Why can't I get Facebook on my phone?

[AC Question]

Cannot get Facebook on my phone

My facebook disappeared and I get a black screen when I click on the facebook icon. I then have to turn my phone off because the black screen locks usage of my phone

Welcome to Android Central! Which phone? Go to Settings>Apps, select Facebook, and Clear Cache/Clear Data, then Force Stop. Then open it again and log back into your account. Does it work now?
