I gave up Samsung Galaxy entirely over this .. even ended up switching to iPhone because I couldn't find another Android I liked as much.

Every Galaxy I ever owned came with uninstallable facebook apps, despite paying over 1k for the phone.

On the last one I had, I went in and did the ritual deleting facebook, and going in the settings to disable their other background apps.

I checked the phone 8 months later, and found that they had installed even more facebook apps that were now running without my consent.

That was the end of those phones for me, and I'm amazed that I put up with it for so long.
