Things I've noticed....bad 1. The blue edging...SUX and hangs, the bounce was better 2. One of the sensor calibrations is missing now 3. "The Worst" now my gs2 will not go out of edge service... disappointing 4. Typing/touch cursor now has problems A fix is definitely needed now...or a way to remove the update...
This issue is thanks to Apple patenting the "bounce" - nobody is allowed to do that bouncing other than Apple (barring licensing fees paid, assuming Apple is willing to license that idea). I can't blame Samsung for that.
I didn't notice the sensor missing
I don't not have 4G anywhere in my local area, so I can't tell what's going on with that.
I've noticed that Swype seems better than it was before. It seems to pick up my swyping with a little bit more accuracy with this update.
