distorted speaker on speaker phone
I have an iPhone 6, I get a distorted sound out of the speaker. It works and is usable but just sounds bad sometimes. Earpiece speaker is fine; everything else OK. I replaced speaker hardware and same problem; so problem is not the actual speaker hardware. I checked accessibility settings and that is not the cause; filter from speaker to outside is clean.
Any other ideas.
Ist dies eine gute Frage?
