GUYS I was so so so frustrated trying to film this. I need better equipment and a better setup... my phone kept falling and I wasn't in a quiet enough area.. BUT I got all the crap edited out and left what was decent from the video, haha! It doesn't always go as planned but I was determined to get at least a short video out of it
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
