its main problem is of sound system. the music clearence in not much good. the sound is of poor quality and the speakers used in the mibile due to which the speakers sound comes like it has been burst the speakers.
second problem is that if its has hybrid slots due to one cannot use two sims and memory card one can use only one sim and one memory card or two sim or one sim one memory card at a time.
