I have wind 4 ,
It’s snapdragon processor , dts sound quality , True 4G , nice squre look & smart camera position also 4000 mah battery for longer useing ,
Warming some times , ( in my handset - screen sleeps anytime after 1 month use) , it has no gyrometer which can used in Playing games like POKEMON GO ( The real - point for gaming lovers) for. AR mode.So, now I using it but with some hassles also, atleast JIO can make yours mind to buy it.
