IntruderCheck

Tips
• IntruderCheck keeps the most recent 10 unlock events. There is no such limitation if you upgrade to PRO mode.
• The latest Android platform requires IntruderCheck to show a notification on the status bar. You can hide it so IntruderCheck is completely running in background.
• Monitoring failed password attempts requires IntruderCheck to be a device administrator; it may fail to capture image if face unlock is enabled.
• If the camera unavailable (either it is in use by other apps or locked by Android system) when the phone is unlocked, the event will still be recorded with a timestamp.

IntruderCheck is a free and ad-free tool that helps you check if there is any intruder who gets access to your device without your consent.

When the service is enabled, IntruderCheck takes a photo using the front camera once your device is unlocked. Images taken are hidden from photo gallery and file managers. The application can also be secured by passcode so that only you can manage and view the images of intruders.

To enable monitoring
1. Launch IntruderCheck
2. Grant permission for camera usage
3. Turn on "Monitor Unlock Events" or "Monitor Failed Password Attempts" as desired

To check intruder images
1. Launch IntruderCheck
2. Tap on "Captured Intruders" to view all records
3. Timestamp of each record is shown under the picture
