How to fix if Unfortunately Facebook has stopped on your Android

1) Go in settings
2) Then in Applications manager
3) Search for Facebook
4) Delete cache and data
5) Back to your homescreen and restart

If by any chance, this method didn t work, U have to use the last version of Facebook or an old version, it depends of your android version and your phone. So try the tutorial with apkeditor to edit your build number. And then if it s still not working…so I can t do nothing for u ! It could mean the version of the app is not compatible with your phone ! Upgrade your android version or back to the blue
