About this app

Screen Lock, is created to extend the life of 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 Smart lock system if needed.

This app uses Accessibility service. It is optional for only Android 9 and above. Used only for taking advantage of internal Screen Lock option to overcome the delay in Smart lock system.

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 destruction-free reading experience.
☞ ‘On home screen’ for easy going.
☞ ‘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 respects DND mode.

Highly customisable lock icon with easy to use interface. Option to use Metallic and Material icon as choice for both Admin lock and Smart lock.

Animation speed is adjusted with “Transition animation scale," and “Animator duration scale”. Our advice, use 1x for best ‘Screen Off’ experience. The changes may take place after lock and unlock.

Note 1: Device administration must be disabled before uninstalling.

Note 2: Disable default device lock and unlock sound, if applying from this app.

Any suggestions for improving Screen Lock app are most welcome. We’ll do our best to present you desired usage experience.

Works flawlessly on my Galaxy S10+, even with Smart Lock. I tried several other apps, but this one is the best. Not only does it work without any issues, it has a great-looking UI, too. (Some of the other apps looked like they were just slapped together.) I happily paid the $1.99 to get rid of the ads and to support the developer. Great job! --Ron

Met my immediate goal of changing my lock/unlock sounds on a device that can't be rooted yet. This app is fantastic. If you really like unique customization, or have a damaged lock button it's a must have. There's a ton of cool features, like flip lock if you use a folio or dual screen case (like me). I ended up getting the pro version, I liled it so much. Great app!

It's so cool! I just can't stop turning off my screen now! Very nice, handy and stable! Since I have a flexible back shell that has a slightly thick opening for the power button, the button is a bit difficult to press. So a button widget icon on each screen (or you can even use the shortcut icon placed in the bottom with the fixed icons) plus several other features, makes for a perfectly thought-out app! Congrats on this!
