Hi Damian, thank you for your question.

Since the introduction of Android 5, several device manufacturers have added battery saving options that can interfere with our Co-Driver feature and prevent it from monitoring your driving activity. If your Co-Driver stopped working some time after activating the feature, we advise checking for a battery saving mode on your device, then reactivate the feature. Please scroll to your device manufacturer to see the specific steps:
