Nokia 9 PureView Fingerprint Sensor Is Fooled by Chewing Gum

The brand new Nokia flagship with five camera modules looks pretty promising but has several significant weaknesses. Recently, it shocked the world with dangerous security flaw related to its onscreen fingerprint sensor that is tricked by non-registered patterns of other fingers and even various items such as coins or gloves.

Users noticed the first issue right after the launch. Then, Nokia’s scanner had too low sensitivity and didn’t recognize the owners’ fingerprints often.

HMD Global responded to this problem with a patch dated by 19 April. The update improved the scanner’s sensitivity and really helped people to interact with their smartphones. Too much.

As for now, the PureView has an extremely responsive sensor that recognizes not only fingerprints of owners but also other prints and material objects, e.g. chewing gum packs, coins, gloves, etc.

The problem was spotted by Twitter user Decoded Pixel. He posted a video where his Nokia 9 is unlocked with two different fingers and chewing gum
