Why am I getting Signal Loss?

The Signal Loss Alert occurs when your display device* temporarily stops getting glucose readings from your Dexcom G7 sensor. Your last sensor reading will show on your display device for 10.5 minutes, if a new reading does not come in after that time, your display goes to —, indicating that there has not been a reading. After that, your display screen will show the Signal Loss error message.
Your display device may be too far from your sensor or there may be something, such as a wall or water, interfering with your sensor and your display device. Smartphone settings, like certain battery optimization options (see Battery Optimization settings in the recommended iPhone or Android phone settings) can also cause Signal Loss. The Dexcom G7 sensor only sends glucose readings by Bluetooth for a short period of time once every 5 minutes, so once you correct the issue, it can still take a while to see a new glucose value.
