Apple has released watchOS 7.4 with the ability to unlock an iPhone with Face ID while the user is wearing a mask, option to classify Bluetooth devices, support for streaming audio and video content from Apple Fitness+ workouts to AirPlay 2 devices, and ECG and irregular heart rhythm notifications support in Australia and Vietnam.
What’s new in watchOS 7.4?
The most important feature in this update is the ability to unlock iPhone X or later models using an Apple Watch, while wearing a mask. This feature works in tandem with iOS 14.5, and removes the need to take off your mask or entering a passcode just to unlock your iPhone. However, to use Face ID for App Store, Apple Pay, and third-party apps such as banking, users still have to enter a passcode or take off their mask to use authentication. While this is not as convenient as a fingerprint scanner in the current pandemic, it is still a step up from having to enter a passcode.
Other updates include the ability to classify Bluetooth device type in Settings, audio and video streaming from Apple Fitness+ workouts to AirPlay 2 enabled TVs or set-top boxes, and ECG and irregular heart rhythm support in Australia and Vietnam.
Here are the complete release notes from Apple:
