Is the Droid particularly susceptible to minor shocks? I have found mine to be particularly sensitive. When dropped to a tabletop from the incredible height of a half inch the screen went black and the phone rebotted. Yesterday while it was resting in the armrest console in my truck I went over a particularly rough set of RR tracks and it did it again. What was most annoying then was that I was using the NAV function to direct me to a job interview and I had to stop and wait for it to restart so I could restore the directions. I have checked the battery and cover. They both seem to have a good, tight fit with no slack or movement. Thoughts?
