Using this device for 3 weeks and I've been experiencing this since last week. It hasn't happened during the day yet but at night it does. When I wake up my phone is either at the 'unlock sim card' screen when it's connected to my charger or just off and I have to boot it up. The latter is very annoying as my alarm doesnt work then.
I fear it's a hardware (battery or mobo) issue but hope it's a software one as it's happening only during the night so far. I'm in the process of unlocking my bootloader as of an hour ago and hope a clean install / flashing an older version of miui or flashing miui.eu may fix this.
I have low hopes for Banggood customer service where I ordered the phone...
Edit: please do chime in if others have experienced this or have advice on troubleshooting like logging the crashes or smth, I'm a big noob in this regard.

It happens to me randomly. No specific time of the day, but not always, its been getting frequent though. Before its like every 2 to 3 weeks, now i'am having it every week. There are also times that the phone becomes hot, not very but noticeably hot, then it freezes so I have to force reboot it. If someone out there knows whats going on please enlighten us.

Okay it seems I was pretty dumb and had the auto-schedule turned on under Security -> battery -> settings -> schedule on/off. Had it set at turn on at 00:00 and off at 07:15. However, I thought this settings was to turn on and off the battery saver mode lol. I turned the whole thing off and hope I won't find my phone rebooting at night now.

Did you find a solution? It has been happening to me too. When I am playing a game, or doing skype calls, or just randomly, It happened a few times also when I tried to use google photos, it is more and more often.

Yeah, see my comment above. For me I actually accidentally set it up to reboot. Random reboots often point to a faulty battery, possibly loose connectors.

I'm gettin random reboots / restarts...

Really weird, doesn't seem to happen when the tablet is stressed or something. On the other hand happened more often with heavy memory stuff like big pdf's and when i live youtube videos loading, maybe I have an issue with the 2 gig's of ram? it's there any way i can test that?
Sometimes the tablet isn't doing anything an restarts. Like when the home screen is blocked. Anyone else had this problems?

I would suggest you try flashing the nexus 10 factory restore image and see if that fixes things. If it's still randomly rebooting I'd send it in for a replacement.

I'm getting the same, please keep us updated because I'm hoping it's a software issue...
Got some of these too. One of these was really freaking, I had to force a reboot. I definitely think it's software

You can see the reboots I'm getting on here... http://imgur.com/704mp.png
i have also problems. Sometimes when i usw Chrome, the Browser don't react and then the screen goes black and i have to push the button on top for five seconds to reboot my nexus. Had this problem three times. I,m hoping for a fix...
Happened to me twice already! Wtf

Guys, I think found a pattern: Each time I get a reboot seems to be related to the wifi connection, like if the wifi freezes the tablet. Pay atention to the wifi settings when you get reboot / restart the tablet it's like searching the wifi connection like crazy, but, if you reboot normally the wifi it's already connected. Seems like a clue to me.
I played like 4 hours yesterday Chaos Rings. Seems like a really advanced game to me, so the stressing test is passed. It's not related to stress IMHO.
I've been getting random reboots too. Took several attempts to get all the way through setup right after taking it out of the box. At first I thought maybe I just hadn't given it enough time to acclimate to ambient temperature or something, but problem has persisted even after flashing the factory image via fastboot. Haven't noticed a correlation with wifi, but does seem to happen mostly when idle. Have also had a couple freezes and shutdowns, too.
Guess I'll be calling Google this morning... Argh.

I actually haven't had any reboots yet. I haven't stressed it with any games, but installed my normal apps and used it for web browsing/xda for a couple hours and no problems for me (yet...fingers crossed)
Called Google, and after being on hold for almost 1/2 hour (I'd imagine they're pretty swamped) explained the issue as well as what I've already done to try to resolve it (factory reset, fastboot recovery image flash) and they started the replacement process without any additional questions.
Just my luck, the first time in ages that I buy a device the day it comes out, I end up with a dud... Hopefully I get the replacement quickly!
I'm really nervous at this point. Mine is perfect aside from a piece of dust in the screen. Google is sending me a new one, but now I am afraid I will get one with more issues.
no more reboots here. But i think it's a software problem.
I have had two unexpected reboots. One was about halfway through ep. 1 of Planet Earth. I don't recall what I had running the other time.
I'm still running stock 4.2, unrooted.
Somebody postes useful info.

Mine rebooted then rebooted three times in a row before even getting in the desktop.
+1 Reboots
3 reboots in the past hour! Location svcs disabled.
Sometimes under load (gaming), other times just random.

Random shut down

Today I picked up my phone up to send a text and it was no longer powered up. It had randomly shut down.
When I switched it on again I noticed it has lost its battery stats so looks like they were reset or lost. There were no user apps installed on the phone either.
Have you had a similar experience?
You could try to reset it or take it back. Could be defective!!!
Was it somewhere it was hot? Maybe the phone got too warm and hit the shutdown temp?
Honestly hard (read impossible) to tell you what happened. Have any more info / logs?
I haven't had any issues with heat or shutdowns at all. I get 6+ hours SoT every single day at 75% brightness. 100% stock and unrooted. I use my N5 for all the modding aspects like V4A, Xposed, etc. I want this one for Android pay.
Anyways my uptime has been running since I unboxed it on 11/9/15. No issues.
I actually had it reboot in my pocket yesterday on the first day i had it but I already installed a custom ROM so no testing it out now.

It was only room temperature. Here in England at 18cc so not too hot, but good point.
I read about the same thing happening with a N5 and it turned out to be a defective mother board.
Guess I should return today then... Bummer
If you just got it, might want to see if it happens again. I had one random reboot the first day and its been fine since.
My phone has started doing the same thing. Twice in 3 hours.
Same here...... 3 times reboot..... And now 2 times shutdowns.
I started having random reboots after I installed greenify. I tried several settings but had the same problem. It rebooted 5 or 6 times a day. I uninstalled it and haven't had any more problems.
I had my phone shut off yesterday and wouldn't boot until I plugged it in (it was at 80% battery). I then noticed that once it booted, it had deleted all of my paired Bluetooth devices.

Was just having the same problem but it was happening every 30 seconds to a few minutes. Deactivated greenify's device admin ability and now it's gone. Hopefully it stays that way, though if it comes to uninstalling it, that's fine since there don't seem to be as many background apps running on the 6P compared to my verizon LG G4.
Nevermind had to uninstall it.
Shut down, and a little warm
My nexus 6p shut down nearly every day, I just picked it up and it was shut down, I looked under battery and I could see it has been shut down for hours.. hope somebody knows anything about this problem.. I don't think a hard reset will help, because when I got the phone I installed all the update to Android 6.01 (MMB29M) and then I did a hard reset to make sure the phone was as good as it could be..
But maybe I'll try one more hard reset, just to be 110% sure

I'm having this problem too. It happens a couple times a day, and I think it always happens right after I pull it out of my pocket and try to unlock it. I'll feel the vibration from the Nexus Imprint fingerprint sensor, but then the screen doesn't turn on. So I try the power button, and nothing happens because the device is suddenly off. So then I hold down the power button to turn it on, and it boots normally.
Someone mentioned this happening with stock software, which makes me think it's a hardware problem, so we'll need replacement devices. However, I do have Xposed and GravityBox installed, so I need to rule those out first by removing them for a while.
I've had the phone for two weeks now and so far this happened twice.
The only two things that come to mind:
- enabling SRGB in the dev settings
- using a bluetooth headset
Has anybody pinpointed whether this is a HW or SW issue!?
How common is this ... I've seen ppl complaining in this thread and in Reddit also on random reboots as well
Thx
Still happening...
I am having the same issue. Did the reset to factory with no help. Phone was not hot, was sitting on my desk with 81% charged battery. This is the 3rd or 4th time in a week it just shuts itself off for no reason. Has anyone found anything??
I'm having this problem too, now on DVP 3 it's even worse. But I notice today that alarm clock works, but the screen won't. So I think is a SW related, the screen won't wake up, and after a while if you press the buttons the phone reboots. Anyone have e ideas how to fix this?

facing this problem since may security update, on purenexus , dirty unicorn and rr rom. dont know if it hw or sw or simply power button getting pressed accidently.
I think I need to reopen this post, coz' I've been facing thif problems for so many times this week so I google around and come to this post.
Has anyone come to a workaround or point out if it is software or hardware related yet...? If it's hardware then I think I'm gonna go for a replacement then!!!

Random reboots with multitasking

Hi guys,
I've had a super weird issue with my phone for the past few months (although I don't remember exactly when the issue started happening). Basically, my phone randomly reboots when there is a chathead/bubble/etc on the screen. This problem happens when I use Facebook Messenger chatheads, bubbles by LinkBubble, and chatheads by YAATA. I don't think it's a program-specific issue, nor does my phone reboot every time I use those apps. It's very inconsistent and hard to predict.
Have any of you encountered this problem? Any ideas for what is causing it and/or how to fix it? It's really annoying to have my phone randomly reboot itself multiple times each day. I know I could just uninstall the three apps that seem to trigger the reboots, but I really like those apps and want to find a way to keep them around.
Have you over clocked at all?

No. The problems initially started when I was on stock, unrooted. I'm now on CM12.1 and rooted, but the random reboots are still happening.

Lock screen freezes

Hello XDA,
This is my very first community post so please don't judge if I do something wrong here
Let's cut to the chase. I am a happy owner of the OP6T 8/256gb phone and I am super happy with the device, however, I have been having an awkward issue. From time to time, couple of times a day, my phone would not recognize neither double tap nor the power button to wake the display up. Usually out of frustration I press the power button couple of more time, but nothing happens. Then after 3-4 seconds the display wakes up and even opens the camera (because I pressed the button couple of times, but not in a fast way...). Afterwards, the phone works without an issue until same thing happens hours later.
So my question is if anyone is experiencing anything similar and found the culprit of it?
If you need any additional info on my settings, please let me know!
It is not the worst thing that could be happening with a new phone, but you know, one expects the brand new phone to work 100% of the time
Looking forward to your replies and ideas!
Many thanks,
Donatas
It's happened to me only recently. I'm rooted with magisk 17.3 running a few modules such as dual speaker, Google dialer framework and viper. I was on stock kernel, but switched to Smurf kernel without any hiccups so far.
Well I am full stock, even with stock launcher... That's why it bothers me that it is happening:/ thanks for your reply

Yes this has happened to me, glad to see I'm not alone.
It happeneds randomly, like few times a day, not too frequent to render the device unusable, but enough to be irritating - especially when it's a brand new device.
My setup;
*Rooted
*Magisk (viper & YouTube vanced module)
*Stock kernel
I'm at a loss as to what's the cause of this issue, it's very weird, it could just be an oxygen os bug that will be resolved by OnePlus. Who knows. Hopefully if more people comment about this here - we will eventually get to the bottom of it.
So far on 9.0.6 build the issue appears to have been fixed, I have not had any random temporary lock screen freeze.
Can anyone else confirm this?

Glad to hear it is fixed for you!
Unfortunately, since the update, I already experienced it 4 times...
Even more so, sometimes now the phone would randomly stop playing music from Soundcloud (I dont know about other apps, i predominantly use Soundcloud).
I love the phone but it is a little shame that some of these features are failing
Hope 1+ will fix this and we all be happy!
Yeah, sometimes my device doesn't respond to double-tap. Usually I just have to double-tap again and it wakes up. I haven't noticed the issue with the power button, but I rarely use that to wake the device. I did have a situation recently where the device wouldn't wake from a screen tap no matter how many times I tried. I can't recall if using the power button woke it or if I had to force a reboot. But that's only happened that one time.
I just updated to 9.0.6 a day ago. I don't think I've experienced any non-wake issues since then. Really haven't been paying that close attention, I guess.
I believe I am having this issue. I just flashed 9.0.7 from TMO and I'm rooted with magisk v4a and vanced. I get random freezes where I can't tap anything on my screen. I have to turn it off and on with the power button.
I experience this as well. I thought it was just an isolated thing, and it's kinda annoying...
It's very irritating. I'm trying to pin point it and so far I notice it with Firefox and Spotify transitions.

Mi9T random shutdown

So this happened like a week ago and I thought it was some weird coincidence but it happened again twice today. The phone just randomly shuts down, it only seems to happen while playing pubg. I'm in the middle of a game and the phone just turns off but it makes this noise like when a circuit shuts down it's not a noticeable noise but still quite weird. It happened a while ago in the middle of a game and today I opened a hotspot for a friend while playing at the same time and it did this...I also turned the hotspot off and played and it did this again.
IDK what to do...possible defective unit ? Or maybe it's a problem with the game itself ?

I guess u should go for a replacement or a refund and I think it is a battery cable problem
Yeah I think it's a battery problem too since it only seems to happen when the battery drain is high, my device is only 3 months old so its still under warranty.
I'll monitor it throughout this week, if this persists I'll definitely swing by Xiaomi.
(Device is completely stock btw even the bootloader is still locked)
Did you manage to find the problem? I got my 9T pro for around 4 months now and it also started to shut off multiple times a day. Not during any particular heavy loads or apps/games. Just random it shuts down. Really annoying and I have no Idea if this is software of hardware related problem.
