I have used the Pin option, pattern option, and no unlock code at all on my Droid, just as background to my question. I like the first two I mentioned, but I want to quickly disable the lock screen when I drive. I mount my phone on a bracket and have it hooked into my car charger and a headphone cable hooked into my stereo for Pandora, calls, etc. I certainly don't play with my phone while driving, text, or even hold it. The reason why I want this is if I am using Pandora (autolock off so the screen stays on) and I get a call, the screen will be off after the call ends, and needs unlocking again. I don't like having to unlock it with anything other than a quick swipe to the right while driving that I don't even need to look at. Is there any way to quickly disable or enable a screen lock without going through all the settings?
