If you’re an owner of the rugged Amazfit T-Rex 3 Pro, get ready for a pleasant surprise. A significant new software update has begun its global rollout, packing a handful of highly-requested features and quality-of-life improvements that make this durable smartwatch even more capable.
This latest release, version 3.3.4.1, follows the 3.3.1.8 update from early November 2025, which itself focused on route creation and battery optimizations. It seems Amazfit is committed to refining the T-Rex 3 Pro experience well after its launch.
What’s New in Update 3.3.4.1?
This isn't just a minor bug-fix patch. The new firmware introduces several tangible features that users will appreciate in their daily routines and workouts.
- Take Screenshots Directly on Your Wrist: Perhaps the most instantly gratifying new feature is the ability to capture your watch screen. Simply press the SEL and BACK buttons simultaneously, and a screenshot will be saved directly to the photo album on your connected smartphone. It’s perfect for sharing your latest workout stats or a custom watch face with friends.
- Smarter Sleep and Nap Tracking: Accuracy in health metrics is paramount. With this update, users can now edit and delete their nap records. If the automatic tracking picks up a quiet period of reading as a nap, you can easily remove it, leading to a more precise overview of your actual sleep patterns.
- Enhanced Heart Rate Monitoring with Helio Strap: For fitness enthusiasts demanding the most accurate biometric data, the T-Rex 3 Pro now officially supports using the Amazfit Helio Strap as a connected heart rate sensor during workouts. This chest strap is designed to provide more reliable heart rate data than optical wrist sensors during intense, high-movement exercises. You can find the Helio Strap available for purchase, such as this listing on Amazon for $99.00.
- Expanded Navigation and Diving Data: Amazfit has extended its navigation support to more outdoor sports modes, though the specific activities weren't detailed. Furthermore, recreational divers get new data fields on the "Go" page: "No-Fly" time and "Gas" information, crucial for safe dive planning.
As with any substantial update, Amazfit notes that it has also squashed several bugs and enhanced the overall system stability for a smoother user experience.
Rollout Details: How to Get the Update
Software version 3.3.4.1 is being released in phases. Early reports, including one from a user on the 4pda forum who first spotted the rollout, indicate that the update is currently reaching users in the United States.
Typically, Amazfit pushes new updates to regions like the US, Canada, and China first, with a broader global rollout following in the subsequent days or weeks. Don't be alarmed if you don't see it immediately on your device.
When the update is available for your T-Rex 3 Pro, you’ll receive a notification through the Zepp Health app. Simply follow the on-screen instructions to install the new firmware and unlock these new features on your rugged companion.
