OnePlus 7 Pro optical in-display fingerprint sensor easily spoofed, Apple selects acoustic sensing


The OnePlus 7 Pro smartphone’s optical in-display biometric fingerprint sensor can be hacked with some tinfoil and glue, Hot Hardware reports.

YouTube channel Max Tech used the same simple and inexpensive technique it had previously used to spoof the fingerprint sensor in a OnePlus 6T. The same approach did not work on a Samsung Galaxy S10+’s ultrasonic fingerprint sensor. The test involves a piece of hot glue on aluminum foil, which is formed to a fingerprint mold with a wet finger. A squirt of Elmer’s glue on the dried fingerprint mold the fills it in to be applied directly against the sensor when it too is dry.

Max Tech notes the speed of the OnePlus 7 Pro fingerprint sensor is very fast, compared to other smartphones.

2020 iPhones may have full-screen Touch ID

Barclays analysts are predicting the inclusion of acoustic (ultrasonic) fingerprint technology in 2020 iPhones, possibly allowing for full-screen Touch ID, MacRumors reports. The same models are expected to introduce 3D sensing in rear camera modules.

The research note, based on meetings with Apple suppliers, also suggests relatively few design changes for 2019 iPhones other than additional rear camera lenses. 3D Touch will be eliminated, Haptic Touch possible expanded in 2019, and 5G support added in 2020.

Apple was recently granted a patent for in-display acoustic fingerprint technology, and AUO launched a display panel for full-screen optical in-line fingerprint scanning earlier in May.
