Apple’s WatchOS 5.1 update is bricking some Apple Watch devices : Straight after its Brooklyn event earlier today, Apple began rolling the WatchOS 5.1 update to its range of Apple Watches. The software activates the ECG feature on Series 4 models in the US and also introduces support for 70 new emojis and Group FaceTime but, from the looks of things, not everyone is having luck with the new software.
Apple is yet to pull the new WatchOS 5.1 update so it’s unclear at this point how many users are affected by the issue. However, those of you who are will likely need to contact Apple Support and request a replacement device. Furthermore, users who are yet to update may want to hold off on the new software version until Apple corrects the problem.
