Resposta para "Microphone Issues When Calling"I’ve never experienced any hardware issues of any kind in the 11 years of getting their products. Started with iPhone 4 after hearing a buddy rave about his 3. My favourite is the 6 cause of separate earphone jack. Got a brand new 8 with 2 year contract. Thank god I didn’t buy used cause after only a month the microphone not working. Apple store scanned and said hardware issue. And will replace since it’s under warranty. Huge inconvenience. I guess iPhone quality is going downhill. A word to the wise: NEVER buy a used iPhone!
