[Android 8.1 Oreo] Random reboots in my second time install - Nexus 6P Q&A, Help & Troubleshooting

I installed 8.1 last week. Everything was working smoothly. Was trying magisk youtube mod. Screwed something up. Phone went into bootloops. Reinstalled everything .Wiped data. Now my phone reboots randomly. Everything stock .Rooted with Magisk. Mainly it happens whenever i launch a new app(An app which was not launched before). After few tries, the app opens up and doesnt' result in reboot.
Any ideas what could it be ?

You should of wiped system and cache also might be your problem. Also if you where using any substratum themes remove then manually as well. Not sure if they would cause reboots.

FC's are one thing but random reboots are a completely different animal. I would completely wipe the phone and apply the latest factory image using flash-all.bat. If that doesn't fix it you may have a hardware issue (eg. degraded battery).

Wiping caches helped
I'm running SUPERXE-8.1.0-OPP5.005_v1.5.1.
My 6P was going crazy, restarting every 5 minutes or so. It rebooted so quickly it felt like a soft restart, so I thought powering off and rebooting to recovery using the power + down volume to clear the cache in TWRP would help.
Cleared system and Dalvik and powered down. Full reboot and (for now) it feels much happier and hasn't spontaneously restarted yet. That was about 15 hours ago.
Hope I didn't just Jynx myself, but I think it helped...

I've flashed the final 8.1 images to upgrade my 8.0 unmodified system. Now I've random reboots, usually when I've leave home to go to work or vice versa. Something related to wifi, that I'm connecto on both my work and home?

Same here I had to factory reset I'm having a feeling it's going to happen again. I am on factory, rooted with magisk. I always use SuperSU not saying that is what it is however it did happen when I got home from work and just kept rebooting before I could unlock.

Cyanogenmod 10.1 Rebooting Issue

Hi, I bought my GS4 two days ago and immediately rooted it via the motochopper method, and then installed ClockworkMod via the loki method. I then installed the then latest nightly (cm-10.1-20130530-NIGHTLY).
Now I understand that nightlies come with no promises of work, but I was just wondering if anyone else was experiencing a rebooting problem on their device. Mine reboots randomly, and often. Multiple times a day. On two occasions it has gotten itself into a reboot loop (starts rebooting, gets to the lock screen, and immediately starts rebooting), in which i needed to pull the battery. Still having the same issue on the May 31st build.
I'm just hoping that someone else has this issue, other then just me. Any ideas to fix it would be amazing!
Use a touchwiz rom, problem solved.
CM is nice for sure but, it seems to always be broken.
Fixed!!
After dealing with the issue for a few more days, it continued to get worse. I could no longer uninstall apps (every time I did it would reboot), and it became more frequent, even with updating to the most recent nightly every day.
I finally got fed up with it today. I did a complete wipe of data, cache, and dalvik cache, and reinstalled the latest nightly (cm-10.1-20130530-NIGHTLY). After installing gapps i turned it on and am no longer experiencing any issues!!! Even after i reinstalled all of my apps and restored the data using titanium. Hopefully it has fixed it completely, only time will tell over the next few days.

[Q] TMo Note 3 Deciding Rebooting is the Only Solution

Ended up "solving" this by doing a stock restore via Odin, after which TouchWiz would never load an icon (crash loop). Reinstalled TWRP via Odin, then flashed ViSiON X N3 via TWRP.

Morning guys,
I've had some reboots lately and a weird situation last week where I had to do operating system surgery to get the thing to boot at all.... HOWEVER things were going quite well for some time, and it's been rooted and non-stock for months.
Nevertheless I woke up this morning and it was off, I figured the battery had died so I swapped batteries... It boots, it gets to the launcher and it loads the app icons then freezes and reboots... over and over again.
edit: to be clear, as soon as the slider bar touches the right-hand side the phone freezes, the vibration holds for several seconds, and then the device reboots. obviously not what one expects from this operation (having done it before). I was able to wipe the Cache separately... trying to wipe the Dalvik cache all by itself in an advanced wipe does this reboot thing.
OK I said, i will just clear and reflash this.
Going into TWRP, attempting to do a factory reset wipe just freezes, buzzes, and reboots immediately (to the not working OS)... in order to make this all stop I pull the battery, because now the button on the side won't seem to do a hardware poweroff for anything. Just ends up resetting the current reboot.
--
Any advice would be helpful now. I was just going to say forget it and grab the tiniest ROM i could find and ride it out until I upgrade the device, but now I'm just concerned with getting it active. The rebooting in recovery when trying to do a wipe does not make me feel too great. First and only problem I've had with android roms.
Thanks,
Chris

Stock SM-G935T- Dozens of apps crashing and random reboots

Have T-Mobile version of the S7 Edge, stock, never rooted. Yesterday Samsung apps did a few updates, and a few hours later the phone began to have:
(A) apps crash with the message "Unfortunately X Has Stopped"
and​(B)reboots, some of which are stuck on T-mobile logo (until I reboot the phone a few more times)
A lot of the apps that are crashing are official Samsung/Google apps, including Play store, Google Play Services, Samsung Pay Framework, com.samsung.faceservice, and etc. Usually this happens when opening a new app. Sometimes it happens in succession and a dozen messages will pop up over each other.
The reboots happen right after the phone freezes for a few seconds (often does this when entering settings > applications. Often the reboots get me stuck on the tmobile logo, with it vibrating every ten seconds or so. Holding power + left vol to reset it works half the time, then it boots normally.
The only other symptom I've noticed is in recovery I see the following message: "dm-verity verification failed"
---------------------
Things I have tried which have not helped:
1. Going into Google web services, Play, Play service and wiping cache.
2. Rebooting into recovery and wiping cache.
3. Rebooting into recovery, and doing full wipe/factory reset.
3.1. Made sure to wipe cache before and after​
4. Using Odin to flash stock firmware
4.1. Used the right firmware, (G935TUVU4APK1)
4.2. Made sure to wipe cache + factory reset before and after​
5. Using Odin to flash stock firmware + full nand wipe + repartition
5.1. Made sure to wipe cache + factory reset before and after​
Still have the same issues. Not exaggerating, each time, as soon as the phone boots past the tmobile logo, and gets to welcome screen, some of the app crashes begin (most consistently com.samsung.faceservice, and almost every round, the phone reboots at least once before I finish setup.
---------------------
I am completely out of ideas. haalp
I am experiencing something similar. Android 6.0.1, with December security patch (7 is not out yet for my Norway TEN phone..). Has happened since purchase.
Every time I update applications in the Play Store, the entire phone freezes.. sometimes I also get a horisontal line across the screen, about 3mm in width. After about 20 seconds the phone reboots into the Samsung logo and starts booting up. At that point, it will reboot about 3-20 times depending on the app that I update. Sometimes clearing the cache works, but only about 1/4 times. It gets insanely hot if connected to a charger (about the temperature of burn marks on skin).. I tried master reset, and it vanishes for a little while before it returns, even if I don't install any applications at all. Been handing it in to Samsung a few times, but they always just tells me that either it is normal, or nothing is wrong.. I don't really know what to do anymore. I am suspecting a hardware failure that happens when it is put under stress.. but since it happens 1 or 2 times per day, the workshops don't have the patience to just keep testing it hard, instead they just run a normal stress test and say that everything is fine.

If that all three are as you said then your NAND may be damaged.

When WiFi is turned off I get 'Unfortunately System UI has stopped'

This is on two standard Galaxy S5's, with standard ROM, etc - not rooted, or anything else.
Every time I turn off WiFi, or enable Mobile Hotspot, I get 'Unfortunately System UI has stopped'.
To fix I have to Power off/on the phone.
(Turning on WiFi is no problem, just turning it off.)
I have gone into 'Safe Mode', and same issue, so it looks to not be a bad App.
I have also uninstalled 'Google' updates, and again no change...
Any thoughts?
All of a sudden my S5 showed the exact same error message for no aparent reason... I didn't do anything, and now I can't use my phone at all because of that bug. It happens on every boot so I can't even unlock my phone. Tried reinstalling everything, ROM, recovery, kernel, with/without root = still same, what just happened here??
EDIT: Same thing if I'm in Safe Mode -_-
Seeing noone knows a solution here's what I did yesterday.
1. Backed up all my stuff from internal storage to the sd card
2. Did factory reset in TWRP recovery
3. Flashed completely stock official firmware from Samsung
4. Waited for it to boot up and try to restore some of my settings (it restored all folders on their places, made same amount of home screens as I had before the reinstall and downloaded all of my previously installed apps from the Play Store, ofcourse without the cracked ones, and it also restored most apps' data as well so it's not as bad as you may think to factory reset and reinstall everything)
5. Started rooting, flashing TWRP again, installing Dolby Audio, Xposed and everything I had before, took me one full day to set it up as it was before.
Now when I set it up I always make a nandroid backup from when things are working fine, in case it goes crazy for no reason again... Good luck!
when the wifi radio is acting weird, a dirty flash of your current ROM susually fixes is as its probably a radio issue. Id do that before doing anything drastic like the boot-n-nuke Odin flash and starting from scratch (which will fix that issue)
I don't think I have a ROM issue, as I have two S5's, and both have the same issue... and both are standard ROMs.
I will do a factory re-set on one at some point, but this looks to be a 'simpler' issue.
I have tried a full Cache delete, as well as other 'clean' processes.
Nothing works.
I tried to re-flash my stock ROM as @youdoofus said but still had that annoying popup. Try everything you can think of, if all else fails, reset.

well, you can wipe cache, and dalvik 3x each (not kidding about the 3x each), then dirty flash the rom, pray to the gods of android, reboot. If failure occurs, its Odin Nuke time unless you want to try to flash an individual radio file by itself (not recommended)

Freezing and rebooting

Classic "my phone keeps freezing and rebooting". I am quite in the know about flashing roms and such.
It started on the stock firmware 6.1.1 (i think it was). I dd factory resets, cache wipes the lot. It would still randomly reboot.
So i flashed Telstra version of 7.0. Still froze every now and then. Did the same things as above.
Flashed TWRP and wiped everything, flashed Renovate Rom and the bootloader for it, Still did it. Numerus factory resets and wipes of everything. It would freeze at any point from startup, to having setup the phone and making phone calls or on facebook or whatever. It would even freeze in twrp, or loading twrp.
I found that the data partition was corrupt so i re partitioned to ext4. Still nothing. I reformatted every partition so the phone was a complete brick with nothing on it and after flashing clean again it would still do it.
Whats the issue that I'm missing, or is there a way to log so i can find where it keeps getting stuck? It gets hot and blue light flashes and i have to hard reset it or sometimes i have to let the battery drain so i can turn it back on again.
pls help?
Hmm i will give you an advice so you dont have to wait for your battery to drain...just press volume down and power button for like 5 secs and phone will force boot. Anyway back to your problem...did you tried flashing latest stock samsung firmware?

This advice doesn't work with my phone even with holding the buttons for 30 secs and more. For rebooting I can only wait until the battery is completely drained. With little hope for another way shortening time to the next reboot any help is appreciated.
Same here...experiencing the same prob...
Same problem.

Sounds like you need your motherboard replaced i had the same issues on marshmallow thought the nougat update would fix it but realized it was a hardware fault not software..left it in store to get fixed and on repair sheet it said faulty motherboard..

As i know some S7 have motherboard hardware problem, mine has too, what help? warranty and they replaced motherboard. But if you root, you can say good bye to warranty, they look at knox first with this problem.
