In the case of open automatically adjust the brightness, change the parameter is screenAutoBrightnessAdjustment brightness values, the range is 1 to 1, I met a problem, as follows: if you want to be in the case of open automatically adjust the brightness that drag the brightness is invalid, would USE_SCREEN_AUTO_BRIGHTNESS_ADJUSTMENT normally on can be set to false, but the modified has been a constant value and I was not true, at ordinary times is ok, but can't manually change brightness under the glare, this makes me very headache, because this value not been modified in any place
