Lock screen - Fingerprint support for Android

App summary

Lock Screen - Fingerprint Support is a free privacy and security utility for smartphones and tablets. It lets you protect your device using a fingerprint (on compatible hardware), a pattern, or a numeric PIN of up to eight digits. The fingerprint option only works on devices that support fingerprint authentication, so on other devices the app will fall back to the PIN or pattern options.

Quick setup and activation

The app offers a simple, visually clean interface that makes setup straightforward.

• To start, open the app and tap the Enable lock screen button to activate the service.
• You will be asked to create and confirm a numeric PIN (up to eight digits) as part of the initial setup.
• If you prefer a pattern, draw it by connecting the dotted circles to establish the pattern lock.

If you want to use biometric unlocking, enable the “Fingerprint Lockscreen” option in your device settings first. When biometric support is unavailable or disabled, the app will prompt for the PIN or pattern instead.

Using fingerprint unlocking

Fingerprint unlocking is the most seamless option when your device supports it.

• Make sure your phone or tablet has fingerprint authentication set up at the system level before enabling the app’s fingerprint feature.
• Turn on the app’s fingerprint option; once enabled, your registered fingerprint becomes the primary method to unlock the device.

Personalization and themes

Beyond locking functions, the app includes visual customization tools so you can tailor your lock screen.

• Choose from many elegant lock-screen themes to change the look and feel of your lock screen.
• You can also set custom wallpapers and edit them by cropping or rotating before saving to your personal collection.

Why use this app

This utility is useful for devices that lack advanced built-in locking features or for users who want an extra layer of protection.

• It prevents casual access by requiring the correct PIN, pattern, or fingerprint before the home screen becomes available.
• It can serve as a practical alternative to other lock-screen and app-lock solutions when you need additional privacy controls.
