YouTube is experimenting with a new lock screen feature for Premium users

YouTube is currently testing a new feature that allows users to lock their screens to avoid accidentally tapping a button and disrupting the video.
“Lock Screen” disables touch input, so when users watch a video in full-screen mode, they don’t have to worry about unintentionally pausing, skipping or selecting a suggested video. Users that have access to the test can tap on the gear icon in the top left corner of the screen to turn on the feature.
As reported by Cord Cutters News, which first spotted the new lock feature, it’s only available for select Premium subscribers on Android and iOS dev
