I want to tell you , that this phone does not work propely according to specification. The sim contacts are not showing, also there is no external devices like headphones is giving with it. The camera quality is also poor , front flash is not in it. Hard to use , it has its own apps , which are taking more memory, also the micro sd card cannot use with the dual sim the . You need to use a single sim with sd card, if you use dual sim at a time than you cannot use sd card at the same tume , these are major problem of this phone
