There is no gyroscope to detect device orientation on my device. So I want to rotate screen orientation when user pressing a key such as ALT key or setting "Auto-rotate screen" on in Settings>Display.
1. Modify the label of Auto-rotate screen in strings.xml

4. Remove android:screenOrientation field in AndroidManifest.xml
packages/apps/Launcher2/AndroidManifest.xml
packages/apps/Contacts/AndroidManifest.xml
packages/apps/Phone/AndroidManifest.xml
packages/apps/Settings/AndroidManifest.xml
packages/apps/VoiceDialer/AndroidManifest.xml
(The End)
