I'm trying to factory reset a Samsung Galaxy S20 because I've forgotten to add MDM in the initial setup, and as far as I know,w you can't add this later. To do the factory reset, I've done Settings > General Management > Reset > Factory data reset. Then tap Reset and Delete all. But it then asks me to confirm my Samsung Account, which it somehow can't do, because I always get a loading icon that fails after some time. Then it asks me for the password of my Samsung Account, and again goes into a loading icon, which also just stops after some time. I don't get any error message. There's also the option to send a confirmation e-mail, but this also leads to the loading screen, and after some time, I get a little pop-up telling me there is a network error. The screen here stays white, and I need to use the back button to go to the confirmation screen of my Samsung Account. I do have internet access on my phone, because I can open websites with Chrome. I'm using my home Wi-Fi network to connect to the internet. I didn't find any solution to this problem with Google, just the normal documentation from Samsung on how to factory reset a phone, which doesn't work for me.

I'm in the process of switching from a Galaxy S20 to a Pixel 7 Pro. Both are running Android 13. I completed the data transfer, but my old wallpaper (a picture I took a long time ago which I really like) didn't transfer. I cannot find it in the wallpaper and style control on either phone, and I've tried looking everywhere in the data folder I can think of when the S20 is connected to my PC. This is a picture that I believe I had on a Galaxy S8 and it transferred to my Galaxy S20. I'm trading the S20 in and need to get it in the mail soon. I appreciate any help/advice you can give me.

I am running a rooted Galaxy S20 with BeyondROM 6.3 and Magisk 27.0. My banking app is working fine after I enabled hiding the Magisk app and adding my banking app to the deny list. Now the problem is that I can't start the app from my health insurance and I just can't figure out why. It's [this](https://play.google.com/store/apps/details?id=de.barmergek.serviceapp) app. Every time I'm starting it I just get stuck on the loading screen and it's even so bad that my phone is frozen for some seconds. I'm pretty sure it has something to do with my rooted device since they even say in the app infos on play store that you can't use it with a rooted app. How can I get this thing to work? Output from logcat for some seconds after starting the app: https://file.io/f0b7aTrQqm6V (had to upload it because the file is too long otherwise) In Line 94 it starts with

02-17 18:56:40.593  7429  9046 I Pageboost: start alp : de.barmergek.serviceapp

and then in lines 119 & 120 we have:

02-17 18:56:40.620  7429  7522 I ActivityManager: Start proc 17694:de.barmergek.serviceapp/u0a383 for activelaunch {de.barmergek.serviceapp/de.barmer.serviceapp.viewlayer.activities.NativeSplashActivity}
02-17 18:56:40.626 17694 17694 I Magisk  : zygisk64: [de.barmergek.serviceapp] is on the denylist

which is the standard activity to start the app and the confirmation that the denylist is working. Maybe line 193 can give some additional information:

I have a fresh Nov/Dec updated ROM Build for my Samsung Galaxy S20+ (SM-G986B). Since it's a fresh clean ROM with all necessary apps and the performance of my phone is seamless, I want to create a backup for SYSTEM, BOOT, and DATA Partitions. The problem is when I try to back up these 3 partitions, TWRP keeps throwing the ERROR 255 - CreateTarFork() > and this is especially linked to my Data Partition Backup phase. Also, when it's starting to BACKUP, a long list of PERMISSION/ACCESS DENIED messages flood the screen. I am copy-pasting a couple of lines in order to relay more accurate info. I would also upload the LOG file and link it here. BTW, I haven't installed any Shelter App thing and I don't seem to have any other user folder other than the default "0" folder name.

Over the last few weeks, my Samsung Galaxy S20 FE 5G (Android version 13) seems to lose all wifi networks. Going to Wifi settings shows no networks connected or listed at all. Every other device in the room can see my networks and others. There are no errors reported, and it's not hanging forever. I get a busy indicator for a few seconds, and then it turns off as if the wifi check just didn't return anything. If I turn on airplane mode, wait a few seconds, and then turn it off again, it can suddenly see all the networks and connects successfully. Then sometime later (I don't know how long but hours, not days), I notice that the phone is using 5G again. If I go back to the Wifi settings, no networks are listed. This happens a few times a day. I've tried restarting it a number of times and making sure the OS is updated. My wife and son each have an identical S20 and they are not seeing this. Is this a known problem? Is there a remedy short of a factory reset?

The [Open Camera](https://play.google.com/store/apps/details?id=net.sourceforge.opencamera) open-source app uses the Camera2 API for listing the available photo resolutions. On older devices such as Samsung Galaxy S8 and S9, users had low resolutions such as 176x144, but on S20 and S22, that resolution isn't available. How do I restore it?

I play some games by a developer and there is no cloud save so most players would use adb to back up and move their save files. Lately though when trying to back up the game, it's just producing a 1kb file, which from my understanding, usually means that they have backup allowed set to disabled. However, in the game's discord I asked about this and the developer says that the allow backup flag is still set to true. Is there any way on my end that I can see why the backup isn't working as expected? The command I'm using for backup is: adb backup -f "C:\myPath\backup.ab" com.default.name I am using a Samsung Galaxy S20+ 5G (SM-G986U) that has **not** been rooted. Thanks!

Whenever I try accessing download mode on Samsung Galaxy S20 FE, I click on reboot to bootloader but it takes me to a bootloader menu, where I get options like recovery mode, start, boot to FFBM, etc... yet, all of these options lead me into the main recovery mode menu. The phone is locked by T-Mobile and I think it may have something to do with it, I'm trying to flash the modem to unlock the phone. Any advice on how to get it unlocked?

I purchased 6 months before, Samsung Galaxy s20 Fe with android 12 with 128 GB internal memory and a 256 GB external Micro SD card. I am an IT freelancer professional, so I have a job is for testing 1000's of different apps, and my main work is to install some video photo editing and some technical official apps to do my job in an instant go while traveling. In Android 12.0 of Samsung Galaxy S20 Fe There is an option of CHANGE option in Settings > App> Storage to change (move) location of app from internal to SD card in Android. But its the same like as in Android 5.0, it only moves the main APK files, leaving data, cache, lib, and dex in internal memory thus occupying space in internal memory. I want to keep my internal memory free for output files of video editing to fast rendering of photo editing or video editing file on mobile. MY QUERIES:- 1. Is there any option without rooting to move the complete apps (lib, dex, data, and cache) to an external micro SD card? 2. There was an option in Android 6.0 Marshmallow for adaptable storage to format an external SD card as internal memory and move complete application files. Can I do that in Android 12.0? 3. there any developer option in Android 12.0 to force or make default installation of apps in the external memory card so that all apps are installed automatically with apk,lib, dex,data file in the external memory card but it works with only 5 to 10 apps out of 100 it still leave some part in internal memory? 4. In Android 6.0, I tried to edit the app manifest through the APK editor to change the default install location of an app to external memory. Will it work in Android 12.0? But it's time-consuming to edit every application. 5. Can we root Samsung Galaxy S20 FE and use the Link2SD app or any script in boot.int or any other new application in Android 12.0 which with its script links all lib, dex files in a micro SD card? 6. Is there any other way or method or settings options in developer options or any other 3rd part application in Android 12.0 Samsung Galaxy S20 FE so that I can move (dex lib apk data) or install complete application directly to external micro SD card and keep my internal memory free for working or output files rendering ? The reason why I still want to move apps to sd Card while having internal memory of 128GB is for testing 1000's apps and editing and rendering short video and photo editing . I know External micro sd card is slower than internal memory but the app I install for TESTING on external memory will be rarely used may 2 or 3 times a year but for testing and reporting to companies i need to keep it installed in mobile for year to give usage or some log reports and its useless to give them space in internal memory and make them full my internal memory i cant uninstall or re-install them .

I have a galaxy 20 ultra and I have repeatedly force-stopped the slack app, but it keep restarting on its own. I believe this is happening to some other apps, but I can't recall the others at the moment. Is there something I'm missing here to keep a force-stopped app stopped??

Received a replacement s20fe last week and haven't been able to reach Yahoo mail since. It times out or returns a 'This page isn't working' message. Can't even get through with the Yahoo mail app. No problems reaching any other site or service. The only problem is getting to Yahoo, with any app.

I have a galaxy S20+ and a generic USB c to HDMI cable. I connected the phone to a Philips monitor but I don't see anything on the monitor and in the USB settings I only see USB controlled by: connected device. And when trying to switch it to This device, I get an error saying "couldn't switch". Not sure if this cable isn't compatible by phones or if there's any settings I can change.

The Camera App natively supports 64MP and I have read that my phone (Samsung Galaxy S20+ 5G) may be able to go even higher. I'm taking lots of pictures in 64MP and it's great, but I've noticed an issue. The images appear to be compressed with visible compression artifacts in the lossy jpeg format. I'd much prefer that that they are stored losslessly when taken and later I can deal with how I want to compress/handle them. I have not yet found an app or setting that can do this. Most of the apps and settings I've used to get a RAW image generally work, but none have preserved the capacity to take pictures in 64MP, instead they apply to 4k, which is not what I'm interested in especially. I've tried the Camera App's Pro Mode, Open Camera, CameraMX and Lightroom. I even tried using a special build of Google's Camera App for my phone that I got from XDA Developers. And CameraMX just crashes at start.

I'm using apps e.g. Autoguard and others that record files to their directory (e.g. sdcard/Android/data/com.hovans.autoguard) and I'd like to back them up locally. Unfortunately due to the disastrous Android 11 update I no longer have access to that folder. Neither the phone explorers (also including Files by Google and the Shortcut app to Samsung's explorer) nor a USB connection helps to gain access to those files on the sd card. The Android/data folder on the internal storage can be viewed using USB or the Samsung explorer but NOT the one on the sd card. The only thing I can see is that the data folder is empty (because only root has the rwx rights). How can I access those files nonetheless without rooting the phone? I'm getting frustrated after researching for hours with no solution.

On my Samsung Galaxy S20+, the wallpaper is blurred on my home screen but not on the lock screen. I saw a similar post to this saying to change your lock and home screen wallpaper to different wallpapers, I have tried changing the wallpaper to something not blurry and it still does not work. How to prevent blur home screen wallpaper?

My Samsung Galaxy S20 battery lifetime was up to 20 hours per one charge. The I have probably installed some apps, and the time is dropped to less than 15 hours. The phone is clearly warm during the day. It is definitely doing something. How to know what namely? GSam battery monitor told it can't determine power consumption on per application basis. Can I see processor usage or something? *** I gave permissions to GSam and it showed, that most consumption is from Android system itself. Can some application add module to the system, which consumes power?

In the phone call log, what does the green network icon mean after I upgraded to Android 11? Does that mean that the phone call went through the Wi-FI network instead of 4G/5G ?

My wife and I just switched to Samsung Galaxy S20 Ultras (unlocked and purchased from Samsung.com) from Pixel 3 & 4 XL. We had no problem with having multiple connections on either device. On the S20s, under the Mobile Hotspot settings, it says > Turn your phone into a Wi-Fi access point. Up to **1** other device will be able to use your phone's mobile data or Wi-Fi connection to access the internet. Doing some research and talking to Samsung support, there is supposed to be an option in "Configure Mobile Hotspot" to set the maximum number of connections. This option is not there for us. I tried a handful of 3rd party hotspot apps and none of them worked. I also tried a few hidden settings apps and I couldn't find anything about setting the maximum connections. Is there another way of setting this hidden maximum number of connection settings?

I wanted to use the light with the camera, then it said that some other app is using the light and I see that the two icons on the right on the top are faded out. It's so horrible getting a high-end smartphone and I cannot even use the light with the camera. What can I do?
