New Features in Firmware Version 4.4.2.3

Users who connect third-party speed, power, or cadence sensors will notice that the graph showing the collected data will appear automatically during workouts. Additionally, if the weather information isn’t available at the beginning of a workout, it will not be shown in the workout log within the Zepp app.
Navigation and Activity Updates
Amazfit T-Rex 3 smartwatch users will enjoy two enhancements related to maps. Firstly, the SEL button can now be used to quickly access navigation settings either in the Map app or on workout track pages. Secondly, the default navigation mode in the Map app has changed to “North up.” The change log also mentions improvements for activity reminders, including a fix for unexpected push notifications, along with various minor bug fixes and enhancements.
Availability of the Update
It is still uncertain when all Amazfit T-Rex 3 smartwatch users (currently priced at $249.98 on Amazon) will get the firmware version 4.4.2.3. An update for the T-Rex 3 Pro smartwatch is anticipated to be released soon.
