Can't call, phone goes blurry
Sometimes when I try to make a call, when I tap the phone app, the whole thing is just one big blur and so I'm unable to use it. When I exit the phone app, everything else is normal and working fine. If I press the home button twice and swipe up to close it, when I open the phone app again it's back to normal. I have no idea why it's doing it. Also, when I try to make a FaceTime audio call it only works for a minute or so then I cant hear the person I'm calling, but they can hear me. This happens on wifi so it can't be connection. If I call them 3 times, for some reason from the 3rd call the sound stops cutting out and it works, but only after 3 tries. Why???
