The ability to customize virtually every square inch of your Android smartphone is a big draw for many users. While that means rooting the smartphone for some users, that's a bridge too far for most of us -- especially when you customize a great deal without resorting to rooting.
Android Marshmallow offers a new set of customization options to users that provide some controls were previously only available via root. This menu is called System UI Tuner and while it is a bit hidden by default, activating it and taking advantage of these advanced customization options is remarkably simple.
1. Swipe down from the top of the screen to reveal the notification panel. Long press on the cog in the upper-right corner for 2 to 3 seconds and then release. If successful, you'll see a pop up saying "Congrats! System UI Tuner has been added to Settings."
2. Scroll to the bottom of the Settings page and tap System UI Tuner.
3. Tap Got It on the pop up message.
So what can you do with System UI Tuner? Here's a quick rundown of the settings you can customize.
