Double Tap to Sleep

❕ This feature requires Niagara Pro and a phone that runs at least Android 9. We're also offering a workaround for older phones that are rooted; you can read more about it here.

This feature lets you turn off the screen quickly by double-tapping on the alphabet (or on the screen's left side).

To enable the quick-lock gesture, go to Niagara Launcher’s settings > Features > Quick lock gesture.

How to enable the accessibility service?

Open Android's settings > Accessibility. Niagara Launcher's accessibility service is listed here or in a submenu (which could be named "installed services" or similar). Tap on this option (it should be named  "Niagara Launcher") and turn it on.

I cannot enable the accessibility service

If you get the error message "Restricted setting" when you try to turn on Niagara Launcher's accessibility settings, follow this guide.

Enabling the service causes a button to appear. How to turn it off?

Here's how.

Why does the gesture only work on the alphabet?

If you could also double-tap on the home screen or app list to lock the screen, every app launch would take longer. That's because Niagara Launcher would have to wait a bit after you tap on an app to check if you're doing a single-tap or double-tap gesture.
