TL;DR

Instead of improving performance, the One UI 8 Watch update is apparently breaking core Galaxy Watch 4 Classic features for some users.
Wrist detection stops working, which disables health features like ECG and body composition.
Reports suggest Samsung has paused the rollout, and a fix may be coming.

If you have a Galaxy Watch 4 Classic, you might want to wait before updating to One UI 8 Watch (https://www.androidauthority.com/samsung-one-ui-8-watch-update-ditch-pixel-watch-3572376/). What was supposed to be a fresh lease on life for Samsung’s 2021 fan-favorite smartwatch (https://www.androidauthority.com/best-smartwatch-3486670/) is causing problems for some users.

The One UI 8 Watch update, built on Wear OS 6, began rolling out to Galaxy Watch 4 models in early December (https://www.androidauthority.com/samsung-galaxy-watch-4-one-ui-8-watch-3625204/). However, instead of making the watch better, users say the update is causing the sensors to stop working.
