A video has emerged showing how the Galaxy S8 facial recognition can be bypassed by a user's photo.

Gadget 360 reported that the video, which was posted by YouTube account iDeviceHelp, sourced by bloggers at Marcianophone just days after Samsung unveiled the Galaxy S8 and its sibling, the Galaxy S8 Plus.

The video shows how a user unlocks the Galaxy S8 device by simply taking another device with the user's selfie image and moving it towards Samsung's newest flagship phone.

Gadget 360 warned that the ease of unlocking the device could pose a concern for users despite the availability of other security options.

"Even though biometric security features have been found to be vulnerable to hackers earlier as well, Samsung has pitched facial recognition along with the iris scanner as secure authentication features that help you enhance the protection of your device. If true, the video could prove the South Korean company wrong," it said.

The Verge suggested that it is possible that Samsung is still currently working on Galaxy S8 facial recognition feature based on cues from the company's previous statements.

Samsung, for instance, has noted that facial scanning is not the most secure form of authentication while adding that the use of fingerprint, iris or a PIN is preferable. The company has ruled out rumors that it will be using facial recognition for Samsung Pay.

The Galaxy S8 phones that were displayed during the New York City event were not the final products. Hence, it is assumed that Samsung could be improving the security option before shipping to the public.

The Galaxy S8 and S8 Plus will be officially released on April 21. Samsung's latest flagship device has attracted a great deal of attention since its launch. Aside from Galaxy S8 facial recognition, some of the much-talked about features of the device are the near-bezel-free design, curved screen, Dexdock, Bixby smart assistant, and more.
