Ability to unlock on Apple Watch
On the 26th (local time), Apple reported a bug on the support page, saying that the "unlock with Apple Watch" function may not work properly on the iPhone 13.
With iOS 14.5 and watchOS 7.4, which went on sale in April, iPhones with Face ID and Apple Watch Series 3 and later combinations can use the Apple Watch to lock the iPhone even when the user is wearing a mask. It can be canceled. However, this unlock function may not work properly in combination with the iPhone 13.
The company has already confirmed the problem and plans to fix it in a future software update. If something goes wrong, we recommend turning off the unlock feature on your Apple Watch and using passcode unlocking.
