iPhone 4S low speaker volume
I continue to have an issue with low speaker volume out of the ear speaker. Speakerphone and headphone volume still loud as normal.
I have got 3 replacement iPhones from Apple, but the exact same issue happens everytime. The ear speaker volume is awesome when the phone is brand new, but over the course of a month or so, the volume continues to degrade to the point where I can barely hear the other party.
I saw the thread about a bug, and the fix was to go to 'settings' and lower the volume there, then manually raise it with the side buttons...that didn't work.
And the screen is NOT clogged up with dirt.
This is REALLY frustrating, as it's done this same issue with 3 phones in a row. Any help is appreciated.
iPhone 4S, iOS 6.0.1
