The Short Version
Google fixed a Find My Phone crash on Pixel Watch 3 and 4 by May 30, 2026, but the ECG app remains broken after the same update.
Google patched the Find My Phone crash on Pixel Watch 3 and 4 by May 30, 2026, but the ECG app, which reads your heart's electrical activity to screen for irregular rhythms, stayed broken. One fix, one still-open problem. A health feature failing on a health-focused watch is a bad look, and 'we fixed the phone-finder' is cold comfort to anyone who bought the watch specifically for medical monitoring.
