Hi guys I’d like to ask, did you ever get an iPhone 7+ (mainly iPhone 7+ as it doesn’t happen on a 7) when after opening voice memo and clicking on record nothing is happening, (audio ic sign) you repair the audio ic (U3101) but the phone still doesn’t record memo and the speakers and mic do not work during a phone call? I have repaired the jumper even on the D12 line, checked all the top lines, replaced the audio ic for a new one, replaced U3301, tried connecting a new charging port and front cam flex but no luck. I have met with this problem at least 5 times and returned the phone to customer as no fix, but this time I don’t want to give up and want to find out what the problem is ! I don’t believe nobody else has met with this problem before.
I also have an iPhone X waiting here where the battery shows 0% and the phone shows a 0 on amp meter after a few seconds, I am planning on replacing the U3300 do you think this is the problem? Thanks
Ps: when I get an iPhone 7+ with audio ic signs and I take off the audio ic itself I can see that C12 is in 100% condition then I know that my nightmare begins because that means there’s nothing to repair as the data lines are not damaged but I run jumpers anyway but the problem still persists
