The other day I had my IPhone 6S’ screen replaced after I broke it and since then my earphone’s jack just won’t stay in place. When I put it, it just comes out after a few seconds. What do you think the problem is?
Take out the screen and verify the components. If it is genuine or MFI touch screen, replace it perfectly. Don’t again prefer that guy who fixed it earlier. If he can’t fix a screen, he is no a professional. DON’T pressure the screen to lock the head jack. It might get cracked.
