I've had my EVO since launch and until this last week it has worked great. From time to time, not consistently, the screen only dims and fails to time out. At night the screen will occasionally turn itself on, dimmed of course, and drain the battery (this happens both while charging and while unplugged). After the first couple times I turned the phone off, briefly removed the battery, and turned it back on again. This worked for a day or two, but the problem persists. When the power button is pressed the screen turns off. Swype installer is not running. I use Launcher Pro Plus, Screen Suite Lockscreen (uninstalled, no change), and Juice Defender (uninstalled, no change). It only happens at home when connected to WiFi. The latest downloaded apps were mini squadron and last call widget. Facebook, among others, recently did an update.
