I am using this phone last two weeks. I bought this in local dealer. First I would like to tell issue of this model. Battery is not enough, it sucks. If you connected with internet you should charge it twice a day. Its the big problem in this model.pros: :-) * Good display. sharp and bright. * No lagging (this is very important) - 1.3 GHz Cortex-A7, Quad Core * Preinstalled essential apps * Good outlooking(Very rich). * Very good graphics performance.Cons: :-(((( ...
