iPhone 11 with very poor sound on speaker and during calls
Help!! My iPhone 11 sound quality has gone very bad . No one can hear me and I can not hear people properly either. Any idea why? I have tried to clear speaker followed instructions to turn off do not disturb etc . Desperate attempt to fix I went to foneyard shop who charged €80 and said they replaced speaker but still as bad as ever!!
iPhone 11, iOS 16
