For about 3 weeks not my HTC Hero (sprint) will not vibrate at all. So far, I have tried: Wiping the phone and after I did it I tried to see if it will even vibrate on key press while I have that setting selected and no. Still will not vibrate I am using Handcent as my message app, and uninstalled it to see if that was the problem and no it wasnt either. Of course I have checked my settings and it is set to vibrate. After that I started installing almost every app in the android market that says vibrate in the title. Nothing at all that I have tried has worked yet. Has anyone had this problem?
