Manually (Re-)Encrypting a Whatsapp Backup File

Problem

So, after rooting using a custom ROM and rooting my phone somehow WhatsApp wont let me back up my chat history anymore, see below. The problem now is that I want to transfer my chat history from my old phone to a new one.

.

Alternative Plan

From what I've gathered WhatsApp Backup files are crypt12 encrypted msgstore.db files that are located at the root directory /data/data/com.whatsapp

Things I have:

Old Backup from a few months ago

my current unencrypted msgstore.db through root access

crypt12 key file through root access

My plan now is to basically create a new backup by encrypting my current msgstore.db and transfering that to the new phone, hopefully recovering my chats. The only thing I need is a way to reencrypt the file to be the same as a WhatsApp Backup File. Or just modifying my existing, old backup with the new content. Is this possible?

How can I reinstall basically everything on an LG G2
I don't know what happened, to be honest, it was a couple of years ago.
I rooted my LG D802 with TWRP. Because I was young and dumb and had no idea what I was doing, I decided to wipe the whole storage. Literally nothing is left except TWRP 2.7.0

My questions might sound dumb, maybe, i dont know, but here goes:
First off: Where do i get the files? Literally anything that is remotely related to an operating system is entirely gone. So i would literally have to install everything down to the metal. I remember trying to just flash a ROM back then, but that hasnt helped. Recently, i came to the conclusion, that it might be the missing kernel? Maybe im talking absolute nonsense, but i still havent really looked into that matter and im just trying to get my old phone back as a backup phone.
What would I need to get this working again? Is it possible at all? I have the Drivers and ADB Tools installed, but none of that has had an effect, flashing anything just fails miserably.

Restoring from files, not backup
My oneplus2 recently got stuck in a bootloop after years of usage. Despite all my attempts of flashing the rom again with or without root + custom kernel, it didn't boot. So I moved all my internal storage (every folder) to my pc by connecting it via usb while it was in recovery mode. Then I factory reset, still didn't work. I had to wipe data (not internal storage) as well then flash the rom after to get the phone to boot. My question is, can I restore app data (and potentially the apps as well) ?

Phone doesn't see SDCard after doing 2nd partition
In this topic I mentioned that I'm going to change a phone. And it happened. I bought new SDCard and inserted it into new phone. My new Samsung saw this card perfectly. Using MiniTool Partition Wizard I made a 2nd partition for Link2SD. Before partitioning there was 16MB unallocated memory at the beginning and 59,6GB Primary exFAT partition (I bought 64GB card). After partitioning I have 51,6GB Primary exFAT partition (1st partition for music, images etc.) and 8,0GB Primary EXT2 partition (2nd partition for apps). After partitioning my phone can't see the card completely. Just like it hasn't be inserted. But after returning to old partition everything works fine again. How to fix it?

How to tell what adb is parsing
I am trying to get adb working on an aarch64 board. The actual binary runs, it just always shows that the devices are always empty.

I know for a fact the device is working because I have a second, statically linked adb binary from https://github.com/hduong85/arm_adb that works (but is too large for our specs). This binary needs zero config to detect the usb device. I could delete /etc/udev/rules.d and it would still find the device.

I got a much smaller one from https://launchpad.net/ubuntu/xenial/arm64/android-tools-adb

And it runs, but the devices are always empty.

I tried editing /etc/udev/rules.d/50-android.rules, 51-android.rules, 70-android.rules, ~/.android/adb_usb.ini, you name it, nothing helps.

The problem is, I have no idea if adb is even using/parsing these sources of information. It never complains about anything. How can I tell?

And what's up with the android_usb gadget that I see some places where you set configs in /sys/class/android_usb? Our board is running linux 4.4 and does not have the android usb gadget driver. Why is adb so fragmented on how to config it?

Any debug tips welcome!

Xiaomi TWRP error 255 flashing lineage
Hey guys i recently bought an Xiaomi Mi A1.
The OS needs 8GB plus much goggle on it (I hate google) so I decided to flash a custom rom. I figured some how out how to boot and afterwards flash the TWRP recovery (Version 3.1.1 By Mohan CM-Mi A1). Through TWRP I want to flash Lineage OS which throw the error 255. Confused with this, I tried different TWRPs, ROMs and also formated all partitions exept recovery and boot (so I formatted Data, Cache and Dalvik, System, and Internal Storage) and even tried sideload. None Worked... so now I have no system to boot on and dont know what to do to get Lineage running.

SOLUTION:
The lineage wiki always links the TWRP they are using in the tutorial (Mi A1: https://wiki.lineageos.org/devices/tissot/install)
which also links to an TWRP build. This build should normally work.

How to exit Meta Mode boot loop?

In Meta Mode, I can connect it with ADB, but I can't do anything, because it's unauthorized:

```<code>$ adb devices

Apps not recognizing Bluetooth presence (especially the mic)
I have a good BT headset. It pairs without issue to my phone which has stock Android 7.0. Audio plays fine through the BT headset but for some reason the mic function is not properly recognized. I tested with Easy Voice Recorder. When I switch to record to with BT in that app, it says it can't recognize BT device. But it is clearly recording through BT (I left the phone in one room, and went to another room and whispered into my BT and it recorded it fine).
Any ideas what's going on here? I can live with this functionality in this app, but I use another app called TextNow (for VOIP calling) and it also doesn't recognize the BT and there's no workaround there.

Phone: Moto G5

On the other hand I do can access android but by entering to fastboot mode and then selecting normal startup, if I do that, Android starts just fine, but, every time I power off the phone and start it again like that, Android optimizes all apps (as if it were the first time Android is running). My question is, how can I set Android to boot when I power on the phone instead of TWRP? thanks in advance</p>

Nissan keeps losing Bluetooth connectivity to my phone
I originally posted a version of this question to mechanics.stackexchange, under the assumption that something was wrong w/ my 2013 Nissan Altima SV.  However, it sounds like it's an issue that only affects Android phones, not iPhones or Windows phones.

My car offers Bluetooth connectivity, and that feature worked great for about a year; for phonecalls, podcasts, and music.

However, for some time now, when I start my car and navigate to AUX to listen to my phone, it occasionally says, "No devices connected". When I navigate through the menus to look at Bluetooth devices, the car still has my phone listed in its devices, it's just unable to connect.

When this happens, I have to delete my phone from the list of devices, and re-add it. Then, it will work fine for another week or two, before the same problem occurs.

I have a Google Pixel (first generation).  Is this a known issue with Android Bluetooth functionality?

Almost anything Google related keeps stopping
My wife's Pixel just started behaving oddly this evening.  Virtually all Google related services keep force closing with the error message "_____ has stopped" or "_____ keeps stopping".  There are various different apps and services that fill in the "blank".

Google

Settings

Google Play Services

Device Health Check

Google Keyboard

Additionally other Google apps, such as Google Maps, do not launch when started.  It just returns to the home screen without an error message. And when she tries to open Google Play, all she gets is a white screen.

A common suggestion I've seen both here and other sites is to clear the system cache, unfortunately she is running Android 8.1 so that setting doesn't exist.  Additionally because Settings force closes upon launching, I am unable to do it for the individual apps (besides, which app do I clear).  Another is to reinstall the Google Play services, but I'm unable to do so because Google Play closes when I open it as well as does settings so I can't roll it back there.

Since this started all of a sudden as soon as she returned home today, I'm assuming there is a bad update somewhere, but since I can't get into Google Play or the Setting to see the app details, I can't uninstall or reinstall.

I've tried booting into Safe Mode and I get the same error messages, so that won't be a help.

There were no apps installed recently, and if it helps, many 3rd party apps and games appear to work fine.

As pointed out in the comments, a factory reset would seem to be an option, but I consider that the "nuclear option" that I'm trying to avoid since it involves a lot of backing up and restoring that I don't want to go through.

note 3 and note 8
Are you aware of any issues with the Note 8 phones giving hot-spot access to the devices nearby if the note version you got is from another country or region? Does Samsung have restrictions still?

You may ask why I am asking such a question, and what the rationale is.
What prompts me to this question is the following experience I got.

I used note-3 (for years while I lived in in the US. ). No issues. But, when I brought it to Turkey, and put in a TURKCELL LTE simcard, I learned that it cannot give hotspot to my devices. (Whereas the iPhone 6plus which I also used and brought from the US ) does not have this issue with the Turkish Carriers.

Now I'm about to purchase a note 8 from Dubai (to use it in Turkey with TURKCELL ).  I'd like to make sure that if I put the Turkish sim card in it, I will be able to create a hot spot and my laptop will be available get its internet thru the note.

Do you have any information about any issues with hot-spot with note phones? Or is this an issue of the past?

Also, what could be the cause of not-giving-hot-spot access. As far as I remember, I believe USB & Bluetooth options did not work either.

Can you install an app in a secure silo?
So I am learning Chinese and - because Google is not available in China - Chinese apps tend to be downloaded outside of the play store. To that end, a lot of news apps (especially the good ones which are offered by the state news organisations, e.g. CCTV) have ridiculously wide-ranging security-access levels (i.e. you have to agree that they can read your contacts, your accounts, camera access, the works - even though it has no logical need for such access).
Obviously, not too keen on giving the Chinese government full access to spy on me for the benefit of a news app, but is there a way of setting up a secure silo within Android, in which you can then install apps and dictate what access they can have?
In some respects, I would like to set up a Great Firewall of Europe on my phone and put the Chinese apps (or at least the ones which seem to come with added surveillance functionality) in there to stop them unnecessarily getting at my contacts etc.
Your help would be greatly appreciated!

How to enable usb debugging and install an apk to an android device with non-functioning display?
The display of my Xperia z3 is non-functioning(i.e. all I can see is a black screen) after an accidental damage due to water-insertion. But all other parts are working fine. The screen responses to touch, I can hear the touch sounds and I can click photographs as well with the camera key.

After connecting the phone with USB cable to my ubuntu laptop, I can browse through the internal storage files on the phone and locate the newly created image files as I click new photographs and take screen-shots. But I can't open any files(images/audio/videos) with errors like "couldn't load image" and "couldn't determine type of stream". However, I'm able to copy new files to the internal storage.

I want to install some screencasting application like vysor on my phone so that I can access it using my laptop. I know this can be done using adb commands but the problem here is that USB debugging is not enabled on my phone and hence I can't find it on the list of adb devices.

Is there any workaround for such situation?

Bluetooth with Moto G4
I recently purchased a Motorola Moto G4. My husband has the LG wireless headphones. I tried to pair but every time I would get a phone call the voices would come over garbled like they were under water. I thought it was the headsets due to I also fought this with my last phone LG Phenix 2, so i went and bought another pair. These are called Warrior BT2. When I finished charging them up i paired them and made a phone call, same problem. i was ok as long as i held the phone but if i even went 1 ft from the phone it would cause issues. Where i live I don't have great service so when i find service i have to leave my phone in that spot. What can I do to fix this or do I need to go purchase the higher end ear phones? my husband's was 70 dollars and i still fight this. Please help</p>

问:
All files of the internal memory are duplicated on an LG G6
I have an LG G6 (has Android 7.1. An update with Android 8.0 is announced but not avaliable yet) with an SD card. The SD card went corrupt for some reason and after a phone restart, all files in the internal memory are listed twice. Somehow, a virtual folder named /sdcard/ (locaded at /storage/emulated/) is created and just mirrors the internal memory. I did a factory reset and the problem was fixed, but the SD card went corrupt again and the issue re-emerged. Is there a way to fix it without having to do a factory reset again? I'm not sure if it is completely related to the existence of the actual SD card either.</p>

问:
Move apps to the SD card and keep them there
I have a phone with a very small internal memory (LG K7, just 4GB storage, running Android 5.1.1) but a nice roomy (64 GB) external SD card, so naturally I use an application manager (specifically, AppManager III) to move as many apps as possible to my external storage.  For the most part, it works fine.

But every time one of these apps updates the new version is (by default) installed in my internal storage, and I have to move it again.  This happens at least 2-3 times per week, especially for apps like Facebook, Twitter and Messenger, which update very, very frequently.

It's very frustrating to have to manually instruct my phone over and over again that, yes, I want to move the app to external storage again.  Is there a way to just set this once and forget about it?  One option, I guess, would be to turn off auto-updates.  But what I really want is a way to configure things so that the auto-updates are auto-moved to the external storage each time they are re-installed.  Particularly looking for methods that don't require rooting my phone.

问:
How to rid Contacts app of phone numbers showing as duplicate entries
Problem description:

This is the typical duplicate contacts scenario where a contact name does not show up when being called by that number. The problem is, named contacts have been duplicated into their phone number formatted counterparts. This has seemingly been caused by WhatsApp as only contacts with WhatsApp have been duplicated.

I.E., at the time the duplication occurred, Contacts app had 600 named contacts which "automatically" duplicated into 470 numbered contacts. Therefore, 1070 contacts exist, with no way to merge.

Research and solution attempts:

Contacts > Settings > Merge duplicate contacts, produces no result

Contacts > Settings > Contacts to Display > Custom List > Deselect WhatsApp contacts, shows only the named contacts but still doesn't show the named contact when being called.

Syncing the contacts to Google, only syncs the named contacts, so merging cannot happen there

Refreshing contacts in WhatsApp produces no result

Other information:

CLI (Caller Line Identity) is turned on and had always worked prior to the issue arising - most notably if a named contact does not have WhatsApp, the contact name shows when being called currently.

Samsung Galaxy S6 Edge with Android version 7.0

Partial Working Solution:

Deleting numbered contacts 1 by 1, produces "You cannot delete contacts from read-only accounts, but you can hide them in contacts." [Cancel] [Delete]

Clicking [Delete] does produce the desired result but I'm looking for a more elegant fix. For lack of better words, to merge all named contacts and numbered contacts, without deleting them 1 by 1.

Disable "com.package.name has stopped" pop-up notification
I am typing, and then, a pop-up flies into the screen, telling me that a random application in the background has halted.

Starting with Android Lollipop, the "OK" button of the pop-up is terribly small, and is greyed out for one second. Tapping on the background behind the pop-up does not work.

Apparently, Android is unable to send a notification instead of pop-up on app crashes, so it decides to block the screen like the infamous iOS volume indicator.

How do I disable the app crash pop-up?

Shell: get battery voltage_now if power were not connected
I am trying to make my device stop charging (echo 0 > /sys/class/power_supply/battery/charging_enabled, the easy part) when the battery's voltage reaches 3920000 µV.

Using cat /sys/class/power_supply/battery/voltage_now or dumpsys battery, I can also tell that the battery is at a certain voltage, like 3916000 (in µV). When the device is not charging, this number is the battery's charge voltage, the number I want. However, when the device is connected to a charger (DC out is normally 5V), this value is neither the battery's voltage, nor the input voltage, but some value in between, because of how charging works.

Because the voltage_now does not reflect the battery's rest voltage when charging, and this number is dependent on which charger I use, I cannot obtain the number I need (3920000) whenever the device should stop charging. So apart from pulse charging and sampling, how should I get the battery's non-charging voltage from the shell while charging?

Note: "manually calculating the battery percentage when the voltage is 3.92V, and then stopping charging when /sys/class/power_supply/battery/capacity reaches that number" is not a satisfactory answer or workaround.

Voice typing in Android for a disabled person with very limited hand function
I have a close friend who is suffering from a neurological disorder similar to ALS (Lou Gehrig's disease).  Over the last year his arms, hands and fingers have weakened greatly to the point where he can no longer type or hold a pen.  He is a writer.  As yet we cannot afford expensive assistive technologies or a full time assistant, so I have been trying to use an Android tablet to help him write via Voice Typing.

He writes in Hindi.

We have done some experiments combining the tablet with an external keyboard that he keeps on a tray (with the tablet on a desk), since lifting his hand up to tap on the screen or to hold the tablet tires him out quickly.  The goal of our experiments is to reduce the need to tap the screen to an absolute minimum.  Using this app we have set up a key on the keyboard to start voice typing, so he no longer has to tap to start it.    However, I have some questions:

Voice typing will sometimes stop and ask you to tap the microphone icon to start it again.  As far as I can see this seems random but happens every one or two minutes.  The external keyboard key has no effect on this and he has to lift his hand to tap the microphone icon.  Why does this happen?  Is there a way this can be reduced?  Alternatively, is there some other method that will allow a tap on a key to restart voice typing without needing to tap the screen?

Are there any guides to how to speak most effectively for dictation to Voice Typing (e.g. which is best - full sentences at a slow speed, full sentences at a normal speed, a few words at a time, or some other combination?)?

At times voice typing will seem to "jam" and simply stop writing anything - even though the microphone icon is red and it seems to be hearing.  After a minute it may start to write a lot, or it may just seem to hang, and restarting it requires tapping it once to stop it and then again to start it.  The tablet is an old machine (3 years old) that is extremely low end - Android 4.4. running on 1 GB RAM.  Is this a result of the low end nature of the tablet?

Is there a way to allow external keyboard typing in a language other than English (i.e. similar to the Gboard's phonetic entry for other languages)? He can use this for a few corrections to the frequent mistakes that Voice Typing makes (we'll ask someone else to clean up the final text, however).

I hope there are ways around these things - it is crushing to watch a major literary writer lose his ability to write.... If I'm barking up the wrong tree entirely and you all have suggestions on better methods, that would also be great.

How does memory usage compare on Droid X Froyo vs Gingerbread stock ROMs?
If I upgrade my Droid X from Froyo 2.2 stock to Gingerbread 2.3 stock Motorola/Verizon ROM, is it known what the memory footprint impact is expected to be? (assuming I keep my installed app list and usage patterns identical)

For example, if my stock Froyo 2.2 ROM boots up with ~170MB memory free, and during my day to day use I end up with ~50-70MB memory free (this is with ALL my actively used apps loaded, and Android not killing any of them to make room for others), what would the expected memory footprint be on a stock Verizon OTA updated Gingerbread ROM?

Please note that the question is specific to MotoBlurry stock Droid X ROMs, though I would appreciate a good statistical comparisons of AOSP 2.2 vs 2.3 as well - but for the latter, I'm completely not interested in subjective one-person accounts, just large scale statistics.


问:
mac address collision

The setting:

I have two identical phones: Samsung Galaxy S5 neo (SM-G903F). Due to various reasons (in one I tried Lineage OS, the other I had to reinstall) and crashed backups made by TWRP I ended up having to flash stock ROM to both of them. I installed the latest same image downloaded from https://www.sammobile.com/firmwares/galaxy-s5-neo/SM-G903F/

The ROM is NOT rooted, the Knox reports no flags - just as if it was a freshly bought phone.

The problem:

After a while I discovered that both of them have the same MAC address and therefore I cannot have them both connected to my home WiFi at the same time - both are assigned same IP address by router and in the end none of them has access to the internet. However, one connection at the time works.

Same goes with bluetooth pairing - when I connect one phone to a speaker and then disconnects, I cannot then pair the other phone with same speaker.

Questions:

How is that even possible? I thought MAC address is tied to hardware not ROM? Is there other possible cause? I didn't have this problem before I started flashing.

How can I solve the problem of assigning same IP?

I'm aware of MAC spoofers. Nonetheless, is there an option that doesn't require rooting?

limit app search to apps only in android 8
I have a google pixel 1 that I recently updated from android 7 to android 8.

In both android 7 and 8 I can drag upwards from the bottom of the home screen to go into a view that shows all apps. At the top of this view there is a search bar.

In android 7 if I entered some text in this search bar it would search my list of installed apps for ones whose names contain the search term. In android 8 it shows me all sorts of noisy web and other search results above the list of matching apps.

For example, if I search for 'ca' it shows me a web result for a film called 'call me by your name' and a contact from my contacts list named 'Carl', and a couple of other web search results. Underneath all this noise is where it shows the apps that start with 'ca': calculator, calendar, camera.

Does anyone know how to configure this search to only search the list of installed apps? I use this search all the time and I find the noise distracting and annoying.

Phone only turns on when it's plugged in but then works normally
The problem regards a cheap 5.1-based Android phone, manufactured by a company named Manta. A few days ago it randomly shut off on its own and it was impossible to turn it on because it got stuck on the producer's logo every single time. I tried all the usual stuff like ejecting the SIM, the memory card, wiping cache from the recovery menu - all to no avail. Suddenly, I found a way to turn it on - namely, if you try to turn it on unplugged, you may leave it for a few hours and it won't go past the producer's splash screen. Try to turn it on when plugged in the charger, though - and it'll power up within 30 seconds to the home screen and keep working with no problems whatsoever.

Normally I would think that it's caused by something battery related - but the thing is, it doesn't seem so. First, if you try to turn it on unplugged and leave it on that never ending splash screen, it'll hold its charge alright, not turn off after a minute. And more importantly, second - if you plug it in, turn it on and unplug it - it'll keep working perfectly until you have to turn it off or restart it. What may be the problem, then? Is there anything I may try to do to fix the issue and allow it to turn on when unplugged as well?

S7 Edge Messaging App Cannot Block a number that is not a contact
I can block a number that is a contact such as my mum. But I cannot block numbers by companies such as my network proviser Three. By block I mean stop receiving annoying text messages,

It is not Three I am trying to block just using them as an example. I cannot add three to contact to perform block options that does not work. What is even more infuriating is that I cannot find a number to block its just "Three" with no phone number to be discovered anywhere.

How can I block these annoying text messages that are not even in my phones contacts.

Can I use my Android device to find out which FM frequency has the least noise?
I have an Android device (Nougat) with a built in FM reciever.

I also have an FM transmitter that I use to transmit audio to my car stereo. As I travel around, I find that the landscape of FM real radio
transmissions differs. I want to be on the frequency  with the least noise (regular transmissions) so that I can get the least disturbance for my own signal.

There are some services where I could look this up online, or I could just do it by trial and error, but as I travel around this gets inconvenient.

I know that dedicated hardware exits to automatically find the FM frequency with the least noise with one click, but I figure my phone already has the hardware to do it. Can I do it with my Android phone?

I have root and Xposed Framework, if it matters.

stock sms client creates multiple threads for the same number
Running the default android SMS application, multiple threads get created for the same number.

This is how it started: I was visiting a foreign country, I got a legit sms from the service provider (smartone in Hong Kong) suggesting that I could get cheaper calls by dialing *131*001 followed by country code and number. I tried it on an sms to see if it would work. It didn't but from then on the sms app started two threads, in a seemingly random way: most of the received sms are listed under a number starting with *131*001 that I cannot reply to. In the process all the past sms conversations were "captured" and listed under that number. To send sms I had to start a new thread with the same number but without *131*001.

This is what I tried: first, I added *131*001etc as an additional number for my contact, hoping that the threads would be merged. But it did nothing.

Secondly, after reading some, I used SMSBackupAndRestore to save the sms and modify the resulting xml file. I noticed one difference between the sms in the two different threads, namely, a difference in the service_center, for instance service_center="+852161645501" for the sms listed as *131*001etc and service_center="null" for the properly listed sms. So I replaced every instance of service_center="+852161645501" (numbers varied) with service_center="null". I then reloaded the modified xml file using SMSBackupAndRestore.

Before the "fix" just described, I had about 2,000 messages listed under *131*001etc and about 5 or 6 listed under the correct number. After the "fix", I had two more or less evenly split lists, of about 1,000 messages each. Plus a third list got created with 2 messages in it.

As I was doing this, it occurred to me that SMSBackupAndRestore only saves the text of the sms, not the pictures and other attachments. Yet, the pictures and attachments were showing up after applying the "fix", showing that the sms had not really been deleted, merely taken off the directory and upon being re-loaded the android sms app would "recognize" the messages and re-load the pictures and attachments. This means that there is a folder somewhere with the history of my sms. And the android sms app is using information stored there to recreate the *131*001etc thread that I'm trying to delete.

I wanted to delete all the cache. I couldn't find it by browsing (I'm using Windows 7), so I downloaded some apps to help me, two apps named 1tap cleaner, both worked in a similar way and deleted cache, but obviously not the cache I want to delete since it hasn't solved anything.

I have deleted all the sms, but double threads listed as *131*001etc still happen with the new messages. Plus now I can't even add a picture to my contacts (when I "edit" the contact, I can only edit the name and number, nothing else)...

Handcent hasn't helped.

Any suggestions on how to get out of this nightmare? many thanks.

"Sync is currently experiencing problems. It will be back shortly "
I just got my S8 yesterday and everything is pretty much smooth sailing except for the fact that I cannot sign in into my school's gmail account. I've searched high and low online, following almost everything I could.

I've noticed that when I try to sign in again online, it says that Chrome has requested a certificate and that you can install certificates from a pkcs#12 file with a .pfx or a .p12 extension. It gives me an option to Install or Cancel but whenever I try to install it gives me a blank document with nothing to install.

Then, when I am on the Google Docs app and signed in with my account, it says to refresh the page because it says "Unable to refresh. Check your network connection then swip down to retry". I swipe down, and a window that says Checking Info.. appears for a brief second and then disappears.

I cleared the cache of the gmail app, rebooted my phone, wiped my phone, reinstalled the app, followed these with no success.

How can I fix my hotspot?
I'm on a Google Pixel XL, stock, unrooted. Android 8.1.0, build OPM1.171019.021
My Carrier is T-Mobile, via Straight talk BYOP program.

I was able to hotspot (WiFi tethering) without any trouble at all. Then one day my computer lost connection to my hotspot, so I checked my phone, and it was off. Turning it back on, I had a notification that said "Your phone shut off due to heat." It didn't feel hot at the time, compared to other times that I've used it and it felt warm to the touch. Since then, I'm unable to connect through tethering.

Built in WiFi Hotspot and USB tether give the same problem.

A few things I've found:
When connection another phone, it authenticates, then says "Connected, No Internet"
On a Linux machine, when I ping google.com it can resolve Google's IP address, but has 100% packet loss.
On a Mac, PDANet app allowed me to get online, though I need to be able to WiFi hotspot without PDANet.
When using a WiFi file transfer app, I'm able to connect to the hotspot and transfer files to/from the phone without any problems.

A few things I've tried:
-Reboot phone
-Contact Carrier to check/reset data settings on their end
-Reset APN settings
-Factory reset phone
-Replace SIM card

What can I do to get this fixed? It was fine for a long time, then suddenly, this happens and nothing seems to fix it.

Also, the SE websites confuse me, so I have no idea which one to ask this on. I've asked Android specific questions on Android SE and was closed for being off topic. If possible, please just tell me where to ask or migrate my question instead of flagging it. I don't know where to ask about this sort of thing, and I prefer the SE community over other Q&A sites where I can only get the opinion of trolls. Thanks.

Phone shows no dialogue when I try to adb backup Huawei Ascend G620S Android 4.4.4 EMUI 2.3
I have an Huawei Ascend G620S-L01 with Android 4.4.4 and EMUI 2.3.
I'd like to make a full backup of the system in case something goes wrong when I try to root it later, so that I have a safe backup to restore to.

I enabled USB-Debugging in the phone's Developer Option and chose a password for the backup.

Then I got myself Android Studio and installed the Google USB Driver with help of the SDK Manager.

In the CMD I went to C:\Users\NAME\AppData\Local\Android\Sdk\platform-tools.

I connected my phone with my PC, chose the USB mass storage mode (though MTP doesn't make any differences, I tried that too). When I choose the option that the phone should just load, it won't even be recognized by adb devices.

Now, when I enter adb devices it shows my device, at least it gives some digits and letters on the left and it says "device" on the right.

Now I enter:
adb backup –all -apk -shared –f c:\backup\backup.ab
I also tried
adb backup '-all -apk -shared -f c:\backup\backup.ab'

The answer is the same:
Now unlock your device and confirm the backup operation...

But on my phone, nothing happens. No dialogue appears.

C:\backup just shows a file with 0KB named backup.ab

CMD shows again that I'm in my platform-tools folder and waits for a new order.

I also tried using adb-1.0.31-windows, didn't change anything for me.

I hope someone can help me and guide me into making a full backup.

Thanks in advance for your support!


问:
presumably faulty battery level reading in Android 6.0 on an LG G4
I have been recently experiencing battery level drops, and to my understanding my observations may have not been documented in the same way earlier by other users. The phenomenon is similar to what was reported by another usere here, or here although with some differences.

There is apparently no single app that drains more energy and that is causing the battery drop.

The battery level tends to fall rapidly only when it's down to about 40% or below, but not any 'earlier'.

When the phone shuts down, it sort of carries the information that the battery level is null, and for this reason one cannot turn on the phone again. When re-charging, the battery level reportedly rises to about 2-3% and only at this point the phone can be turned on again. When the OS is fully loaded, the battery indication gets back to a good 50-70%. This seems to be a genuine reading since the phone can stay on for quite some time even after 'immediate' unplugging.

I wonder whether an option is a factory reset, though one does wonder whether there is a cause to this and if it can be addressed.

Android version is is 6.0, security patch level 2016-07-01, kernel 3.10.84.
The Phone is an LG G4. Not rooted, untouched.

Reopen app to last activity
If I open an app from a link (e.g. a notification or a link from an SMS), every subsequent time I open the app from the history, it goes back to the same link, performing actions I don't want it to and making me have to shut down the extra page / press back to clear the subitem(s). It becomes necessary to force-close the app and reopen it from the apps list to get the default behaviour back.

It there a way that when an app goes to sleep and is woken up again, it resumes from where it left off, and not from the last link used to open it?

EDIT

Some people are having trouble understanding the issue, so step by step:

Open an app from a notification or a link

Read the message, take any appropriate action, etc. then use the app normally, navigating away from the notification area

Wait half an hour or long enough for the OS to put the app to sleep

Open the recent tasks list

Select the app again to wake it up

Instead of the app remembering its last state (which it does when opened from the installed apps list), it reopens as if the notification had been clicked again.

I haven't noticed any apps that don't do this. Opera, Facebook, Duolingo, etc. It's on Android 7.0.

How to tell which Xposed modules will break OTA updates?
I have Xiaomi MiA1 which being an Android one device gets monthly security updates

One can root it with Magisk and install systemless Xposed 1 . So far, good. My problem is with Xposed modules and not the framework since it's systemless.

Some modules likes adaway write to the hosts files in /system , so that will break OTA. Quoting from Magisk on Github

NOTE: In order to apply OTAs, you HAVE to make sure you haven't modified /system (and /vendor if available) in anyway, even remounting the partition to rw will tamper block verification!!

I am pretty confused

1 Magisk with it's modules passes CTS checks and with Xposed fails as is documented. So I plan to disable Xposed before updating to pass CTS and get OTA. There are ways of doing this and yet get OTA which I intend to try

Archiving or Exporting SMS Group Messages
How do you export/archive SMS messages received from a group?

Are they stored in some other database separate from all other SMS messages?

I have a Samsung Galaxy S7, and the stock SMS app.

I have several (all the free ones) SMS archival apps, and I notice that messages that I received because they were sent to a group are never included in these archives.

This became most obvious when I received 200+ messages of a conversation between two people, and I was part of that group. I wanted to archive the conversation and it only shows up as 3 messages. Only the ones sent explicitly to me, not any of the other 200 messages.

These messages appear just like all other messages. There is no way for me to distinguish the fact that they were sent to a group and not just myself (except for being told that they weren't texting me in error... I was part of the group).

EDIT

After working on this for some time. I have noticed that the messages to the group are MMS (multimedia messages).

This likely changes the focus of the question.

After going back to stock ROM from an unstable custom ROM, my Galaxy S6 keeps freezing
I own a Samsung Galaxy S6. I used NNE 5.1 S8 port and it was working well until it got my phone broken somehow.

My phone started acting really strange after 2 months of activity of that new ROM, my phone just started restarting randomly and it got me worried, i thought it's an application problem so i first just factory resetted it. It seemed it was not the problem on an application, so i chose to change my firmware to a stock one. I searched up recently on the newest firmware for S6 and i found out it's: XEF (France) , PDA (AP): G920FXXU6ERC1 and CSC : G920FOXA6ERC1 on 2018-03-22. I Downloaded 4 files: BL,AP,CP,CSC , and i found out about PIT on one of the posts in XDA forum (Filename: SM-G920F-ZEROFLTE_EUR_OPEN.pit).

Before i flashed with Odin, i wiped System, Data, Cache and Dalvik Cache. The firmware worked well but after 1 hour it started doing the same thing but now differently. It happened to me only 1 time that it froze up on an application, but i think that is just an app problem. It isn't actually the app fault, it freezes a while after it boots up. The main problem is that when i lock my screen, i cannot unlock it anymore, it just freezes there until it restarts after a short period of time. After the restart, it just keeps going, restarts, asks for pin, restarts and so on.
I tried removing the sim card and putting it back in, did not work.

Understanding Excessive Battery Drain on Note 8 (Nougat 7.1.1)
I'm suffering from excessive battery drains on Note 8, Nougat 7.1.1. The battery drain is excessive when on idle mode/when the phone is asleep. I have installed BetterBatteryStats (gave it all permissions) and tested with different settings for a couple days.

My findings:

I strongly believe the issue is with my wifi.

Day 1: I kept wifi on, turned off "adaptive wifi" and "wifi power saving mode" and set "keep wifi on during sleep" to always. Battery drain was very excessive at home. In BBS, wlan_rx_wake and powermanagerservice.wakelocks were very high and phone didn't doze much. When I left home and went to the library and was connected to my school's wifi, the phone dozed, and the two wakelocks mentioned didn't occur any more. In fact, from the screenshot you can see the two flat regions are those when I was at the library, and the downhill regions are when I was home.

Day 2: I kept wifi on, turned on "adaptive wifi" and "wifi power saving mode" and set "keep wifi on during sleep" to never. No change. The results were just like day 1. Excessive wakelocks and battery drain. In fact, funny enough, the wakelocks occurred more often as if "wifi power saving mode" was doing the opposite of what it was supposed to.

Day 3: I turned off wifi completely, and was on cellular the whole time. Battery performance was amazing. Lost 5% over 10 hours, and I actually used the phone during this time. I made calls, surfed the web and texted. Additionally, the are no excessive wakelocks, and the battery plot is nearly flat the whole time.

In conclusion, I am really confused. At home, wifi kills my battery. At school, wifi doesn't do anything weird. It makes me feel like this is more than just some setting on the phone or some bug with Nougat. Maybe some networking issues with my wifi at home? At any rate, I seem to have found the problem. But I was hoping I could get some insight as to why this is happening. Additionally, I'm wondering if there is a fix, because I would like to use wifi instead of cellular the whole time.

Notes

I was at home, I had wifi turned off, and during this time I experienced great battery life (~4-5% every 12-14 hours). Then, I turned on wifi just to test things, and the battery life noticeably got worse. I'm talking ~1% drain every hour. I turned it back off.

For those wondering, I experience wifi-related battery drain even if Wifi-Calling is off, so it's not that. Also, I have factory reset many many times so that is not a solution either.

Rooting Samsung Galaxy S II GT-i9100 (follow on Q'n)
I'm a newbie to digging into Android this deep, so please bear with me. FYI I'm more familiar with PC's, with a smattering of the back office side of things from muddling along. So any response couched in familiar terms would be welcome.

I'm in the same situation as this: Rooting Samsung Galaxy S II GT-i9100, which I've read along with the associated comments. Specifically I have notes in a notebook app which I'm very keen to recover. I have no idea where these apps actually store information and whether or not it's embedded in some way.

I gather following the advice given may/will remove/replace all the apps along with the 'kernel'(aka Operating System??)?  Will this process lose the data?

Critically I don't know if the data I'm after is considered 'my/your data' in the context of the response given.

Thnx

Backing Up to SD Card Using TWRP and No Display
I have a device with a broken display. The only way I can initiate commands on it are with the power, volume, and home buttons, and with adb. I've installed TWRP on it, and I'm able to boot into it. I'm trying to back up everything on the device I can to a 32GB SD card in the device's SD card slot. But when I keep getting the following result:

```<code>~ # twrp backup SDBOM

Setting backup options:
System
Data
Boot
Compression is on
Digest Generation is off
Updating partition details...
...done
 * Total number of partitions to back up: 3
 * Total size of all data: 7976MB
 * Available space: 496MB
Not enough free space on storage.
Backup Failed
Done processing script file
</code>```

The SD Card has more than enough space for the backup (several times over, in fact), so clearly TWRP is attempting to save the backup to the device's internal storage. I've heard tell (I'm afraid I can't find the link right now) that twrp backup in the command line saves to the Storage last selected in the graphical version, but since my device's display is broken I can't select the SD Card as the storage for the backup.

Since I have no display, I also can't do adb backup --twrp, since that requires confirmation on the screen.

Is there any way to select the storage for twrp backup fully through the terminal? For example, is there an environment variable I can set, or something I can pass twrp backup?


问:
ADB restore: how do I restore the entire backup?
Before flashing a custom ROM to my Nexus 5, I made a backup of system, data and cache using adb backup --twrp; this gave me a 17GB backup.ab file.

My custom ROM endeavour went wrong and now I want to restore the backup. When I try adb restore backup.ab, it seems to only restore the system partition and not data or cache. Output on the TWRP screen:

```
Updating partition details...
...done
Full SELinux support is present.
Wiping System
Formatting System using make_ext4fs...
Restoring System...
[System done (190 seconds)]
Restore Complete
```

It completed way too fast to have transferred all 17GB back. How do I get it to restore the entire backup?

Phone: Nexus 5 32GB, TWRP version: 3.2.1-1


问:
How to allow read-only access to specific Android apps?
I would like to manually disable writing access only, yet still allow reading to a selected application onto the internal storage or external SD card.

Android so far just allows allowing both or none via settings.

How do I allow just reading for a specific application?


问:
Which process is locking the camera?
There is a problem with my UleFone Armor 2 with Android 7.0 Nougat:

After using the camera some times, it stops working due to the inability to connect to the camera.

I tried killing the camera application, but it does not yet unlock the camera. And the battery manager suggests that the camera was permanently on since the time it has stopped working.

A simple reboot does solve that problem, but rebooting is a seriois violation of an important Linux philosophy, which states that rebooting is never a good method of solving problems and should be avoided wherever possible.
