Hi, i'm the very pleased owner of a HTC Desire. I've noticed a couple of problems with it recently, even before the 2.2 update. It appears to have a problem with the + and - buttons on the side. Say for instance i am watching a video, i can increase the volume, but i'm unable to turn it down. Has anyone else come across this problem? Also i was using the camera this morning and noticed that half of my screen turned to purple!!??!
