Screen Lock Pro

About this app

Screen Lock Pro 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 the Admin lock feature.

Read write system settings permission to enable the Smart lock feature of the app.

This app uses Accessibility service. It is optional for Android 9 and above. It is used only for taking advantage of the internal Screen Lock function 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 wake-up feature:
☞ Flip cover
☞ Air swipe
☞ Desk option
☞ Awesome shake

Usability enhancements:
☞ ‘Movement listener’ option for uninterrupted reading experience.
☞ ‘On home screen’ for easygoing.
☞ ‘Pause on the landscape mode’ 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.

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 the Screen lock app are most welcome. We’ll do our best to present you desired usage experience.

Ratings and reviews

Love the idea, but for whatever reason, the Lock sound option WILL NOT play at animation start, or animation end, and none of the animations actually apply. Phone still does the normal fade out animation. The only time the lock sound plays is when I select "screen off" or "after device locked", both of which delay the sound for a long time. I'd really like to use this app, but if I can't fix this I may uninstall.

For months now it's giving black screens or even lock outs without touching the button. Sometimes one can go back, often not. I thought it's Android 16 but only after uninstalling, the glitches stopped. It's s great, when it doesn't interfere with other apps, am hoping they find the reason and solve it.

I wouldn't want to operate my phone without this app. I use a flip-cover case and the phone automatically blanks and locks the screen everytime I close the cover. On opening the cover, it just requires my thumb print to wake the phone again. After some initial problems setting up, it now seems to be working as I need, but Android loves to mess with permissions so it is, sometimes, necessary to re-visit the settings.
