Whether placed on the back, side, or within the display, users of different phones will find unlocking the screen more comfortable with various fingerprint sensor placements. Each position has its own advantages, but some believe that in-display sensors need remarkable improvements and cutting-edge technology.
In the competition against other fingerprint sensors in terms of speed and reliability, in-display sensors have lagged behind. However, this might change soon. Qualcomm, famous for the Snapdragon chipset used in most premium Android phones, has introduced the second generation of in-display fingerprint sensor technology, officially named 3D Sonic Sensor Gen 2.
The 3D Sonic Sensor Gen 2 measures 8mm x 8mm – slightly larger than the 4mm x 9mm size of the first generation. It appears to also collect data 1.7 times faster than before, resulting in a 50% speed boost compared to the first version.
Overall, it seems that the use of this second-generation in-display fingerprint sensor could address many existing issues from the first version.
So, which device will be the first to feature the 3D Sonic Sensor Gen 2? Qualcomm only states that the 3D Sonic Sensor Gen 2 'is expected to debut on mobile devices in early 2021,' so it's unclear which phone will adopt this new technology. However, it appears that the Samsung Galaxy S21, set to launch on January 14th, might be a candidate.

Afterwards, users will get to experience the new fingerprint sensor on Oppo Find X3, OnePlus 9, and several other high-end phones launching this year. It may not appear on Xiaomi Mi 11 or Vivo X60 since they haven't been globally released but are available in China. If these two phones feature the 3D Sonic Sensor Gen 2, Qualcomm made no such announcement at the recent CES 2021 event.
