What is system UI tuner in Android Marshmallow? Why is it hidden?

Like previous versions of Android, Android Marshmallow 6.0 also has a few hidden features.

These hidden features are usually not ready for public release, although they are usually stable enough. Sometimes, they are also different from beta features because beta features will be very likely released publicly in the future.

However, hidden features are more or less for testing. They may be removed from future releases, or incorporated into other features.

System UI tuner in Android Marshmallow 6.0 is definitely one of the most interesting hidden features in Android 6.0. And Google actually wants you to try it.

With system UI tuner in Android Marshmallow 6.0, you can:

  • customize the quick settings menu;
  • customize status bar;
  • use demo mode.
  • enable embedded battery percentage (in the battery icon in status bar).

Please note,  because system UI tuner in Android Marshmallow 6.0 is a hidden feature, some Android vendors may choose to remove them.

Update: in Android Nougat, you can customize quick settings panel directly without going through system UI tuner.

In other words, the feature of customizing quick settings panel in system UI tuner was a formal feature in Android Nougat.

How to enable system UI tuner in Android Marshmallow?

To enable system UI tuner in Android Marshmallow 6.0, you may follow these steps:

Step 1: Access quick settings

Identical to the two methods of accessing quick settings in Android Lollipop, you can access quick settings in Android Marshmallow with one of the following two methods:

  2. Swipe down from the top of the screen twice with one finger.

Step 2: Tap and hold the gear icon

Once quick settings panel is accessed , tap and hold the gear icon as shown below.

The gear icon will then rotate. You can release your finger from the gear icon when it rotates.

Now, you should be directed to Settings page with a pop out message (as shown below in the screenshot):

Congrats! System UI Tuner has been added to Settings.

Please note, if you release your finger from gear icon too early (without seeing the icon is rotating), you will simply brought to Settings page without enabling system UI tuner in Android Marshmallow. You have to try again.

Now you can:

Please note, some items may not be shown in your quick settings even you can see them in system UI tuner page. You need enable the corresponding features in Settings once.  These features include:

    I have an HTC one m9 on Android marshmallow and I believe that HTC removed the system ui tuner from their build. Would anyone know of a way to hack it back into place?

    Looks like it’s the same with the Galaxy S7 – at least, it doesn’t show up when you follow any of the guides I’ve found online.

    There is no “gear-shaped settings button” in status bar.

    The notification bell rangs and as soon i drag the status bar there will be no such a word of notification, it displays “No Notifications”.

    The System UI Tuner menu changes over time as Google adds or removes features, so it’s worth checking out again whenever you get an update to Android.

    I think it is hilarious that people do not read before asking. So many times you said Samsung disabled it, and people keep asking.
