One thing I've noticed is, originally it started out with my front camera on my samsung note 9 which was a pain and wasn't working well but then somehow it changed to the back camera. I am not sure if there is a way to add a setting that would set the camera preference?
But now it is back to selecting the front camera on my Note 9, Also on my Galaxy Tab Active 2 it starts at the front camera and then locks up the camera.
(Hi Richard I know this doesn't help answer you question but I just wanted to add that I am having the same problem)
Hi Vitor , I'm running an app on an Samsung Galaxy Note 10. I have left the camera parameter to 'back' but it seems to only use the front camera so its getting my face and not the QR code I am pointing at. I also tried to change the camera parameter to 'front' just in case it worked the opposite way. however that didn't work either.(I am guessing as there are 3 cameras on the back the code cannot figure out which back camera to use and defaults to the front camera) . I would be helpful it you can help me fix this issue. Thanks.
