Apple today seeded the fourth beta of an upcoming watchOS 4 update to developers for testing purposes, four days after releasing the third watchOS 4.1 beta and a month after releasing the new watchOS 4 operating system to the public.
Once the proper configuration profile has been installed from the Apple Developer Center, the new watchOS 4 beta can be downloaded through the dedicated Apple Watch app on the iPhone by going to General --> Software update.
To install the update, the Apple Watch needs to have at least 50 percent battery, it must be placed on the charger, and it has to be in range of the iPhone.
watchOS 4.1 brings support for streaming Apple Music content directly to the Apple Watch Series 3 over LTE and it introduces a new Radio app with access to Beats 1 and other Apple Music radio stations.
The Music app on the watch looks the same, offering up access to the Music Library, recently played songs, playlists, and Apple Music mixes, but now all Apple Music content can be streamed over an LTE connection and doesn't need to be downloaded to the device. watchOS 4.1 also adds a new Wi-Fi toggle for turning off Wi-Fi to force the Apple Watch Series 3 to use LTE and it displays the Wi-Fi SSID so users can see the Wi-Fi Network an Apple Watch is connected to.
Support for Apple Music streaming appears to be the main feature in the new watchOS 4.1 update, but Apple is also introducing a range of new Unicode 10 emoji characters that include vomiting face, head exploding, mermaid, zombie, hedgehog, fairy, broccoli, and more.
Apple says the watchOS 4 update addresses a serious vulnerability in the WPA2 Wi-Fi standard that protects many modern Wi-Fi networks.
watchOS 4 is a significant refresh of the watchOS operating system introducing new watch faces, including a personalized Siri face, improvements to the Workout app, support for integration with gym equipment, an Apple News app, a vertical Dock, and a new Flashlight feature in the Control Center.
