How do you get that circle out of the Apple phone?

1. The following figure we take Apple 5s as an example, we click on the phone "settings"-"general" as shown in the picture.

2. In the Open interface, we found the "accessibility" inside the generic to click into, as shown in the figure.

3. In the Open auxiliary settings you will see a "Assistivetouch" we click on it to enter.

4. Okay, now we're in the Assistivetouch interface. We click on the right button to open it so you will find that the Apple phone screen is out of circle effect.

Well this circle has the name of their full names do Assistivetouch, next time don't call Circle Oh.
