I bought this phone in may 2015 and using it till then. the main lag of the phone is flash iS not provided otherwise camera quality is good in daylight and quite decent front facing camera in this range of phone, so if you are looking for budget phone then it is good, but one more problem I faced was forced 3G mode.
This phone does not have forced 3g mode but this also gets solved after using some tricks in phone testing mode.
