Amazfit has started pushing out a major software update to its rugged outdoor smartwatches. Firmware version 6.6.14.3 is now making its way to the Amazfit T-Rex 3, T-Rex 3 Pro, and T-Rex Ultra 2, bringing a fresh interface layout, better screen lock controls, and sharper navigation tools.
A Fresh Way to Navigate Your Watch
The biggest visual change in this update is the arrival of a brand-new Launcher designed to make daily navigation faster. Swiping right from the main watch face now jumps straight into your Workout List, while swiping down opens a redesigned Quick Access menu that combines system controls and notifications in one place.
Amazfit has also added a handy hardware shortcut. If you want to open the Control Center without touching the screen, you can simply double-press the physical UP button.
Smarter Screen Locks and Workout Controls
Accidental screen touches are a common headache during outdoor adventures, and version 6.6.14.3 addresses this with several new lock options:
-
Auto Relock: Device Lock now includes an automatic relock mode so your watch stays secure after you finish checking it.
-
Quick Lock Shortcut: You can assign a “Lock Device Once” action to a long press of the SEL/DOWN button by heading into Settings > Preferences > Shortcut Keys > Long Press SEL/DOWN.
-
Slide to Unlock: During workouts, Touch Lock now supports a slide gesture to unlock the screen, offering an alternative to holding down a physical button.
For athletes who like to tweak their tracking screens and alerts, Amazfit has also added a Restore Defaults option inside individual Workout Settings. If your custom layout for a sport like Outdoor Running gets too messy, you can now reset that specific activity back to its factory state without wiping the rest of the watch.
Better Maps, GPS Accuracy, and Theater Mode
Alongside the new features, the update polishes several core tools that outdoor users rely on. Offline maps now feature cleaner road rendering, and route direction arrows remain visible across more zoom levels during active navigation.
Runners and hikers using GPS Automatic Mode should also notice more accurate real-time pace tracking. Meanwhile, Theater Mode has been upgraded so you can set a specific timer for how long it stays active, and the display will now automatically adjust its brightness based on the surrounding light whenever the screen wakes up. The update wraps up with general bug fixes to improve overall stability.
When to Expect the Update
Amazfit is releasing firmware 6.6.14.3 in stages rather than all at once. A portion of T-Rex 3, T-Rex 3 Pro, and T-Rex Ultra 2 owners can download it today, while everyone else should see the prompt arrive through the Zepp app over the next few days.
