Device Orientation Issue

Hi Team,

I have a issue when rotating the device . If device is in either LandScape Left/ Right or Portrait/Portrait up Side Down then navigation will be changed according to orientations. But device is either LandScape Left/ Right or Portrait/Portrait up Side Down means (like slight difference in angle of rotation.) . In that case, which direction can take the device either LandScape Left/ Right or Portrait/Portrait up Side Down?

 please find the below image:
