The battery was a bit s### at first so was the screen, but after 2 weeks it all made sense. the battery adapts to your habbits. the screen also improves, maybe they need running in! lol. now wen i go back to sgs3 the screen just looks too fake like a cartoon or some crazy grafitti. seriously this phone is the nuts and watching movies in the bath is a bonus! 8 cores blah blah blah blah blah
