First the display is big and awesome, the touch is even better than other samsung phones and can be comparable to samsung s6 and far better than micromax and etc.
I bought the phone 2 months ago and it got fell down 3 times since then but it is working as good as new.
The 3000mah battery is really awesome no heating issue at all, playing asphalt 8 for 2 hrs and it gives me 24 hr full backup on single charge, yes I used it for 24 hrs( Day+ Night) on single charge while on a vacation. Dont worry about the 1.5 gb ram trust me it works better than micromax phone having 2 gb ram. My phone never hang at all although i’m a heavy gamer playing asphalt8 all day. And the camera is just awesome both the front and rear.
