2. 把屏幕亮度调到最暗，然后挡住手机感光区，重新调节屏幕亮度，屏幕会完全变黑。

frameworks/base/core/res/res/values/config.xml

    <!-- Minimum allowable screen brightness to use in a very dark room.         This value sets the floor for the darkest possible auto-brightness         adjustment.  It is expected to be somewhat less than the first entry in         config_autoBrightnessLcdBacklightValues so as to allow the user to have         some range of adjustment to dim the screen further than usual in very         dark rooms. The contents of the screen must still be clearly visible         in darkness (although they may not be visible in a bright room). -->    <!-- yueshua 20151117 modify 1 to 5 for PROD104106860 begin-->    <integer name="config_screenBrightnessDark">5</integer>    <!-- yueshua 20151117 modify 1 to 5 for PROD104106860 end-->
