Samsung Vietnam officially launched the fingerprint security update for Galaxy S10 and Note 10

About two weeks ago, a woman in England discovered a major security flaw on her Galaxy S10 . After applying a screen protector, her smartphone could be opened with her husband’s fingerprint, although he did not install the fingerprint in the device. To make matters worse, many banks have closed applications for the S10 and Note 10 models (both have ultrasonic fingerprint sensors) for security reasons.

According to Samsung, this is a software bug and can be easily fixed. This morning (October 25), some S10 and Note 10 devices in Vietnam have received an update to fix this bug, with a capacity of just over 4Mb. As explained in the update, the ultrasonic fingerprint sensor has been ‘tricked’ by the fingerprints found on the low-quality screen assembly, making it seem like a user’s fingerprint.

The company recommends that users install this update immediately, then remove the screen protector and install the fingerprint. If the user is pasting a patch, it is very likely that the device will not be able to read the fingerprint after the update, and the company also said that users should not use them because of possible error with the sensor in the future, especially inexpensive ones with completely flat internal surfaces.
