TikTok has been experimenting with an auto-scrolling mechanic for months now, allowing you to watch TikTok hands-free.
To use the auto-scroll feature, long-press a video on TikTok's For You page, similar to if you want to repost a video, and click the auto-scroll button. Your feed will now cycle through videos independently without you having to lift a finger. However, if you get to a photo post, scrolling will stop until you go through all the photos.
To turn off the feature, long-press your phone's screen again and select “Manual scrolling.”
Since auto-scrolling is still being tested, the feature is only available to a select number of TikTok users. TikTok auto scroll has been highly requested among users, with many looking for tricks online to make your daily TikTok viewing experience more efficient. For example, you can go to your iPhone's settings, turn on voice control, and create a command that will swipe up on the screen when you say a phrase of your choice.
The capability follows in the footsteps of YouTube, which tested an autoplay feature in 2014.
