So more differences are in the camera app, like the shutter button has changed a bit, along with the flash toggles now show up as 3 different buttons in one grid rather than having to hit the flash button until you get the one you want. also scrolling through home screens is greatly improved, along with my battery now lasting ALL day. I have the extended battery and usually from 7:30am - 11:30 pm ill have about 30% remaining. so thats a very welcome update.
