Apk unity : no headset


I tried to install an apk in a Focus 3 headset, the installation worked but I didn't obtain head motions (scene fixed on a point and moved with head) and controllers didn't work also.

You'll find the export parameters here.

Could you please help me ?

Thanks in advance for your return.

NB :
- in unity, playing VR worked well ; no head motions and no acces to controllers occured only with the apk directly launched with headset)

- Installed packages are here.
- Player configuration here.


I add also here the Android studio configuration.

If my post is not clear or informations miss, I can send more informations.

Thanks for returns.
