Garmin has officially launched a fresh beta software update, version 21.24, targeting its premium lineup of rugged smartwatches. This release is specifically designed for the Fenix 8, Fenix 8 Pro, Enduro 3, Quatix 8, and Tactix 8 series. While beta updates often come packed with experimental features, this particular version focuses on refining the user experience by eliminating a frustrating stability bug.
Note: This Beta Software 21.24 Disables ECG, Aviation, and Dive features.Â
Critical Fix for Garmin Messenger Integration
- Fixed a possible crash when pairing to Messenger after clearing settings.
The primary highlight of this 21.24 build is a targeted patch for the Garmin Messenger app. Previously, users reported an intermittent system crash occurring during the pairing process, specifically after the watch settings had been cleared. This update resolves the conflict, ensuring that users can reconnect their communication tools seamlessly without the device rebooting or freezing.
It is a minor but essential “quality of life” fix for those who rely on Garmin’s satellite and LTE messaging ecosystem for off-grid communication.
How to Install the Beta Update Manually
Unlike standard public rollouts that arrive automatically over several days, beta testers can jump to the front of the line by manually triggering the download. If your device is enrolled in the Garmin Beta Program, you can pull the update directly over Wi-Fi.
To get started, navigate through your watch interface using these steps:
-
Hold the Menu button.
