You should go for Samsung Galaxy S4. It comes with 5 inches (Large) display,13 MP Primary camera and 2600 mAh, Li-ion. The smartphone with Great features available at 91mobiles.com. Just Go for it.
If you could raise your budget a little to 18000 then u can go for note 3 neo or galaxy s 4 or if you can't raise it then you could go for Motorola turbo.
Please dont even think to buy Grand 2...i have used it...it lags too much, hangs anytime. You have many choices.. 1. Sony xperia ZR...now its around 16-17K 2. htc 816....specs are good but plastic looks...search around their are better options
