The device restarts constantly randomly - Samsung Galaxy Note 9 Questions & Answers

Hi .
I have a problem that I encountered on Android 9 and 10 which is that the device is constantly restarting randomly .
I do not know the cause of this problem ?
Is there a way or application to find out the cause of the problem ?

backup you data to pc and do a full hard reset as it is necceary after update to newer version of andriod. i.e andriod 8 to 9 and 9 to 10.

I deleted the data from the recovery .
Do I have to do a factory reset ?
And I haven't updated from Android 9 to 10

Ok. i thought you upgrade andriod verstion through ota update. Its fine if you deleted data from the recovery.
try this to confirm wether it is hardware or software.
Go to recovery and delete data and cache. reboot phone and do not restore your data and applications. use it for 1 day and see if it restart or not. if not then try restoring data and apps one by one to check which application is causing this.

[Q] All apps are crashing

Hello,
I have problems with my i9000. I am using MIUI 1.11.11.
The thing is that since yesterday I have serious issues with my phone. It happened before upgrading to new version of MIUI.
All apps started to crash, there is no exception. Starting from Google Services Framework untill standard bluetooth app. Every single one. I can't even check any e-mails, messages, I can't even make a call because calling app crashes too. I can't receive any calls at all. I rebooted phone, cleared caches, upgraded phone to MIUI 1.11.11 and nothing. I can't use my phone anymore.
When I pressed "Report problem" I saw for a second log with problem it said something about "data I/O error".
I think the issue is somehow connected to sdcard since I had problems with it before. It was always hard to connect my phone by usb cable. Actually... it was always hard to DISCONNECT my phone. I had to wait looong minutes (about 20 or so) till it finished disconnecting.
If you guys could help me, I'd be glad.
Thanks in advance,
v.

I'm sorry to tell you that you'll probably have to do it (factory reset) since I've had the same issue and I had to do it.

When downgrading Android versions you have to do a factory reset or you'll get a bootloop.

Galaxy Note 9 Mid screen not respond to touch

Hi I hope you all will be fine.
Model# N960U1
Yesterday I updated to andriod pie. After updating I got all new look nd software but one thing note that the mid section of my screen didn't respond to touch. Along with that some times screen freez nd after ten seconds it come back to life. I have tried wipe cache and safe mode start but nothing help. I tried another method like backup data nd factory reset after that phone start working normal but after twelve hour phone of use and encounter the same issue now u can't do that every time to reset. Please advise a solution..
Does it happen if you boot in safe mode? If not there might be some app conflicting. If it is still occurring in safe mode then try factory reset but no data restore. If the issue comes back contact Samsung for repair.

Have you tried backing up only your messages, files and photos without the apps and system settings then factory reset? Do that and redownload all of your apps fresh from the playstore then redo all of your system settings all over again. That could help a lot.

Question Redmi Note 11 NFC (spesn) stuck on "bootloop", how to backup my files?

Hello!
When I unlock my phone (Redmi Note 11 NFC, version is V13.0.12.0.RGKEUXM, there's an update available V13.0.13.0.RGKEUXM but I can't do it because of this problem), a few seconds later it reboots into the recovery menu. I've searched for a fastboot ROM of the update so I could manually update it, but it isn't available (only "recovery" version). I was wondering if I could backup the files on it before trying to wipe it, but if I don't need to wipe it, it'd be even better. Is it possible? If so, how? (I've tried rebooting it many times, "safe mode" that didn't actually do anything, connecting to MiAssistant which didn't work, activating Airplane mode, uninstalling recent apps.)
Same problem, started today. Already tried wiping data and the problem persists, so don't bother.

The system does not boot after automatic update

Hi
I have a very strange case with my P20 PRO 128GB Single Sim. About a week or two ago, I got a message that my phone found a new system update. I was very happy because I was still stuck on 9.1.0.311 because my phone never got the update to 10.
What was my surprise when it turned out that the update has exactly the same number that I have now uploaded to my phone.
I found that I did not have time to install the update yet, so I kept delaying it.
I was also supposed to do a data backup, unfortunately I didn't have time.
Last night my phone was updated. Unfortunately, it did not start normally after this update.
Constantly stops on the screen:
Your device has loaded a different operating system.
To learn more, visit:
http://zh.ui.vmall.com/emotiondownload.php?mod=restore
....
Your device is booting now ...
Then it goes to eRecovery.
I tried to do Update and recover system in this eRecovery, unfortunately after connecting to Wifi and trying to find information, I get the information Get package info failed
The Emergency backup option does nothing. The phone restarts and goes to the first screen Your device has loaded ...
I wanted to repair my phone via Fastboot & Rescue mode and HiSuite, unfortunately I get the information that "System restore is not supported on this device"
If I hold Volume Up + Power on the turned off phone, I enter the menu where I have the option Update mode and Clear data. In Clear data, I chose Wipe cache partition and then Safe mode, but it didn't help.
I wonder if by Update mode and, for example, through Memory card / OTG update mode or USB update mode, I would be able to restore the system and recover the data.
What do you think about it? Is there any chance to recover data (mainly photos and videos) or accept the loss and try to do Factory reset?
