Lock the screen when video is playing

[Mtm1401]

When a full screen video is playing, an option to lock the screen (whilst still playing the video) would be useful, to stop accidental touches etc.

For example I have a small child who sometimes watches YouTube videos, but will touch the screen and close the video, and I want to be able to lock the video to keep it playing until I unlock it with a certain action (maybe holding the power button down or something similar)

I'll pass your suggestion on to the developers 😉.
