Delete G5 App. The Dexcom Rep said that many patients still have their old G5 app, make sure to delete this once you are using your G6 app, it can help you get a better connection.
Turn off and back on your Bluetooth. (simple but can be all your G6 app needs)
Reset NETWORK settings.
Settings > General > Reset (2nd to the last button) > Reset Network Settings
After your phone turns back on from the reset, it will ask you to rejoin your current interment network, next tap on your G6 app. It should then immediately try to pair with the transmitter that is currently connected with the sensor you are wearing. If it is unable to pair, know that this issue is more than bad signal, but it is a bad sensor. Call Dexcom Tech Support to get a new sensor (individual sensors are valued at $164).
