After the recent One UI update, my Galaxy Watch4 is not tracking sleep at all. Sleep data is missing even after wearing the watch properly overnight. Heart rate works, but sleep monitoring completely fails. Tried reboot, reset, and re-pairing – no improvement. Please escalate this to the One UI / Wear OS team.
We have identified that the issue may occur when the sensor-related internal values are not properly reflected in the latest software (One UI 8.0 Watch) for the Galaxy Watch4 series device.
We are preparing a SW patch version for the Watch to address this issue. Please ensure that your device’s SW version is always up to date.
The update will be rolled out gradually. The schedule and version number are subject to change and may differ depending on your region or carrier.
