A man from Shanghai bought his wife the new gadget soon after it was released last month, but she was shocked to discover it could be unlocked by her teenage son. The man, identified only by his surname Liu, reported the issue to Apple's customer services. He was told it was an isolated case and was due to the fact his wife and son look very similar.

This is the latest of several Chinese cases. Last week, we ran a yarn about a woman from Nanjing discovered her colleague - who is not related to her - was able to unlock her phone using Face ID.

The incidents have led to claims of racism on social media, with some blaming the lack of ethnic diversity in the technology industry. Others accused Apple of only testing Face ID on white people.

This has put Apple on the back foot. It claims to have worked with iPhone users all over the world to ensure the product is accessible to people of different ethnicities.

Cynthia Hogan, Apple's vice president of public policy for the Americas proudly said that Jobs’ Mob worked with participants from around the world to include a representative group of people accounting for gender, age, ethnicity, and other factors.

The company's support page states that the probability that a random person in the population could look at your iPhone X and unlock it using Face ID is approximately one in a million. Unless you have a twin or sibling who looks the same as you. It is also higher for children under the age of 13, because their distinct facial features may not have fully developed, according to Apple.

Apple has been doing its usual “blame the user” and insisting that they must have shared their phones while they were doing the "passcode training" and that the phones may have been essentially "taught" to recognise both faces. Clearly that is bollocks as you don’t usually share your phone with a college when you are password training.

For what it's worth we don’t think that Apple is racist. We just thing it’s software standards have slipped as it made more money and its facial recognition system went out half baked.
