Random shutdowns

Siloi

Hey all, new to Grapheneos. Bought a Pixel 7 pro and put the os on the device a few months ago. Its been great until recently. In the last two weeks I've been experiencing random shut downs seemingly out of nowhere. The device will shut down while in my pocket or while actively used. Its pretty consistent and does it a few times a day. Aside from reflashing the stock is to test, not sure if there are any options I have to determine why on Graphene.

Any advice? Any logs I might be able to check? Basically trying to rule out a software issue before reaching out for warranty with Google.

Thanks in advance.

You are not the only one Siloi

I've started to have those issues as well, maybe for a couple of weeks/month or so. They are not that often and I've found no connection to anything I do or don't do whatsoever, they seem to be happening somewhat infrequently and at random times. Sometimes once every day or so, but now I've not seen it again for days. Who knows? Anyways it has been over 10 times, I've disabled auto-reboot and was/am using the phone everyday so it can't be that either. I'm on a Pixel 6a btw. I was also wondering might it be a hardware failure but now I'm not so sure..

Maybe there's something to investigate from GrapheneOS side of things?

Siloi Though not as common, I have also started to observe black screens on a rather regular fashion with Pixel 7 with GrapheneOS, which worries me a little bit. The phone does reboot after a while when it happens, and I also have the haptic feedback from the power button, and the touchscreen seems to work also during that short period.
It has so far happened three times...

UseLinux Many GrapheneOS releases ago, on a 3a, I had a couple random shutdowns after using the camera, which I don't do often. Once I found the phone still running but warm.

Since then when I'm done using the camera I explicitly shut down the app. I've had no more random shutdowns. On the other hand, all of the software is different and so is the phone, so maybe by now I'm merely acting on a superstition.

Well that's disappointing to hear. Guess I'll try to go back to stock os and see if it reoccurs there. Before I attempt, either one of you try this yet?

Personally I wouldn't place that much weight on a single anecdotal report (even though it's from me). Is it plausible that your camera app is running in the background before the random shutdowns you have seen?

Updating the post since this has been a while. I recently reflashed the phone with the stock is from grapheneos after the crashing / shutdowns became so numerous that I was unable to get through a 20 minute drive without it shutting down 3-4 times, everyday it was occuring anywhere from 10-30 instances. After going back to stock, I have experienced 0 random shutdowns over the last week.

Hope there's an opportunity to determine what is going on based on it but I unfortunately can't go back or risk it due to the interruption to important calls and texts.

Siloi Thanks for reporting back! It is understandable that you are keeping your primary phone running an OS that works for you.

Maybe at some point a second device may be cheap enough for you to try further experiments.

I had it this morning as well. It turned black and inporeable for a few minutes. Only felt the haptic feedback when trying to hold the on/off button. After a few minutes it showed the google & graphene logo and booted back up. Had this happen once before a month or so ago. Pixel 7, very happy with Graphene overall though. Just hope that it won't one day go black and just not start up again because I don't think u could send it to warranty then either?

If its broken, why wouldn't you be able to send it for warranty?

csis01 If 3rd party software caused the phone to forever hibernate I assume they wouldn't want to deal with that. Though I know nothing about this, it's purely me throwing my thoughts around

Uphill1945 A 3rd party OS won't cause the bootloader to mess up. As long as the bootloader is working, it doesn't need warranty. Just reinstall the OS and/or factory reset.

I had a Nexus 6 which did that.

It drove me back to apple for a while, but I returned to Android.

One of the sages said to try putting my phone into 'LTE only' mode when I squawked about this. It might be worth trying.
