About Screen Lock
Screen Lock protects your device's power button while giving you fast, flexible ways to lock and wake your screen. Instead of relying solely on the physical button, this app offers multiple locking methods tailored to how you actually use your phone.
Choose the security method that suits you. Admin lock and Smart lock systems give you the adaptability to switch between protection approaches. Lock your screen instantly through shortcuts, a dedicated widget, notification controls, or an interactive floating widget — all with a single tap. The app works seamlessly with your device's existing security and respects your Do Not Disturb settings and notification sound levels.
Beyond traditional button presses, this app uses your device's sensors to unlock creative locking and wake-up options. Flip your cover to lock, use air swipe gestures, or shake your phone to wake it. These alternative methods add convenience while reducing wear on the physical power button. A movement listener keeps your screen active during reading sessions without triggering accidental locks, and a landscape pause option prevents interruptions while gaming or watching video. The app also integrates with call detection, ensuring it won't interfere with your device's normal calling functions.
Personalization transforms how your device feels when you lock and unlock it. Choose from animated illustrations, select your preferred icon design — including Metallic and Material styles — and customize sounds to match your preference. Vibration feedback and sound volume controls let you create a lock and unlock experience that's uniquely yours. For the smoothest animations, the app recommends adjusting your device's "Transition animation scale" and "Animator duration scale" settings to 1x.
Screen Lock runs on Android 9 and higher, using Device Administrator and accessibility services (on Android 9+) to deliver reliable performance. Before uninstalling, remember to deactivate device administration in your settings. If you want full control over lock and unlock sounds, you can disable your device's default audio feedback.
Reduce physical button strain while gaining faster, more flexible control over your screen. Screen Lock continues to evolve, focusing on delivering the protection and convenience your device deserves.
