Advice before buying the lightning connector/reballing
Hey guys, I know this has been asked a lot of the times before but I really wanted a second opinion.
I bought a used iPhone 5 which has no sound during a call. Now, I've tested all 3 microphones (front and back camera + voice memo + Siri + VoIP) and the earpiece (voice memo + VoIP) and the proximity sensor (voice memo) and they all seem to work perfectly.
The other answers suggested that the lightning connector be replaced, although another suggested reballing a certain IC. Which one do you guys think would be the solution for me, given that all the hardware seems to work just fine.
Thanks a lot!
