I had the note 2 before, and I have to say that the 2 typical hardware problems remained:
Camera is crap on low light
low wifi and hsdpa signal
I think thats really sad on a phone like that.... if i want to make pictures at a party with barely light, i sometimes wish my old iphone 4 back
with iOS you can't do so much, but the things you can do, you can do in perfection.... who needs 12MP on a blurry picture?
it's really not that difficult to look for a camera modul that is appropriate to a 800$ phone, instead of developing more and more additional funtions that no one uses until it's a complete sw-chaos
