So far the only major complaint I have with 2.2 is that it's slower for certain things. Scrolling through pictures in the camera app is slower. With 2.1 the pictures would show up immediately even when scrolling through them very fast. Also the grid view would load much faster, now i see a blank gray picture for 3-5 seconds before the actual photo loads. Scrolling through my contact list and app list is slower and choppy. Before it was fast and smooth.
Has anyone else noticed these types of issues? Could the amount of processes running in the background cause the "jitter" during processor intensive usage? With 2.1 I had the bare minimum running in background - maybe 2 - 4 processes and never had any issues. Now, I've disabled ATK - which seemed to help battery life, because of the wonderful programs that auto-restart themselves (such as Amazon MP3, footprints, skype, VZ Navigator, FM Radio, etc...), and have 10-20 processes at most times.
