Amazfit T-Rex 3 Pro Stumbles at $399 as Swim Tracking and Screen Unlock Glitch

Summary
$399 Amazfit T-Rex 3 Pro earned a middling verdict after repeated misses in pool swims, slow GPS acquisition and unreliable screen unlocking during workouts.
In multiple 2,500-meter pool sessions, the watch never logged more than 2,000 meters, while GPS sometimes took up to 5 minutes to lock before runs and rides.
Once connected, outdoor distance tracking was accurate, matching known route lengths and a rival watch, and battery life stood out with rated endurance of 17 to 25 days.
A screen-unlock bug left one run recording for 34 hours until the battery died, and that phantom workout kept resurfacing in later post-exercise summaries even after history was cleared.
The review concluded the rugged multisport watch is competent but hard to recommend given the glitches, especially when buyers are paying hundreds of dollars for reliability.
