and it was kind of laggy. I used ATK which helped slightly, but it seemed to not be as responsive as the EVO I had (that I can remember), and definitely not as quick as the I4. I even did a reset on it, and it made no difference. I noticed it when browsing the web the most; going between apps seemed fine. Now, this AT&T store I tried it as is insanely busy, and they have already sold a ton of them. Maybe someone played with the demo and downloaded something that is taking lots of memory, but I didn't see it. Has anyone else noticed this? Maybe a faulty unit? Or is it just because of Samsung's UI??
