About this app

Lock Screen is a lightweight, accessible utility designed to help users lock their screen easily without needing to interact with physical hardware buttons.

Designed for:
✓ Users with motor impairments or difficulty pressing physical hardware buttons.
✓ Extending phone hardware lifespan by offering an accessible on-screen locking method.
✓ Quick, ad-free screen locking functionality.

Prominent Disclosure & Accessibility API Usage:
This app uses the AccessibilityService API solely to perform the system-level action of turning off and locking the screen.
• Why Accessibility API is used: The AccessibilityService API allows the app to lock the screen without invalidating biometric authentication (such as fingerprint or face unlock) on Android 9 (Pie) and above.
• Data Privacy: This app DOES NOT collect, store, or share any personal or sensitive user data via the AccessibilityService API. The API is used strictly to execute the screen-lock action.

Permissions Used:
• Accessibility Service: Used exclusively to perform the screen lock action.
• Device Administrator Permission: Used on older Android versions as an alternative method to lock the device screen.

How to Uninstall:
1. Go to Settings > Security > Device Administrators > Uncheck "Lock Screen".
2. Go to Settings > Apps > Lock Screen > Tap "Uninstall".

Ratings and reviews

In ancient history, I relied on a tap-to-lock feature on an older phone and OS, and then the feature was no longer supported by the system software on a later phone. This app worked flawlessly for many years. It suddenly stopped working in 2026 due to an OS upgrade, and the developer got on top of the issue and released the necessary update. And now it works like a charm, once again. Thank you so much!

Installed on Pixel 10. Works very well, as described. Does not interfere with other apps. I like the fact that it has an icon that I put as a shortcut on my home page as opposed to being fully transparent. A double tap feature would have made it more perfect.

Must have to reduce wear on the power button! Much better than similarly named apps. Simple & effective, with just the required permissions.
