iPhone 12 Pro Max front camera mirroring doesn’t work

Hi melita19,

Does the front camera work when not screen mirroring?

Restarting can help:

"How to restart your iPhone X, 11, 12, 13, or later

1. Press and hold either volume button and the side button until the power-off slider appears.
2. 
3. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
4. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.

Also, make sure that the latest iOS is installed:
