Works with Samsung Galaxy S II's dock (detected as a "USB Type")

Works great when it works. But sometimes you need to re-enable it. Can you fix this ?

Used to work perfectly Sometime in the last year this unsexy but extremely effective app got updated to a nicer looking ui. Unfortunately it doesn't work half as well at it used to. Three stars because I still greatly appreciate it.

Tiny Improvement An excellent progam that does exactly what it promises. However I am the forgetful type and I cant tell you how many times I have killed my battery by leaving it on. There is a setting to autoshutoff when manually putting screen off with power button I know. May I suggest adding an option to also autoshutoff after a user choosen period of time.
