This is not as good phone as you think. It has the worst camera with on led flash and no front facing camera. It has only 1 gb of RAM which is OK.
It’s internal storage is 4 gb from which you get only 1.8 gb free which is very low. It is the worst phone for gaming. It hangs so much. It’s user interface is quite good. It has OS. KitKat which is upgradable to lollipop. It has 1 ghz single core processor which is bad for multitasking.
