Microphone not working ONLY on video recording DX HELP!
I'm pretty confused and somewhat dismayed. I have just repaired my friend's mom's screen on her broken iPhone 4S. The screen works beautifully, can make calls and receive calls, and hear the microphone on both ends. Voice memos work. Now, the problem is, as I am about to give the phone back to my friend to give to his mom, it is not fully working. The microphone does not work properly when recording a video. I have searched and searched and searched for a solution or a similar problem as to this, nothing. The dismaying part is that I am going to be assertive and tell him what is wrong with it, and not leave it unfinished. Without a solution, I am very upset with my work as I try to handle something like this in the most professional manner. I am very very confused and would really like some advice, I don't even know which microphone to replace, or if it even is a microphone?? it shouldn't be because the microphone works! Someone, with experience please respond! is there an ifixit phone number I can call?
Is this a good question?
