Kyocera Mako S4000

This phone is going to come available to Pocket shortly. I know I will be getting calls regarding this phone. So I was curious in knowing what are the most common issues with phone? Any advise would be appreciated.

Please, any one in the Detroit area, do not buy this for Metro PCS, it was recalled for a lot of problems and who ever has them for sale are more than likeley older models that weren't sold. I have no idea if we're getting them in any more, i sold 12 the first week, i returned 11 that same week.
