Ever wondered whether someone tried to unlock your phone while you were away? Third Eye – Intruder Detection is an Android security app from Mirage Stacks that monitors failed lock-screen attempts and can capture a photo when someone enters the wrong PIN, pattern or password.
The app is designed for users who want an additional way to monitor unauthorized access attempts on their smartphone.
What is Third Eye?
Third Eye works in the background and monitors screen-unlock attempts. When an incorrect PIN, pattern or password is entered, the app can automatically take a photo of the person attempting to access the device.
It also records the last unlock time, provides notifications for failed attempts and maintains photo logs of detected activity.
Google Play lists Third Eye with 5M+ downloads and more than 72K reviews. It is free with ads and in-app purchases.
Testing Setup & Our Experience
We tested Third Eye on a Samsung Galaxy A55 5G running Android 15, focusing on wrong PIN detection, photo capture, unlock notifications, unlock history and photo logs.
After enabling the required permissions, we intentionally entered an incorrect PIN to test whether the app detected the failed attempt. We then checked the notification and photo-log sections to see how the event was recorded.
We also checked the Last Unlock Time feature to determine whether it could help identify unexpected access.
The setup was straightforward, although the app requires special permissions to monitor screen-unlock attempts.

Is Third Eye Worth Downloading?
If you are searching for an intruder detection app, phone security app, wrong PIN alert or unauthorized access detector, Third Eye is worth considering.
Its main advantage is that it provides information beyond a normal lock screen, particularly when an incorrect password attempt occurs.
However, it should be considered an additional security tool rather than a replacement for your phone’s built-in security features. Its effectiveness can also depend on Android permissions and device behaviour.
