Evening all! Lucky I also noticed difference in quality control between my two phones, you are not alone in your observations, here is hoping this one will work good as a phone! On your market issue, when I first got my replacement, it loaded everything flawlessly. However, when I unlocked and rooted, it reloaded nothing and acted similar to how you described yours. I am not sure why, but even though it was the same handset, it behaved two different ways. On a positive note, I have not had the one way audio issue for almost two weeks; of course I still don't trust it but I can hope!
