alt Hacker NewsMy Android phone has this too (Vivo). Maybe they all do?
It wasn't well explained what it was for though, I discovered it while messing with the settings and thought it was just a cool random feature to visualize motion. I'm just now learning it's for motion sickness.
Honor phones have this in the quick settings (the thing that opens when you slide the right side of the top bar down), labeled "Motion Sickness". Felt well-explained and discoverable.
But the beauty and pain of Android is every brand having slightly different UI. This might well be a manufacturer-specific feature. Or maybe it's a common Android thing that some brands just expose better than others
