Dexcom recalls G7 CGM iOS App versions 2.9.0-2.11.2 for potential glucose alert delays. Users may miss hypoglycemic events due to software issues causing EGV flickering.
A software defect in which a low-priority file I/O check blocks the higher-priority thread responsible for processing estimated glucose values (EGVs) and trend arrows. When the app is running in the background, EGV notifications may queue up and then "replay" sequentially when the user brings the app to the foreground, causing the Glucose Compass to flicker through previous EGVs. In more severe instances, the app may perceive signal loss and deploy signal loss mitigations. This delay in EGV and alert processing creates a risk that users may miss detection of a hypoglycemic or hyperglycemic event, or make treatment decisions based on outdated glucose information.
Dexcom is recalling specific versions of its G7 CGM iOS app because a software defect can cause glucose alerts to flicker or delay, potentially leading users to miss critical hypoglycemic or hyperglycemic events.
The app's software defect causes low-priority file checks to block higher-priority threads that process glucose data. This can make glucose alerts flicker or delay, potentially causing users to miss dangerous low or high blood sugar events.
People using Dexcom G7 Continuous Glucose Monitoring System with the affected iOS app versions are at risk of missing critical glucose alerts. Those with diabetes who rely on real-time glucose monitoring are most affected.
