I had just finished adding movies to my watched list in my IMDB.com app. I then exited, which involved pressing the back button several times because I had added so many movies. After this, I checked my email, read that and exited. It was then I noticed that my wallpaper had been removed and replaced by the gray one with the ones and zeros. I went into my gallery and reset the wallpaper. I then opened my phone's keyboard to reorient to landscape mode and as soon as I did this, my wallpaper disappeared yet again. I touched the gallery yet again and then all hell broke loose. The dialer came up, then the phone's native browser. I backed out of those and they immediately launched again on their own. Finally, I had to reboot. What could possibly cause such crazy behavior from a normally mild mannered phone?
