There is an aperture for iphonexs flash photography

That is a setting problem.

Small circles can be set. Please see the following tips for the method steps:

1. Open the phone, enter the main interface, and find the gear-shaped "Settings" icon. This is used to control all functional options in the phone.

2. Enter the settings option, you can select the operator, network, call mode, etc., and the icon that controls the small circle is located in the "General" option.

3. After entering General, there are relatively few options, and the functions we usually use are relatively simple. Select "Accessibility" in the "General" option.

4. After entering the accessibility function, we found the option to control the small circle on the desktop. The professional English term is called "assistive touch", which translates to contact assistant and click to enter.

5. After entering, you can choose to turn it on or off, so that you can control the small circle according to your preferences at different times.
