I used this phone for about 4 months. It was awesome. I played many games like asphalt8 air bone, real racing 3, csr racing and many heavy games.
In this all games run smoothly s4 comes with 13 megapixel of rear camera and 2 megapixel of front camera it comes with 2gb ram and full hd screen with pixel density 1280×1080* it comes with corning gorilla glass and the experience of watching full hd videos is mind blowing the phone was lag free though installing heavy games n many useless apps
I would recommend to buy this phone whose budget is under 15k now the price of samsung galaxy s4 is 12999 go for it
