NatDevice - Media Device API

Thank you for releasing the latest version of NatCam (2.2.1).
The known Android platform bug seems to be revised definitely as far as I tried it.

However, I have encountered another problem.
The latest version of NatCam (2.2.1) seems to have the same problem as Unity’s WebCamTexture API.
This is a problem of the low illumination of a front camera occurring only with some Android devices.

This problem was not present in previous versions.

I am in trouble as I have been using NatCam as an alternative to this problem.
