2 camera detected in front where there is only one and 3 detected back for 4

[bphd]

It's a legit phone (SamSung) so with real cameras and I know that some cameras are only to get informations and not really to take pictures, but for now the application detects one more camera in front and one less in back. It wouldn't be problematic if it wasn't avoiding using 64mpx mode and staying at 16mpx maximum instead...
