[How to] Find the System UI tuner in the third developer preview of Android 6.0
If you flashed or received the most recent developer preview via OTA, you may have not noticed that there is a little gear icon in your settings shortcut on the toggle area. That little icon is very very important as you have to press it for about 5 seconds to activate or deactivate the System UI tuner. If you activate it, it will appear somewhere at the bottom of the settings app.
In order for the above advice to work however, you will need to have developer options enabled, although it could work with developer options disabled as well.
The System UI tuner allows users to change some granular features on their device, for example: remove unwanted icons from tray, add battery percentage in the battery bar on tray, or rearrange some quick settings.
This is a great feature that attracted praise from Android 6.0 preview users. It would be great if Google will keep it in the final release of Android Marshmallow.
