"A communications error has occurred."

Cause[]

Fire Emblem: Heroes uses Google's SafetyNet API to detect modified devices for cheating purposes. If SafetyNet flags your device as not OK, you will eventually get this error. This is a common occurrence on rooted devices.

There is also currently a known bug which causes the error code for devices that pass SafetyNet.

Solution[]

NOTE. You will lose your current account and restart game progress with this solution UNLESS you have it linked to a Nintendo ID.

On rooted phones, using your File Manager of choice, navigate to the game's files and find the following file. By default, this should be:

/data/data/com.nintendo.zaba/shared_prefs/deviceAccount.xml

Delete this file and restart the game.
