A notable security feature of Galaxy S8 is its facial scan that will allow its owners to unlock their devices through face recognition software. Although advertisements show how the feature is stunning some people don't agree with it.

It can be remembered that Galaxy S8 and Galaxy S8 Plus are already available and are available already for preorder last March 30. The devices will soon be released on April 21st but several issues were already spreading that the devices' security feature may not as good as one may think.

One of the issues that have been revealed was mentioned by CNBC, saying that the advertise face recognition software could easily be tricked. A video demonstration has been done to trick the facial recognition software.

It shows that the facial recognition software was being fooled by an image of the device's owner. A phone was held up to the facial scanner that contains an image of the owner on its display, after few seconds the device's sensor was led to believe that it is looking at its owner then subsequently unlocks itself.

Another issue that The Verge has recently reported was that it won't give a legal protection so much as a passcode can quoting The Fifth Amendment that protects people from incriminating themselves. Password or codes are considered as "testimonial" evidence. It means that a person may refuse to give up their PIN because in doing so it would only mean that he is answering a question based on the contents of his thoughts, not providing a physical piece of evidence.

While when a phone is held up to a face or eye would not be a "testimonial act" as it does not require the owner or perhaps the suspect to provide information that is on his mind, Jeffrey Welty said. However, this isn't a cut-and-dried issue as there are also certain cases that courts ordered to unlock a device with a code like if a police already knew what is on the device and the person in question is the owner.

Until then, there are still a lot of issues on the security feature of Galaxy S8. From the sources and other reports, it is at most an advice for those owners to rather use a password or passcode better yet than a Touch ID or facial recognition to be able to be protected legally or might as well delete those data.
