Call handling is more limited than expected. Users report receiving incoming call alerts on the watch, but several say there's no option to actually answer the call, only to silence or reject it. One iPhone user specifically notes they cannot answer calls at all on that platform. This suggests the calling feature, a headline function for this model, works inconsistently depending on phone and firmware, leaving some buyers unable to use it as intended for full hands-free calling.

Build quality and longevity raise concerns for some buyers. One reviewer says the watch is not actually water resistant despite claims, and that their unit fell apart after water exposure, held together only loosely by included glue. Separately, another buyer reports the physical power buttons stopped functioning after just five days of use, and a third commenter references seeing multiple reports of units dying shortly after purchase, pointing to possible durability or quality-control issues.

The companion app and defaults feel restrictive to set up. Multiple users hit friction with the FitCloudPro app: only three sport modes appear (walking, running, mountaineering) with no way to delete or add activities like cycling, and downloading extra watch faces reportedly doesn't work. Separate users also struggled with basic functions, including an alarm that displays on screen without actually sounding, and unclear icons or charging instructions, suggesting documentation and app usability gaps.
