Occasionally the phone's screen will turn white. What I've noticed as that it typically happens after the phone shuts itself off. I don't know how it turns off, and it doesn't happen often, but occasionally I'll pull my phone out of my pocket and find that it's completely off. When I turn it back on it will boot all the way to the home screen without issues and then the screen will fade to white and stay that way. Pulling the battery does not fix the issue. All it does is kill the battery more than having the screen being all white and full power. Most recently it happened while I was navigating the Store in the Amazon Kindle program. Looking around I've seen conversations stating that the screen's going bad (which I doubt), the OS needs to be reinstalled (which I attempted through the Desktop Manager and I think I did it how I'm supposed to without wiping it with a 3rd party program), or that the phone is defective. My dad got the phone in November of 2008, and I got it when he decided to get an iPhone.
