Does anyone know if the Shield has access to Android's night mode for filtering blue light?  As a lesser option I take it that the twilight app can be installed?

Can the Shield be rooted in order to install f.lux?  I'm guessing that rooting would mess with access to HD Prime/Netflix though.

 I just tried the Twilight app. It seems to be working fine.

Thanks, that’s good to know. The argument for rooted f.lux or lumens over Twilight is that they modify the colours algorithically rather than applying a red filter on top of everything as Twilight apparently does. This means that blacks remain black with the rooted apps but are tinted red by Twilight.
