A real pity did Samsung put all its efforts to silly, useless gesture and view air effect and no consideration to the audio quality, one of the main feature of its direct competitor, the iPhone. The audio capability is unfortunately not a software problem but hardware related. The audio processor is more than miserable. We are back to pre walkman ages. The sound has no presence and results to be extremely flat, FX effects are worsening the situation. The device has a good camera and video capabilities. Very good screen. For all that at least 2 stars. I want to sell the mobile as soon as possible.
