Automatically Lock and Unlock Your Android Device with Gravity Screen

 

If only your phone knew when you were looking at it and when you’d set it down or put it in a pocket. That’s exactly what Gravity Screen offers, a free download from the Google Play Store.

Gravity Screen can turn the screen off when you put the phone in your pocket or when you set it down on a table (face up or face down). What’s more, you can keep the screen on with a small shake when it begins to dim, and it can automatically wake up when motion is detected (when you pull it up from your desk, for example).

The sensitivity for these settings can be easily adjusted through the options screen, where you can also temporarily disable the app’s features if you want more control over the settings and access to the Gravity Screen widget then a paid-for Pro upgrade is available, but the app functions fine in free mode too.
 

 Essentially, Gravity Screen replaces the power button on your phone, taking care of the locking and unlocking process for you (it might be worth trying if your phone’s power button is unreliable). Because of the advanced permissions the app requires, you can’t uninstall it in the usual way—use the option at the bottom of the settings screen instead.
