Description
Screen Lock, is created to extend the life of the hardware power button by using the feature within the app. Support for both Admin lock and Smart lock system. Easy to Screen off and lock the device depending on your selected preferences.
This app uses the Device Administrator permission. Necessary for the app to lock with Admin lock. Read write system settings permission to enable the Smart lock feature if needed.
This app uses Accessibility service. It is optional for only Android 9 and above. Used only for taking advantage of the internal Screen Lock option to overcome the delay in the Smart lock feature.
One tap to off and lock the device using: ☞ Admin lock (Shortcut) ☞ Smart lock (Shortcut) ☞ Screen lock widget ☞ Admin lock and Smart lock from notification ☞ Floating widget
Screen lock using available device sensors for both lock and wakeup feature: ☞ Flip cover ☞ Air swipe ☞ Desk option ☞ Awesome shake
Usability enhancements: ☞ ‘Movement listener’ option for a distraction-free reading experience. ☞ ‘On home screen’ for easygoing. ☞ ‘Pause on landscape’ to play games effortlessly. ☞ ‘Pause on call’ to let the device follow its default course of action.
Personalisation features: Animations to pick for Phone lock experience. Vibration feedback upon Phone locked. Lock and unlock sound at varied points to play the tone you love to hear. Sound volume is picked from notification sound as volume and can be further adjusted with ease, also respecting DND mode.
Highly customisable lock icon with an easy-to-use interface. Option to use Metallic and Material icon as a choice for both Admin lock and Smart lock.
Animation speed is adjusted with the “Transition animation scale," and “Animator duration scale”. Our advice, use 1x for the best ‘Screen Off’ experience. The changes may take place after lock and unlock.

I installed it on an old phone with Android 8 and fingerprint sensor, integrated in power button. Need to prevent failure of the fingerprint sensor due to power button overuse. This app works fine (without delay!) with on-screen lock button: quick and easy screen lock. Next I can do quick screen unlock with the fingerprint sensor. Just what I was looking for! Note: after long time of screen lock I wake up the phone with the camera button, next unlock with the fingerprint sensor.

Horrible app - all data lost!!! I've installed it on my phone. I noticed that after locking the screen with this app - the phone requires a pin instead of a fingerprint - incredibly inconvenient! And after reboot my phone this app caused the phone to crash when entering the password. Even save mode didn't help! This ultimately resulted in the loss of ALL data! I really regret that I didn't immediately realize that you should never install an app from any Kumar!

Grossly overcomplicated way to 'lock' screen, which it does not do. Other apps achieve the same thing simply and effectively. Icon has one icon overlaid over another. Icon changes do nothing to the default icon.

Though this free version still works for my newest phone (Galaxy s25+, android 16), while the pro version (which I purchased and used successfully up till this phone) now just crashes whenever I try to use it, I'm still becoming concerned about security with this free version, since it hasn't been updated since 2024! Please update or document assurance that you've thoroughly vetted this version for Android 16 and that it's still secure! I might have to uninstall otherwise. Thanks.
