Dexcom recalls G7 CGM watchOS app versions 2.9.0-2.11.2 for potential glucose data delays that could cause missed hypoglycemic events. Affected users should check their app version and contact Dexcom.
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a risk that users may miss detection of a hypoglycemic or hyperglycemic event, or make treatment decisions based on outdated glucose information.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 its G7 CGM watchOS app versions 2.9.0 through 2.11.2 because software issues may delay glucose readings, risking missed hypoglycemic or hyperglycemic events. This could lead to dangerous blood sugar levels if users rely on outdated information.
The app's software defect causes delayed processing of glucose readings when running in the background. This can make the Glucose Compass flicker through past readings and potentially miss critical low or high blood sugar events.
