GrapheneOS, a privacy and security-focused Android-based operating system, has posted a series of tweets on X suggesting that Android should introduce frequent auto-reboots to make it harder for forensic software vendors to exploit firmware flaws and spy on the users.
Autoreboot is a thing on Samsung phones for quite a while, you can even choose the days of the week and the time for the reboot.
Not for a while, at least not on their flagships.
