The missing Zepp OS 6 launcher is finally reaching Amazfit T-Rex 3

Zepp Health is rolling out the redesigned Zepp OS 6 launcher to the T-Rex 3 family after leaving it out of the original software upgrade. Firmware 6.6.14.3 also adds new lock controls, map improvements and better pace accuracy.

The launcher Amazfit held back is finally here

The T-Rex 3 family moved onto Zepp OS 6 months ago, but one of the most obvious parts of the new operating system was deliberately left behind. The watches received the new operating system but not the Launcher 2.0 interface.

That was not a hardware limitation. As I explained back in August when looking at the missing Zepp OS 6 launcher, Zepp Health had deliberately paused its rollout after getting feedback from users who preferred the old navigation system, particularly the horizontal widgets available from the watch face.

Launcher 2.0 rearranges that basic navigation. Swipe right from the watch face and you now go directly to the Workout List, while swiping down opens Quick Access for system controls and notifications. A double press of the UP button opens Control Center, giving the physical buttons a bigger role in moving around the watch.

That last part arguably makes more sense on the T-Rex than it does on something like the Balance series. These are outdoor watches with chunky physical buttons, so being able to move through more of the interface without relying on the touchscreen is useful when wearing gloves, running in rain or simply during a workout.

It does not mean everyone will prefer the change. The original hesitation over Launcher 2.0 came from genuine differences in how people use their watches, and the new layout still replaces some of the old swipe behaviour rather than simply adding another option. It would be even better if Zepp Health eventually allowed users to customise those directions.

There is quite a bit more in 6.6.14.3

The update is not just an interface refresh. Device Lock now gets an Auto Relock option, while users can assign “Lock Device Once” to a long press of the SEL/DOWN button. Touch Lock during workouts also gains a slide-to-unlock method, which becomes the default way of getting back into the screen.

There is also now a Restore Defaults option inside individual workout settings. Theater Mode has been tweaked as well. It can now automatically adjust brightness based on ambient light when the screen wakes, and you can set how long the mode should remain active.

Navigation gets a couple of changes too. Road rendering on maps has been improved, while direction arrows can now appear along a route at more map scales. For runners, Zepp Health also says pace accuracy has been improved when using GPS Automatic Mode.

A better fit for the T-Rex hardware

The interesting part of this update is not really the version number. It is that Zepp Health has gone back to a software feature it deliberately held off releasing and has now decided the T-Rex line should get it after all.

Zepp Health describes the new launcher as a more consistent foundation across Amazfit watches, rather than something tied to one particular product family. The current Zepp OS 6 overview now lists the T-Rex 3, T-Rex 3 Pro and T-Rex Ultra 2 among the supported devices.

Whether the new navigation is actually better will come down to preference. But on a button-heavy outdoor watch, a launcher designed to work more comfortably without constant touchscreen input has a stronger case than it did on some of Amazfit’s more lifestyle-focused models.
