Finally, your point is still completely irrelevant to why it needs to take over the entirety of the screen. It could still primarily be a phone without being intrusive when you’re doing “secondary” tasks.
Don't know about FaceTime, it's not mentioned so I'm guessing no change on that front.
No, the problem here is much simpler. iOS has features for Do Not Disturb as well as blocking spammy callers which both should help here. The problem is they just aren't implemented quite right for this scenario.
Personally I hope I don't end up blocking a family member or someone else important because my phone is slipping around in my pocket when they happen to call.
Except I accidentally hit it on an iMessage notification somehow without realizing and silenced all messages for a couple days without realizing it. Missed an important one too. Was kind of hard to undo that too.
It’s a tough UI problem.
Somehow despite this pocket dialing still happens.
I really don't understand why calls and texts don't have a default mode to only ring or pass through if they are from a contact. Depending on the government to prevent robo calling seems foolish. We need technology built into the device.
