Need help with VoLock? This page provides practical setup and troubleshooting guidance maintained by the JustGuider app team.
Quick checks
- Update VoLock from Google Play before troubleshooting.
- Grant microphone access only when setting up or using voice recognition.
- Configure and remember the available fallback unlock option before relying on voice unlock.
- Test the lock screen while you still have access to your normal device security settings.
Common VoLock issues
Voice recognition does not respond
Check microphone permission, move to a quieter place, and repeat the saved phrase clearly. Restart the app if Android has stopped microphone access.
The lock screen behaves differently after an Android update
System updates can change lock-screen and background-app behavior. Reopen VoLock, review its permissions, and complete setup again if needed.
You cannot use the voice option
Use the fallback method configured in the app. VoLock does not replace the security protections built into Android or your device manufacturer’s recovery options.
Contact the JustGuider app team
If the issue continues, send the app name, app version, Android version, device model, and the exact steps that reproduce the problem. A screenshot is helpful when it does not contain private information.
For your safety, never send passwords, voice unlock phrases, payment details, private photos, or one-time security codes. Support will not ask for remote access to your device.
