HTC Sensation — Changes Skins and Backgrounds at Random

I am having a very ODD problem with my Sensation. It seems as if every time I plug it in to my computer it changes its background to the stock Sense 3.0 background. Also, one time when I plugged my headphones in, it actually changed my wallpaper as well. This is odd. I've also had apps randomly deleted. What is wrong with Sense 3.0??

It also has major problems with the phone locator function.

I've been having problems with Sense 3.0 ever since I bought the damn thing. One time I tried to load a movie and the sound went off and then didn't come back on for another day and a half!

I also sometimes notice a slight delay in my Sensation attempting to register my touch. Strange thing with the wallpapers tho. It didn't actually delete the wallpaper, though, right?

Actually, it did delete my wallpaper! I just noticed this when going back to replace it. I used to have anipets aquarium wallpaper and now it's gone! WTF.

That is super lame!! I wonder if it's maybe a problem with the wallpaper you downloaded?
