Ultrasonic fingerprint sensor patch for Galaxy S10, S10+ and S10 5G boosts unlock accuracy, speed

Galaxy S10, S10+ and S10 5G customers are receiving and OTA patch designed to address complaints about the accuracy and speed of Samsung’s new Ultrasonic Fingerprint sensor. Our Galaxy S10+ has also received the update and like other users are reporting, we can also report that it has reduced the fiddling around previously required to make the device unlock. The patch is just 6.9 MB in size and looks to be rolling out widely.

The Galaxy S10 line are the first devices from Samsung to feature an in-screen finger print sensor. The Galaxy S9 and Note 9, for example, featured a fingerprint sensor in the rear of the device that was very effective. The new in-screen technology, however, is purportedly more secure as its ultrasonic sensors provide for a 3D level of recognition.

Also alleged to be more secure than the previous method, however, it has already reportedly been hacked by a Reddit user who used resin to create a 3D model of a fingerprint. While this requires a level of sophistication to execute, it does raise question marks over the systems effectiveness. It is not yet known whether the patch defeats this method.
