It seems that Samsung may have thrown away years of progress and rely on its biometric security technology to reduce the rings. Although it was never as accurate and safe as Apple's face ID, Samsung's combination of face and iris recognition to the Galaxy S10 was, at least, reliable. Now it is gone and even Samsung's ultrasonic fingerprint scanner turns out to be less useful than the company has done that sound.
Fingerprint sensors on the screen are not entirely new but while other OEM users such as Huawei, Xiaomi, OPPO and the like are already trying to perfect the more traditional optical fingerprint scanner, Samsung started square by adopting Qualcomm's ultrasonic fingerprint scanner technology. While it may have advantages over optical sensors, users discover that the drawbacks easily outweigh them.
Users report on how unreliable the technology is, despite the announcement that it should actually be more reliable. While the ultrasound technique should look, or rather hear through oil, dirt and even scratches, it fails ironically in dry environments, dry fingertips or scratchy fingertips. Online complaints tell you how the sensor will fail several times, especially when transactions are made.
It wouldn't be bad if it wasn't the only secure biometric authentication available on the phone. The only other option is to enter a PIN or password. In the light of fingerprints and facial recognition, it is almost like going back to the dark ages.
Samsung promises that everything it needs is software updates to improve performance, updates that could not come earlier. But though they will hopefully address the specific problem, the Galaxy S1
