A new public beta has been released by Garmin for the Fenix 7 series, offering a new heart rate tweak and fixes for mapping issues. However, this update disables the ECG feature on the devices. Despite a recent outage, Garmin continues to roll out beta features to improve the user experience. Garmin has provided details on the updates in the beta version, including fixes for mapping and heart rate broadcasting. Users should be aware that installing the latest beta will result in the loss of access to the ECG feature. Garmin has confirmed that the ECG feature will be re-enabled in future beta updates. It is essential for users to stay informed about these changes, especially if they rely on the ECG feature for medical purposes. In addition to the beta update, Garmin has expanded ECG support to certain European and Australian models.
