From what a friend working in a state police cyber crime office says, "Cellebrite can't currently, unless its a Graphene OS user that's far behind on updates"
They also said iOS is equally safe unless you're an update or two behind.
GrapheneOS seems to do better than anything else at preventing AFU exploitation based on the leaks.
iOS will be quite good BFU but on iOS the auto reboot (brings phone to BFU after 72 hours without unlocking) is, well, 72 hours. On GrapheneOS it's 18 by default and can be as low as 10 minutes.
Good luck on that, Cellebrite :)
