Changed the back housing, now mic muffled when held to ear
Hello - I am hoping I can get some help with this issue. Mic works fine in speaker mode and voice memos are clear, but when I hold the phone to my face and the screen goes dim, the caller on the other end hears only my muffled voice. Seems to only happen when the screen dims, I can pull the phone slightly away and the sound is fine (to the other caller). I have tried turning off noise cancellation as well as putting my finger over the mic on the back of the screen, with no luck. Any ideas?
