Chosen Solution
My Iphone 6´s speaker stopped working and I replaced it. It works fine for the first 1-2 minutes, then it stops. If I restart the phone the same happens. I already did factory reset. Any solution?
Making sure to follow this guide, I’d recommend taking the speaker out again and checking the contacts underneath that connect it. Sometimes if they get fingerprint oil on them they can stop working. Give them a clean and reassemble.
