You can do a lot with Android. Google’s mobile OS is famously open to customisation, and plenty of apps take advantage of that fact.
But you might not know that Google itself keeps a few settings tucked away in a hidden menu called the System UI Tuner.
It’s not available on every device — you’ll have less luck if yours has a heavy UI skin — but it’s worth checking out to see which features might be coming to future Android versions. Some of the features it brought to last year’s Android 6.0 Marshmallow update — where it was first introduced — are now standard with Android 7.0 Nougat.
Here’s how to access the System UI Tuner, and a quick rundown of what it can do with Android 7.0.
If you're familiar with the chrome://flags shortcut in Google Chrome, the System UI Tuner is more or less that. To activate it, pull down the Quick Settings menu, then hold down on the gear icon in the top right corner until it starts spinning. It should take 5-7 seconds.
To find the Tuner itself, go into Settings, then look under the 'System' section. It should be toward the bottom.
You'll see this warning the first time you hop in, giving you the usual spiel about how all of this is hidden for a reason. For what it's worth, I've seen the occasional moment of sluggishness in my time tinkering with things, but I've yet to run into any device-bricking bugs.
From there, you can mess with how things look in Android's status bar. One handy toggle lets you see the battery percentage over the top of that icon, for instance.
You can set it so that number is always showing, never showing, or only showing while charging.
