Login via Facebook fix for our Android App

We have a android app that is experiencing issues with the Facebook login feature. The Facebook login feature does work the majority of the time on the majority of the phones however it seems to effect only some phones. You may need to work with some debugging tools to work out what is the issue is so that you can fix this for us.

Our android application is built in JAVA and is a Native App.

When we chat i will share a video of the bug when we attempt to login via Facebook.
