Pixel 10 Pro - Random reboots with screen off (build 2026032001)

zionakamoto

Device: Pixel 10 Pro
GrapheneOS build: 2026032001
Issue: Random reboots/crashes occurring several times a week

The device crashes and reboots randomly, mostly when the
screen is off (in pocket or idle). No specific app seems
to trigger it - it happens without any apparent pattern.

I have been running GrapheneOS for less than a month on
this device. The issue started shortly after installation.

I attempted to capture logs via Termux (logcat) but the
process is killed during the crash so no useful output
was captured. I have not been able to generate a bug
report immediately after reboot yet.

Is this a known issue? Is there anything specific I can
do to help diagnose it?

Was the device running in s stable fashion before GrapheneOS was installed?

zionakamoto logs are available without iTermux, go to SETTINGS>SYSTEM>VIEW LOGS

Johnnyloans not necessary to use ADB and not recommended for security reasons. GrapheneOS provides access to logs natively as mentioned here MetropleX

Sending a bug report to one of the developers (not me) will be useful. It has app crash/freezing and kernel logs from previous crashes/boots

Yes, that resolves the OP's issue for capturing recent logs; however, those logs are cleared when the phone shuts off like the OP mentioned--not helpful for the crash.

The device crashes and reboots randomly

Would have to have a bug report which can also be done inside of developer options. It contains logs from previous boot cycles of the phone, when the crash happened.

Settings > system > developer options > bug report

Could it be due to Auto-reboot? Settings > security > exploit protection > auto-reboot
Child/person holds down the power button for a minute or selects reboot?

If you think the phone errored/crashed, and you want to report it to a dev. (I don't speak for GOS, but i'd imagine this method below is approved)

Make note of the date and time range when the reboot could have happened along with your timezone.

Do next process for a bug report and save it somewhere when it finishes via "share" on the notification:

Johnnyloans Settings > system > developer options > bug report

Create an issue on this website:
https://github.com/GrapheneOS/os-issue-tracker/issues

Say your phone randomly rebooted overnight, it isn't due to the auto-reboot timer (if true) and you can provide the bugreport.zip file in an email or DM. (It'll likely have personal info.)

Tonight I noticed a restart on my P10ProFold (the device was asking for the SIM card PIN when I picked it up this morning, which only happens after a restart).

Johnnyloans okey, I will save the report file if this occurs any other time.
Not, it's not due to autoreboot or other people holds power button or force reboot

The bug report contains past issues. You are able to do it any time. Up to you.

GrapheneOS build: 2026032001
Issue: Random reboots occurring multiple times per week

The device reboots randomly, mostly when the screen is off
(idle or in pocket). No specific app triggers it.

After capturing a system log immediately after reboot,
I found the following boot reason:

reboot,longkey,pmic_cold

This was found in the log at this line:
DropBoxMonitor: skipping last_kmsg, its boot reason
is reboot,longkey,pmic_cold

Device has been running GrapheneOS for less than a month.
Issue started shortly after installation.

Is this a known issue with the Pixel 10 Pro PMIC firmware?
Is there a fix or workaround available?
