For some strange reason, I noticed exactly this aswell (one time, this morning). I was working out and my phone laid on the table, when I saw it lit up because it restarted for no reason.

I guess it's a software bug.

And no, there was no automatic system update - I checked, I'm still running the old version.

I don't have any issues. Do you have the November update yet?
I had the November update and all apps had been updated as well. It would freeze and then reboot.

I did a factory reset and did not restore any of my apps, just ran it with the factory apps, and it still did it. Since no one else is having the issue, I'm feeling confident it was a bad unit. I had the 128 gb version.

It's back to the pixel 5 for another week or so. I had to exchange that after I got it too because of a bad proximity sensor. Either I just have really bad luck or Google needs to tweak their quality control department.

If you're having issues, do yourself a favor and keep an itemized list (on your device, word doc on pc, somewhere) and notate the following for each occurrence:

-date / time
-the fault (self reboot, major lag, over heated, fast battery discharge, etc.)
-what you had to do to clear it (rebooted, closed app, powered off/on, etc.)

When talking with Google about a replacement, having THIS information ready to read off will make it extremely hard from them to give you any grief about you needing a warranty replacement.

An itemized list of faults is MUCH better evidence that you need a replacement than "well, it rebooted a few times last month" :p

Weird unexplainable OS crashes like that are usually due to faulty hardware, potentially RAM
I am inclined to agree here, but my years of working with Windows and Android incl. rooting and using custom roms and kernels want to disagree here. There can be half a gazillion software based reasons for an OS crash, especially with a buggy release like Android 12. Not sure if you participated the beta, but it reminded me of Windows 11. There was a buggy beta build with about 100 bugs, they fixed 20, called it a day and released it. Now we new P6 owners can play beta testers Volume 2 for Google.

One very important thing here is also: Did you guys set up your phone "clean" or did you copy over your old phone by cable or did you use backup?

Any of these things can cause issues.

I, for example, used a cable to transfer all file and apps from my P4 XL to my P6 Pro. It's possible that this is the rootcause for some issues, or maybe it's not. Maybe there are even problems that occur only if you transfer your files from specific phone models to this one, you never know.

Sure, but the OP stated the crashes are happening right after a factory reset, and anecdotal evidence on this thread suggests it's not widespread. It does point to some sort of hardware problem.

I'm having exactly the same issue!

I got the phone today and booted it up for the first time. I selected my language and as soon as I pressed get started it froze, then got stuck in a bootloop. I fixed that by factory resetting from within recovery.

Once I'd gotten through the setup it crashed again when I clicked on the apps button in the optional setup. Because of this I factory reset and set the phone up for a third time.

Third time I got through setup with know issues but the phone freezes/reboots roughly once every two hours. I've been searching all day to see if anyone else has mentioned this issue.

I guess this phone is going in for replacement. Does anyone happen to know how long that takes/ if I'm going to be without a device for long?

Well, I had the 6 Pro for about 36 hours. It kept rebooting randomly, even after a factory reset, so it's going back for an exchange.

Has anyone else had this issue?
I just had 3 random reboots today. Phone just laid on the side of my table on my laptop, doing nothing. It was in the span of probably ~10 minutes each reboot. A strange observation I made - now that I removed my phone from the back of my laptop and laid it directly on the table, no more reboots. Maybe it's a coincidence, maybe it has something to do with the magnets of my Laptop (has quite a lot inside). Not sure what to make of this. It kinda feels like a software buggy-thing, but it's odd that it sometimes just comees and goes. It also only appears to be in absolute idle. I had my phone working yesterday for about 12 hours, incl. using it constantly with navigation, and it never faltered for once. That's why I'd say it's a software thingy, if it had something to do with hardware, it would reboot/fail when under load. But it doesn't.

Had 4 total reboots as of now (had the phone since 27.10).

First reboot was yesterday (28.10) morning when working out, phone laid idle around, booted up.

And now again 3 reboots, morning, laid around, did nothing.

So I've had probably a dozen in two days. I take my phone out of my pocket and attempt a fingerprint unlock only to be told that my PIN is required after a restart. At first I wasn't sure if it was actually rebooting until last night. It prompted me for my pin and upon entering it, the screen locked up for about 20 seconds and it rebooted.
This morning I woke up and was yet again greeted with the "PIN required after restart" and less than 20 minutes later it was the same thing. Only once hav I witnessed the "G" boot animation, but everytime I see my UI loading. So I'm not sure if it's always a full reboot or some times it's just the UI crashing. Everything on my device is stock.

Did you transfer your old phone over with a cable, or backup, or did you start "fresh"?

Maybe we can narrow it down if it's software or hardware problem.

    Just wanted to pop in and give a little follow up. Received a replacement device 2 days ago. I did migrate everything over from the device that had been randomly rebooting a minimum of 4 times a day, but typically more. This new device has ran flawlessly for 2 straight days without issue. Its my opinion that theres some sort of hardware issue on some of the devices causing this problem, but i very well could be wrong.

    These are my first experiences of any shutdowns. Any crashes? Nothing else to report. I've not experienced any others

    To be fair, they've not happened again. And yes, these things should not be happening at all. I'm waiting for all sorts of apps to update properly for Android 12 and the usual bugs. Thus far, I'm quite convinced it's all software related.
    I just talked for a while with a Google rep and he said that they are not aware of any reboot problems, no people over at Google Forums have reported such a thing. "We do not monitor Reddit or XDA" - so he said he opened a support ticket to the responsible team and they would look into it, he also asked that I / we report/feedback this under -> Settings -> Tips & Support -> Feedback.

    We also talked about a lens flare problem, that at least the Pixel 6 Pro has. If you shot some photos where the sun is directly shining into the camera, you might want to re-check them. Most of mine have either some sort of big circular green dot in them, or a big beam of light like in a phone with a very bad HDR processing. It seems to be some sort of software glitch, he also reported that.

    So hopefully those things can get fixed.

    My replacement P6P arrives today. Keeping my fingers firmly crossed this ends my reboot problem.
