Starting with Marshmallow Google included a new hidden settings menu with experimental features. This menu called the System UI Tuner is a great way to access tools that may not be quite ready to be called stable but are an excellent way to get eyes on possible upcoming features.

It’s worth noting that third-party manufacturers are free to disable this menu on their custom builds of Android so it may not be available on your particular device.

The contents of the UI Tuner will vary depending on what version of Android you’re running.

System UI Tuner let you choose which icons to show in the status bar. For the majority of the icons you can simply turn it off or on but there are some additional controls for time and battery. It is a great tool to give you a bit more customization and it cleans up unnecessary icons which crowd your status bar.
