My wife's iPhone 6's back camera quit about two weeks ago. From last week my iPhone 6's built-in speaker becomes very weak (volume hardly audible even at max setting). The timing of both occurences with iPhone X release makes us suspect whether this is a strategy to promote the new phone. I brought my phone to a local repair shop today who replaced both speaker and connection cable without any effect on my volume problem. The repair tech suspects it could be software issue. This reminds me that the problems appear after recent system update. It seems that we have no choice but to upgrade to a new phone. Conspiracy to push people to upgrade? Any others have similar issues?
