iPhone 7 Plus ear speaker eventually stops working after replacement.
So I had an iPhone 7 Plus come in for a screen replacement the other day. Customer tested the phone before he left, was able to make a call, use camera, etc. Came back in a couple of days later because he couldn't hear out of the ear speaker. In fact, when he made a call, he didn't even have the option of putting it on speaker phone as that was greyed out. He could however use it on blue tooth. So I ordered a replacement front camera, OEM. Replaced it, the phone was working well again. All components seemed to work. Customer came back in today, same thing had happened. Any suggestions?
Ist dies eine gute Frage?
