Can we fix the problem? No. If you can tell us what it is, we might be able to tell you how to fix it, but we don't make phones, we don't write apps and we don't run whatever system you're using to do whatever it is you're doing.
If you're talking about the Facebook app, though - it's probably the Facebook app. Facebook is a good concept for some people, but the app is the opposite of good. Use your web browser to go to Facebook.
