Constant random reboots (already did factory reset) - Nexus 6P Q&A, Help & Troubleshooting

Hey guys,
HALP
Is there a good way to pinpoint exactly why my phone random reboots? So far I've already done a factory reset and it hasn't helped. Even with only installing basic apps (google apps, twitter/insta/snapchat/evernote)
Even with none of those apps installed, it would still reboot.
Tonight my phone was at 48%, I picked it up, sent a text message, put it down, picked it back up and it was on the Google splash screen rebooting.
I downloaded Catlog, will that help diagnose, and what should my settings be?
Thank you so much in advanced for any help yall can provide
PS, my phone has always been stock and never modded in any way.

Have you tried flashing the factory images, along with formatting the internal storage? Factory reset was a good idea, flashing the factory images is the next step. Do that and don't install any apps, if the problem remains then you're probably dealing with a hardware failure.

Is your case "accidentally" holding down the power button? This was my issue.

Boot the phone in safe mode and check if the phone still does a constant reboot... in case it does.. there might be some hW issue as you already got the factory reset part going...
SENT... isn't that enough

Thanks for all the responses. I ended up losing patience and sending it back to my phone insurance for testing/replacement. They were the last to take it apart for a screen repair so I'm hoping to pin any hardware issue on them and they'll replace it under the warranty of the insurance plan I purchased with them.
If they offer me a definitive diagnosis I'll update as well.
Cheers

everytime i get a txt msg the phone resets to the splash screen

any idea why? it just seemed to start doing it oneday, im also getting a lot of launcher force closes. ive uninstalled many apps and im still getting it, i cant figure it out. im about to do a factory reset but really dont know how and also dont know if i will lose the paid apps ive downloaded and have to buy then again, please help! thank you!
You will NOT have to rebuy apps you have paid for. As long as you log in with the same Google account you will be able to redownload them.
As far as the resets, I have no idea. I am also getting the FCs with the launcher.
First... download Astro File Manager. It allows you to backup apps... not sure if you can back up paid apps, but maybe you can.
Then do a hard reset by going to Settings>Privacy>Factory Reset. Or you can turn the phone off and power back on holding the Volume Down rocker. That should solve the issue, but if it doesn't, it's time to call HTC and RMA the phone.
i ended up resetting to factory, im not sure why it was doing that

Can't seem to wipe this Spring Galaxy Tab

I've been given a Galaxy Tab by my office to play with for a while for some various development projects we have coming up and to evaluate its use. Initially another employee had it, but he quickly lost interest.
Problem is, his Gmail account has been tied in as the primary account for the system, so I can't use my own Market apps, etc. No biggy, I'll just wipe it, right? First I tried a data wipe from recovery, but despite claiming to be successful after a reboot it's still got his account in there. So then I did Privacy/Factory data reset, but that mostly just reboots into Recovery where I do the same thing again and still fail to wipe his data off the device. I then pulled the memory card and formatted it and also reset with it out, but no improvement. I finally downloaded the stock image and flashed it with ODIN and STILL his account remains.
So... any thoughts on what I could be missing here? I just want this thing back to pure stock so I can put my own account in and work with it as though it were new.
I am having the EXACT same issue on a Verizon Tab...
No one has been able to help me.

Glad I'm not alone, but sorry to see you've not gotten anywhere either. This seem absurd...
Agreed. I thought I was the only one.. It just doesn't make sense.. I flashed mine using heimdall and still the same issue. The only problem is that mine force closes when you do anything.. So if I can't restore the software on this it's absolutely no good to me.
Yeah, same here. Nearly none of the apps functions now after the reset. This is absurd.
I'm in the same boat. It's very frustrating. Sprint was not able to help me. All he could do was walk me through the factor reset. I downloaded a Market app that bugged out something and now I'm getting quite a few force closes.
I just notice that if I merely restart this thing is loses all changes I made since I last restarted it, adding back any apps I uninstalled, removing accounts and WiFi settings I installed, etc. This is screwy. Wondering if there's a hardware problem with the flash memory.

Listen to this, even more crazy than that... After my last unsuccessful wipe, I decided to just uninstall all of the applications. I just did another factory restore for the heck of it. Now ALL of the applications I uninstalled are back!.. AFTER the factory restore!
I think the only sure way to fix the problem is to get a zip file of the stock firmware and load it through the recovery screen.
Edit: since it put the applications back on there, I decided to try your situation. I uninstalled all of them, turned off the Tab and then back on. All applications are back.

It seems incapable of now making permanent changes to the flash memory. This is really screwy and annoying.
I am having the exact same issues. We are all in the same boat.. I have a $30 reward if anyone can fix this..
Any updates from the others with this problem?
I received 2 more Tabs today for my sales reps. They both work fine as far as factory restore. I noticed that the bad one goes to the boot loader when I initiate the restore through the Android software. The new ones do not. They format and reboot back into the operating system. Sprint is going to exchange the bad one.

Thanks for the comparisons. Mine also goes to Recovery mode when I initiate a data wipe, so clearly it's the same situation. I'll have to see how mine was acquired and whether an exchange is an option.

Screen flicker issue... Hard reset?

Hello, all.
I am having an issue with my Iconia A500. The screen will quickly shift screens back and forth on its own for a while and then it will freeze. I was hoping to reset, but since I cannot get it in to any of the menus, I am unable to do so.
Is there a way to hard reset without booting the device up using the reset hole or another way? Anyone ever seen this screen problem?
Thanks for your help.

I found that holding the power button down for about 30 seconds will force a hard boot.
(This is specifically mentioned in the manual downloadable from Acer's site).
As for the "flickering" and refusal of the A500 to stay asleep, it seems to be related to background wifi activity. Disabling wifi before putting it to sleep will make it stay asleep. At least that happens with mine.

By the looks of things it seems like the music app is launching then quiting and launching and quiting... I don't see a screen issue but rather some kind of corruption or instability. Try a reset or uninstall/update that app.
i tried many reset but it doesn't worked. i tried to do the update.zip but unsuccessfully. i try to push the power button +30sec it doesn't worked too.
and i can't update or uninstall the app because i can't push on the tab because of the constantly launching/quiting.
Ya... I don't know man.
Is there anything you might have done to cause the behavior? SD card installed with music on it? rooted? Installed (bad) apps?
Maybe someone with more knowledge has some ideas.
You could always try to return it and get a new one...?
None of these.
Stock, just few minutes using (i was configurating it). No root. No apps installed, just an automatic update of google maps.
I'll see with Acer if they can give a solution

The news:
Tab was down. Acer's warranty sent me a new one. I don't know what was the real issue because they don't said me any information.

Trusty Note 4 Booting Issue!!

Hey guys, I have had my Note 4 for about 3 years now and it has never done me wrong. However, things have taken a turn for the worse... I started noticing a few days ago that it was slowing down on me, I mean, really slowing down. Big lag times when it comes to swiping to open the screen, or changing between apps, and the occasional self-shut down when the battery got down to about 15-20%. I had been putting off doing a self-update for a while, and when I finally had time to do one tonight, in hopes of cleaning it up, it is now lying on its death bed
I do not think the update ever finished (my phone is not rooted) but I was desperate enough to even do a factory reset and that has not fixed the issue.
Here are the symptoms:
As I go to boot the phone, I get past the Samsung Note logo and it looks like it is about to load properly, but then I get a popup that says "Unfortunately, the process com.android.phone has stopped" I hit ok and it keeps popping up again. I can't bypass it.. Then after I get passed that for a split second, another popup comes up that says "unfortunately system UI has stopped" It prevents me from getting to the home screen, in fact the screen behind it is black.
I have tried the following:
Clearing the cache partition from the recovery screen
I have done numerous hard restarts
I have gone through with a factory restart
That is where I have left off, and lost most hope, was with the factory restart. Now when I turn it on, I get past the logos and I can see in the background the page you would get as if it was a brand new phone (it says "Welcome! Preparing you device for first time use.." etc. But I can't do anything about it because I am still getting the same two popups that prevent me from doing absolutely everything!!!)
I have read about this happening and people seem to be able to fix this by accessing certain app setting and either resetting them, or clearing their cache. However, that is not an option for me because I can't get that far. I think something must have went wrong during the update...
Please help with any advice you can think of. I have been putting off rooting this phone pretty much because I was afraid of royally f****** it up, but at this point I am willing to try anything.
Thanks,
Eric
Hey guys, does anyone have any suggestions for my issue?? I am about to go out and buy a new phone, I have no idea what I can do to fix this. I have rooted it using Odin, but the popups are still occurring. I can't get the popups to stop, and they are preventing me from doing absolutely everything.
Is there anyway I can get it to go back to complete scratch? Again, I have done a factory reset, cleared the cache, rooted using Odin. I have done everything I can think of/what I have read I can do. I am willing to try anything at this point.
UPDATE: At this point my phone is on, and the only error message/popup I am getting is "Unfortunately, System UI has stopped." Behind that popup is a blank, black screen. The only option I have is to click ok, and the screen remains black.
Temporary solution that might work- Try logging in safe mode: Switch off the phone. Power it on and as soon as Samsung logo appears, release the power button and press and hold the volume down button. Release button when you see Safe Mode on the lower left corner of the screen. Try uninstalling all user apps in safe mode. To get back to the normal mode you can drag down from notification and disable safe mode.
You could also download the latest software for your model from samfirm and flash it via odin after factory reset. Could be a permanent solution.
why you just flash last frimware from sammobile,it will solve all your problems
SOLVED!!!
Alright guys, I was able to solve my problem, all thanks to this thread:
https://forum.xda-developers.com/note-4-sprint/general/stock-tar-odin-flashable-t3250864
I had already tried flashing a fresh stock rom, but to no prevail. I saw this thread and thought, hey why not give it a shot, and bingo! After downloading the .tar file for marshmellow and launching it through odin, she was good as new! So if anyone seems to have a problem with the system ui or the process phone.android popup, I suggest that thread.

Strange instances of multiple reboots!

This is really starting to get on my nerves now. Ever since I got my new S10+ from AT&T, it's occasionally done this thing where after I reboot the phone, I unlock it, and it briefly says "starting phone" on the home screen, and then will mysteriously do a quick reset, where it skips the AT&T logo and jingle, and just shows the Samsung splash screen , then takes me back to the lockscreen and it's usually fine after that.
However, Just now I decided to reset my phone, like one should do periodically, and it did the strange double reset after unlocking... Then when I unlocked it, after the "starting phone" message I tried to open a browser, and BAM! Quick reset again! Unlocked, let it start up, tried to open an app, BAM quick reset again after the screen briefly shifted from landscape to portrait mode (even though I was still holding it long ways in landscape position). Its never done this before and I'm getting concerned. It's never randomly reset while using the phone, this only happens right after a reset.
Any ideas? I've already tried wiping partition cache after big updates, doing soft resets. I'm worried that I'm going to have to end up resorting to a factory wipe, as others suggested I do when I was having battery drain issues on the ASD3 firmware, possibly because of restoring everything from a backup of my last phone when I got this one. Because supposedly restoring from backups from AT&T, Google or Samsung has caused all sorts of problems for people. I really don't want go wipe everything and spend hours try to get it all back on here manually if i don't have to.

Had an issue with this early on but seems to have been fixed at some point, I'm I'm exynos though so probably not much help!

Dang... So it does appear to be an issue experienced on both Exynos and Snapdragon variants. I wonder if there is or will be a fix for this. I've been asking around and haven't gotten many responses about this problem at all. I'm concerned because it seems to be getting worse than when I first got the phone.
I'm having the exact same problem. Sometimes it goes through quick reset, full reset, a couple more quick, then back to the Verizon logo, then starts up. Opening an app at that point usually does another quick, then full, then everything works. Glad I'm not the only one, but I haven't found any solutions either.

Mine does the same. Unlocked bought directly from Samsung. I don't reboot the phone very often so it doesn't bother me that much.
