A few days ago, The Sun reported a major flaw with the fingerprint recognition system of the Galaxy S10 and the Galaxy Note 10 that lets anyone unlock these devices. Samsung immediately made an investigation and found that if a user tries to register a fingerprint on these devices with a silicone screen protector applied, the device registers the texture on the inside of the screen protector as the fingerprint, instead of the actual fingerprint. And when anyone (whose fingerprint isn’t registered in the device) tries to unlock the smartphone, the device scans the inner texture of the screen protector and unlocks the device.
After Samsung’s investigation, the brand announced that it would soon send a software update to these devices to fix the issue. Well, that update is currently being rolled out to all the affected smartphones in Korea. Samsung is advising its users to delete previous fingerprints from their smartphones after updating the device. Unfortunately, the update for the fix is yet to reach devices in the markets outside Korea. I hope Samsung rolls out the update to other markets soon. If not, I am sure that the security issue will impact device sales.
Sales figures aside, all major banks around the world have started blacklisting the Galaxy S10 and the Galaxy Note 10 from their banking applications. So, this is a major issue for people who own the affected smartphones. That being said, you don’t have to worry about your device giving access to anyone unless you have registered fingerprint with a silicone screen protector applied. For those who have registered fingerprints with the silicone protector applied, please remove the screen protector, and re-register your fingerprints to save your device from the security flaw. Until Samsung rolls out the update for the fix, it is not advisable to register fingerprints on these devices with a silicone screen protector applied.
