There's a company called Cellebrite that makes phone dumpers. They take full snapshots. All phones except GrapheneOS are vulnerable if the phone has been unlocked after it was rebooted (After First Unlock - disks have been decrypted). Some are also vulnerable Before First Unlock. So just assume if they have your phone and it's not Graphene, they get a full memory and disk dump.
