With my newly set up Pixel 7a I suddenly experience random reboots. The Shutting Down Menu (with the buttons Emergency, Lockdown, power off, Restart) appears out of nowhere. Without pressing anything from my side, it starts rebooting.
It happened already during a phone call, in other moments while I was in different random apps.
Any idea what could cause this or how to trouble shoot?
(PS: totally new to GrapheneOS for about 1 week, liking it so far, but getting really frustrated with this reboots I have since today)
