Trying to figure out how to keep the phone from locking when it's on the charger. I used to have "keep screen alive" checked in the Applications section of Gingerbread, but this no longer appears to be there in ICS. I'd rather not leave the screen on if I can help it anyway, to prevent burn-in. I just want to keep the phone from locking constantly when I'm listening to Pandora in the truck or using it at home on the couch. Is there a setting I'm missing or an app I can grab?
