The Nokia 9 PureView's fingerprint sensor can apparently be unlocked by just about everything - including chewing gum

The Nokia 9 PureView's in-display fingerprint reader has been the subject of many a debate, and the company has sent out OTAs that were supposed to improve it. A new video, however, shows a Nokia 9 PureView being unlocked by an unregistered fingerprint, and a packet of chewing gum afterwards. And no, we're not making this up.

The Nokia 9 PureView was released a while ago and we had high hopes for it, as it was the first actual Nokia flagship and did something new with its penta-lens camera setup. As is becoming the tone for most of the new Nokia phones, however, it's turned out that the Nokia 9 PureView has quite a lot of issues. Over the past month, there have been reports about instability with the device's camera app—unacceptable, considering cameras are the phone's biggest selling point. There have also been reports of poor battery life. The newest issue on the block, however, has to do with the phone's fingerprint reader.

Like with most new flagships, the Nokia 9 uses an in-display optical fingerprint reader. Sadly, optical fingerprint readers are far from the most reliable, and it's starting to show. Users reported issues with the sensor and Nokia pushed out an OTA that was supposed to fix it. It's apparently just made things worse, though.

While, previously, users may have found it hard for the fingerprint reader to recognize their prints, the update makes sure that the fingerprint reader reads everything, from an unregistered fingerprint to...a packet of chewing gum.

We're not the biggest fans of in-display fingerprint readers, and this is a prime example of why. Regular capacitive sensors are still the most reliable, and we're not even sure why the new in-display technology exists at all, since it's mostly a step backward.

Hopefully, HMD Global does something about this, as it poses a huge security risk to users of the Nokia 9 PureView.
