Although there are quite a few smartphones on the market with optical in-screen fingerprint scanners, none has the ultrasonic one so far. Samsung was hoping to be the first smartphone manufacturer to release a phone with Qualcomm’s second-gen ultrasonic fingerprint reader. As a result, this would have made the Galaxy S10 stand out and it would have been the first device to feature such a sensor. Unfortunately, Huawei and its upcoming Mate 20 Pro may beat Samsung to it.

The famed Vivo NEX also features an in-display finger scanner but it is of the optical variety and was procured from Gudix, a Chinese manufacturer. However, Qualcomm has upped the game with its ultrasonic fingerprint sensors. The latest tech guarantees accuracy for glasses that are up to 800 microns thick. The first-gen ultrasonic sensor could work accurately through a display that was up to 300 microns thick. However, Huawei seems to be obsessed with bagging the title of being the first when it comes to the newest technologies.
