Hi,
I have freshly factory restored my Samsung Galaxy Note III, Android 5.0.... the first app I installed was GCM....and still getting these messages. I had to reset my phone completely, because it was overheating and had some serious problems with battery. ... and it seams, that GCM was causing them :((
I already thought about uninstalling it, syncing my Fenix3 only by wifi and accesing connect through web browser. ciq.forums.garmin.com/.../1241820.png
