GrapheneOS has a convenient auto-reboot feature
TIL, I use GOS and never thought to look, I just see a banner saying there’s been updates and I’ve got “update and restart now”, “schedule restart” and “I’ll restart myself when ready” (or some such).
The main purpose of this is actually security. Because when the device is in BFU (before first unlock) state, it’s much harder to gain access to the data (without the correct unlock credentials). During the reboot, the encryption keys are wiped from RAM, making it essentially impossible to access the device, since brute-force unlock attempts are prohibited by Weaver API, which is enforced by the Titan M2 hardware security module. You can read more about this at https://grapheneos.org/faq#encryption
I will give that a read. I have been unintentionally using this feature, anytime I expect I won’t use the GOS pixel for a bit I restart it, I’ve also found it disables biometrics as a security measure. Cool stuff.
Samsung has had the auto reboot feature for a long time too.
