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

Try restoring and reinstalling iOS through a computer this sounds like a software problem

its audio ic problem,,

Yes update isn’t satisfied why
