9 iPhone 5s slow or hangs when making calls
Hi all
Having an intermittent issue with a iphone 5S when making calls, when you press the green call button it either temporally freezes, make the call but screen dosent change from the dial up key pad and calls in the background or dosent call at all,signal strength is good, I have done updates, DFU, changed the screen, even changed the antenna and still has an intermittent calling issue.
Any help would be appreciated
Ist dies eine gute Frage?
