iphone 8 plus mic problems
Anyone with iPhone 8 Plus experience callers can’t hear them using regular phone mic? I’ve tried everything. I read posts about returning and replacing phone but people have said issue is the same.
I had the same problem on iPhone 6; in my case the bottom microphone was broken.
I solved the issue replacing autonomously the Lightning Connector Module which contains the bottom microphone circuitry (total cost 65€).
Apple didn't offer me that service and asked me 339€ to replace the entire device; if you are lucky your iPhone is still in warranty and you can ask them for free replacement.
