Help with my Samsung LG

[AC Question]

I have an Samsung LG. It has recently stopped letting me upload photos to facebook. When I go to share the pic the drop down box doesn't have the FB icon in it anymore. Where did it go and or why is it gone?? How do I get it back?? I know this may sound easy to some but for some reason I can't figure out how to get it back.....Thank you!!
