Sorry for the long title. I tested this several times after noticing it. I will set my phone to the home screen and let it time out. Afte a few more minutes to ensure that the data manager has stopped all apps, etc, I'll push the button to turn the phone back on. When I unlock the screen, I am at some random screen, not the home screen. It may be the contacts, battery information screen, or some other screen. Would could cause this, it used to always open on the home screen. I'm sure it might be hard to diagnose, but any ideas that might cause this would give me somewhere to start.
