I was at ATT playing with the 830 today, and while performance in general looked fine, I noticed that if I launched a program and then hit Home to go back to the home screen, the animation of the home screen swooping in would consistently stutter. This is only if I'd launched a program (i.e., if I just swiped to the program list and then swiped back, no stutter). Has anyone noticed this? None of the phones were set up on LTE, so I was wondering if it was making a difference.
