Document

The amount of gain applied to sensor data before processing.

The sensitivity is the standard ISO sensitivity value, as defined in ISO 12232:2006.

The sensitivity must be within CameraCharacteristics#SENSOR_INFO_SENSITIVITY_RANGE android.sensor.info.sensitivityRange , and if if it less than CameraCharacteristics#SENSOR_MAX_ANALOG_SENSITIVITY android.sensor.maxAnalogSensitivity , the camera device is guaranteed to use only analog amplification for applying the gain.

If the camera device cannot apply the exact sensitivity requested, it will reduce the gain to the nearest supported value.
