Hello ElnesPe,
We understand that your camera is not working as expected after completing the latest software update. We'd like to provide you with a few steps that can may be able to help:
1. Clean the front and back camera lenses with a microfiber cloth. Verify if there is any dirt or debris inside the lens or if the camera lens is misaligned or blocked.
2. Restart your iPhone.
3. Test the camera again by taking a photo. Verify if this issue occurs with the front and rear camera. To switch cameras, tap the rotate button.
If the issue persists, your device may be experiencing a hardware issue. In that case, we suggest that you have your device evaluated by a certified Apple technician. You can follow this link for further direction on how to schedule an appointment:
