Samsung 's Galaxy S10 in - display fingerprint sensor cannot be fooled by a 3D - printed image . We've reached out to Samsung about the issue and will update this post when we hear from them. The device 's existence was discovered by a user of the image - sharing website Imgur , who copied their own fingerprint from the side of a glass . This picture was then fed into inexpensive 3D printing equipment , and then printed on a piece of resin within minutes . The fake print reportedly opens the phone as reliably as the real thing , despite Samsung 's ultrasonic ID software using machine learning to detect artificial prints . Many smartphone features , like banking apps , are secured by the technology .
