keypad back light

[Guest adub23]

I remember on my SDA that whenever I would open up anything that is open for text, the backlight to the keypad would turn on so that I could see what I was typing. This however doesn't happen with the Juno and I have to press a key to get the keypad to light up so that I can see what I'm typing. Is there any registry hack or anything that will make it so everytime I go into compose a test message or am asked to input some text somewhere, the backlight to the keypad will light up? I'm not sure if the Juno has a light sensor like my SDA so that could also be a factor too.
