Enable and Customize Android’s System UI Tuner

What Is the System UI Tuner?

The System UI Tuner is a hidden Android feature that gives power users deeper control over the system user interface. It lets you add, remove, and rearrange the tiles that appear in the Quick Settings panel, adjust status‑bar icons, and even rename certain tiles. Because it’s tucked away in the Settings menu, most users never see it – but enabling it can make the notification shade feel truly personal.

Prerequisites

• Android 8.0 (Oreo) or newer – the tuner is available on most stock Android builds from Oreo onward.
• Device must support the standard Quick Settings layout (some heavily skinned OEM versions hide the tuner completely).
• Basic familiarity with the Settings app and the notification shade.

Step 1 – Enable Developer Options (If Not Already Enabled)

1. Open Settings → About phone.
2. Scroll down to Build number and tap it seven times.
3. You’ll see a toast message: “You are now a developer!”.
4. Return to the main Settings screen; a new entry called Developer options will appear.

While the System UI Tuner does not strictly require Developer Options, many devices hide the tuner behind the developer flag, so it’s a safe first step.

Step 2 – Reveal the System UI Tuner

1. Pull down the notification shade twice to fully expand the Quick Settings panel.
2. Press and hold the gear (Settings) icon in the upper‑right corner for about 5 seconds.
3. After a brief vibration or toast, you’ll see a message: “System UI Tuner has been added to Settings”.
4. Open Settings again; scroll down and you’ll find a new entry named System UI Tuner near the bottom.

If the long‑press on the gear icon does nothing, your device’s OEM may have disabled the tuner. In that case, you can try enabling it via ADB (see the troubleshooting section).

Step 3 – Access Quick Settings Customization

1. Tap System UI Tuner → Quick Settings tiles.
2. You’ll see two lists:
   • Active tiles – those currently displayed in the Quick Settings panel.
   • Available tiles – tiles that can be added.

This screen is the hub for all tile management.

Customizing Quick Settings Tiles

Adding New Tiles

1. In the Available tiles section, scroll to find the tile you want (e.g., “Battery Saver”, “Screen Cast”, “Night Light”).
2. Tap the tile name. It will instantly move to the Active tiles list.
3. Close Settings and pull down the Quick Settings panel to verify the new tile appears.

Removing Unwanted Tiles

1. In the Active tiles list, tap the tile you wish to hide.
2. The tile disappears from the active list and returns to the available pool.
3. Refresh the Quick Settings panel to see the change.

Reordering Tiles

1. Tap the three‑line “hamburger” icon next to a tile in the Active tiles list.
2. Drag the tile up or down to the desired position.
3. Release to lock the new order. The Quick Settings panel reflects this order immediately.

Advanced Options: Tile Labels and Visibility

Some Android builds expose additional toggles under System UI Tuner → Miscellaneous:

• Show battery percentage – toggles the numeric battery level in the status bar.
• Show carrier label – hides or displays the carrier name.
• Enable “Do Not Disturb” quick toggle – adds a dedicated DND tile.

These options vary by device; not all manufacturers expose every setting.

Troubleshooting and Compatibility

• OEM skins (e.g., Samsung One UI, Xiaomi MIUI) often remove the System UI Tuner entirely. If you cannot see the tuner after the long‑press, the feature is likely disabled by the manufacturer.
• ADB method for locked devices – If you have a computer and USB debugging enabled, you can force‑enable the tuner with the following command: adb shell settings put global sysui_tuner_enabled 1 After running the command, restart the device and repeat the long‑press step.
• Tile not appearing after addition – Some tiles require additional system permissions (e.g., “Screen Cast” needs Wi‑Fi Direct). Ensure the relevant permissions are granted in Settings → Apps → (App name) → Permissions.
• Changes not persisting after reboot – Rare, but can happen on devices with aggressive battery‑saving policies. Adding the affected app to the battery‑optimization whitelist often resolves the issue.

Safety and Risk Considerations

Enabling the System UI Tuner does not modify core system files, so it is generally safe. However:

• Disabling essential tiles (e.g., “Airplane mode”) can make quick access to critical functions harder.
• Some OEMs may treat the tuner as an unsupported feature; future OTA updates could reset the tuner settings.
• Using the ADB command requires USB debugging, which should be turned off after you finish if you do not need it for other development tasks.

Conclusion

The System UI Tuner is a powerful, often overlooked tool that lets Android users shape the Quick Settings panel to match their workflow. By following the steps above you can enable the tuner, add the tiles you use most, and remove the clutter you never touch. While not every device exposes the feature, the majority of stock Android installations from Oreo onward support it, and the ADB workaround offers a fallback for many OEM‑skinned phones. Customize responsibly, keep an eye on system updates, and enjoy a more efficient Android experience.
