Unable to login to any app with Facebook; page pops up & immediately disappears

[TheSpaceOctopus]

Every time I try to login to anything using Facebook, the login page only appears for a second & then goes away before I can do anything. It happens in every app I try it with. Unfortunately I absolutely need to be able to at least log in to the "Metal" app. I believe the Facebook login page for Android apps is using a special browser to display the page, but not sure if it's just a version of the stock browser or if it's an entirely different thing. Any information would be appreciated, as Google search was absolutely no help to me. It's a question with too many keywords that are too common & return only things completely irrelevant to the question.

Thanks in advance for help. It's a Note 3 & this started over a week ago I think, and I don't remember changing anything that might cause this. I froze several Samsung apps, but that was a year ago & I've never experienced this problem before now. What should/can I do?

Welcome to Android Central! Try going to the App Manager, tap Menu, then Reset All App Preferences. Now try again, and see if it gives you a choice for how to log in with Facebook. (Bear in mind that resetting all app preferences will also re-enable any disabled apps.)
