Best and powerfull phone at this budget. Display quality is very good.very sharp. Supported most of games. My freind plays god of war via psp emulator.
With some adjuset setting he can play god of war in high fps.
Phone is upgradable to lollipop.
But it have only 5 MP camera. Front 2 MP camera. And phone is not slim phone is heavy . and battery is having only 2000 mAh only. Now a days user needs minimum 3000 mAh of battery.
But over all new phone micromax canvas spark is new micromax budget phone.
