Android Marshmallow’s Hidden System UI Tuner

One of the greatest things about the Android operating system is how open and fully customizable it is. Users most often need to take their own approach and implement their own mods and customizations, but what you didn’t know was Android itself gave you that functionality, often times hidden. Today we’ll be taking a look at one of Android 6.0 Marshmallow’s hidden UI Tweaking utilities, “System UI Tuner.”

System UI Tuner is nothing groundbreaking, but it’s a nifty little suite of Google implemented UI Customization options, allowing you to tweak your quick settings and status bar icons.

First off, to enable this feature, you’ll need to have an Android 6.0 Marshmallow device. Drag down your notifications/quick settings pane. Next, you’ll see the little gear icon, which should look a little something like this.


What you’ll want to do is hold down the gear icon (keep it held down, not pressed once) for about 3 seconds. You should then get a little popup message reading something like “Congrats! System UI Tuner has been added to settings.” Once you see this message, the feature has now been enabled.


Head on over to your device’s systems app, and scroll all the way down to find a new section called System UI Tuner.


Once inside the UI Tuner, you’ll see a few miscellaneous tweaks. The first being the most sought after, the Quick settings modifications, then the Statusbar, an embedded battery percentage symbol, and finally “demo mode.”


We’ll begin on Quick settings. Jumping into here, we’re able to see a quick layout of our current quick settings configuration, including the tiles that are made available to us, and the arrangement in which they are in.

From here, you’re free to drag around these icons and move them around, rearranging them to your liking. You can also add some extra tiles that aren’t shown.

If you wish to revert to the stock configuration with the original arrangement and tiles, just click the 3 dotted menu on the top right hand side, and click reset.


The next feature involves the status bar. This menu controls which icons will appear in your statusbar, pretty self-explanatory and straightforward. If you wish to either no longer see a certain icon listed, then toggle the switch off, vice versa.


And finally, we have the Demo Mode. Demo mode essentially drastically “Cleans up”  your entire status bar, and frees it from unnecessary icons and clutter. Not very practical, but it’s there for cleanliness’ sake.

You can enable and disable it straight from the menu.


That’s all there is to System UI Tuner.

If you ever wish to remove the feature and temporarily disable the feature, go ahead and go back to the pull down menu, hold onto the Gear icon once again for 3 seconds, and you’ll be prompted with a popup confirmation dialogue asking you whether or not you want to remove System UI Tuner and stop using its current settings. This will remove any settings you’ve applied as well as removing the menu from the settings app.
