http://androidforums.com – Hi guys, I'm still new to android how that i can learn more from this forum. My problem: It seems like I will only receive notification update from facebook/facebook messenger when my phone is connected to the wifi. Any idea how to fix it? Is there way to make my screen light up + vibrate whenever i receive any notification? Here is the screenshot of my facebook/fb messenger notification settings Edit: Sorry my phone is galaxy note 2... Didn't notice there is note 2 section. =x (General)
