Dexcom G7 iOS App (Dexcom) – Glucose Value Bug (2025)

Check Your Product

According to the U.S. Food and Drug Administration (FDA)

Reason for Recall

As stated by FDA

A bug in the 2.7.0 version of the G7 iOS App can cause the app to enter a state where it stops updating the estimated glucose value (EGV) and continues to show this stale EGV. If the user is unaware that the EGVs are not being updated and that glucose alerts will not trigger, there is potential for the missed detection of a hyperglycemic or hypoglycemic event or a treatment decision made based off incorrect data. There is no impact to transmitter communication with concurrently connected displays. A concurrently connected receiver, Apple Watch, and/or insulin pump will continue to receive EGVs directly from the transmitter when the app is in the problematic state. There is no impact to Automated Insulin Dosing (AID) therapy as the AID system continues to receive EGVs directly from the transmitter.
