Qualcomm’s Snapdragon 855-based in-display fingerprint scanner makes use of a high-frequency ultrasonic sound that users cannot hear. The sound waves map out the ridges, pores and other landmarks of the finger.
The ultrasonic sensor for fingerprint recognition can detect blood flow within the finger and actually prevent hackers from spoofing the device with a photo or mold, according to Qualcomm.
However, some Galaxy S10 users have taken to the online community to express inconveniences caused by multiple failures of the fingerprint scanner, especially when making financial transactions via mobile apps.
“There can be many occasions where users find the fingerprint scanner doesn’t work well, for example, when you are in a dry environment, or when your finger skin is really dry, or when you have a scratch on your fingerprint,” said a Samsung official.
“The accuracy has been improved through the first update of software recently just in one week since the launch, and we will continue providing updates to make the scanner work better.”
Qualcomm Korea said it is aware of the complaints, but declined to elaborate.
