Nokia 9 buggy update lets anyone bypass fingerprint scanner with a pack of gum

Nokia 9 buggy update lets anyone bypass fingerprint scanner with a pack of gum (Mobile Security)

A buggy update for Nokia 9 PureView handsets has apparently impacted the smartphone model's in-screen fingerprint scanner, which can now be bypassed using unregistered fingerprints or even with something as banale as a pack of gum. The update was meant to improve the phone's in-screen fingerprint scanner module --so that users won't have to press their fingers too hard on the screen before the phone unlocks-- yet it had the exact opposite effect the company hoped for. While initially, the reported issues appeared to be new, a video recorded by another user showed the same problem (unlocking phones with unregistered fingerprints) even before the v4.22 update, meaning that the update just made the unlocking bug worse than it already was. This means that rolling back the faulty v4.22 firmware update, or waiting on v4.21, won't fix the fingerprint scanner problems, as even before this patch, the scanner appeared to have a pretty high false negatives rate, allowing strangers to bypass the phone's screenlock. This incident isn't Nokia's first problematic firmware update either.
