Every night around 9ish my phone lags down badly. My live wallpaper stops working and re-selecting it doesn't work. My app drawer will take a few seconds to open, sometimes my home screen apps disappear and all the apps are slow to launch and work on. I had Advanced Task Killer, then tried the Froyo version and after much searching, uninstalled them to let the OS do it's own policing. If I reboot the phone, it usually fixes it. Anyone else having this problem, and if so how do you fix it.
