Doesn't the app BB light fix or solve some of these problems by overiding the back light controls and giving you more options? I have used that on every BB I have had, and set it turn the back light on for any user activity, removal from holster, etc. And it seems to solve at least some of the problems with the back light and it's lack of controls.
