We rely on the device to tell us the device has multiple cameras, but sometimes devices don’t do this, even when they have multiple cameras. What is the device model? Setting the device default camera to the back camera should make the Tulip default the back camera.
Actually, i’m allowed to change camera with the barcode scanner and this testing gave me the solution to my problem : the widget was not big enough to see the all the buttons as the switching option is in third position, i thought it was normal to have only two. Change my display and it’s solved ! Thank you
