I am a Sprint customer looking for an Android phone for basic functions. I am trying to choose between the Hero and the Moment. I have 1 of each right now from Sprint, on the 30 day trial. Here are the challenges I find with each. Does anyone know of any fixes for these? Hero 1) Phone hangs up during calls because of lack of proximity sensor 2) Speaker phone wont turn off once activated, unless I end the call 3) Vibration mode is very weak and basically useless. Cant feel it in my pocket 4) Sprint Navigation does not work Moment 1) Battery runs out before end of day 2) Bluetooth is spotty and wont always connect 3) Web navigation not as smooth as Hero. thanks!
