I use the Swype keyboard now because the new Samsung keyboard is bad. I noticed the freezing up and for me it was because it was connected to my facebook account. It was also causing battery drain because of that. I looked one day and a stupid keyboard accounted for 7% of my battery drain which is weird. So I unlinked it with facebook and now there is no lag and Swype is never showing up in my battery log. I tried the swift key flow beta and hated it. Annoying sound on keypress and it wasn't very good with capitilization. Also, the icons and numbers weren't in the traditional locations so it just made it kind of annoying to have to get used to new layouts. The Swype keyboard on my S3 works great even though I would prefer the Samsung keyboard. However, the Samsung keyboard just doesn't work like it should.
