I am a FreeStyle Libre 2 Sensor user – how can I tell if I am impacted?

If you are a using a FreeStyle Libre 2 Sensor with a smartphone running the Android 13 operating system you may be impacted. During extended periods of signal loss, you will not receive low or high glucose alarms, however this will not impact your ability to get glucose readings by scanning your Sensor.

Please reference for additional information.

What should I do if I’m experiencing signal loss?

If you experience extended periods of signal loss, either of the following actions should allow reconnection:

  • Turn Bluetooth OFF and then ON again from your Android smartphone settings
  • Turn your smartphone OFF and then ON again
  • You may have to repeat these steps as this issue may recur
  • We also recommend that you configure your signal loss alarm to be ON with “Override Do Not Disturb” enabled. Please refer to for more information on how to configure alarms.
