Hi ! 

For my application, i need to detect when the headset is unmount and mount. 

I used a lot of solutions but none work. The only solution who worked on Quest3, doesn't work on Quest3S. 

I used OVRManager.HDMUnmounted but it only work when the headset is on veil on the Quest3S and not when is off the head. That kinda weird. 

If someone have a solution.

Thank you

While this thread is old I ran into the same problem and found the cause.

The Meta Quest 3S does not have a proximity sensor, unlike the other headsets. Because of this OVRManager.HMDUnmounted never gets called (or perhaps it does but only after the headset has already gone to sleep).

To solve this I used the OVRManager.OnInputFocusAcquired instead for when the headset comes out of sleep.
