Il Mio Problema
The front mic was bad so I had to order the whole part which included the front cam, mic, proximity sensor and light sensor.
La Mia Riparazione
Went well. Very tricky to do since the parts are so small and I don't have very delicate fingers. But I'm tech savvy and patient, and eventually got the different parts seated in their holders and the back plate back on.
Turned the phone back on and everything worked like a champ!
Glad I ordered a used OEM part. Didn't want to mess with a third party piece that might have had poor camera resolution or other downgrades.
Il Mio Consiglio
Go with the OEM part, evening used. They all get tested before being sold anyway and there is also a warranty on everything they sell.
