All my 3 internal microphones gone after battery replacement, i open and close, it works for a while and then again…only microphones, speakers, even the upper one, work, recharge works, but not microphones, can be caused by bad contact on the spring connector?
sounds like it could possibly be audio ic or damaged component when changing port , first though would be to re-seat all connectors, then hang a new charge port in, if that doesn’t fix it.
