I keep telling the kids "stop downloading screen lock apps. If you forget the password, you'll have no phone. You don't need one because the phones don't leave my house"!
So what happens? I turn a phone on and it's screen locked!
Anyways, as it happens, all my devices are logged on my Google account.
I accessed "Find Device" app. Selected mentioned phone and clicked on "erase device". "Are you sure you want to factory reset device"
I can't wait to see his face when he sees a different lock screen with "please enter password to access android" on it. 😀
