iphone 7 recurring audio error -need advice - GSM-Forum

boneksl · 07-16-2019, 08:09

I have a problem with iphone 7 phones that come to me for a typical audio bug.
After de-soldering the system, clean connections, apply new balls to the bga chip. I correct faulty connections with a small copper wire, for example from a speaker from conversations. Connections secure the solder with a mask. Unfortunately, many phones are still coming back with the same fault. Do you have any advice or do you know what I can do wrong?

Have you made all four jumpers?
Have you tried to change the IC?
