Hi everyone, I have a strange problem with Facebook notifications to my Samsung Galaxy s2 (ICS updated). Generally when I receive a message the notification sits silently in the top corner since I have set the sound to silent, but when I get a private message from a couple of people in particular I get an incredibly loud ringing notification which is really embarrassing and goes on until I open the phone. I have been through all the settings that I can find and I really can't figure out why this is happening and various searches on the internet have come up with nothing. Does anyone have any idea why this is happening, it's driving me nuts! Any suggestions appreciated.
