Do you guys have this issue? the official facebook app forgets the notification sound setting and defaults back to SILENT all by itself. It does not even require a reboot, you set it, and ramdonly, sometimes even 5 minutes after is back to the default of SILENT.
It does not matter what rom or kernel, for my phone it has done this on every rom and kernel I have tried. I do get the notifications in the notification bar at the top, that works no problem. Is just the sound setting that goes bye bye.,
I have the same problem. Facebook notification settings revert to the 'default' settings on some random basis. I tried lots of stuff including clearing the app cache. The vibration setting ends up draining the phone's battery sooner than any sound. It's extremely annoying.
