I find no way to keep the screen from turning off when on USB power. The feature is available on other phones but not on my Strat as far as I can find out. The guy at the Verizon store had the ability to set that in his android Power Settings menu but not in my Strat. Anyone know how to do that? I hate it when the screen turns off suddenly when using the phone as a GPS and it is plugged into the USB!
