Thx for sending the details. Could you please send us a video showing the initalization process, so we can see the movement of the phone and also the surrounding used for the initalization?
Please make sure to move the device sideways, back- and forwards during the initialization phase.
Thx and greetings
Tryed to run on my Samsung galaxy J5, and it does'nt detect the plane.
