This is a nice mobile it is a value for money device. Sounds is lower but its manageable. It hv hybrid card slot. No fast charging. Phone gets extrem heat while charging. Xiaomi provide very poor service to their user its a major problem for buying this phone. Except all of this the mobile is allmost good with 9999/- for 16gb. If u want use single sim with memory card other than go for 3gb ram+ 32gb rom ?
