The hidden System UI Tuner menu adds more settings to the many ways you can customize your Android device. You can change settings such as whether the battery indicator shows on the status bar and whether that icon shows the percentage of battery left.
The System UI Tuner menu is not available on every Android device. We tested it on a Google tablet, a Samsung tablet, and an LG phone. We were only able to access the System UI Tuner menu on the Google tablet, but not on the Samsung or LG devices.
Enabling the hidden System UI Tuner menu is easy, if your device supports it. Here are some of the settings you can currently change using it (as of the time this article was written).
Enabling The System UI Tuner Menu
To enable the System UI Tuner menu, swipe down from the top of the screen to open the Quick Settings menu. Then, hold your finger down on the “Settings” (gear) icon until it starts spinning, which should take about 5-7 seconds.
NOTE: When pressing down on the “Settings” icon with your finger, it can be hard to tell when the icon starts to spin. We found it was easier to tell if you use a stylus.
Lift your finger once the icon starts to spin. The Settings automatically opens and a message displays saying that the System UI Tuner has been added to Settings.
When the System UI Tuner menu is enabled, there’s a small wrench on the right side of the “Settings” gear icon.
Opening The System UI Tuner Menu
To open the System UI Tuner menu in the Settings, scroll to the bottom of the “Settings” screen and tap “System UI Tuner“.
A warning dialog box displays, giving a disclaimer about how these features may change, break, or disappear in future Android releases. Tap “Got It” to close the dialog box.
Changing The Status Bar Settings On The System UI Tuner Menu
The System UI Tuner menu opens, currently showing three options. First, we’ll go over the “Status bar” option, so tap on that.
You are also reminded again, at the bottom of the menu, about how the features in the System UI Tuner menu are experimental and may change, break, or disappear in future updates to the Android system.
A list of settings displays. These settings are icons that can, and will, display at one time or another on your status bar. If there are some settings you don’t use, you can turn them off.
To hide a setting on the status bar, click the slider button for that setting so it turns gray. Enabled settings have blue slider buttons.
One of the more useful settings is “Battery“. You can hide the battery icon if you choose, or you can display it with or without (default) the percentage on the icon.
Tap the “Battery” option and select whether you want to show the icon at all, and whether you only want to show the percentage when charging or show it always.
You can also change the “Time” to show hours and minutes, to show hours, minutes, and seconds, or not display the time at all.
Changing The Do Not Disturb Settings On The System UI Tuner Menu
Now, tap the back button on your device to return to the main System UI Tuner menu and then tap “Do not disturb“.
Turn on the “Show with volume controls” slider button to show the “Do not disturb” slider button when using the volume controls. The “Volume buttons shortcut” setting allows you to turn on “Do not disturb” by turning the volume all the way down using the volume button.
Changing The Power Notification Controls On The Tuner Menu
Tap the back button again on your device to return to the main System UI Tuner menu. This time, tap “Other” and then tap “Power notification controls“.
The Android system provides a set of simple options to adjust notifications for each app in the settings. You can block all notifications for each app (in “Apps” under “Device“), silence all notifications for all apps (in “Sound” under “Device“), or prioritize them to override the “Do not disturb” mode (also in “Sound” under “Device“).
Tap the “Power notifications controls” slider button to turn the feature on. The button is blue when the feature is on. This will add a more granular six-level scale to the notification settings for each app. The levels are described on the “Power notification controls” screen.
The “peek” feature listed under the various levels is the process of popping a little card over the display.
With the “Power notification controls” setting on, you’ll see a line under “Importance” with six dots on it when you go to “Settings” > “Notifications” and select an app in the list.
Select the level of importance for the selected app’s notifications by tapping on a dot on the “Importance” line. The levels go from “” on the left to “5” on the right.
The options below the “Importance” line vary depending on the selected level of “Importance“.
Disabling The System UI Tuner Menu
If you decide you don’t want to use the settings in the System UI Tuner menu, you can easily remove the menu from within the Settings. You can do this either in the Settings or from the Home screen.
From the System UI Tuner menu screen in the Settings, tap the menu button (three vertical dots) in the upper-right corner of the screen.
Tap “Remove from Settings” on the pop-up.
To remove the System UI Tuner menu from the Settings while on the Home screen, drag down from the top of the screen and then tap and hold down on the “Settings” (gear) icon again, until it spins.
For either method you use to remove the System UI Tuner menu from the Settings, a dialog box displays asking if you want to remove the menu and stop using all of its features.
If you’re sure you want to remove the System UI Tuner, tap “Remove“.
