There is a definite difference. They are not super sharp though. I think I was expecting too much from the update. I think there are still much better camera phones out there such as the 1020, Xperia Z IMO, and the Optimus G Pro.
I just bought a jused 920 specifically because of this update. I'm on the fence now as to whether or not I should keep it. I was hoping to "get by" until the1020 prices came down a bit. I may wait for that, or I may just pick up a phone with a better camera right now. Maybe the Iphone 5c ?
