Unlock Selfie is a free Android application developed by Romanco under the Utilities & Tools category. The app helps you find out who touched your phone by taking a selfie of the intruder each time they try to unlock your device. With the app installed, you can easily find out who unlocked your phone, who touched it, who tried to unlock it, and who is using your phone.

The app is especially useful for those who leave their phone in crowded places or share their phone with others. It takes a photo every time someone tries to unlock your phone, whether they are successful or not. The photos can be saved in the gallery, inside the app, or in the Cloud for easy access. The app also needs administrator access to take a selfie when someone tries to unlock your screen.

To use the app, you need to provide it with necessary access to work. The photos are saved inside the device by default, but it is recommended to set up synchronization with the disk for backup. If you have any questions or concerns, you can contact the developer through their Facebook page or via email.

Overall, Unlock Selfie is a great app for those concerned about their privacy and security. It provides a simple and effective solution to find out who touched your phone without your permission.
