The Google Now gesture included in the Google Now Launcher and on Nexus devices isn't something I regularly utilize, and you might not either. There is a way to disable it, which is a good idea if you were executing it accidentally, but what's even better than disabling it? Repurposing it!
We've already showed you how to launch applications using the Google Now gesture, but now there's another way to take advantage of this shortcut, thanks to developer Keerthi Kumar. By using his new app, you'll be able to save some wear and tear on your power button and lock your device by way of the upward-swipe Google Now gesture.
The installation is simple, but you will need to ensure that your device is rooted. If it's not, take a look at our rooting guide for Android, then report back here. Also, since ScreenOff is not on Google Play, you will need to make sure "Unknown sources" is enabled so you can install the APK file.
When you swipe up from the bottom of the display to perform the Google Now gesture, you will be prompted to select how you would like to complete the action. Select "Screen Off," then "Always."
On the XDA thread, plenty of the issues reported were a result of this step. When you first perform the gesture, you will need to wait a second or two for the Superuser request to pop up, then select "Grant." If the app is not granted access through this popup, you will have issues, resulting in the need to uninstall and reinstall the app.
With Superuser access granted, you can now swipe up to turn your screen off and lock the device. And unlike other screen-off apps, like Pocket Lock or Gravity Screen, ScreenOff will not disable the Smart Lock feature introduced on Lollipop.
Along with the Google Now gesture, ScreenOff offers a couple of other ways to turn your screen off. Using the icon in the app drawer or a widget, you can turn your screen off without using the hard key. Some people have had issues with the widget not being applicable, so just be aware of that.
This modification may seem simple or small, but considering the amount of times you press the power button, this can prevent wear and tear from ruining it down the line.
