Go to Settings. Select System Apps. Tap on Camera. Then toggle to enable Scan QR codes.
You can scan QR codes on an Android device using the default camera app or the Google Lens app. As long as your Android device has a camera, it should be able to scan any QR code. Once you've scanned a QR code on your Android, you can open the URL or share it.

Thanks in advance!
