Amazfit is actively deploying a significant firmware update, version 3.3.4.1, specifically designed for its rugged Amazfit T-Rex 3 Pro smartwatch. This release introduces a host of new features and crucial stability improvements, enhancing both daily usability and specialized sports tracking.
New Screenshot Capture Functionality

One of the most user-friendly additions in this update is the ability to easily capture a screenshot of the watch face. Users can now simultaneously press the SEL (Select) and BACK buttons to capture the current screen. These captured images are then automatically transferred and saved directly to the photo album on the connected smartphone, making it simple to share or reference watch data and settings.
Advanced Data for Recreational Diving

For users engaging in underwater activities, the update brings a notable improvement to the Recreational Diving mode. The “Go page” now features dedicated icons for “No-Fly” and “Gas,” along with their associated data. This enhancement provides divers with more comprehensive, immediate, and clearer information directly on the watch screen, which is vital for post-dive safety planning and tracking essential resources.
Expanded Outdoor Sports Navigation Support
Recognizing the adventurous spirit of the T-Rex Pro series, Amazfit has broadened the watch’s navigation capabilities. This firmware update adds navigation support for a greater number of outdoor sports. This means users can now benefit from detailed route guidance and location tracking across an expanded array of activities, improving safety and exploration for outdoor enthusiasts.
Enhanced Sleep Management Tools
The firmware upgrade also offers users more control over their sleep tracking data. New options have been implemented to allow users to delete and edit nap records. This added flexibility ensures that sleep data is more accurate and personalized, catering to individuals who have non-standard or varied sleep schedules and need to manage their sleep logs precisely.
Helio Strap Compatibility for Accurate Training

In a move to improve the accuracy of workout metrics, the T-Rex 3 Pro now includes support for external heart rate monitoring. Specifically, the watch can now utilize the Helio Strap as a heart rate sensor during workouts. Connecting this dedicated strap allows for the collection of more precise and reliable training data, which is essential for athletes focused on optimizing their performance and intensity zones.
General Stability Improvements and Phased Rollout
As is standard with major firmware releases, version 3.3.4.1 also incorporates fixes for known issues and delivers improved overall system stability and smoothness. These general enhancements ensure a more reliable and responsive user experience. Users need to note that this update is being deployed in a phased manner. While some users have already received the notification and installed the update, others may need to wait a few days as the rollout gradually reaches all eligible devices.
