Google's March 2026 firmware update for Pixel Watch is causing major issues with Fitbit tracking, with users reporting wildly inflated step counts and calorie data. What began as missing health metrics like SpO2 and skin temperature readings has escalated into fake activity tracking, with some users seeing their daily steps double or triple while sitting at their desks.

Reports across Reddit suggest the bug affects not just those who updated, but also some users with older firmware versions. This hints at possible server-side issues rather than a purely update-related problem. The algorithm appears to be multiplying step counts and calories burned, making the watch's health stats completely unreliable for tracking actual activity.

For casual users, inflated numbers might seem harmless, but for those relying on accurate fitness tracking, this is a serious problem. Google hasn't acknowledged the issue publicly through support forums or official channels, despite mounting complaints. Until a fix arrives, Pixel Watch owners should be skeptical of their step counts and calorie data, as the numbers appearing on their wrists may have little connection to actual physical activity.
