I have been using xolo era 4k since last 10 months. overall i’m telling you its good but not in the price range of 6400/-rs beause its main function is camera which is okey, display is all right because its giving one function like MIRA VISION by adjusting this you will be get very good quallity of display and colour after that come to sound and its reception, sound you can say very loud and clear and its microphone also a good quallity with noice cancellation also guys you can see it from the picture that in design there is no compromise you will get well finished design which is very comfortable and easy to use, what can I say about durabillity my gorilla glass had broken when I was using it I dont think so that its very good in durabillity. but compared to the smartphone you can say that it is much strong than other. future is also great in this mobile but I harassed due to there is no software upgrade . it comes with lolipop 5.0 and u are bound to run with this version. and I have above said that feature is good but compared to price I will suggest that price is much high .
