I cannot see the camera preview on the smartphone screen

Resolution
1The most frequent cause of this problem relates to the order of the cables and the device startup sequence



Check that the cables have been connected in the correct order and that each cable is correctly plugged into the related connector.  

If this does not fix the problem, move on to the next step.

2The problem occurs when devices have been started with all of the cables connected between them.
Check that the telephone and glasses were started separately.

Then connect the cables on the glasses and dedicated device side.

If this does not fix the problem, move on to the next step.
3This problem occurs when one of the cables has a defect.
If you have any other OTG cables or USB-to-micro USB cables, test them separately.

If this does not fix the problem, move on to the next step.

4Sometimes, glasses or external cameras may not be detected when standalone mode is enabled
To work around this problem, perform the following steps:
Turn off all devices  
Disconnect all cables  
Turn on the phone only  
On the phone, log in to XpertEye
 Connect the glasses or cameras
 The preview screen should be displayed  
 If this does not fix the problem, move on to the next step.
