This “incremental backup” is literally the same thing that’s sitting on your phone and from where the messages are read from and where new messages are appended to. So it’s technically is being read from there, e.g. if you receive a message, uninstall whatsapp before opening reading it, re-install and restore from backup, you’ve technically got a message from google’s server.
🙄 I don’t know why you’re making up these crazy scenarios. This is not the same. This scenario that you constructed is the same as restoring from a backup. It’s not at all “technically the same” as “receiving” the message from Google, in the normal way that the app “receives” messages. It’s not the same code path. It would go via the backup code path in your example, and it would have no idea whether or not it was an old or new message. It is however practically the same, given that you “have all your messages in the end”. But please stop dragging this backup thing further – you seem knowledgeable enough that this is not technically the same thing. Let’s move on from this point. 👍
Nope. I can literally hand you my unlocked phone
Oh, okay, yes, that is much different, sure. If you just hand them your unlocked phone. That’s not how I understood the scenario at first though. I thought you said they somehow bypassed the lock screen, indicating to me that they would somehow be able to do so with everything else behind the phone’s security system as well (e.g. they know your PIN, have a way to unlock using your biometrics, or something more advanced). So yeah, if we’re changing it to just handing it to them now, that’s different of course.
