This error will show if your Android device's NFC is turned on as it is required to be off before recording. NFC, which stands for Near Field Contact, is a feature that phones have where your phone can communicate with devices by being physically near them. It is used for things like Android Pay, pairing devices, bus passes, etc... These devices are constantly looking for a near by device it can communicate with. Unfortunately this constant searching is an electrical signal that can actually end up in your EKG as a blip, or change in what your EKG looks like. Therefore Kardia requires NFC to be off to avoid any interference with your EKG.
If you wish to turn off NFC, you can do the following:
- Tap the "Go to Settings" button on the error screen
- Tap "Connection Preferences"
- Toggle OFF NFC by tapping the toggle so that it moves to the left
- Return to Kardia
You're all set, and the screen should transition to the normal recording screen.
