Wait, this is a bug? Same thing happens to me but I thought Apple made the change on purpose. If you tap the contact circle (picture if your contact has one) the phone controls, including the hangup button, reappear.
I do think it's a bug, but thanks for this info. This is a game changer for now!
Hangupgate strikes again. I think at this time we are waiting for a update from Apple.
Even with the latest updat this week I still have this bug. I can't believe this. I just want to hang up my phone. This is getting crazy.
verison after version and they still haven't fixed this. so upsetting.
