## 显示方向配置

**默认配置显示方向**

修改 SF\_PRIMARY\_DISPLAY\_ORIENTATION 配置，配置旋转度数为0/90/180/270

```
(SDK)$ vim device/rockchip/rk3576/BoardConfig.mk
# For Surface Flinger Rotation
SF_PRIMARY_DISPLAY_ORIENTATION ?= 0
SF_PRIMARY_DISPLAY_ORIENTATION ?= 90
SF_PRIMARY_DISPLAY_ORIENTATION ?= 180
SF_PRIMARY_DISPLAY_ORIENTATION ?= 270
```

**ADB配置显示方向**

```
// 0°
(ADB)$ adb shell settings put system user_rotation 0
// 90°
(ADB)$ adb shell settings put system user_rotation 1
// 180°
(ADB)$ adb shell settings put system user_rotation 2
// 270°
(ADB)$ adb shell settings put system user_rotation 3
```

## 默认永不休眠

```diff
(SDK)$ vim device/rockchip/rk3576/overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml
-    <integer name="def_screen_off_timeout">60000</integer>
+    <integer name="def_screen_off_timeout">2147483647</integer>
```

## 默认无锁屏

```diff
(SDK)$ vim device/rockchip/rk3576/overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml
-    <bool name="def_lockscreen_disabled">false</bool>
+    <bool name="def_lockscreen_disabled">true</bool>

$ vim device/rockchip/rk3576/overlay/frameworks/base/core/res/res/values/config.xml
+    <!-- Is the lock-screen disabled for new users by default -->
+    <bool name="config_disableLockscreenByDefault">true</bool>
```
