I just noticed my phone running the boot animation while it was sitting on my desk, which is weird because I had the phone on. Now, its doing a few odd things, it seems to have wiped some of my settings, like it erased swype, it is no longer displaying the lock screen when I hit the power button, and the home and search keys aren't working. Also, when I hold the power button, only "turn off phone" comes up, none of the other options. My phone isn't rooted, so what could have done this?
