Reports of sensor failures after the Wear OS 6-based update suggest Samsung may have paused the rollout—users advised to hold off on updating.
New Update, New Problems for Galaxy Watch 4 Classic
Samsung’s long-awaited One UI 8 Watch update—based on Wear OS 6—has landed on the Galaxy Watch 4 Classic, promising a sleeker UI and smarter health features. But for at least some users, the update appears to be doing more harm than good.
- A user on the Samsung Community forum (India) reported that key sensors stopped working after the update
- Wrist detection, Bioelectrical Impedance Analysis (BIA), and ECG sensors all failed diagnostics post-update
- Factory reset and cache clearing did not resolve the issue
“After the update, nothing worked—until I flipped the watch onto my palm,” the user said, suggesting potential sensor misalignment or calibration issues.
Diagnostics Show Sensor Failure After Wear OS 6 Update
The user shared a screenshot from Samsung’s built-in diagnostics tool, confirming sensor failure across multiple key health features.
- Even basic functions like wrist detection seem to be compromised
- The workaround—wearing the watch with the display against the palm—points to possible software calibration bugs, not outright hardware failure
Still, it’s a worrying development for users counting on these features for health tracking, ECG readings, or body composition monitoring.
Is Samsung Pulling the Update?
Several commenters noted that they haven’t received the One UI 8 Watch update yet, despite being eligible, raising speculation that Samsung may have paused the rollout to investigate.
- Samsung has made no official statement yet about the bug or a temporary halt
- However, the timing and user reports strongly suggest an internal pause or delay
- With Galaxy Watch 4 and Watch 4 Classic users sharing the same hardware baseline, others in the series could also be at risk
Should You Update? Maybe Not Just Yet
If you own a Galaxy Watch 4 Classic, you may want to delay the One UI 8 Watch update until Samsung issues an official fix or clarification.
- For now, sensor reliability may be compromised after updating
- If health tracking is important to you, it’s worth waiting to see if Samsung confirms and patches the issue
As always, backup your data and check community feedback before applying major OS updates—especially on aging hardware.
TL;DR:
A Galaxy Watch 4 Classic user reports that sensors like ECG and wrist detection stopped working after updating to One UI 8 Watch (Wear OS 6). While not widespread yet, others haven’t received the update, suggesting Samsung may have paused rollout. Users are advised to delay updating for now.
