I have a galaxy tab 2, 10.1 (model number GT-P5113, android version 4.0.4).
Up to maybe 2 weeks ago it showed all the notification available......facebook, gmail, app updates, games installed reloaded......but now it doesn't show any facebook notifications, and no "app updates available" notifications.
The notification options is green and active.
How can I fix this ?? Any and all help appriciated
