Update Announcement
In a recent post on Instagram from Amazfit Germany, it was stated that the T-Rex 3 will be upgraded to Zepp OS 5 “soon.” Zepp OS 5.0 was first introduced with the Balance 2 smartwatch and is also available on the Active 2 (Square). It has recently been made available for the Active 2 (Round), Active 2 Premium, and Bip 6 smartwatches, which currently retails for $79.99 on Amazon.
