Samsung Galaxy S10 fingerprint sensor slower than Galaxy S9

This time Samsung’s launched to an in-display fingerprint sensor is the only controversial decision. and Report says Samsung Galaxy S10 fingerprint sensor slower than Galaxy S9.

Actually, the only controversial things Samsung has done in the last handful of years have all related to biometric security. Moving the fingerprint sensor to a nonsensical place, and trying to rely on iris scanning were solid blunders in their own right.

And now, we have another attempt: an in-display fingerprint sensor. This isn’t the first we’ve seen also Oneplus, Vivo, Oppo, Xiaomi, Huawei already launched. but it is the first using this type of technology: ultrasonic, using sound waves, rather than optical, which uses a camera.

The ultrasonic fingerprint sensor is better than the optical ones I’ve used, but it is not as fast, accurate or easy to use as a modern capacitive fingerprint sensor. That shouldn’t really come as any surprise, as capacitive sensors are a mature technology while the in-display sensors are still relatively new. But it’s worth making clear. There is no situation in which the ultrasonic fingerprint sensor has been faster or more consistent than the Galaxy S9’s rear-mounted capacitive sensor. That’s incredibly unfortunate.
