I have my phone set to turn the screen off after 15 seconds of being idle (the lowest amount of time my phone allows), but that still seems to be too long, as far too often, I've tossed it back into my pocket, only to find out later that, while in my pocket, an app or two has been opened by brushing up against my leg before the screen turned off. So, it's getting kind of annoying. It'd be nice if there was like a widget, or something, that I could just place on my main screen, and press it to immediately turn off the screen when I'm done using the phone for the time being.
