Weird startup shutdown behavior.

I've had my phone for about 6 weeks. A few weeks after I got it, it started acting weird.

Occasionally on shutdown, it will end with the AT&T logo, instead of the just a blue ball. Other times, it shuts down normally.

About a week after that, the startup screen would appear all scrambled every time I turned on the phone. The only way to get beyond this, is to tap the power button, then everything proceeds as normal.

Anyone else experienced this?

That definitely looks weird. I had my phone restart on its own one or twice due to an app crashing but never seen this screen.
