My dad is using this mobile since last 43 days and know it performs very well on basic daily usage but on some heavy gaming it shows some lags but its ok it is not that noticeable.but the low light performance of this phone camera shots is not that great as morning pictures as we know samsung is trying very hard to improve their device to next level.so this mobile can get a software update this month and this can improve the camera and the gaming performance of the phone overall this a great mid range device to have.
