Dexcom recalls ONE+ Android CGM app versions 1.4.0 and earlier due to failing to alert users when glucose sensors malfunction, risking missed diabetes emergencies.
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 its ONE+ Continuous Glucose Monitoring System app versions 1.4.0 and earlier. These versions don't alert users when the glucose sensor fails, which could lead to missing dangerous high or low blood sugar events.
The app fails to show a 'Sensor Failed' alert when the transmitter detects hardware or firmware issues. Instead, it stops reporting glucose levels and shows a 'Start Sensor' screen, which can delay treatment for dangerous blood sugar spikes or drops.
People using Dexcom ONE+ glucose monitors with app versions 1.4.0 or earlier are affected. Those with diabetes who rely on continuous glucose monitoring are most at risk.
Check if your Dexcom ONE+ system uses the Android app version 1.4.0 or earlier. The model number SW14245 with lot code UDI: SW14245 - 00386270004314 indicates the affected version.
Look for the app version number in your Dexcom ONE+ settings or app store listing.
