And from my reading, helps secure against a situation where an police officer (AKA attacker in the US apparently…) coerces you to unlock the phone (or perhaps even just takes it off you in a locked, but active state), and stores it in a faraday bag with a charger. They do that to keep it ‘alive’ so their experts can break in - a dead-mans reboot can help circumvent even that (as it will just reboot and restore itself to an encrypted rest state, which is much harder to attack)

Yeah, seems like its a move to follow apple after custom ROMS offering it as a security feature (Im on GrapheneOS and had it set for a while)

Thanks for the clarification, I forgot that (somehow)

After a reboot all the data is encrypted and needs a pin/fingerprint to unlock. So if it’s stolen (or feds get it) a planned reboot resets it to a highly secure state that is much more difficult to hack into than when it’s just locked from timeout. Edit: removed fingerprint, corrected below.
