The facial ID technology is not 100% secure, even Apple has suggested that.
This happening was posted on popular website Reddit on November 3, 2017, the day the flagship phone went on sale worldwide.
"We are not twins. He is five years younger than me,” the older brother and owner of the iPhone X said.
It’s learnt that they both wear similar glasses. When his younger brother tries to unlock the phone without his glasses on, it doesn’t work. But when he slips his glasses back on, the iPhone unlocks.
Although Apple has expressed confidence in the facial ID technology, saying there is a one in a million chance that another person can unlock the face ID that isn’t his, they have also acknowledged that face ID may be less secure when it comes to siblings and twins with similar facial features.
So except you don’t have a problem with your blood brother or sister unlocking your phone, you may want to stick with other security options like the Touch ID.
In other news relating to the iPhone X, it was reported on Friday, that $370, 000 worth of the device got stolen by robbers in the US.
