After update to IOS 13, appear a circle with a dot in the centre of the screen

I have managed to remove it. Go to Assistive Touch through the setting. Go to the “Mouse Keys” and disable it.

I'm thinking you have something enabled in Settings > Accessibility

What exactly it is, may be new, so I'm not sure. But I'd check your Accessibility settings to see if you've got something on you didn't have on previously.

Guess it detects it as a bluetooth mouse i guess . Or u may try to get a bluetooth mouse to connect to ur phone . If its appear and able to use , then its the features of mouse support . Hope apple will add on a on off toggle for iphone users .

Guysss, I figured out, if you turn off your bluetooth, the circle will disappear. And if you turn back on then the circle come back.

I had this too . Are u connecting to any of audio bluetooth (example : car audio bluetooth) ? Cause i had checked ios 13 had a features for mouse support . Guess that when we connect to car audio bluetooth , it detect as as mouse and the dot appeared . Guess that dont have a toggle off instead of turning off the accesivetouch .

Yeap. But we all need that assistive touch. Lol

Same here... I think it’s a mouse pointer... I wish they have on/off switch for this. For the meantime, i just reduced its size and set it to auto-hide just a second..

Hi! Already tried turning off the Mouse Keys on my iPhone 7 Plus and it still appears, especially if you change the view from portrait to full screen. I have taken this picture below using my iPad Air 2 because the dot disappears every time i use screenshot.

That's not it. iOS 13 does NOT have mouse support. iPadOS 13 for iPad will.

Looks like a HomePod icon.

So this function on iphone is useless ? As i search , there is this function available and the icon on the middle of the screen like chong posted .

How do you resize and auto hide?
