid Explorer for PC. i.e.I can't access the data folder and I can't modify files or folders. When I install Adbd insecure and apply the patch to the Cubot it works perfectly. Droid explorer has full access and the consol prompt changes from a $ to a #. However, if I install Adbd insecure on the Doogee and apply the patch I immediately lose all connection with the phone. It shows up in Device manager as unknown device with a code 43 error. I can't reconnect to it until I have removed the patch and re-booted the phone.

How to remove Play-store notification "uninstall harmful app"? (kit-kat)
About a year ago I rooted my Verizon tablet with King root - which is working fine. Then when Google Play Protect came out, it started giving me this static notification telling me to uninstall King root and it kept on popping up even though I unchecked the "scan apps installed from unknown sources box". It started to annoy me a lot so I just turned off the play store notifications.

How to install apps to SD with adb when SD is formatted as internal storage

Now when I adb install -s whatever.apk it fails with

```<code>java.lang.IllegalStateException: ☃No suitable external storage available

But when I leave the -s away the apps go to the true internal storage, rapidly filling it up.

Even this attempt at a workaround failed:

```<code>adb push whatever.apk /storage/self/primary/
adb shell pm set-install-location 2 # this works, get-install-location returns external afterwards
adb shell pm install /storage/self/primary/whatever.apk

They still don't go to the SD card.

Note that I'm talking about apps which support external storage, i.e. those I can move to the SD card from the settings menu.

How to avoid icon-within-icon when using "Add to Home screen"
With some apps like Chrome and the Google app it's possible to add shortcuts to content by using "Add to home screen". Unfortunately the icons created for these shortcuts have a small app icon placed over the lower right corner of the image representing the content. This makes things unnecessarily complicated and ugly on the home screen. I'm trying to find a way to easily avoid these icons-within-icons.

For example if you search for "weather" in the Google app, then select the first result, then select "Add to home screen" in that content's three-bars menu, you get a shortcut to the current weather on your home screen. Similarly, if you go to news.bbc.co.uk in Chrome and select "Add to Home screen" in that tab's three-dots menu you get a shortcut to BBC News on your home screen.

The resulting icons will look like this:

The microphone-over-cloud-over-sun is a particularly egregious mixed metaphor and visual mess, but even for content that has a simpler image like BBC News the icon-within-icon is ugly and unnecessary. After all, I created these shortcuts myself so I know which apps they will open, and if I ever forget I only have to tap on the shortcut to be reminded... I certainly don't need to be reminded by visual clutter every time I view my home screen.

The icons-within-icons get created whether I use the Google Now Launcher which is the default on my Nexus phone or or whether I use an alternative home app like the Nova Launcher. With the Nova Launcher I could manually change the icons to what I want after I create the shortcuts, but to do that I'd need an unadulterated version of the icon representing the shortcut's content, and those are not always readily available. For example I haven't yet found the Google app's weather icon without the microphone, and even the BBC News logo seems to only be available as a rectangle that would need to be resized and cropped to be used as an icon. I'm trying to avoid having to do such manual edits to get the shortcut icons I need: After all, the system itself has access to the desired icons since it's able to disfigure them by overlaying its app-icon-in-the-corner :-).

Thanks in advance for any help you can provide.

Battery Level Instant Drop
Recently, muy phone has had several instances of instant battery level drop; not as in quick drain, but rather, immediate drop. I've been able to document these two occurrences :

Between the first and second occurrence, I uninstalled apps that were using data on the background (such as games and whatnot), I monitored the battery usage per application, disabled unused applications, and used motorola's app battery optimization. And while doing all that did in fact improved my overall battery life, that didn't prevent it from "spontaneously" dropping to near 0%.

Also, I  noticed  that in both cases, there was a slight increment in battery level, before dying (It was charging but I had to unplug it to attend a call).

Finally, there was no significant phone or battery heating that I could perceive.

Another sympton, although I'm unsure this is related in any way, is that my phone turned off, as if battery completely depleted, while having battery level at 15:

I've tried wiping my cache partition, and hasn't occurred since; however, I think that this might be purely coincidental.

My phone information:

I have not been able to find this question repeated here on SE.

Internal Storage Increase / Replace
I am not convinced that My Spotify is using an entire 1GB on my new Android.

I am new to Mobile Phones, but they seem to follow the basic laws and rules of Computer Science and Telecommunication. I can not understand how 200 songs downloaded in standard quality on Spotify can use a full 1024 Mb on the phone when on my laptop the same number of songs use only 343.8 Mb.
 I have cleared App data Caches, uninstalled Apps I am not using and my internal storage on my phone is still 7.50Gb out of 8 Gb.

I understand the internal storage package is most likely on a BGA so removing it is not an option.
 However is it possible to put a 128GB SD in an Alcatel U5 Android Phone, and then partition the 8 Gb of Internal Storage as a system reserved, for the Android OS? Then Partition the SD as ext2 and default it to App user data.

My concern with doing this is, one I have never taken a phone apart so I do not know how the hardware is arranged, two I bought this phone 3 days ago, it still has a warranty and I don't want to void the warranty and three I do not want to have to install extra Apps to do this as I am still learning the Android OS.

I would like to know how to do this with a windows laptop, as I can get an SD Reader, and also where the SD card is inserted into the phone when ready.

Any instructions on the general procedure or specific procedure for doing this would be greatly appreciated.

Thank you.

Note 8 lock screen PIN differs from startup?
I'm trying to fix a Note 8 that seems to be in a weird state. The correct PIN should be 4 digits. The lock screen won't accept the PIN (the OK button stays greyed out until I hit 6 digits, at which time it reports that the pin is invalid). But it seems to be the correct pin, as it works to decrypt the phone on startup.

The phone user says the only unusual thing they did before the problem occurred was to reset their Secure Folder password. They said that they were able to get into Secure Folder after the reset. Their secure folder password does not work to unlock the lock screen. Later, after the screen turned off, they were unable to unlock the phone.

I'm totally mystified. Can the startup and lock screen pins be different? If they can, can the problem be corrected somehow, or does the phone need to be reset?

Using an Android phone as a wifi headset for Windows
Here is the issue:

I am working from home and want to use my wired headset on both my work computer and personal computer (not at the same time) without having to plug/unplug it every time

I prefer wifi over Bluetooth because of superior range and bandwidth

I have an old Galaxy Note4 and would like to plug my headset into it and be able to switch from one PC to the other

I have found solutions allowing to use the phone as a webcam or mic which would cover half of my needs (DroidCam...) and apps that send audio from the Windows PC to the phone (SoundIt...) but no app allowing to do both at the same time from a single app.
I could potentially use Windows "Listen" functionalities to create bridges between a VOIP client and the main sound card on the PC but this is a bit tedious and I am concerned this might add unnecessary latency.

Ideally, my dream app would:
- Create sound devices for playback and recording on the PC

Have a server app on the PC forwarding audio between the client on the phone and the local audio devices (allowing me to dial from the PC using Skype or other solution and get sound to/from my phone)

Have a client app on Android that would send mic and receive speaker audio of the phone to/from the selected server.

While it seems like a rather easy thing to implement, I cannot find any satisfactory solution. Any suggestion?

Availability of security patches for Meltdown and Spectre on Pixel
The security vulnerabilities Meltdown and Spectre are referenced as CVE-2017-5753, CVE-2017-5715 and CVE-2017-5754. Those three variants can be gathered under the more general case CVE-2017-13218 (source).

It is said in the Android security bulletin from January, 2018 that the security patch level 2018-01-05 contains the fix for CVE-2017-13218. According to it, this has been dealt with in the Kernel components, which are binaries. For those, the bulletin says: "The update for that issue is generally contained in the latest binary drivers for Nexus devices available from the Google Developer site". The Kernel is distributed as a binary, and consequently it is not possible to check if the security patch is actually contained in it. On the Google Developer site, the last release available for Pixel Android 7.1.1 (because that's what interests me here) is NOF27D. However this release is already dated from April, 2017. Moreover, the code name of the release (NOF27D) had already been set way before that in platform/build (February, that would be the release 35 of Android 7.1.1).

Hence my question: is the security patch level for Meltdown and Spectre included into the last release of Pixel Android 7.1.1 available currently (NOF27D)?

If yes, does that mean Google has had a patch ready for those issues more than a year ago? If no, where can I find the security patch?

How do I find APN settings to use with a 3rd party SMS app?
I'm using an admittedly old (Android 4.0.4) Samsung Galaxy Centura (Tracfone) and I've run into a problem with regards to text messaging. The default "Messaging" app is quite limited and is missing the one thing that I wanted:(group messaging), so I switched to Textra for messaging. Textra is almost perfect, except that it won't send or receive an MMS!

I figured it was a simple matter of updating the APN settings, until Tracfone support informed me that this phone "does not have adustable APN settings," and could not help me any further.

I experimented and found that the stock Messaging app can send/receive MMS, so it's not a system-wide problem, just a Textra problem. I experimented with a couple of other SMS apps from the Play Store, and they all exhibit the same symptoms. SMS works fine, but MMS fails.

Textra does have a place to input custom APN settings, but I can't seem to find the proper settings anywhere. I googled "APN settings for tracfone" and tried a couple of the common results, but no go. I did find out that the phone is apparently running on the Verizon network, (the gateways ##########@vtext.com and ##########@mypixmessages both work) so I tried Verizon APN settings too, but to no avail.

Any ideas on what steps to take next? Surely it is possible, I'm just missing a piece of the puzzle somewhere. :|

I tried to uninstall Samsung Gear app and install it again with google play. It worked for few days but after that I have the above problem again

I use the option of "Connect to new phone" on my watch. It factory reset the watch and connected my watch to phone. But again after a few days I have the above problem.

Will leaving a device on an NFC tag do any harm?
I want to leave my phone sat on an NFC tag all day long - will it do any harm to either the phone or the tag?

I'm worried about Android constantly trying to read the tag all day, and that this could cause unecessary battery use, the tag could get hot from constantly being read, etc etc.

Is there anything to back up these concerns, or is it fine to leave a device on an NFC tag for a long period of time? Will Android read the tag over and over again, or does it somehow know when it's placed on a new tag?

Note the device is a Samsung Galaxy S7 (Android 7.0) and the tag is one of the cheap 'NFC stickers' you can get from amazon etc.

Edit: not a dupe of the linked question because that only asks about battery drain. This question is about adverse affects in general (e.g. over heating the tag).

问:
Galaxy Note 4 Battery Drain, Have Been Able to Narrow Cause Down to SD Card. Suggestions?
I've had my Galaxy Note 4 AT&T model for a little over a month now.  I got it pre-owned, but even so it works great, almost as if brand new.  With the exception of the battery life.

I've noticed drain ever since I first powered the phone on.  Going through the initial setup and then just experimenting around with the interface for about 25-30 minutes led to 26% of battery lost.  The screen brightness was 25%, and there was not even a SIM card in the phone at the time, so it could not be attributed to any cell connectivity.  Also I can't blame any apps that were installed, as there were no apps installed by me yet.  In fact, after disabling about half of the built in bloatware I knew I would never use, I still didn't see any battery improvement.

Since then, just to give you an idea, it drains an average of 10% overnight, and this is with the app tray cleared, screen off, and airplane mode on (Wi-Fi off too).  Now, I know this phone is four years old and perhaps the processor and other components require more power than they used to, but that can't be normal.

I also did a video streaming battery test.  At almost no brightness and no other background apps running, I got almost exactly 2h30 of streaming YouTube videos in HD.  In contrast, a fellow YouTuber got 6h23 with the brightness at max.

I know this is not the battery.  The battery that came with the phone that I know is genuine Samsung, a brand new battery ordered directly from Samsung, and a third battery (that I'm not sure if it's genuine Samsung) all have the same drain problem.  Also note that none of the batteries do anything crazy, like "jump" percentages or die unexpectedly before the phone reaches 1%; the drainage is pretty consistent and always goes from 100% to 0%.  It's just that this happens too rapidly.

I've gone into the Battery section of Settings multiple times once the battery has gone below 20% from a 100% charge, and it always says that the screen is the thing taking the most power (around 10-12%), then the Android System following with about half of what the screen was using, then Cell Standby and Android System tied at around 2-3%.  Underneath that, any apps I was using are listed, at 1%.  In total, the whole listing doesn't even nearly add up to 100%; not sure if that's normal either.  I typically use the phone with 30% screen brightness unless outside, and the "Auto Adjust Screen Tone" setting is always on.

I've been able to narrow the problem down to the Micro SD card reader part.  I've had a 128 GB Sandisk Ultra in the phone since I got it.  But I've also used this same card in my previous phone (a Samsung Galaxy Luna), and there were no battery issues at all.  I also don't use it as an integral part of the phone's functionality (I don't store apps on it), it is only used to hold my music library and the photos/videos I take with the phone's camera.

I tried once to remove the SD card, put it in my PC and fully reformat it using the official SD reformat tool, then put it back in the phone (obviously I backed up the files).  This briefly fixed the battery drain, but after a few days it went right back to the way it was.

As another experiment, I removed the SD card and charged the phone to 100%, and didn't put the card back in.  Running the phone with no SD card so far has given the greatest success I've had with solving the issue; I got more than double the amount of time on a charge.

The only thing I can think of is that the Note 4, in its official spec sheet, only can accept up to a 64 GB card, and I'm using it with a 128 GB.  But other people on forums don't seem to be having battery issues.  I've also seen suggestions to update the firmware, but I do not use my phone under a major carrier's service, so updating is not an option.  It seems to be running the latest firmware anyway:  it's on 6.0.1.  Some have suggested to try the Greenify app; this seemed to help a little at first but that could have been placebo.  Ultimately I uninstalled it after a week.

I suppose I could just carry around extra batteries everywhere I go, or keep removing the SD card when I'm not listening to music or filming, but it's so small that I wouldn't want to risk losing or corrupting it.  I'm willing to live with this because the Note 4 is such a nice phone in every other regard, but does anyone have any other suggestions before I give up?  I would even consider rooting and installing a custom ROM, but I would like for this to be my absolute last resort if at all possible.  Let me know if you have any more questions; I'll be sure to give more information.

WhatsApp Chat Backup crashed. Any restoration guides?
Yesterday night I had checked that my phone having a free space of less than 300 MB, but was totally fine. My WhatsApp Messenger is configured to back up everyday at 2:00 am (I am in the United Kingdom, GMT / UTC Time Zone +0:00 Hours). Today it so happened, when it tried to make a local backup of messages at 2 am (when I was asleep), it failed and looks like it even removed the current message store.

It informed that there was some error with the backup and if I would like to restore the chat history, and it can be done only once. I had to hopelessly say Yes, as the messages are really important and when I did, boom it restored the chats till February 8th, 2018 till 2:00 am GMT.

Current Situation: Whatever between February 8th, 2018 till 2:00 am GMT and February 9th, 2018 till 7:00 am GMT are missing and I am unable to find where the WhatsApp Database is stored.

My questions are:

Is it possible to get back my lost messages during the lost period of February 8th, 2018 till 2:00 am GMT to February 9th, 2018 till 7:00 am GMT?

Where does WhatsApp store its current msgstore.db.crypt12 file, as all I see in the Databases directory is backup?

My phone details:

Software: Android 6.0

Model: Lava X81

Free Space: 300 MB

WhatsApp

Version: 2.18.9

Backup Frequency: Everyday at 2:00 am GMT.

Online Backup: None

SD Card: None

How to turn mobile hotspot off using ADB
I need to turn the mobile hotspot off using ADB. I'm using various Samsung phones with Android 7 & 8.

I'm planning on opening the settings activity and using keyevents. I know the Mobile Hotspot and Tethering settings page is com.android.setting/.TetherSettings but beneath that there is a Mobile Hotspot page. Does anyone know how to open that page with ADB?

I'm open to alternative methods of turning mobile hotspot on and off with ADB.

Suggested solution in How to turn on the wi-fi hotspot using ADB? does not work for the phones I've got.

On Android 7 and earlier you can achieve the desired result by turning on Wifi (which automatically disables the hotspot) and then turning Wifi off again. However Android 8 thwarts this by popping up a warning dialog which has to be dismissed.

Airpods w Android: on calls bluetooth constantly connects/disconnects
HTC 10, Android 7.0

Works great for music playback, but on calls it continuously connects/disconnects the bluetooth.

So using the airpods are useless for calling.

I have tried unpairing/repairing, and turning off/on the "phone" option on the bluetooth settings.

This issue is widely reported on the web, with android generally. For example here: https://forums.oneplus.net/threads/apple-airpods-connection-issue.497047/

This vlogger says to use just one ear of the airpods for calls when using android.  https://youtu.be/YUI4aZ1Uer8   My first pass testing indicates that using one ear is indeed a work around (though audio quality was poor, not sure if as a result of the single side)

How to diagnose/resolve?
