Why do I have a floating hidden grey button with an X in the corner of my phone

[Android Central Question]

There is a hidden floating grey circle with and X in it in the top left corner of my phone. You cant see it unless you tilt my phone though. I just noticed this after the most recent upgrade yesterday, 10/2/2020.

Welcome to Android Central! Is it on every screen in the same location? If so, that might be screen burn-in.

Can you get a screenshot?

I've added the screen shot I could get

If nothing happens when you tap or long-press it, and if it doesn't show up in a screenshot, chances are it's screen burn-in. If it doesn't show up in a screenshot, then try taking a picture of the screen with another device and share it here.

Does it go away if you change the wallpaper?

Also, see if it goes away in Safe Mode: https://www.t-mobile.com/support/devices/android/samsung-galaxy-s8/safe-mode-samsung-galaxy-s8

A-ha! So you must have made a wallpaper out of a screenshot, which included that icon.
