More recent reports said that the Galaxy Note 9 will be the first Samsung handset to have a fingerprint sensor under the screen, and then Synaptics' announcement came along, suggesting there's a chance the Galaxy S9 will make use of its technology.
Vivo, a company whose name might not be familiar to you, is actually a top-five smartphone maker thanks to its large presence in Chine.
Synaptics has just recently officially announced the world's first in-screen fingerprint sensor and said that one of the top 5 biggest phone makers globally will embed the new sensor in a phone next year.
According to Patrick Moorhead, a contributor at Forbes that got to test a pre-production model, the Synaptic solution is "fast and simple". In order for the technology to work, the finger has to be illuminated, so the scanner can read the reflection on the finger scan.
Apple, meanwhile, made a decision to ditch an actual fingerprint scanner altogether with the iPhone X. The iPhone X is Apple's first iPhone to not have Touch ID. Synaptics claims that the Clear ID is twice as fast as the 3D facial biometrics.

When asked if there was a hangover after losing to Pep Guardiola's men, Mourinho said: "Fatigue, yes, but hangover - no". City insiders say their players and staff did nothing wrong and were reacting to Mourinho's aggressive manner.
While this is slightly different from how we unlock our phones now, Moorhead expects Vivo to improve the experience by only requiring users to lift to wake the device, so at that point, they can just place their finger on the glass to unlock it, without the need to press any other buttons.
Overall, it looks like the Synaptics Clear ID technology is very reliable based on Moorhead's experience. Earlier in the year, Qualcomm revealed to Digital Trends that it expected in-screen fingerprint sensors to launch in consumer products beginning in summer 2018.

Manufacturers like Apple are instead going with fingerprint sensor, while others like Samsung and OnePlus have moved it to the back of the smartphone - not the most convenient location.
The new in-screen sensor is a small CMOS device placed below an AMOLED screen. Better yet, it still functions with the same security and dependability as a conventional fingerprint sensor, meaning it can be used not just for unlocking, but payments as well.
