      I cannot see the camera preview on the smartphone's screen

      If the camera preview is not displayed on your smartphone’s screen, follow these steps to resolve the issue:

      1. Check cable connections

      • Verify that all cables are connected in the correct order and securely plugged into their respective connectors.
      • If the problem persists, proceed to the next step.

      2. Start devices separately

      • The issue can occur if devices are started while already connected.
      • Ensure that the smartphone and smart glasses are started separately before connecting the cables.
      • Once both devices are powered on, connect the cables to the smart glasses and smartphone.
      • If this does not resolve the issue, move to the next step.

      3. Test for defective cables

      • A defective cable can cause the preview to fail.
      • Test using a different OTG cable or USB-to-micro USB cable to determine if the issue is with the cable.
      • If the preview still doesn’t appear, proceed to the next step.

      4. Disable standalone mode

      • External cameras or glasses may not be detected in standalone mode. To work around this:
        1. Turn off all devices.
        2. Disconnect all cables.
        3. Turn on the smartphone only and log in to XpertEye.
        4. Connect the glasses or external camera to the phone.
        5. The camera preview screen should now display.
