By default, the Android operating system has a feature that’s called “always on,” which allows you to see when your phone is in sleep mode.
When this feature is turned on, your phone wakes up automatically and lets you control it.
The downside of this feature isn’t that it can’t be disabled, but that it’s difficult to control it with a single tap.
In this tutorial, we’ll show you how to enable this feature in Android’s Settings app and then set up a simple system to do this on your phone.
This will let you take control of your phone when it’s in sleep, and let you do some cool things like turn off the display when you’re in bed.
