How to: Turn on System UI Tuner in Android 6.0 Marshmallow Preview 3

systemui tuner

The System UI Tuner that was first introduced in Android M’s preview 1 and 2 is back again in Android 6.0’s preview 3, only it’s not as easy to find as it once was. In fact, Google has completely hidden the setting unless you perform a secret action to enable it. 

To enable System UI Tuner in Android 6.0 Marshmallow preview 3, pull down your notification shade and long-press on the Settings gear icon for up to 5 seconds. Once you let go, you should see a pop-up with the message “Congrats! System UI Tuner has been added to Settings.” And as that message suggests, you can head into settings, scroll to the bottom, and find an option for System UI Tuner.

With it enabled, you can then tweak your quick toggle tiles, add or remove items from the status bar, and even enter Demo Mode.

To turn it back off, tap the action overflow menu from within the System UI Tuner section and choose to turn it off. You can also long-press on the Settings icon again for 5 seconds.

    Is this where the dark UI option should be? Does this mean it won’t be in the final? I do greatly prefer dark themes, so I was really looking forward to that feature. 🙁

        Lol I was reading how to get it all setup on phones sounds confusing. I know a lot about phones but not how to do this kinda stuff to them

    I think they need to slow down a bit. Still some issues with 5.0 that they need to fix first before they move on to other OS updates. The few functions that I have seen so far have been amazing and I would love to have them on my phone, but I think that 5.0 requires a little too much work still for them to be planning out the next OS.

      I don’t think you understand how this works…

        I do. It’s a business decision. And the actual rollout of marshmallow is still a ways away, giving the dev’s time to patch, fix and add new features to 5.0. But if you look at the number of devices that are currently running lollipop is still only in 3rd place when it comes to percentage. Most of those phones are either the stock Android people who had no issues upgrading or people with newer generation phones that were built out of the box with 5.0 or above. I just think that they could make a lot more headway by simply holding off, focusing on killing bugs, and then begin the rollout of marshmallow.

      Right, because they’re just going to roll out new features without fixing anything in the previous version ….

    Hope there will be a way to customize the system wide fonts. That’s what I enjoy about Xposed + Fontster

  • litobirdy

    wow, is this like a less featured Tweaksbox kind of thing? Make rooting even less necessary when customizing status bars etc etc

    • booshcity

      Yup, I’m hoping for a long list of system tweaks 🙂
