iPhone 7 Plus Audio IC? - GSM-Forum

productsupport · 08-24-2020, 18:02

Hello,

I have an iPhone 7 Plus where the speaker cannot be activated during calls and no sound comes out of the earpiece.
Jumper like on the photo was placed and new audio IC was installed. Unfortunately still the same error

if you have installed new audio ic no need to jump it, it will cause ic damage reball it and clean it throughly before placing new one.

YES you are right. Before replacing a new IC, you should always clean the bonding pad first. A jumping wire should also be removed.
You can check the video below for replacement tutorial of different ICs.
