Frequently Asked Questions
How does the Intruder Selfie feature work?
When someone attempts to unlock a locked app or media file with an incorrect password, the app automatically activates the front camera and captures a selfie. This provides evidence of unauthorized access attempts. You can review all captured intruder photos in the dedicated Intruders section.
Can I lock my default system apps?
Yes, Fingerprint Lock Screen allows you to protect default system apps including Messages, Phone, Settings, and other built-in Android applications. This prevents unauthorized access to critical phone functions and personal information stored in these apps.
Will locking apps slow down my phone?
No. The app is designed with low memory usage architecture specifically to avoid performance degradation. It operates efficiently in the background without consuming significant device resources or battery life.
What happens if I forget my lock password?
Unfortunately, if you forget your password, you may need to uninstall and reinstall the app, which will remove all app locks and hidden media. Create a strong but memorable password, or use your device's fingerprint as your primary authentication method to avoid this issue.
Is the media vault truly hidden from other apps?
Yes. The media vault removes files from your standard gallery application and stores them securely within Fingerprint Lock Screen. Other gallery apps cannot access or display these hidden files. You must unlock the vault within Fingerprint Lock Screen to view your media.
Fingerprint Lock Screen is a comprehensive security application that protects your apps and media files through biometric and password-based authentication methods. Beyond traditional app locking, it offers an integrated media vault for hiding sensitive photos, videos, and documents while featuring an innovative intruder selfie system that captures unauthorized access attempts.
Why Choose Fingerprint Lock Screen?
Fingerprint Lock Screen combines multiple security layers into a single intuitive application, eliminating the need for separate app lockers and media vaults. The intruder detection feature provides forensic evidence of unauthorized access attempts, while flexible authentication options accommodate diverse user preferences. Its app categorization system simplifies managing security across your entire device.
Multi-Factor Authentication: Lock apps and media using fingerprint, PIN, pattern, or password combinations for maximum flexibility.
Intruder Detection: Automatically captures selfies when someone attempts to access locked apps or hidden media with incorrect credentials.
Media Vault: Create a secure gallery vault hiding photos, videos, audio files, and documents from standard gallery applications.
How It Works
Install the app and grant necessary permissions for fingerprint access and photo vault functionality. Select which apps to lock from the comprehensive app list, customize authentication method per app, and optionally hide media files in the vault. The app automatically categorizes applications and monitors new installations, sending alerts when new apps are installed on your device.
Who Should Use It?
Fingerprint Lock Screen is ideal for privacy-conscious users, parents managing children’s device access, and anyone storing sensitive information on their phone. It’s particularly valuable for users with personal photos or documents requiring multi-layered protection and those wanting forensic evidence of unauthorized access attempts through intruder detection.

App does what it promises overall. I appreciate the multiple lock options and media vault feature. However, after about an hour, I need to reopen the app for locks to work properly. Recent updates seem to have improved this issue. Ads can be intrusive but understandable for a free app.
