Before (right) and after (left) Princess Butterfingers got her hands on the MediaPad M5 Lite.

It offers the usual parental time limit controls and a dedicated "Kids Corner" interface, but also introduces some novel behavior-focused controls as well. It can detect when the tablet is too close to a face, the ambient light is below a certain threshold or if the tablet's being used at an "unhealthy" angle, such as overhead. It will then pop up a little warning animation in the corner, which expands to the entire screen if not heeded.
