[Q] Any way to disable button backlights when using an e-reader?
Does anyone know if there is a particular e-reader app, or any kind of hack, that will allow the S4 to turn off the capacitive button backlights while reading, but leave them on the rest of the time? (I realize I could turn them off entirely, which is what I normally have to do.) This worked fine for me with Cool Reader on my S3, but the "Turn off key backlight" setting doesn't work on my S4, and it is a real annoyance to have the buttons light up each time you turn the page, especially when reading in the dark. I'm assuming this is related to the S4 itself, since I've tried a bunch of different e-reader apps (FBReader, Moon+ Reader, etc), and can't find any that this will work with. Is there any way to get it to function like the S3 did with regard to the button lights?
