Weird widget suddenly appeared

[lizzy64]

This popped up on the right side of my friends Galaxy S21 ultra. We can't clear it away and it doesn't do anything when you press on it. It appears to be a widget, but for what?

@lizzy64 It looks like the Color correction button from the Accessibility settings. To turn off the Accessibility button:

1. Open phone settings
2. Click on Accessibility
3. Click on Advanced settings
4. Click on Accessibility button.
5. Click on Select actions and select "None"

Actually, in my settings it goes like this:

Accessibility/color correction - slide off (or on) color correction shortcut.

So, whichever works.

That's a sword, one can't simply pull Excalibur from the stone. One must be worthy enough to use it.

It looks like it might be a button for the S-pen. If you tap it, is there a settings option where you can turn it off?

I don't have an Ultra or an S-pen myself, so I'm going by screenshots I've seen in other people's posts.
