Warning issued for Dexcom G6 users as Android 16 update causes compatibility issues

If you use the Dexcom G6 app on your Android smartphone, the newest Android 16 operating system may disrupt how the app functions.

What you need to know

Dexcom has confirmed that the G6 mobile app currently does not work properly with Android 16. If you haven’t yet updated your phone’s software, you are advised not to install the update until Dexcom releases a compatible version of the app.

This warning does not apply to Dexcom G7 or Dexcom One Plus users, and people who haven’t updated to Android 16 are unaffected.

What to do now

Avoid installing Android 16 if you’re a G6 user.

Check your phone’s settings and turn off automatic software updates to prevent an unintentional upgrade.

If your app is still functioning, it means your phone hasn’t updated yet, keep it that way for now.

Already updated to Android 16?

If you’ve already installed the update, you might find that the Dexcom G6 app no longer works. This may also affect other devices connected to your CGM system, like the Omnipod 5 insulin pump, which depends on the app for Automated Mode functionality.

Dexcom is collaborating with Google to resolve this, and an app update is expected in the near future.

What are your options in the meantime?

Use a backup device if you have one, such as a Dexcom G6 receiver or a different phone running an earlier Android version.

Contact your diabetes team – they may be able to supply a Dexcom G7 system temporarily.

If you’re considering rolling back your phone to a previous Android version, speak with your device manufacturer, but be aware this may result in the loss of personal data, including your glucose readings.

In case of emergency

If you’re experiencing difficulties managing your insulin due to this issue, it’s crucial to contact your healthcare provider as soon as possible.

We’ll continue to share updates on this situation as soon as we have them. If you have questions or need direct support, you can reach out to Dexcom’s customer care team at 0800 011 6132.
