Below are basic features that should be implemented in an iOS 13 release in a matter of a maximum of 2 months, as I do not feel like we should wait until iOS 14 to see these basic features implemented...
1. stop regular phone, and FaceTime audio/video calls from hijacking my entire screen and rendering my phone unusable. And,
2. add the option to "ignore" calls, to allow calls to ring in the background, in the notification center, for instance. As of now, pressing "Decline" will notify the caller of my intention to ignore them as they will either go to voicemail or be given the notification that "___ is unavailable for FaceTime". "Ignore" will allow ignoring without the other party knowing that they were ignored, as a call will continue to ring until it is naturally sent to voicemail or continue to ring in the case of a FaceTime Audio/Video call.
It is 2020 already and we have been dealing with the above for how many years now?!
