What are microG services?

The microG services replace Google Play services on your iodé smartphone. They allow you, among other services, to choose Google’s alternative geolocation modules. 2 modules are coupled by default: ‘Déjà vu’ & ‘Mozilla Location Service’.
‘Google Cloud Messaging’ (GCM) is a push notifications provider; it allows you to receive notifications on your iodé smartphone and a lot of android apps rely on it. We have activated the GCM provider by default, but you can deactivate it from the microG settings panel.
