Enable System UI Tuner on Android: Access Hidden Features

Accessing Experimental Features with the System UI Tuner
Beginning with the Marshmallow release, Google integrated a concealed settings panel offering access to experimental functionalities. Known as the System UI Tuner, this menu provides a means to test tools that haven’t yet reached full stability. It’s an excellent opportunity to preview potential future features.
It’s important to understand that Android device manufacturers can choose to disable this menu within their customized operating system versions. Consequently, its availability isn’t guaranteed across all devices. For instance, Samsung and LG have both opted to disable it on their devices that aren’t part of the Nexus line.
Enabling the System UI Tuner
Activating the System UI Tuner on compatible phones is a straightforward process. Simply expand the notification shade by pulling it down twice, revealing the Quick Settings panel. Then, press and hold the settings cog icon for several seconds.
The icon will begin to rotate, and a small wrench icon will appear beside it. This visual cue confirms that the System UI Tuner has been successfully enabled.
To locate the tuner, navigate to the bottom of the main Settings menu. Depending on your Android version, “System UI Tuner” will be displayed as either the final or penultimate option.
Exploring the Tuner’s Contents
The specific options available within the System UI Tuner will differ based on your Android version. For example, Marshmallow includes a toggle to “Show embedded battery percentage.”
This same setting can be found within the “Status Bar” section in Nougat, demonstrating the evolving nature of the tuner’s interface.
Take some time to explore the various settings within this menu. Numerous interesting features are hidden here, particularly within the Nougat version of Android.
Discovering these features allows users to potentially influence the development of Android by providing early feedback.
The System UI Tuner is a valuable resource for tech enthusiasts and those eager to experiment with upcoming Android functionalities.
