Apple Releases watchOS 5.3 With Walkie-Talkie Bug Fix, ECG Support for Canada and Singapore

[steven36]

Apple today released watchOS 5.3, the seventh update to the watchOS 5 operating system that runs on modern Apple Watch models. watchOS 5.3 comes more than a month after the launch of watchOS 5.2.1, a minor update that expanded ECG availability.

 

watchOS 5.3 can be downloaded for free through the dedicated Apple Watch app on the iPhone by going to General -> Software Update. To install the new software, the Apple Watch needs to have at least 50 percent battery, it needs to be placed on a charger, and it needs to be in range of the iPhone.

 

No new features were discovered in watchOS 5.3 during the beta testing process, but according to Apple's iOS 12.4 release notes, the new update, along with iOS 12.4, fixes a major bug in the Walkie-Talkie app that could allow it to be used to spy on people and it once again makes the Walkie-Talkie app accessible.

The watchOS 5.3 update also brings ECG support and irregular heart rhythm notifications to Apple Watch Series 4 owners in both Canada and Singapore. The ECG feature's launch in Canada comes a few months after Apple confirmed that it was working to bring ECG functionality to the Apple Watch in Canada "as quickly as possible."

Health Canada initially approved the ECG app and irregular heart rhythm notifications on Apple Watch Series 4 in May. ECG capabilities are now available in more than 25 countries, following the feature's rollout to many European countries earlier this year. A list of countries where ECG functionality is available can be found on Apple's Apple Watch feature availability website.

Apple's full watchOS 5.3 release notes:

This update includes new features, improvements and bug fixes and is recommended for all users:
- Provides important security updates including a fix for the Walkie-Talkie app
- ECG app on Apple Watch Series 4 now available in Canada and Singapore
- Irregular heart rhythm notifications now available in Canada and Singapore

watchOS 5.3 may be one of the final updates to the watchOS 5 operating system as Apple shifts its focus to watchOS 6, which is currently being beta tested ahead of a planned fall release.

Apple's Walkie-Talkie Apple Watch App Works Again Following iOS 12.4 and watchOS 5.3 Release

 

 

Nearly two weeks ago, Apple disabled the Walkie-Talkie app on the Apple Watch after discovering a bug that could allow the feature to be used to eavesdrop on others.

At the time, Apple said that it had just learned of the vulnerability and was taking the app offline while working on a fix. That fix is ready today in both iOS 12.4 and watchOS 5.3, which means the Walkie-Talkie app is once again available for use.

 

When disabling the Walkie-Talkie app, Apple didn't pull it off of Apple Watches, leaving the app intact but rendering it non-functional. Today's software updates fix the vulnerability and bring the app back online.

 

Walkie-Talkie was one of the headline features in watchOS 5, released last September. Walkie-Talkie is designed to allow users to communicate with one another using a push to talk function, similar to a real walkie-talkie.

Apple said that it did not believe that the vulnerability in Walkie-Talkie was exploited to spy on anyone, but disabled the feature out of an abundance of caution.

We were just made aware of a vulnerability related to the Walkie-Talkie app on the Apple Watch and have disabled the function as we quickly fix the issue. We apologize to our customers for the inconvenience and will restore the functionality as soon as possible.

Although we are not aware of any use of the vulnerability against a customer and specific conditions and sequences of events are required to exploit it, we take the security and privacy of our customers extremely seriously. We concluded that disabling the app was the right course of action as this bug could allow someone to listen through another customer's iPhone without consent. We apologize again for this issue and the inconvenience.

Apple was quick to take down the Walkie-Talkie app as it suffered from another eavesdropping bug recently that received major media attention. A serious Group FaceTime bug was discovered back in January, and when exploited, it allowed callers to hear a user's audio even when the call had not been accepted.

In that situation, Apple did not remove the Group FaceTime feature until it had been publicized, despite the person who discovered the bug having submitted a report days before. Apple fixed the Group FaceTime bug after a week and a half, addressing it in iOS 12.1.4.
