Question Auto restart problem - Samsung Galaxy A12

Hi I once rooted my galaxy a12 but clean flashed it with stock rom but now the phone can randomly restart even when I'm using it, i tried wiping cache and did factory reset many times and even repeated flashing the stock rom but my phone still restart itself while using it. Can someone help please

I faced the same issue, I've solved freezing the cidmanager app.
There's some apps that read the system logs, maybe you can post them here when it happens. Maybe someone will understand.

Update:
After flashing about two week ago the stock rom with magisk, the phone start rebooting itself after the startup or a reboot; even after freezing the cidmanager app. I've finally solved the issue, don't ask how it's possible... but flashing this debloater https://forum.xda-developers.com/t/wizzrom-creator.4300953/ fix this issue. No more random reboots.

Tired of SK4G rebooting itself. Suggest a ROM?

I love everything about the SK4G but the constant reboots is it's only Achilles Heel. I've tried installing the Glorious Overdose V2 ROM on it, and the phone has seen overall improvement but the reboot problem has not been fixed and everytime I open an application or playing games it will freeze and then reboot. Can anyone suggest a ROM they're using that has helped with the reboots occurring all the time?
Try GingerClone, it's one of the lighter roms.
trying a different rom might help, but chances are if you flashed a rom and the problem persists, then flashing another rom may not help. I had the same problem with the stock rom. my phone rebooted every 15 minutes to a half hour for almost a whole working day. finally I shut the phone off, booted into CWM recovery, clicked on advanced, and ran fix permissions. I suggest that you not use a program or script to boot into CWM, because I have tried that and it doesnt work. after I ran fix permissions, the endless rebooting stopped. if you like the rom you're on, try fix permissions and see if it works. you really dont have anything to lose. if it doesnt work, just flash another rom. I recommend fix permissions a lot, because it has worked for me many times.

[SOLVED] Bootloop even after flashing factory image

Hello guys,
I need some help please, because I'm out of ideas.
The issue:
I was using the Cataclysm Rom for months without any problems. Today I restarted my phone (I do this every other day, when it gets a little bit slow) and it stuck in bootloop.
I tried wiping dalvik/cache, doing a factory reset, reflashing Cataclysm, nothing worked. So I decided to go back to stock (using http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701)
and I'm still stuck in a bootloop every time. I can access and use fastboot/stock recovery in the normal way, but it won't boot..
Could someone please suggest what I could do?

[Q] Random reboots and apps crashes

Hello.
I'm experiencing random reboots and apps crashes. My phone was rooted a month ago. I tried to wipe partitions, make a factory reset, format partitions, flash stock 1 file and stock 4 files (with pit file inside). Sometimes the phones freezes and I need to restart it, sometimes it's rebooting by himself. When I'm working with it about a minute, apps start crashing.
In Samsung servicedesk said that the phone was rooted and they can't help me.
So, maybe somebody has any idea what to do? Maybe there is some app to log the crashes and I will see the problem?
Thank you.

Debugging J7 Prime Restart issue

Pardon for a long story but someone gave this Samsung J7 Prime(SM-G610F) to me with an issue "An Error Has Occurred While Updating The Device Software". So I gave Samsung Smart Switch a try sadly they removed the Initialize option and old version don't seam to do what it suppose to do so I wen to a traditional Odin flashing. I then look for a stock rom for the phone that I think is the right one. Started with android 6 MM region pakistan and flashing went well. I was able to use it for a good hour or two until I notice it restarted by it self, then it keeps doing it 10-20 seconds after booting up. I though its the firmware I'm using so I went and look for Oreo version this time I region india (I don't know if region matters). So I flashed it again and tested the device again. I'm still able to use it for a good while till it restarted again. I then keep testing it to see what may be causing the problem. I notice that when the WIFI is on it just crash the phone to reboot so as soon as the phone reboots I turned the wifi off and it didn't crash anymore. I then factory reset the phone cleared everything, wipe cache then installed benchmark tools first. Thing I notice is it crashes when Google Play store is trying to install or download something. I tested it a couple of times to see when it crash and it does crash when downloading or installing something. I was still able to install 3Dmark and run it with wifi off. It completed the test without crashing so it couldn't the processor issue. I then look for another rom and tried flashing it. This time I had issue with it failing at system.img even if I use recent rom that worked. I then keep trying till flashing TWRP worked and flashing the rest of the rom is fine again.
What bothers me is why doesn't it crash during the first couple of hours. I've search similar issues and they say it may have been and app issue. I've already disabled bunch of app but nothing changed. Run the phone in safe mode but this time instead of crashing and rebooting right away it freezes for a few seconds. I suspect if google play or something being an issue since I've tried disabling it and it didn't crash for a couple of hours. Looked for allot of related thread but none of them seam to solve my problem.
I suspect either its the rom that I'm using and it can only be fixed by using the original rom, or its having a memory issue but don't know how to pin point it. Anyone can suggest on how I can debug this? I'm used to debugging things in real time and my knowledge with android is a quite slim but as a programming understanding the errors won't be a problem. I hope.
Edit: Hmm. Does copying kernel log with TWRP work or the kernel logs get overwritten every time the phone reboots? Because I see the kernet logs but don't see anything failing except for something saying SHUTDOWN but I don't think thats it. :S
Still no reply. :S I think its /system dismounting it self while doing a write operation. but it doesn't trigger until a certain amount of time after the phone is flashed or factory reset. I have to go to recovery and mount system back but that only happens on marshmallow. over version it remounts it self after the random reboot. After factory reset I'm able to install COD mobile and play a couple of match. after a long while it just decides to reboot.
I also tried z3x and after reading PIT from phone OK. the phone just reboots and flashing completes without it doing any flashing.

Oneplus 7- Random reboots - Disappearing Contacts

Hello,
Since June 2020, I have been facing erratic issues with my oneplus 7.
- Started with a reboot loop. Did a factory reset, things were ok for a day.
- After that the phone randomly reboots atleast 2-3 times a day. Factory resetted many times. With a hope that beta build may solve the issue, installed BETA software from oneplus. But no luck. Problem continues.
- Recently noticed that sometimes, all of a sudden my contacts disappear. Wiping cache or disabling and reenabling Google contact sync brings them back.
- Wipe Cache data doesnot help in resolving this issue of random reboots
- Occassionaly apps like Whatsapp, Phone dialer or Launcher crashes. Wipe cache temporarily resolves the issue, but it again comes in a day or two.
I have not installed any unauthorised apps and all my apps are from verified google play store...
Totally frustrated with the problem of the phone...
Anyone has any luck in getting a solution to this problem?
Try latest open beta
Thanks for the reply, but I am already on the latest beta
This is because maybe the last ota installed (before this problem started) was not done porperly. Try full reset your phone and flashing the rom again through fastboot or you can try going back to h2os (which is the main rom when all the OnePlus phones are made with then switched to o2os) and then switch to o2os which will be a clean flash. You can find the procedures in the forums. I faced your problem a lot because I switch roms a lot and tried out these which solved mine
