I just removed advance task killer and a few other apps that were slowing me down. now, when i hit the back button to go to the home screen the screen turns black with the HTC text like it does at boot up. This happens EVERY time I leave an application. I am rooted at the moment though I have not done anything else other than that. Should I reset this to factory specs? Also the headset jack is not detecting earphones which it was up until today.
