Hi All, After changing the screen of my iphone 4s, everything is working except when I use the microphone when the speaker is on. I think i’ve a bad contact because i heard some noisy sound. Do i have to check cable ? Do i have to change a piece ? which one ? Thanks for your help Benoit
Hi Benoit, Yes sir it looks like your going to need to change a cable. If the microphone is not working when speaker is on, then check for damage to volume headphone jack flex.This flex cable also has a microphone attached to it. This cable is probably damaged and needs to be replaced. Heres a link to the guide to replacing that flex cable:Here & Heres the part link so you can buy the part. Hope this works for you my friend! Good Luck!
