Dexcom G5 Mobile App - Android FAQs

1) Transmitter Not Compatible Message

The transmitter you are trying to pair is not compatible with this app. Transmitters shipped before November 9, 2016 will not work with the G5 Mobile Android app. You may be eligible for a new transmitter immediately or in the very near future. Please contact Dexcom or your preferred distributor to order a new transmitter.

2) Why doesn’t Dexcom support my Android phone?

Dexcom completes testing on each of the phones that we support to ensure that the Dexcom G5 Mobile CGM system meets safety, quality, and usability standards. In addition, phones must meet minimum Operating System requirements. Because there are several thousand Android models available on the market, it is not possible to complete the necessary testing on every Android device. We support some of the most popular flagship phones from several manufacturers. All of these phones meet our testing and OS requirements.

3) When will Dexcom be adding support for my phone?

We continually assess possible support for new phones as they become available. Dexcom tests our apps on new phones that we plan to support after they are publicly released. It may take several weeks or more to complete testing and update the app to be fully compatible with a new smart device. Dexcom recommends checking our compatibility chart before purchasing a new smart device.

4) Can I view my Dexcom G5 Mobile CGM data on an Android Wear Watch?

Yes, you can check your CGM information on your wrist! The Dexcom CGM App for Android supports Android Wear Watches and can be used to discreetly view your glucose reading, trend arrow, and trend graph. Your Android Wear Watch will only communicate with your Android smart device, not the Dexcom G5 Mobile Transmitter. You will not receive alerts, alarms, and other notifications on the watch unless it is connected with your smart device. For example, if you have your watch on and you go out, but leave your smart device at home, you will not receive any CGM updates. Your Android Wear Watch syncs your current CGM data from your smart device. There may be a brief delay before your watch face shows current information.
