Smart Screen On Off is a free utility tool that makes managing your device's screen effortless. Instead of manually pressing the power button, this app utilizes the proximity sensor and double tap on the Home Screen to automatically turn the screen on or off.

This feature is especially useful when pressing the power button is inconvenient or you want to preserve its physical use. What's more, Smart Screen On Off's power head — positioned conveniently on your screen — offers quick access to locking the screen. This innovative approach provides ease of use and helps prolong the lifespan of your physical power button.

Screen security ensured upon approving permissions

To ensure security, Smart Screen On Off requires you to approve the Device Administrator permission, which is only used for locking the device when the screen is turned off. This feature can be enabled through the app's settings. Approved permission for Accessibility services is also required so that the tool can detect the home screen and enhance its other functionality.

As mentioned, the app's functions include a double-tap on the Home Screen to turn off the screen. It also uses the proximity sensor to automatically detect when to power the screen on or off, adding convenience to your device usage. You can customize settings such as disabling the feature when the screen rotates horizontally and setting delays for screen on/off to avoid accidental activation.

The app's efficiency shines as it uses a minimal amount of resources, consuming only a maximum of 5 MB of RAM. It even has the capability to automatically turn off the screen when your phone is placed in your pocket. However, despite these range of useful features, it's worth noting that there are occasional issues with the app's finger scanner functionality.

Efficient screen manager

Smart Screen On Off presents an effective solution for managing your device's screen without relying heavily on the physical power button. Its user-friendly interface, along with the innovative use of the proximity sensor and Home Screen double tap, makes it a valuable addition to your device's toolkit. However, it's important to keep in mind the occasional finger scanner issues while enjoying the convenience this app offers.
