On any phone I get, I disable Play Music, Whatsapp, Hangouts, Google Photos.
Play Music sucks as a music Player IMO. The Samsung one is better. The streaming service is unavailable in my country, so I use Spotify. In short useless.
Nobody I know uses Whatsapp. We're all Viber and Facebook Messenger. Same goes for Hangouts.
I upload to OneDrive, not Google. And I don't like the app cluttering the place when I prefer the Samsung Gallery.
