iPhone XS Max Microphone doesnt work
When i try to record voice on voice memos or a call on loud speaker the microphone only makes noises.
Recording videos or receiving calls its normal.
Has the phone dropped down? This looks like a symptom of a broken connection between control and data signal. Another case with a similar symptom is the corrosion of the tape with the charging port. There is one of the three microphones, a speaker port. Anyway, you have to disassemble the phone, check a tape flex or/and correct the motherboard soldering.
