Hi, I replaced my iPhone 7 screen and everything was working fine. After I updated the iOS to 13.4 if I’m correct,the microphones stopped working and the speaker was greyed out during calls. So I can’t call anyone. What can I do? IC chip might not be the problem.
Audio IC chip has pulled the C12 pad and will need to be reballed with a jumper wire ran. iPad Rehab and STS Telecom are good choices for board repairs such as this.
