Battery was awesome , Not hang like same as other mobiles , freely I like the camera, it was just amazing.Keyboard has some new function to type Farley and fast.
Speaker is very powerful but I think headphone want some more improvement.Its charger is of new type, we can connect two cable in one adapter at a time there are two slot in adapter to use charger.
And finally it was a good phone for new generation.
And yes it support 4g.
