nexus 5x - open front facing camera and display is rotated upside down

[yoas fs]

hi, i tried to implement zxing to read qr code(s).

when i open front facing camera with nexus 5x it rotated upside down, meanwhile it worked perfectly on my other phones (i tried on samsung S7, xiaomi 4i, sony c, nexus 6, even nexus 5 still worked pefectly)

let me know for any update for this issue :)
thanks
