Reddit users thevincentasteroid and MMD3_ posted about an auto-playing video ad (with sound) on the home screen. The ad is for Chicken Tender Wraps from Carl’s Jr. When it begins auto-playing, it pushes all the other UI elements out of focus and goes almost full-screen, returning to the home screen after it has played through once.
Yeah, that is why I find it amazing that it works for some apps.
Honestly, I’m surprised it works too, especially for apps like the launcher. I guess we can thank the engineers for taking the easy route
