It is the one of the best phone I had.it has very good features.it also supports 4g Volte .but the battery was not good, phone is heated up very fast when we switch on hot spot.some times the device become very slow then we have to restart it.the internal memory 8gb is not sufficient, the memory will fill up very fast.8mp cam is OK.bike mode is there but it not use full.Samsung j5 and j7are better than this.
