Features & Capabilities

Screen Off and Lock is a practical Chrome extension designed to help users turn off and lock their phone screens without repeatedly pressing the physical power button. This reduces wear and tear caused by frequent use of the power button, enhancing device longevity.

The extension offers two convenient launch icons: one to perform the screen off and lock function directly, and another for accessing settings and managing premium account features. It requires Device Administrator permissions to enable seamless screen locking and Accessibility Services API for fingerprint support on compatible phones.

Users can easily manage permissions and uninstall the app through device settings. By offloading the power button's workload, Screen Off and Lock provides a user-friendly and effective solution to protect your handset’s hardware while maintaining quick and secure screen control.
