"Samsung Electronics is aware of the case of a fingerprint recognition malfunction on the S10 and will soon release a software patch," the company said in a statement Reuters . The issue was considered serious enough that an online bank in South Korea, KaKaobank, advised owners to turn off fingerprint detection until it fixes fingerprint edges. Screen protectors made of plastic or silicone can prevent this. Therefore, Samsung recommends that buyers use approved protection devices. However, this does not explain why the system allows access to unregistered fingerprints. Therefore, Engadget has asked Samsung for more information.
Samsung communicated to the British publication The Sun that for the first time reported the problem that it was dealing with the problem. Until there is a patch, you could use Samsung's Face Unlocking, but that had its own problems. For the time being, just use a good old code.
