System UI Tuner

First introduced in Android 6.0 (Marshmallow), Google included a hidden menu in stock Android with experimental options called System UI Tuner. The option to launch System UI Tuner in Android version 9 and newer has been removed by Google, but the utility still exists in the system. This application will launch it if present. This will work on all stock AOSP and Pixel builds of Android 9+. Third-party device manufacturers may choose to disable this menu completely in their Android builds. This does NOT work on Samsung devices! Samsung has removed the utility from their system software.
