Around July last year when Corning announced the Gorilla Glass Victus, speculations were rife that the technology will feature on the Galaxy Note 20 first. Indeed, the Samsung Galaxy Note 20 was launched with the latest screen protection technology. The same scenario is about to play out with the Galaxy S21.  Qualcomm has officially announced the latest version of its ultrasonic in-display fingerprint sensor dubbed 3D Sonic Sensor Gen 2.

The new technology looks to improve on the original model in several ways. It also offers a larger surface area for the sensor as well as faster processing, making it possible to deploy the sensor to unlock phones even quicker.

According to Qualcomm, the new 3D Sonic Sensor Gen 2 measures 8mm x 8mm as against the 4mm x 9mm surface area of the first-generation model. This means users get up to 77 percent more surface area. On usage, the wider surface area means it’ll be easier to accurately place your finger on the sensor. It also allows the sensor to collect more data with each scan. When the larger sensor is combined with faster processing, Qualcomm promises that scanning a fingerprint to unlock a phone will go 50 percent faster with the 3D Sonic Sensor Gen 2.

As a reminder, Qualcomm’s first-generation ultrasonic sensor known as 3D Sonic Sensor made its debut in the Galaxy S10 flagship smartphone lineup in 2018. At the time, nearly every other in-display reader used an optical scanner, which was said to be slower and less reliable than the new ultrasonic one.

The sensor, however, encountered several issues, including a highly problematic security flaw that caused the readers to unlock phones with almost any fingerprint when used with some screen protectors. Samsung would later fix this issue through a software update.

Later in 2019, Qualcomm announced the 3D Sonic Max which happens to be just a much larger version of the first-gen sensor with a 20mm x 30mm surface area.

Qualcomm disclosed that the first phones to feature that new 3D Sonic Sensor Gen 2 should be available in “early 2021.” The company left out any specific release details but there are speculations that it will be on the Galaxy S21 which is expected to launch on January 14.

Just yesterday we saw what Mediatek had in store for us for 2015. Now, we have a new image which shows off what Qualcomm has planned for 2015. The image reveals details about the new Snapdragon 820, Snapdragon 815 and the other mid-range SoCs from the 600 series.

The most awaited processor this year is none other than the mighty Snapdragon 820! According to the leakster, this new64-bit SoC will be feature eight TS2 cores making it an octa-core beast. The leakster didn’t reveal the clock speeds. Further, this new SoC will come with Adreno 530 GPU and LPDDR4 RAM. It will support MDM9X55 LTE-A Category 10 networks and will use the advanced Samsung / GF ‘s 14nm FinFet process.

Coming to the next SoC i.e. the Snapdragon 815, it will be an octa-core SoC with four TS1i + four TS1 cores based on ARM’s big.LITTLE architecture. It will use the 20 nm process. The SoC will feature Adreno 450 and LPDDR4 RAM. It will support the high speed MDM9X55 LTE-A Cat10 network band.

The next three are mid-range offerings from Qualcomm. The Snapdragon 629 and 625 will feature eight cores with Adreno 418 GPU and LPDDR4 1600 MHz RAM. The processor will use a 20nm HKMG process by Samsung/ GF. The two along with Snapdragon 620 will support MDM9X45 LTE-A Cat. 10 networks. The Snapdragon 620 will be based on Qualcomm’s Taipan architecture with four cores clocked between 2.0 ~ 2.5 GHz. This one too will feature Adreno 418 GPU but supports the LPDDR3 933 RAM.

Finally, the Snapdragon 616 will feature eight Cortex A53 cores clocked between 1.8Ghz to 2.2Ghz. It will be built upon a 28nm HKMG process from SMIC and will feature Adreno 408 GPU and support LTE-A Cat. 6 networks.

Overall, it looks like Qualcomm has an advanced SoC lineup this year and it would be interesting to see the performance of these ultra fast processors in real life.

Thanks for the tip!
