## Description

**Lock Screen** is a lightweight, ad-free Android utility that lets you turn off and lock your phone screen without pressing physical hardware buttons. It is designed for users with motor impairments, accessibility needs, or anyone looking to reduce wear on their device’s buttons.

The app uses Android’s AccessibilityService API solely to perform the screen-lock action and does not collect, store, or share personal or sensitive data. On Android 9 and newer, it can lock the screen while preserving biometric unlock compatibility. Older Android versions may use Device Administrator permission as an alternative.

Some users dislike the permission prompts, and there are issues with uninstalling or reconfiguring after device changes. Overall, it’s well-liked for simplicity and usefulness, but reliability and compatibility concerns limit consistency.
