Don't use "Dimmer" app
 

I downloaded the app "Dimmer" which is designed to make the backlight even dimmer than what Android will normally allow (for night usage, in the movies, etc). Tried it and my backlight went completely off, and I couldn't find anyway to disable that (obviously, as I couldn't see anything). I did a battery pull and that restored the backlight.

Just thought I might save others a little aggravation.

Actually, once booted and all the background processes loaded it went dark again. I had to go into the settings just after boot but before the Dimmer service started and set the backlight to Auto.

I don't have any problems with Dimmer app. I didn't like that the stock Android doesn't dim the screen enough, Dimmer is nice. I wanted it even more dim, so I am also using an app called Screen Filter. It essentially puts a black filter over the entire screen (always on top), and you can adjust the dimming level. It can get VERY dim!! :D

If Dimmer app is not working for you, try Screen Filter.

I use a b&B backlight controll widget, it doesn't function 100% (ie won't turn backlight below 9% and the dimmest setting is somehow 22% O.o). But this is because of android on our devices not the app. Its still allows for the backlight to be lowered further than android would normally allow to save battery.

I had the complete backlight turnoff incident once, but I knew my android somescreens well and was aple to find the app, click on it and increase the backlight again :D
