Help No Auto Dim Option

[bcherry]

I am trying to turn auto dim on/off to save battery life and i cannot find the option to do so. I went into settings>Sounds Display> and all i see is a "Brightness" option that adjusts out bright the screen is, without a "check box" for Auto Dim...

Any help would be appreciated.

Thanks.

Thank you, I had a feeling it would be something simple.
