Only front camera is available on android phone... no parameters available to solve this

Hi. I'm using this plugin and like the previous comment has said, the back camera is never available. I've been through the code and fixed some issues and now it works. But I would advidse you to recheck the code and look specificity at the part where you check if the device is iphone or android. The logic needs a small improvment. 

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.
