Samsung plans to implement the fingerprint sensors under the screen on the Galaxy A family, permanently banishing the option to include it on the side that we saw on the A7. It is what emerges from the agreement signed by Samsung with a Chinese provider of this type of sensors.
Although it was expected that Samsung will introduce the fingerprint sensor on the screen in 2019 only for its flagship smartphones, it seems that as happened with the triple and quadruple camera, this improvement will come to the Galaxy A family first as reported SamMobile to following a report from South Korea, Samsung has already agreed with the supplier of fingerprint sensors, the Chinese company Aegis Technology.
Taking into account Samsung new strategy of endowing its mid-range devices with more technology, it is quite possible that the Galaxy A (2019) series includes a fingerprint sensor integrated into the screen.
The majority of Chinese manufacturers that already have devices with fingerprint sensors based on screens have used the optical type and not the ultrasonic.
The optical sensors work by illuminating the screen so that the light is reflected on the finger. In this way, the sensor captures an image and using different algorithms, is able to detect the unique patterns of each fingerprint.
The ultrasonic sensors, on the other hand, use ultrasounds to create a 3D image of the fingerprint and thanks to this they are more precise and safe. It is expected that the Galaxy S10 will incorporate Qualcomm’s advanced ultrasonic sensor.
In any case, it is not clear which models of the Galaxy A series will receive the in-display fingerprint sensor next year nor the date on which we will see them. Normally Samsung launches new Galaxy A phones about a month before its flagship Galaxy S, so, if they continue this roadmap, it will be a Galaxy A device, and not the Galaxy S10, Samsung’s first smartphone with in-display fingerprint sensor.
