Hello. I have 2 problem that really getting on my nerves! 1-when I receive a call, I can't see the calling screen. I must tap answer button from notification bar to see the call screen and be able to see, ignore or answer the call! and after that, that function bar in notification still exists! and also the phone call icon that appears when I have a call ! 2- is that when I set a pin or password lock to my phone, when I have a call, I Can't see the call screen untill I give the password to phone and then doing steps mentioned before! and I don't know what app cause this problem! or maybe this is a bug!!
all this buttons not working. the only thing it does is the answer button shown in screenshot to see the calling screen!
