Symptoms
- ECG app is missing or grayed out
- App says ECG isn't set up for your country or region
- Reading fails repeatedly with 'inconclusive'
- ECG worked before but stopped appearing
Likely causes
- CommonECG not yet approved or available in your countryRegulatory approval for ECG features varies by country and rolls out gradually.
- CommonECG app not set up during initial watch configurationMost watches require a one-time setup step in the companion app before first use.
- PossiblePoor contact between finger and the sensor during a readingECG requires steady, correct finger placement for the full reading duration.
- PossibleSoftware update pending that includes health feature accessSome regions get ECG access through a specific software update.
What to do
- Check the companion app's health section to see if ECG setup is available for your account's region.
- Complete the ECG setup steps in the companion app if you haven't yet, which usually includes entering birth year and confirming eligibility.
- Update both the phone's app and the watch's firmware to the latest versions.
- When taking a reading, rest your arm on a table and hold the sensor location steadily for the full 30 seconds without talking.
- If readings keep coming back inconclusive, try again with clean, dry skin and a properly fitted band.
When to call a pro
If your region has ECG approved and setup complete but readings consistently fail, contact the manufacturer's support; for any actual heart symptoms, see a doctor rather than relying on the watch.
