The Android port source engine cannot adjust the gamma value in the options

[magisk666]

The menu option to adjust the gamma value in the source game is disabled. Can you turn it on again? This function is suspected to be available.

It is disabled because Source changes brightness by adjusting the monitor's gamma ramp directly which Android does not allow.
