Why This Matters

The recent Fitbit update has caused Pixel Watch users to lose access to key health sensors like SpO2 and skin temperature tracking, highlighting ongoing challenges in wearable device reliability and software updates. This issue underscores the importance of robust update processes and user trust in health data accuracy, which are critical for consumer confidence and the broader health tech industry. Google's response indicates efforts to resolve the problem, but the disruption reveals vulnerabilities in wearable health ecosystems.

TL;DR Some Pixel Watch owners say SpO2 and skin temperature tracking stopped working after a recent Fitbit update.

Google and Fitbit have acknowledged the permission reset issue and say work is underway to restore access.

Reports include both Pixel Watch 3 and Pixel Watch 4 users, but it’s unclear how widely the bug is affecting owners.

Google launched the Fitbit Air yesterday, giving its wearable lineup a fresh screenless tracker and a new entry point into its revamped health platform. But the company is also getting some less welcome feedback from another corner of its wearable ecosystem, as some Pixel Watch owners say a recent update has broken SpO2 and skin temperature tracking on their current devices.

The issue was raised in a Reddit thread on r/PixelWatch, where a Pixel Watch 3 owner said a recent Fitbit update had reset permissions for skin temperature and SpO2 tracking. The user said they couldn’t simply turn the permissions back on, as the permissions page showed that no app was requesting them. A few other commenters reported similar problems in the thread.

In that post, a Pixel Watch 4 owner said the same sensors had stopped appearing in the Pixel Watch and Fitbit apps for more than a week. FitbitHelpCommunity later replied with almost the same message, again pointing to the same firmware update and saying work is underway to restore access.
