Despite its best efforts, Samsung decided against using an in-display fingerprint scanner on the Galaxy S9 and Note 9 this year. This was because the company believed the technology was simply not ready. With the Galaxy S10 though, the company is determined to use an in-display fingerprint sensor especially since Chinese OEMs like Oppo and Vivo have already launched multiple phones with an in-display fingerprint scanner.
Samsung’s patience, however, will pay off with the Galaxy S10 as it has seemingly managed to get access to Qualcomm’s best in-display fingerprint sensor. The Korean company will reportedly be using Qualcomm’s third-generation ultrasonic sensor on the Galaxy S10 which is not only more accurate but faster as well.
The Galaxy S10 is likely going to be the first smartphone to hit the market with Qualcomm’s third-generation ultrasound sensor. To ensure that there are no supply issues, Samsung will be working with Qualcomm and GIS to ensure that adequate quantities of the in-display fingerprint sensors are available.
Qualcomm’s in-display fingerprint sensor will not negatively affect the image quality of the display panel since it can operate from the back of the panel. This is unlike existing in-display fingerprint sensors used by Oppo and Vivo which applies a thin film on the bottom half of the display. This film can be easily seen when the display is off and its brought under direct sunlight.
Qualcomm first debuted its ultrasound sensor in 2015, with the second generation sensor making its debut in 2016. The sensor has largely been used by some low-key Chinese OEMs, with Xiaomi only the most renowned smartphone OEM to use the sensor on its Mi 5s.
