问:
Fastboot mode in my violet is blacked out
The thing is when I get my phone into fastboot mode, the interface is like nothing; it's totally blacked out.

I thought of connecting it with my PC and it is detecting the phone successfully. But when I wrote the commands to detect the fastboot, it isn't showing up.

I'm very frustrated that I can't change my custom recovery. My custom recovery is showing some errors so I also can't change my ROM.

How to fix this issue?


问:
Recover data from a phone that says decryption unsuccessful
I have a OnePlus device which is setup with face unlock, fingerprint and pattern unlock. Non rooted, stock Oxygen 10 and stock recovery. Locked bootloader.

My phone recently froze while unlocking and after a reboot it now says decryption unsuccessful. I seek some help in figuring out what my options are from here on. What must I do, so that I do not loose my data?

Will it be possible to perform a device dump from fastboot/adb and flash it to a similar device with similar pattern lock and get my files back?

Is there a way to backup the /data (apps, books, pictures, music) from fastboot/adb and have them decrypted in some other way? Or pull /data from adb/fastboot, reset phone and reflash the /data and hope for decryption?

Can I reset my phone without losing data?

Or should I reflash the stock OS?

Any pointers will be appreciated! Thank you!

Plug Android smartpone into PC without loading | LineageOS
I am using my main smartphone for developing Android apps and doing research.
I set everything up and searched for a specific option under USB Preferences, when connected to my computer.

As I don't want to drain the capacity of my smartphone, I'd kinda like an option like Data transer, but do not load, so that the battery can have normal battery cycles instead of always staying at 100% because it's connected to my computer.

However, I didn't find anything in the preferences or on the internet.

Does anyone know if there is an option for enabling adb to still function but disable charging while connected to the computer?

Btw, I am using LineageOS 17.1.

How to make a bootable ISO from Android CLI? (via Termux or Proot-distro)
I know there are some .APK apps that do it, but none seems to work for me (but if you have any suggestions, I'll try).

I have LineageOS on my PC. So, my question is How to make a bootable stick with in Termux?

Which commande should I install?

I have also installed some proot-distros installed (I'm currently testing them as a newbie), so, could I use one of them? Should I try to use Multisystem?

I had good success with Multisystem, so if I could use it either as their bootable ISO or their .deb with success, if you think it's possible, I'll listen to your suggestions.

EDIT: As asked, I add some precisions about my goal.
I'm trying to install a Multisystem ISO (or as a .deb package)
Installation inside a distro, as a .deb package: http://liveusb.info/dotclear/index.php?pages/install
Multisystem as an ISO here: https://sourceforge.net/projects/multisystem/files/iso/

I need to resize my /system partition, and If I can, create a /recovery partition, so I need to use Gparted ISO. And on the same USB, I need Also a recovery if my AndroidX86 fails to start.
So I decided to install Multisystem to make a multi-ISO stick.


问:
Permanent ADB RSA-key authorization
My phone screen is broken but I managed to finally tap the allow button for ADB authorization so I can access the device via ADB.

My question:

Is there a way to do this once and never be asked again or backup the RSA which I can then push to the device via ADB if it happens to need re-authorization again (since I have a broken screen I just can't tap allow again).

I have enabled do not ask again on this device, but that does not seem to work from past experience and it keeps asking me to authorize if I reboot the phone.

Permanently set app on launch (kiosk?)
I rooted my old Galaxy J2 today, and replaced the stock firmware with LineageOS. It works great.

My next question would be to set Retroarch the first and only app on startup, which supposedly is kiosk mode, so as if the phone would basically run Retroarch as its own system. I researched a lot about this (it is called kiosk) but no clue on how to do this.

Can you help me recover my accidentally deleted videos?
I have a Nokia 2.2 smartphone runnig Android 10 ( a hateful piece of software from my opinion). From 16 GB of storage only 2 are available for the user and it's shrinking even more with every new update. That's why I have disabled auto update and installed a sd-card in storage expansion mode (the phone uses the sd card as the internal memory).

I've been gone on a trip and took some videos and photos with the phone since I ran out of memory on my compact camera. On the way home, out of pure dumbness I deleted the DCIM folder.

"Fine, I will just install a recovery app." Guess what? Those require root and the Android 10 system is not vulnerable to any root exploits that I know. And Nokia will not allow me to unlock my bootloader!

"Ok. I will take the card out, plug it on my computer and start recuva from piriform." It didn't work. Windows is unable to open the card, but it shows it on device manager as 2 "healthy" partitions. "Maybe it is an ext4 file system and it will mount just fine on my linux laptop (Q4S Trinity desktop based on debian)" That one doesn't even detect that I've connected the card! The only device that is able to read the card is my phone! What can I do? Is there any way that I can  get my videos back? A firmware dump? How can I do that? Thanks in advance.

Not what I asked, and this happens frequently.

Is this a preference, is there any way to turn this off?

问:
Camera doesn't save with new SD card and how to decrypt files from old SD card
it seems I had a bad idea yesterday. I got a new SD card for my Fairphone 3+ (running Fairphone OS/Android 10). There was already an SD card inserted I assumed not to be in use. So I turned off the phone, exchanged the cards, booted the device and when asked to extend the phones memory I confirmed that.

Now I have two problems:

I'm missing a couple of pictures.

I wondered if these were on the old (luckily only 8GB) SD card and recognized that there are two partitions on it: android_meta and android_expand. As far as I learned, this means the SD card also was used as phone memory extension and thus encrypted. And the posts on Android Enthusiasts read like the phone has only one encryption key and won't recognize the old SD card anymore.

The Camera can't save pictures anymore.

Whenever I take a photo I'm able to immediately open it by tapping its preview. Then I see a black picture, I'm told its size is 0 bytes and it's located in /storage/emulated/0/DCIM/Camera. Using the cx File Explorer I'm able to open that directory, but it's empty. And I'm not able to create files there.

Using the ADB shell I was able to ls -la /storage the directory and got this:

```<code>total 7
drwxr-xr-x  4 root root        80 2020-12-21 06:52 .
drwxr-xr-x 21 root root      4096 2009-01-01 01:00 ..
drwx--x--x  4 root sdcard_rw 3488 2021-01-12 21:38 emulated
drwxr-xr-x  2 root root        60 1970-01-01 01:00 self
</code>```

So only root is able to write in /storage/emulated. BTW: "total 7"?

Currently I'm trying to find out the following:

is it possible to decrypt the pictures on the old SD card? Would be fine for me if it meant some work :)

is the encryption key for the old SD card still on the phone or could I reset the phone without making things worse regarding the old encrypted SD card?

is the phone in a bad state?

The Camera doesn't save pictures.

All other apps seem to work as expected.

The SD card overview in the Memory settings tell me there are apps on the new SD card (about 5GB). But when I tap the App category to get all apps listed, the list is empty.

When I eject the SD card, a couple of apps start, but only show a blank canvas.

if the phone is in a bad state: could this easily be fixed? If yes, how?

Would be great to get some hints. Thank you very much in advance.

Pixel 5 bootloop after flashing patched magisk boot image
I was running Magisk on Android 11 on my Google Pixel 5.
I installed it using a patched boot image from 11.0.0 (RD1A.200810.021.A1, Oct 2020, EU carriers).
Today Android 11 prompted me with an update, I installed it without thinking about the consequences. After rebooting Magisk stopped functioning. So I rebooted to fastboot mode and flashed the same patched boot image as i did the first time. I flashed both boot_a and boot_b, I remembered i did that the last time.

After that the phone is stuck in a boot loop.

I also tried flashing the unpatched boot image from the original image, but same effect.
Maybe i had to patch the latest magisk version on a fresh boot image, but can't do that anymore without access to magisk on my phone. Was running the latest canary YAHFA version.

Don't know what to do anymore, really hoping there is a solution without loosing all my data.

In the end i fixed it with extracting the boot image from the correct factory  image. At first I didn't see that the latest image was at the end of the list here https://developers.google.com/android/images
Flashing the boot image gave me a 'no command' screen. But I was able to boot into safe mode. After that i could patch the boot image file with magisk, and patch it in fastboot. And then everything was working again!

Android patttern lock reset
Awesome people! I need help!

My wife's old Xperia z1 has a broken digitizer, the phone is pattern locked without showing the path. Of course, no one can remember the pattern, USB debugging is not enabled, no root and no google account shows that it is paired with this device. I care about photos so is there any way to take a memory dump to an SD card or to clone the phone content without debugging mode?

Or any other way to bypass pattern lock without debugging and root?

问:
How can I programmatically filter incoming traffic on an Android device via an app?
I need some pretty thorough guidance on a project I've been tasked with. I guess ideally I am looking for either a tutorial (or set of tutorials), or else a working, self-contained, open-source codebase for an Android app that can filter all incoming internet traffic on the Android device based on keywords.

In particular, the app will stop incoming HTTPS traffic for any given web request if the requested URL or webpage (not just the domain) has certain keywords in the HTML or the URL. If a request does not have the keywords, it will be allowed through and the device will function normally. If it is not an HTML or TXT request -- if there is no text to analyze except the URL -- then it will look for keywords in the full URL alone.

By self-contained, what I mean is that it should not require a remote proxy server or remote VPN.

I have searched Google for such a thing. I've searched in GitHub.

I've seen plenty of tutorials for setting up a local proxy or VPN... all point-and-click kinds of tutorials. I need something programmatic.

I've found libraries that supposedly allow you to set up a proxy from inside an Android app, but their documentation is too cryptic and there are no step-by-step examples for them, so I can never make them work.

I've found a few open-source apps that do some of this, but aren't quite what I'm looking for. Nothing that really does what I need it to. I've tried to alter the apps that I've found to turn them into what I want, but my knowledge is so limited and the missing pieces are always too numerous.

I've been working on this for months. Sad, I know.

Can anyone point me to a fairly thorough tutorial (or a set of tutorials) that will help me to build such an app? Or, can anyone point me to an existing open-source app like what I'm looking for? Or even something that comes pretty close?

FWIW, giving me broad advice like "you need to set up a local VPN and a local proxy, with a certificate, and then use the proxy to filter traffic" won't be of any help to me. I already know the broad outline of what I should probably do. I just can't figure out how to do it, and can't find any good resources for guidance! Which is why I'm here...

Thanks in advance!

This is a Xiaomi Redmi 8A running Android 9.  It is not rooted. As far as "how /when did it happen" I do not know more than this: somehow it ended up that ALL  applications were selectable with a white round circle and asking "DELETE apps" or something similar.  I had never seen that mode before (or since). I tried to get out of that mode but ended up with accepting the Camera that was selected and got deleted.

Draw unlock pattern without having to swipe first
When an Android 10 phone is locked, it shows notifications and says "Swipe to unlock", then after swiping it hides the notifications, and shows the pattern lock saying "Draw unlock pattern". So the unlocking requires two steps (swiping and then drawing).

Andriod 4 directly shows notifications and the pattern lock below them. The screen is smaller than on the Android 10 phone, but it still all fits on the screen. How can this be achieved on Android 10, without the unnecessary first swiping step?

This is not about Android 3 like here nor Android 6 like here.
This is not about changing the timer for the swipe like here, but about removing the swipe completely.

How to reinstall of Android on a tablet?
I am learning Android app development. I wanted a cheap tablet to test how apps looked on tablet as opposed to mobile. I bought a cheap tablet from wish.com.

OK, stop laughing at that last bit... it seemed like a good idea at the time.

What I received (and was subsequently refunded for), was a tablet that seems to be locked to only the Chinese app store that was already installed. I can't install Google Play (I have tried multiple versions), and therefore it is pretty useless to me.

I did manage to install a version of Droid Info which pulled up various data, build number, kernel, Android version etc.

Is there any way I can use that data to find, and flash the device with a clean version of Android that might work?

This thing is good for nothing but the bin, otherwise.

Appreciate any suggestions.

Any way to preserve portable hotspot configuration (SSID, key)?
How can I preserve my initial portable hotspot configuration (mainly current SSID, encryption) settings on my device.

I couldn't find any thing useful because it looks so much like the prebuilt kernel extracted from stock firmware, there is no kernel panic and I found and the timestamp in the second line does not seem to be right.
My wild guess is that I am not debugging it in the right way, the actual log for my compiled kernel is flushed when it boots to recovery or the system.

So is there any advice for me the to debug the kernel without booting to other environment?
I really apperciate your help.

Does sync work on Firefox Lite for Android
As a privacy conscious user I am trying to decouple as much as possible from our internet overlords Google, Facebook, Twitter et al. To that end I have decided to shift from using Google Chrome to Firefox as my primary web browser both on my computer as well as my Android mobile device.

The main Firefox app for Android is quite big, and there is a smaller substitute for called Firefox lite. My preference is to use Firefox lite but it is essential for me to be able to sync my bookmarks and saved logins across my computer and mobile device. While the main Firefox app allows me to sync, I haven't been able to figure out how to sync over the Firefox lite app. Has the sync feature been excluded for this "lite" version of Firefox?

Some websites not reachable using cellular data but working perfectly using Wifi
I a have a Xiaomi mi 9 se phone and I am not able to access some websites using their IP adress. To give you some context, I have some servers I wish I can access but it not possible, I receive a ERR_ADDRESS_UNREACHABLE in chrome for android when using cellular data but the same IP address works fine using Wifi. Using another phone (Google pixel) the same address can be accessed without any problems using cellular data.

I though it could be a carrier issue but I tried the sim card from the Google Pixel putting it in my Xiaomi phone and still it does not work.

I tried tweaking with DNS configuration but still nothing.

Connecting to a private IP over WiFi and public IP over LTE simultaneously
I'm designing an Ubuntu app for Android which is running through a Termux chroot jail. The app requires the phone to be connected to a drone through the drone's generated Wifi network. This network does not provide internet access (obviously). Unfortunately, I still need the app to have general internet access while connected to the drone network. This means I need to be able to designate certain address accesses to use LTE and others to use Wifi. Any idea how to set this up from within the chroot jail (or externally)?

How to host a public website with my domain name on Android?
I have my own domain name, richardbrowning.cf, and I want to host my own website (using this domain name) on my Android phone. My Android isn't connected to Wi-Fi (I am using Mobile Data).

I started locally hosting my website on my Android, (and it was available at http://mylocalipaddress:myport. Then I went to my registrar and added an A DNS Record setting the target to my local IP Address. Now if I go to richardbrowning.cf:myport, I can view my website. But it is still only local.

So I have two issues. I want to make my website public, not just local (so everyone can view my website) and I want to remove the need for putting :port at the end of the domain/website.

By the way, an end note is that I tried putting my external IP Address into my DNS Record instead of my local IP Address, but this doesn't work because there is nothing being hosted to this external IP Address. So if I could maybe host my website to my external IP Address and then put this external IP Address into my DNS Record, then that would work. But I can't find a way to host my website to my external IP Address. I only see ways to host my website to my local IP Address (locally). Thanks in advance.


问:
Is my old phone still recoverable after super bricking it?
A long time ago, when I was way dumber, I really wanted to upgrade my old phone (Wiko Lenny 3) from Android 6.0 to Android 7.0 but with no avail. Since that day, the phone is no longer bootable. If I try to connect my phone with the computer, it won't even detect it. I tried every way to fix the full issue.

What I mean with "super bricked phone" is that I tried to install another phone's system (Wiko Lenny 4 probably, can't remember) into the main phone, which lead to the complete brick that the kernel, system, boot, preloader and such stuff are corrupted. Now I know that I can buy another motherboard and install it into Wiko Lenny 3, but I don't want to waste that much of my money for something that I completely rigged.

If there is any other way to fix this issue, then I could try without making more damage to the Wiko Lenny 3 phone.

Edit 1:

I tried to find the KCOLO/KOLO/COLO point, that I need to short with the GND golden point, but I literally can't find the KOLO point. This device has 2 GND points, so with this, I don't know which I need to short. I provide an image to it

What can be done with a phone that has an encrypted bootloader
I am trying to get a rooted android phone set up for reverse engineering purposes. I tried to root two separate phones (SM-G925A and a Google Pixel 2) but they both turned out to have locked (meaning, encrypted by the carrier) bootloaders.

Is there really no way to get around this without finding an exploit? I have tried everything short of taking the phone apart and flashing the ROM in (whatever device you use to flash a ROM chip.) Would that even work? I can't even find a single example of someone doing this for any model of phone on the internet.

问:
Obtain log of when audio starts and stops
In Android 11, at least in the version Google uses for their phones, all audio apps can be controlled with media buttons you see if you pull down the notifications/top/task/whatever bar.

My question is: How can I get a log of when I stop and start audio from the top bar media buttons?

The log needs to include timestamps, so I can see how long something has played for. It would preferably also include some information about what was being played, such as the title of the track or podcast. It also need to always go at least one week back in time, which seemingly rules out using logcat the standard way.

Any way of doing it would be okay. For example:

An app that can monitor audio plackback on the phone.

Getting system logs through ADB.

"System traces"?

As far as I can tell, Android destroys logs from before that last reboot, but I might be wrong about this. The log I get by running adb logcat gives me the information I need. It seems I am only able to get logs since the last reboot though. If I can access old logs, that would be a solution to the problem and you would get the bounty for helping me achieve this.

If there is a way to know when I start and stop playing audio from within an app, I would also accept an answer that lets me get this information. I don't mind if the information comes from the media buttons or not, I just want to know when audio starts and stops playing on the device.

Android Recovery is loaded instead of TWRP after flashing TWRP with Odin
There was this question here the solution to which was to boot into TWRP before booting android, so that TWRP isn't replaced by Android Recovery. I can press UP+Home+Power and go into recovery - I've not had an issue with that. But the trouble is that rather than showing TWRP it shows an android logo and it says it "updates the system" and then what comes up is Android Recovery instead of TWRP.

I'm using samsung's SM-g532g (galaxy j2 prime). It does not have an official TWRP apparently, so I'm trying the TWRP that this site suggested. I've tried it many ways: I've booted into recovery right after flashing TWRP, removed and replugged the battery and then booted into recovery, etc.

enabled oem unlock and usb debugging

connected to computer

logged into adb and send adb reboot bootloader

send fastboot erase recovery

flashed this    file using fastboot flash recovery <filename.img>

tried to boot    directly from the image using fastboot boot <filename.img>(after a    while without any respond it performed a
normal boot to system not to    recovery)

then I tried to reboot to recovery by these methods

pressing and holding Volume Up and power button until the Infinix
boot logo appears(after releasing all the button it shut down without
showing anything,booted again and performed a normal boot)

send adb reboot recovery(it boots to system recovery not to twrp)

What is the problem? Is this image corrupt or not right? If it is can you provide any image for X5515F(not for X5515).

However as mentioned in the title, the two phones are unable to install 64bit apps from the Google Play Store. I am suspecting that the reason for this is because their OSs might be 32bit. (I can't check personally because someone else has the phones and I am trying to solve a problem for them.) If that is the case, is it wise to flash a 64bit OS to the phones to be able to run 64bit apps?
Below are the links to the chipset specs on their respective websites:

Could Static Electricity interfere with HP Pavilion Active Pen?
My HP Active Pen worked for two months with my new HP Pavilion x360.  They are sold together.  Then it stopped.  I changed batteries and it worked again, for a day or two.  Then it stopped.  Changed batteries again, but it would not work.  Put it aside a few days, now it works again.  I am wondering if placing it on the end table by the couch with my cell phone, my cell phone QI charger, or possible drips from drinking glasses could have short-circuited it.  Also, there is a lot of static in the house this year,  Every time I pet the cat, he backs up from the static.  Could that interfere with how the pen works?  This pen does not use bluetooth, only a single AAAA battery.

Can anyone explain this to me?

Is it possible to find out what apps created a given file/folder?
I want to keep track of the application that created the folder.

I use an Android phone.
And some apps automatically creates unnecessary folders in the root directory of my phone.
I want to know where they come from.(The photo below is an example.)

I can delete that folder but it will be recreated within few minutes.
Are there any apps or adb commands that can monitor whether a folder or file is being edited?
Or, is there a way to block the creation of a folder with the same name?

I have read all of the guides but may still be wrong. Please tell me if this is a duplicate question. I apologize if this is a bad question.

I want to catch the culprit!

My storage keeps increasing drastically despite not downloading anything and freeing up lots of space (4GB>200mb??)
I am using a Huawei P10 Lite.

This is absolutely insane and I desperately need a solution, I can't even begin to imagine what's causing this.

I've been getting the whole "storage space running out" message for a while now, so yesterday I went ahead and I ported 4GB worth of space to my SD card, leaving tons of free local space on my phone. The message dissappeared after this.

And yet today I suddenly get the same "storage space running out" message, I go look up the amount of storage I have in settings, and suddenly it says there's only 400mb left, and a few hours later now there's only 200mb left. How is this possible?? I freed up 4GB and now suddenly there's only 200mb left?? Something's very wrong here.

I DID NOT DOWNLOAD A SINGLE THING IN THIS TIME PERIOD, NOT ONE THING

Some things worth mentioning:
-I have auto-updates off, so that's not the issue here
-When I check my local folders it all amounts to about 5GB, not even close to 32GB which is the total internal storage of my phone
-I already uninstalled updates of built-in apps I don't use, it didn't change this problem
-I use Clean Master to delete cache and free up space, but it keeps increasing more and more regardless
-Due to certain circumstances I cannot do a factory reset right now and need a different solution

If there is any other information you need please don't hesitate to ask

This is a massive problem for me and I am desperate for any solution or just fidning the culprit behind this for that matter... thank you all very much for your attention.

How to eliminate all not chat-related from the Facebook Messenger?
I do not want to see anything from the facebook what is not chat-related, like:

the integrated facebook browser (yes, it is not a joke)

popups of my pals currently logged in

excerpts of their facebook posts

many-level influence of my phone GUI (like flooding of my sharing possibilities by my messenger contacts)

My goal is to entirely eliminate facebook from my life, except the messenger chat and video calls, because I can talk with some people only there.

The best would be an opensource app which knows the facebook messenger protocol, and serves exactly this purpose. Alternatively, not opensource apps, or the tunings/settings of the currently available apps would also do.

System storage taking up loads of space after adopting SD card
I recently adopted an SD card to my Xiaomi Redmi 7. Before I adopted the 64GB card, I was using around 8GB. Now my file manager says I am only using 2%, and under internal storage in settings I have 60GB of internal storage free. But under storage in settings, it says system storage is using 55GB and I only have 500MB free. I'm also getting the old notifications saying my storage is running out.

I'm not sure I understand the difference between internal and system storage, but I definitely can't see how system storage is using 55GB when it previously was happy with 7.

If anyone can help I would be most grateful.


问:
SM-T350 Micro-USB port charging but not transmitting files
My belief is that my SM-T350 (Samsung Galaxy A 8.0 from 2015) has a corrupted port which can only charge, not transfer files. Is that possible? Has anyone found any fixes short of taking the device apart and replacing the micro-usb port? Have I done anything wrong on the software side (see info below)?

Info:

I recently bought the SM-T350 off ebay as a cheap tablet to install ROMS, root, and generally do things on that I can't do with my daily driver phone. When I went to flash TWRP from my computer (Ubuntu 20.10), I found that the device was not recognized by adb. Specifically, running:

```<code>adb devices
</code>```

returns the output:

```<code>List of devices attached

</code>```

implying that no devices are attached, even though the SM-T350 is in the MTP mode in developer settings and USB debugging is enabled.

Seeing this, I figured that I'd run into the age-old problem of a cable which only charges and doesn't transfer data. It had been the cable from the box, so I tried connecting with a different cable (which I know to work both transferring data and charging). adb devices still didn't recognize it, so I know something is either wrong with my computer or the tablet at this point.

To eliminate variables, I borrowed my nephew's tablet (coincidentally, a Samsung Galaxy A 8.0 from 2019) and hooked it up (with the working cable, to the same computer) to see if adb devices registered anything. Sure enough, it outputted:

```<code>List of devices attached
R9WMA0N3LCJ device
</code>```

My nephew's tablet (the 2019 one) also was recognized by Ubuntu as a removeable filesystem, whereas no such thing happened for my SM-T350. This is why I believe that the problem lies in the port's file transfer capability.

How to actually delete SMS/MMS messages using third-party SMS applications like Pulse SMS?
A while back, I switched from Samsung's default SMS app (Samsung Messages) to Pulse SMS.

For many months, I've been using Pulse SMS to delete old SMS and MMS messages.  After deleting almost all MMS messages and thousands of SMS messages, I backed up Android's SMS/MMS database using Epistolaire.  Much to my surprise, the backup was over 500GB.

Given that SMS messages are tiny, I immediately knew something was wrong.  So I loaded up Samsung's default SMS app, and sure enough, every one of my supposedly-deleted SMS and MMS messages are still technically on the Android device (even though thousands of them had supposedly been deleted by the Pulse SMS app).

Besides going through tens of thousands of SMS and MMS messages again, how can I remove all the supposedly-deleted SMS/MMS messages from Android without removing the thousands of messages I want to keep?

Also, how do I prevent this mess from happening in the future?

Viewing files on Android phone from computer, only showing DCIM and Pictures folders, in internal shared storage
I have phones running Android..

When I connect either one to my computer, and click "internal shared storage", I only see DCIM and Pictures..

But if I go to any decent file manager app on the phone then it shows far more folders within "internal shared storage" e.g. Download, and other folders.

One of my phones, comes with what looks like a nice app for backing up, and it creates a folder with the backup, and I want to copy that folder to my computer. But I cant see how to access that folder to copy it onto my computer!

I'd be a little bit surprised if this is a situation where the phone has to be rooted to do it.. I do plan to, but this is an app that the phone comes with. So some may backup the phone before unlocking the bootloader.


问:
How to hide your SSID from apps / keep your Android apps from finding your Wifi SSID?
As far as I know, all android apps are able to scan nearby / available Wifi networks. They can either get a list of nearby SSIDs, or at least they can get the SSID of the Wifi you are currently on. Correct? I remember the "get wifi scan results" unrevokable permission from some time ago (stoppable only if you were rooted and had xposed framework) (Also, exhibit B: Google, SkyHook, and Apple SSID databases).

This means that even if you are on a VPN, even if you turn off wifi scanning, even if you turn off location services and take out your sim card, even if you stop broadcasting your router's wifi SSID, your apps will be able to know what wifi SSID you are currently on.

This means that an attacker (read: the surveillance capitalism :) ), can figure out if/when I am home, and which other devices that are/were online have used the same SSID. E.g. all my family's (mandatory) banking apps will know where my family members congregate, and could change my insurance score, or other "insert dystopian scenario here".

Considering what I described, I don't think there is any wiggle room for you to ever hide your real location from a bad (state, corp, hacker) actor. Am I wrong? Can I hide my SSID from the apps that are on my phone?

I can't believe there aren't any hits on this subject on the internet.

(PS: obviously, the point of the question is not whether or not I am paranoid, the question is whether this is technically solvable)

[EDIT] To be clear, I haven't technically analyzed recent Android versions, but my question is about the most recent Android versions, as those are the versions everyone's obviously moving forward with. E.g. Android 10, Android 11.

[EDIT2] Would also be interested if iOS offers better privacy / protection in this regard. I created a sister question on "Ask Different", and spoiler alert: APPLE DOES NOT HAVE THIS PROBLEM. (as much as I hate apple's UX and lack of customizability and user control, at least rogue apps don't get that control either)

Sharing image makes phone very unstable
I think that Motorola One can be considered a quite powerful phone with its octa-core 2.0 GHz Snapdragon 625 and 3 GB or RAM. It also produces a fairly small images of 4160x3120 pixels and approx. 3-5 MB in size. Based on that specs, I'd say that sharing image should be an instant experience.

Yet, in fact, it is a nightmare in my case:

attaching single image to Gmail (to share it via email) takes 20-30 seconds, sometimes more and often hangs Gmail itself for a moment (i.e. I can write an address or message content during adding of image) or permanently,

attaching image to Messages app (to share it via MMS message) takes 30-50 seconds or even more, often hangs Messages app and on a few rare occasions hanged entire phone.

Is there anything I can do about this except for uninstalling Gmail and Google Messages and start using another email and messages app?

BTW: We could say that my slow network (which is not slow) can be considered as a contributing factor in case of Gmail. But could it also explain MMS experience? Which has nearly nothing to do about data transfer over Internet during MMS message creation?

Merge overlapping WhatsApp backups
I flashed my phone last year, but before that, I made a WhatsApp backup. However, the WhatsApp backup made wasn't complete(perhaps I exited the app while backing up). Hence, I lost 1 year worth of chat history.
I have an old phone which still retains the chat history, but the chat histories are overlapping, as described below:

Old phone chats: 2015(month unknown) - June 2018

New phone chats: 2016(month unknown) - present

I would like to merge the chat histories (and preferably, call logs too) to contain the chats from 2015 - present. I have seen many WhatsApp backup merging tutorial and posts like in here, but these only explain how to merge the backups if the chat histories do not have overlapping chat histories. How do I merge two overlapping chat histories, without causing messages from 2016-2018 to appear twice?

I only need to know how to merge the wa.db and  msgstore.db and other relevant files, if I need help in retrieving them and altering them I would post it as another question.

问:
Problem with camera concerning file names und photos app

Short version:

How can the camera app be brought to save pictures again with the regular format "IMG_2021....jpg"? On my Nokia 7.2 this is not the case anymore (see picture).

Long version / additional explanations:

Before I bought my Nokia 7.2, I used the SD card already in a Samsung Galaxy Note und hatte and had stored on it (among other) several pictures. For the new pictures, a new folder was automatically created and the old pictures remained saved.

Sometime, an additional folder was automatically created without that I had anything to do with it, maybe due to an update. After that there were three subfolders in DCIM, both on the device and on the SD card:

100ANDRO (probably from Galaxy Note, but I'm not sure anymore)

Kamera

Camera
From then on, the pictures got stored in the folder "Camera". Until that point, everything was allright.

At the end of last year I noticed that new pictures don't get stored anymore with the regular format "IMG_2020....jpg" but instead with an unlogical file name, see screenshot of Windows file explorer. Only newly created videos still get stored with with the regular format.

A few days ahaid of that, the following had happend:
The "Fotos" app from Google suddenly claimed that there was no access to delete pictures (which had always worked before) and that I should use the gallery app for that. Therefore I installed Google Gallery and for comparison one or two additional gallery apps. I then could delete pictures directly again and didn't have to switch to the "Files" app or another one.

When I realised the new file naming of the pictures I first thought, it might have something to do with the installation of the gallery apps and I removed them again. However, that had no effect.

My next attempt has probably caused a subsequent problem, but didn't solve the original issue: In the system settings I deleted the cache and data of the apps "Kamera" (Google Camera) and "Fotos" (Google Photos). Since then, new pictures are still stored with the 'wrong' file name.
On the other hand, I noticed - just a few days later - that many old pictures are missing. The folders "100ANDRO" are both empty, both on the device and the SD card. At least the folder on the SD card had contained several pictures before. The two "Kamera" folders have vanished with the containing pictures. From all the created pictures I don't have anymore those from about 1 1/2 years.

I find it disturbing that pictures made with the camera are removed when deleting the data of any app. From my point of view, the folder DCIM does not belong to any app at all, as opposed to f. ex. the folder WhatsAppImages in WhatsApp > Media. Anyhow, I probably have to live with that; a restore of the deleted pictures is rather time consuming and/or expensive.

But how can the Google Camera app be brought to store the pictures again with the regular format "IMG_2021....jpg"?

Thanks for your help or any tipps.

By the way, why does the Camera app frequently change the storage folder from sd card to device? (If I'm not mistaken, this didn't only happen after installing updates.)

Gogle finance desktop shortcut stuck in weird state
Siituation

I got into very strange state after sync of my old phone (Pixel 2) to my new one (Pixel 5). The phone (or chrome) thinks that the Gogle Finance shortcut for the widget is on the desktop but it is not. What I want is the shortcut not for the webpage that opens in chrome but the one for the widget app (not sure if it iis PWA or just part of the Google app on clean Android phones).

The problem and what I tired so far

When I open Chrome and go to google finance website, I don't get the option to add shortcut on the desktop. I can go around that by using incognito window or Google Go app. But in both cases when I press add shortcut, it doesn't do anything. I also tried deleting all permissions and data of the google finance webpage but it didn't help. Uninstalling Chrome updates and installing it again didn't do anything as well as deleting all Chrome saved data.

Update

I tried to log in with different account in Chrome, that displayed the popup to add the shortcut. When I press add the shortcut, it will try to open the google finance in the default Google application and fail. The page just doesn't load. I guess it's a problem with Google app then.

The Google app has one great disadvantage which hasn't been addressed since it was created. It's not a standard app. That makes it ridiculously difficult to control when using the phone. Switching between apps very often makes the app disappear and you always lose any state of the app you had. So it is very hard for example to read news, which is one of the core functionalities (considering Google actually made it as a separate desktop when you swipe left on your home screen).

Update 2

Basically this whole section is useless if you open it in Chrome and makes you see much less of the screen. Not to mention that icon on your desktop for Chrome link looks much worse than the one for the "native" app.

Worried about possible malware
I'm hoping someone can help me here. Yesterday I was doing some research for an essay when I clicked a website (very dumb of me, who never clicks suspicious websites or links) that redirected me. I immediately backed off, the page didn't load. If anything I spent about a second there. Being the paranoid person I am, I have malware bytes installed, scanned, clear. Avast, clear. Sophos warned me about a PUA, which was a .com.google.chrome(some letters) file. Immediately deleted it, but then again Sophos also warned me about another app being a PUA, when it's in fact, safe.

I cleared the google chrome cache. I'd like to note that I DID NOT download anything, I didn't click any links, I didn't click anything but the back button, I didn't give any permissions. I'm on android 10, Xiaomi redmi note 7 (encrypted), and updated to miui12 last night. My phone isn't acting odd or anything.

I'm just extremely worried about being infected. I checked that website on hybrid analysis which came back as malicious (attack method as hooking), virus total said the same, but google safe browsing didn't detect anything, this site was detected as malicious on 2-3 checkers. I was on google chrome at the time.
Should I be concerned?

I don't do banking on my phone as I have a separate apple device for that.

Is there anything else I can do, for peace of mind? Thanks in advance.

How can I restore the browser button?
For some magical reason, the browser button on the home screen of my Android phone (Xiaomi MI 9 SE, MIUI 10.2) has gone missing. I can't find it!

... how can I restore/recreate it?

Note I'm not talking about a specific browser (FF, Chromium etc) but the generic browser button.

Is it possible to change the geolocation settings or completely disable geolocation for smartphone with developer mode?
Can I change the geolocation settings with developer mode? For example make the main positioning mode with using only WI fi network  instead of using  GPS +GSM +WI fi?

Or it can be done only with root?


问:
If we want to give the apps fake geolocation datas is it enough to change only the GPS data or i need to change all datas that are transsmitted?
When we change the GPS data using fake GPS app the cell id of our BTS still shows completely different region (the region of our real location). Isn't that enough for third-party applications to understand  that the received Gps datas are fake ? We know that most of positioning systems using hybrid thechnologies for positioning and not a specefic one .In this case if we want to give the third party apps  fake datas  is it enough to change only the GPS data or i need to change all datas that are transsmitted (Gsm,wi fi, ect.)</p>

How to run hostapd on Redmi 8
I have been trying to run the hostapd with my own hostapd.conf but it's refusing to work and keeps saying segmentation fault and I am wondering how to get it working on Redmi 8 running Android 10

How to find where an app is saving its data and then acess it?
This app provides offline acess to a big database. So it must be somewhere in the device. But i'm having trouble finding where, and if I could even access it when I found it. I can't find the folder data/data suggested here Where Android apps store data? . So I'm guessing that I'll not be able to access it without root ?


问:
Using NetGuard, what app(s)/service(s) can be restricted to prevent system updates?
I've been using NetGuard for a little while now, and I've really liked it so far. I hate the forced system updates which seem to come more and more frequently. For a handful of reasons, I'd like to prevent this from happening via NetGuard, if possible. I have to imagine there's a service or two which compares my Android version with the latest available version, and perhaps another which actually downloads the latest version. The problem is that the list of apps and services to restrict are vast, and I have no idea what most of them do. What on this list needs to be restricted in order to prevent all future forced updates?</p>

"can't login on a rooted device" and banking apps not working on rooted devices with MagiskHide+SafetyNet on

Samsung S9 Plus

Lineage OS 17.1 with /data encrypted

GApps pico

Magisk + Magisk Manager + MagiskHide with SafetyNet on => basicintegrity=OK + ctsProfile=OK + evalType=OK (blueish screen)

Several apps that are (mostly) related to finance (Revolut, XE, etc.) are refusing to start because my device is rooted.

Several forums that I've read through advise to do the above, i.e., Magisk + SafetyNet, which I have done. However, nothing of that works. I've even tried to "hide" /sbin/su by renaming it for a moment, but that didn't do the trick either.

I read something about GApps pico/picoG being the culprit, saying that micro/microG should be the bare minimum to effectively "hide" the "rooted" status, but I'm not sure about that, and reinstalling everything isn't something that I am particularly looking forward to, unless there is no other way.

I know that this is a cat-and-mouse game, but any other suggestions I should try?


问:
Is it possible to add a feature from app to another through .xml editing?
So I had just discovered this keyboard app called the Multiling O Keyboard which is very useful, but one thing I hate about it is that, it doesn't have the permanent notification feature which the Hacker's Keyboard has.

So is it possible to add the Hacker's Keyboard's permanent notification feature to Multiling O Keyboard?

This feature will help me open the soft keyboard even without textfield to write into like the Hacker's Keyboard.

PS. I'm not good in coding, I just want a decent keyboard for myself.


问:
Lower half of screen looks pixelated on Chrome for Android
I recently finished developing a website made of scalable vector graphics (SVG). The site looks great on all devices but Chrome for Android. On Android Chrome, the site looks more pixelated near the bottom of the screen. I have cut out a sliver of the site to demonstrate below.

Image resized; click the image for full size. Note: you will probably have to view the image in a bitmap editor to see the difference, as your browser will blur the pixels together in JPG format.

If I scroll the content up, the same section that was just pixelated becomes crisp. It has nothing to do with my graphics, it's all about where they are on the screen.

I am imagining that this is possibly:

A numerical-related bug in Chrome Android's anti-aliasing algorithm

An intentional feature that figures people look at the top half of their phone screen when reading articles and so increases resolution as they read, pixelating the bottom of the screen almost like a camera focuses on stuff

Or more likely, some combination of the two

Does anyone have any familiarity with this effect? This is not present in the Android built-in internet browser on the phone. What is the cause of this pixelation in Android Chrome?

问:
Where are the libraries/dependencies for an Android app stored on the file system?
I found a file path from Where Android apps store data?

/data/app/<pkg>*/lib/<arch>/*.so (shared libraries)

However, this only shows libraries for some apps.

Is there another location where shared libraries are stored for an app? If not, is there a way to find this information from the APK or such?

Note: I have root on my phone.

Half dead screen, trying to recover data (device not showing in file explorer)
I have a somewhat old Samsung S7 Edge phone which (strangely enough) has only the lower half of the screen not working. This is, the whole screen lights up and displays everything, but ONLY the lower half is unresponsive to touching. As such, I cannot unlock it and turn usb debugging on.

It is not rooted nor do I know how to do it; I don't really know a thing about coding.

I have seen many previous threads and web pages about this, but at most I am very confused and don't want to brick it.

It doesn't have any really important files, but very old GBA roms I would really like to keep, as well as some photos and pictures I may have. Any help appreciated!


问:
How can I restore Google Chrome after I deleted it on my rooted phone?
I have a rooted Mototrola G6 Play, and today I deleted google chrome because I don't use it, but once I deleted it a bunch of apps stopped working like LastPass and Coursera just to name a few...

I tried downloading it back from the play store but that didn't fix it.
I also tried making it a system application again using Lind2SD but it asks me to reboot and when I do it gets deleted.
I also tried manually installing the apk and placing it in /system/app/ and in /system/app/Chrome/ but that didn't work either!

How can I fix this problem?????

Edit: I was able to make chrome a system app again by changing the permission to rw-r-r after putting the apk in /system/app/Chrome but the apps are still broken!

Edit 2: I've just uninstalled and reinstalled the broken apps and they started working again!
