iPad mini 1 lỗi micro facetime 
step 1: Measure the resistance at 3 sockets. If lost -> tracking and lifting the wire (yellow frame) on line.
step 2: take a look at the resistances (green frame) -> replace same value. It has a small value so short lifting is OK.
step 3: ’cause voltage 1v8 Micbias use voltage 1v8 together with main source, so don’t be worry ’cause lose 1v8 ->lose source too.
Note: Ipad mini lost mic, most of them were error at the wire (yellow frame) near socket. if it wasn’t error -> replace audio code, beside there wasn’t had mise errors.
