This is a nice mobile it is a value for money device.sound is lower but its manageable. It hv hybrid card slot. No fast charging.phone get extrem heat while charging.xiaomi provide very poor service to their user its a majoi problem for buying this phone.except all of the mobile is allmost good with 9999/- for 16gb.if u want use single sim with memory card other then go for 3gb + 32gb rom? Which is very aggressive when you consider the overall package I have been using this device about a month or so and it is a value for money device.
