I have this same issue with device not updating. I don't want app to have full permission to all my information. Why does the app need permission to access my contacts, photos, videos, and physical activities? There's no need to have these permissions unless you want to download a picture for your fobo home screen. That is just a temporary permission not full access all the time.
