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.
in this list, my preference order is: 1, 2.2, 2.1, 3. As you can see, I would prefer 1 if it was available, but there is not.
Also, I criticized the appearance of the phone, not the privacy-focused OS.
