Two Vertical White Lines

[userAJZMlcDlA7]

Hello,

I have two Vertical white lines at the edge of my screen and when I click/touch it, there is the back/previous action attached to it. Its very annoying and appeared today. Is there any way to remove or disable this feature?

@userAJZMlcDlA7  Just wondering do you have one hand operation + enabled if so you can toggle it off in the drop down menu

This is something from the setting, turn it off. I think it's from edge screen
