The other day I was sending a text message on my phone and after I exited out of Handcent, my home screen was completely black. I thought this might be a fluke so I powered it off and back on and it still came up black. The lock screen will show, but when I unlock the screen, it was showing nothing but black. I was using Lock 2.0 for lock screen and helix for my home. Finally, we were able to get it back working, but I can't for the life of me tell you what we did to get it working again. Has this happened to anyone else? Anyone know what could have caused it and how to prevent it in the future?
