Oneplus 7- Random reboots - Disappearing Contacts - OnePlus 7 Questions & Answers

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

I am having the same issue. Random reboots.
I already install the 6.0 three times. one sideload and two fresh installs (full wipe + factory images). I even tried to roll back to lollipop and then update again.... same problem =(
device:
Nexus 5 - 32gb international + moto360
Sorry for my English.
I have the same problem with the Nexus 5 32GB D820.
Marshmallow clean installation ran smoothly yesterday, today began to randomly reboot.
I tried to make a factory reset and left in a bootloop.
I had to re-flash the factory image.
Let's see if it happens again.
Likely defective power button
My nexus 5 32gb is also randomly rebooting on android 6.0
The same problem with D821 16 Gb. 4 times clean installation. 1 time step-by-step installation for each part of factory image - no result. Random reboots.
There is no random reboot software bug, only faulty key

What do you mean with faulty key? Faulty like hardware or faulty like software? Cause I have my Nexus for 1,5 years and had never problems with power button at all. The problem comes only with Marshmallow.

So, there is no full restart. If you press the power button for 10 seconds, the phone will restart and you'll hear a little vibration and see "Google" logo, after that Marshmallow animation appears. Faulty key can only cause full restart effect. But in Marshmallow I have only the shell restarts, i.e. the phone restarts with Marshmallow animation (not with vibration and "Google" logo) and this lasts 3-5 seconds. This is definitely software bug.
Are we talking about M, flashed with fastboot, and almost no user apps installed and no mods (root, custom kernel, etc)?
Because if we are, there are no random reboots.

Exactly. Flashed with fastboot, no mods, no root, no any customs. Only user apps. But you are right. I'm testing all my apps and I've found 2 weather apps. They probably caused the reboots. I'm not sure about it, cause I'm looking into all my apps.
its not a defective power button.
I roll back to lollipop and the random reboot stopped.
I did another try with marshmallow, this time with sideload installation and full wipe after. At the beginning i get two random reboots, but now it seems to be ok. no more random reboots.
SOLVED. The problem was caused by Weather Live application (https://play.google.com/store/apps/details?id=com.apalon.weatherlive). With first installation of Android M I noticed that the app shows error message. Now, when I know cause and effect, I read feedbacks in Play Market and see other people reports crashes in Marshmallow with this app. So, if you have random restarts in Android M and Weather Live app installed, then try to delete it and wait if system will be stable.

I found the same issue. I'm a registered user of Weather Live, but I've found that the app is causing numerous crashes after I upgraded my Nexus 5 to Android 6 ( Marshmallow). I ran a bug report and searched it for 'FATAL EXCEPTION:', I can see that everytime there is a crash, one of the threads affected belongs to Weather Live. What I then get is a restart of the User Interface, so it goes into the 'android' animation you normally see on boot. The phone stays up because the System Uptime is not reset.
I've uninstalled the app for the moment to see if that cures the issue.
i am experiencing random reboots with my Spice Dream Uno and ended up in this forum while searching for my cause. first i thought its my device got hardware issue but it never happened before in lollipop or kitkat. it seems just like a possible hardware fault too and phone will be in bootloop , then cant even power on the display(backlight flluctuates,with black screen). when i pull the battery and reinsert after few minutes the phone starts normally. seems like Marshmallow has critical campatibility issues with some applicationsThe crash never happens in same application for me.And i have no roots ,customs etc..Came to 6.0 via OTA from lollipop.
My device dont have any issues upto now(its been an year).
I've been noticing it with a very minimal base of packages. Seems to only happen shortly after waking from deep sleep so I highly suspect doze. The phone will be fine... you set it aside... it enters doze deep sleep... phone wakes, you unlock... then bam, reboots, and enters boot loop at the Google splash screen. I've already done a factory reset, will be attempting a fastboot reflash with the new November system image today.

Galaxy S8+ freezing randomly on PIE

Hi everyone,
I have installed android Pie One UI via ODIN (Clean install) a few days ago. All worked perfectly fine, and since this morning the phone started to freeze randomly.
It happens very often, a few times in a minute and eveything gets unresponsive for a couple of seconds.
I have tried clearing the cache partition in recovery mode but the issue is still there. There were no new apps installed since the first day initial setup when I installed everything, and now suddenly I have this issue.
Does anyone know what it could be and what can I try before doing a factory reset?
EDIT: Seems that there was an issue because I debloated the firmware with package disabler pro, seems that the phone tried to start something after a few days but couldn't because it was deactivated. As soon as I re-enabled all bloat it stopped freezing.

Android 10 - random Bootloop and FC

Hello all, I'm facing an issue with my OP7pro that is making me mad
After the update to Android 10 (stable) my phone was absolutely brilliant (data formatted in F2FS) but one day, completely random, some apps started to FC. I decided to reboot my phone and I got a bootloop. I thought that a factory reset should be able to fix the issue but nothing has changed: FC and then bootloop. I tried full wipe from twrp and the msm tool as well but I'm still have the same issue (ext4 and F2FS). Any advice?

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.

Question Auto restart problem

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.
