Dexcom recalls G7 CGM Android App versions 2.8.0 and earlier that don't alert users when glucose sensors fail, risking missed hyper/hypoglycemia events. Affected users should update to newer app versions.
The affected devices are the Dexcom G7 Continuous Glucose Monitoring System (CGM System) using iOS, watchOS and Android App software (versions 2.8.0 or earlier) and Dexcom ONE+ CGM System using iOS and Android App software (versions 1.4.0 or earlier), henceforth referred to as the App . The affected App does not provide an expected "Sensor Failed" alert when the transmitter sends a "transmitterFailed" error message to the App when the CGM experiences a hardware or firmware failure. Instead, the App ends the CGM sensor session, stops reporting glucose values and displays the Start Sensor screen or No active sensor message without alerting the user, which can lead to missed detection of a hyperglycemic or hypoglycemic event and a delay in treatment.
Dexcom is recalling Android apps for its G7 glucose monitor that don't warn users when sensors fail. This could cause missed high or low blood sugar events without timely treatment.
The app stops reporting glucose levels and shows a 'Start Sensor' screen instead of alerting when the sensor fails. This means users might not detect dangerous high or low blood sugar events until it's too late.
People using Dexcom G7 glucose monitors with Android apps version 2.8.0 or earlier are affected. Those with diabetes who rely on continuous glucose monitoring are most at risk.
Check if your Dexcom G7 CGM Android app is version 2.8.0 or earlier. The product code SW12299 with lot code UDI: SW12299 - 00386270001870 indicates the affected model.
Update the Dexcom G7 Android app to version 2.9.0 or later to fix the sensor failure alerts.
No, the recall requires updating the app, not stopping use. Continue using the device but update the app to a newer version.
The app may stop reporting glucose levels and show a 'Start Sensor' screen instead of alerting when the sensor fails, risking missed high or low blood sugar events.
The recall states the hazard could lead to missed detection of hyperglycemic or hypoglycemic events, but does not specify a risk of serious injury in normal use.
