Garmin Rolls Out Beta Version 28.07 for Fenix 7 and Related Smartwatches

Garmin has advanced its latest software testing phase by pushing out Beta Version 28.07 to a wide range of premium wearables, covering both standard and Pro variants such as the Fenix 7 Pro Sapphire Solar. Unlike automatic rollouts, this specific firmware requires a manual download by navigating through the main menu to Settings, System and Software Update, and selecting the 'Check for Updates' option.

This new beta build directly targets two persistent glitches found in the preceding v28.02 software. Specifically, it resolves a critical bug that triggered random device shutdowns when the wearable paired with a bike shifter—affecting select Enduro 2, Epix, Fenix 7, and Quatix 7 models. Additionally, the patch fixes an issue where the watch would still enter sleep mode despite users manually turning off the setting entirely.

According to the company's release notes, ECG functionality remains disabled in this build, suggesting that engineers will likely issue further v28.xx beta revisions before pushing a stable public update. Should you download it? As a pre-release firmware meant for manual installation, it is best suited for users comfortable troubleshooting minor software bugs rather than those seeking daily operational stability.
