YouTube is testing two new features for Premium users on the Android platform: "on-the-go," which provides more accessible controls for users multitasking while watching videos, and "auto-speed," which automatically increases video playback speed to save time while maintaining comprehension. These features are currently being rolled out and have not yet been listed on YouTube's standard features page. Additionally, YouTube is experimenting with a feature called "Previews," which shows users short clips of potential video content based on algorithmic predictions.
