I am reviewing this device on basis of my 2 week experience. its design is same as most of samsung’s devices, repetitive. camera quality is good in daylight but just average in artificial lightning. battery light is great, you can easily get 1 day of battery life in 1 day of usage. call quality is good volume is not that loud. display quality is awesome, thanks to super amoled screen. performance wise, its just ok, not good for gaming. in daily use, I noticed lag many times. it has 8 gb internal storage which can be further expanded via sd card. I will not suggest this phone as there are better alternatives available at this price. thank you.
