Facebook (fb) app does not do or save some setting and I get a popup message at bottom of screen which seems to be coming from the phone itself. Cleared data and cash, no good, uninstall app which leaves the factory version, cleaned phone data and cash switched off phone. Try to download app again via play store but say it already installed, so start factory one and it downloads updates but still the issue persists. Its been happening for months so I'm sure if it was a fb issue they would have eventually sorted it with new updates, any ideas
