Dexcom G7 Continuous Glucose Monitoring iOS app (versions 2.9.0–2.11.2) and its paired watchOS app, and the Dexcom ONE+ iOS app (versions 1.5.0 and 1.6.0) are affected; identify by the app name and the listed software versions. A software defect can block the higher‑priority thread that processes estimated glucose values and trend arrows, causing queued EGV notifications to replay, Glucose Compass flicker, perceived signal loss, and delayed alerts. The delay can cause missed detection of hypoglycemia or hyperglycemia or decisions based on outdated glucose information.

The hazard
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a risk that users may miss detection of a hypoglycemic or hyperglycemic event, or make treatment decisions based on outdated glucose information.
What to do
Don't stop taking a prescribed medicine without talking to your doctor or pharmacist first. For other products, stop using them and ask the pharmacist, seller or maker what to do.
