Why won't my phone screen light up when I get notifications?

[aisaleen]

I have a Samsung Galaxy Grand Prime with 5.1.1 os. The screen lights up (turns on) when I get text messages but does not do the same for other apps like Facebook messenger and snapchat. I like the screen to light up so I can see notifications when it is on silent. Any help is appreciated.

Hi. Not sure if that is something you can set for other things besides sms.
