More functional device locking

[pyro546]

I found that whenever I bent at the hip that my pants were pressing on the buttons on the phone and causing it to (in my case) want to shut down. (if you store your phone in the opposite position it could be pressing on the "voice dial" button in the same manner) My fix was to put a poece of electrical tape over the buttons and then use an exacto knife to cut around the buttons and remove the tape over the buttons. This results in the buttons not sticking out so far and therefore less problems accidentally pressing them. It's not a fancy software fix but it works.
