My camera not work at normal zoom 1x but working at zoom 2x

Hello katreen225.

Welcome to Apple Support Communities. I understand that your camera isn’t working as expected. I’m happy to help.

If you haven't already, I recommend to make sure that your iPhone is up to date: Update your iPhone, iPad, or iPod touch

If you're still having trouble with the camera opening to a black screen after updating, then you'll want to contact Apple Support for further assistance.

Take care.
