Issue #1: People are constantly complaining that they can't hear me when I call them (or when they call me). This microphone issue has been discussed at length by others on the net, with the consensus being that that the problem is caused by the noise cancelling mic on the back of the phone. The solution apparently is to root the phone and turn off noise cancellation, but I don't want to root my phone. Anyone have any suggestions? Issue #2: The speakerphone volume is too low. Volume when playing songs, etc. is great. Any suggestions on this issue? Thanks!
