I have UD 8.0 w/ watermark'd theme and when i wake the phone up after it has been sleeping for a while about half the time it will have some serious lag when switching screens or trying to do anything basically. if the screen is off for a short period of time the phone is really snappy and works fine, only have issues when its off for more than about 10 min. i have tried about 6 different kernels of Chevy's to no avail. Anybody have any suggestions??
