android15 修改默认亮度及关闭自动亮度调节

默认亮度
1、先把设备亮度手动调整到对应亮度
2、通过adb命令获取对应亮度值

adb shell settings get system screen_brightness 

3、代码上修改默认亮度值
SYS/frameworks/base/core/res/res/values/config.xml

-    <integer name="config_screenBrightnessSettingDefault">102</integer>
+    <integer name="config_screenBrightnessSettingDefault">255</integer>

SYS/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

     <!-- Default screen brightness, from 0 to 255.  102 is 40%. -->
-    <integer name="def_screen_brightness">102</integer>
+    <integer name="def_screen_brightness">255</integer>

默认关闭自动亮度调节
VND/vendor/sprd/res_overlay/SettingsProviderOverlay/res/values/defaults.xml

     <bool name="def_bluetooth_on">false</bool>
 
     <!-- Default screen brightness, from 0 to 255.  102 is 40%. -->
-    <bool name="def_screen_brightness_automatic_mode">true</bool>
+    <bool name="def_screen_brightness_automatic_mode">false</bool>
