After ios 13.4 update, a weird grey circle appeared on middle of my screen. I was able to remove the annoying circle by using method below:
Go to Settings>Accessibility>Touch>Assistive Touch and turn off dwell control.
iPhone 7, iOS 13
No sir. Its a different one. The assistive touch button can only be placed on the sides of the screen while the annoying grey circle i am referring to is fixed on the middle of the screen and if you touch it nothing happens. Turns out it is the dwell control.
The circle was the assistive touch “button"
