The first couple posts here sounded like the Grandpa brigade going, "Get off my lawn with your new fangled technology I don't understand, you youngun's".
Then they'll forget their password, since they've been unlocking their phone exclusively with biometrics for the past 6 months, and don't use it anywhere else, then they'll need to take it to the store for help wiping it, and they'll lose all their data.
This has already happened to me once. Biometric security is extremely dangerous if you have no way to recover a forgotten password.
I now understand why Apple forces you to unlock your phone manually once a week.
So much this. The 3-day login prompt annoys me sometimes too, but, I don't remember my ATM card PIN right now, because I've been using the tap thing with my phone. I'd hate to forget my phone unlock code too, and I KNOW I will. Do kinda wish it was configurable — I'm reasonably sure my brain could handle 5 days between reminders. But then, I guess what's the chance I'd slowly walk it out until I
did forget…?
I've never experienced most of these issues commented on here, either — I'm using Samsung (been thinking of going Pixel next, try a little closer to pure Android — and get rid of stupid Bixby, plus having one less company spying on all my important datas. Meh, nothing's ever perfect.). I get prompts to let me know it's putting apps to sleep (sometimes I wish it'd just do it already, but it's a good thing often enough that I'm usually glad it didn't), and prompts to let me know it's revoking permissions (and you can tell it not to), and it takes all of a few seconds to flip through and ignore it (usually leave it until I'm stuck waiting for something, so it's not even taking otherwise useful time). Never had it even try to break calls, but, if you're not using the stock call app,etc., it may not know to leave it alone.
So yeah, also agree that it's most likely your crappy elcheapo whatzit screwing up Android. (Or maybe it did give you the problems, and you just ignored it without paying attention and/or understanding. "Get off my lawn, darned Android whappersnipper!")
