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a risk that users may miss detection of a hypoglycemic or hyperglycemic event, or make treatment decisions based on outdated glucose information.
