iPhone 7 - Earpiece sound distortion
Hello.
I have a big problem. When i have restored my backup from iPhone 5s to new iPhone 7 earpiece sound broke... Before (when my dad was using it) it was working prefectly fine.
P.S. Bottom speaker is flawless.
Are anyone were having problem like that? Do you have a solution?
Best regards
iPhone 7, iOS 11.2.1
