Phone is good evry app running smoothly no any hanging , but when talk about connectivity it lost the signals easily very disappointing. This is an average phone in this budget. I was using Mi4i before it and found Mi4i is superior in most of the cases. the disappointing the camera. it picture is always having some radish colour. the GPS capability also doubtful, it lost the connection very often. other phone do not have the same problem. the phone is doing perfect with VOLT. the sound system is good. But not Upto mark.
