Dexcom recalls ONE+ iOS CGM App versions 1.5.0 and 1.6.0 due to software defect causing delayed glucose readings that may lead to missing hypoglycemic events.
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a risk that users may miss detection of a hypoglycemic or hyperglycemic event, or make treatment decisions based on outdated glucose information.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 ONE+ iOS CGM App versions 1.5.0 and 1.6.0 because a software issue can cause delayed glucose readings. This risk means users might miss low blood sugar events or make treatment decisions based on outdated information.
The app's software defect causes delayed processing of glucose readings. When the app runs in the background, it may miss critical glucose changes, leading to potential hypoglycemia or hyperglycemia events if users don't notice outdated readings.
People using Dexcom ONE+ Continuous Glucose Monitoring System with the affected app versions are at risk. Those with diabetes who rely on real-time glucose monitoring are most vulnerable.
Check if you have the Dexcom ONE+ iOS CGM App version 1.5.0 or 1.6.0. The software version is listed in the app settings or on the device's packaging.
Update to the latest app version to fix the software defect.
No, only users with the app versions 1.5.0 and 1.6.0 are affected.
The app may delay glucose readings, potentially causing users to miss hypoglycemic or hyperglycemic events.
