Facial recognition security is a top modern technology in today's smartphone market, featured in models like iPhone X, Samsung Galaxy Note 8, Galaxy S8 and S8 Plus, Oppo F5, and Vivo V7 Plus. Notably, the technology in the Note 8 and iPhone X is considered to offer higher security.
But between the iPhone X and Samsung Galaxy Note 8, which smartphone's facial recognition technology provides better security? Let's find out with Mytour.
Differences in Facial Recognition Security Technology between iPhone X and Samsung Galaxy Note 8/S8/S8 Plus
Although both smartphones utilize facial recognition technology, they operate based on different technologies.
The iPhone X's Face ID technology utilizes the TrueDepth camera to project 30,000 dots onto the face and analyze them, creating a 'depth map' and 'infrared image' to generate user facial data.

Face ID on iPhone X
The facial recognition technology on the Samsung Galaxy Note 8 and S8/S8 Plus is based on a regular camera and an iris scanner.

Facial recognition on the 2017 Galaxy models mainly relies on the iris scanner
Therefore, in terms of technology, the iPhone X's Face ID is significantly more advanced and comprehensive than the facial recognition of the Note 8.
Which has better facial recognition feature, iPhone X or Note 8?
To conclude, let's compare various aspects of facial unlocking, specifically:
- Unlocking speed with facial recognition
The iPhone X often unlocks faster than the Note 8 or S8 and S8 Plus by about one second, especially in low light conditions, where the gap widens.
However, in bright outdoor conditions, the Samsung Galaxy S8 tends to be more sensitive compared to the iPhone X.
- Success rate of unlocking
The Note 8 tablet and S8/S8 Plus smartphones rely primarily on an iris scanner for security. Therefore, failing to look directly at the infrared camera often leads to unlock failures, particularly in dark settings. In such cases, the rear fingerprint sensor is a more reliable alternative.
Meanwhile, the iPhone X's TrueDepth camera is highly sensitive, quickly unlocking in any environment, especially in low light or darkness.
Additionally, sometimes you don't even need to face the iPhone X directly; a slight tilt of your face can easily unlock the screen.
- Security capability
This refers to how easily others can deceive your face recognition feature with tricks.
The Note 8 and Galaxy S8/S8 Plus have not been very convincing as they can be unlocked with just a photograph.
However, to date, except for BKAV's 3D mask fooling the iPhone X's Face ID, there's no information indicating that the iPhone X's facial recognition has been bypassed.
Conclusion: Despite both being modern features, the iPhone X surpasses in terms of sensitivity and safety features of facial recognition security.
Currently, the market price of the iPhone X is starting from 30 million VND, while the Galaxy Note 8 starts from 20 million VND (imported price).
