I am using this mobile from past 6 months it was good for 2 months and then the problem was started it was hanging twice for every 5 minutes sound reception is not bad.rear some better.there is no use of front camera .battery 4000 mah is only the advantage of buying this mobile.even while writing this review it was hanged twice.8gb internel memory half of the system is used by system apps so dont waste ur money on buying this
