About System UI Tuner APK
In Android 6.0 (Marshmallow), Google introduced a hidden menu called System UI Tuner, which adds experimental options to stock Android.
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. The application will start it if it is present.
You can use this on all stock AOSP and Pixel builds of Android 9+. The third-party device manufacturer may choose to disable this menu entirely in their Android builds. You will not be able to use this feature on Samsung devices! Samsung has removed the utility from its system software.
Conclusion
System UI Tuner APK allows users to access the hidden menu with experimental options on stock Android 9+ devices. It provides a convenient way for users to customize their system settings and preferences. However, it is important to note that the APK may not work on all devices, as some manufacturers have chosen to remove the utility from their system software.
