Huawei introduced the Watch GT4 about two months ago with HarmonyOS 4 out of the box. Today the units started receiving an update that streamlines two main features: sleep tracking and cycle calendar.

The update version is 4.0.0.122 (C00M02) and is 45.90 MB in size. Users worldwide should receive the package, which can be found in the Huawei Health app -> Devices -> Huawei Watch GT4 -> Firmware Update.

The Watch GT4 not only tracks sleep but also nighttime breathing, but the reports don’t say much, as we found in our review, so hopefully this has been fixed.

The Cycle Calendar app is a tab under the Health tab and eliminates the need for a separate app on your phone. Once again we don’t know what exactly has been fixed, but we can only assume that there have been improvements in the backend that are responsible for better cycle prediction based on the user’s biometric data.
