Disable Automatic Backlight Dimming while Charging

[DeMiNe0]

Hey Everyone,

I'm running into an issue, that i'm sure many of you have ran into at some point and found a way around.

When I have my Phone Plugged into the Charger (For example when in my car) after a set amount of time (I think it's around 30 seconds) my screen will Dim to only about 25% brightness(But never shut off completely). As you can imagine, this is horribly inconvenient when I'm running Google maps or sprint navigation.

How can I make it, so that when I'm charging the phone, the screen just always stays on and does not dim at all? And then when i'm on battery the screen resumes the normal behavior of shutting off after 30 seconds.

I've tried setting the "Stay Awake" option under "Applications > Development" to on, I've also tried setting the "Automatic Brightness" option under "Sound & Display > Brightness" to off. Neither of these worked.

The only thing that DOES work, is setting the "Screen Timeout" option under "Sound & Display" to "Never turn Off". But this disables the Automatic Shutoff of the screen even when on battery.

Anyone have a solution for me? My phone is rooted using Toast's method.
