There are 2 facebook apps on my phone: facebook app installer and facebook app manager, you can disable manager but keep the installer for oculus to work. btw you won't see the installer until you enable system apps.. The facebook app does more than help you stay connected with your friends and interests. it's also your personal organizer for storing, saving and sharing photos. it's easy to share photos straight from your android camera, and you have full control over your photos and privacy settings..
