Tried but it doesn't works.. I am only getting frequent notifications from WhatsApp & gmail and none other..

so far so good.
problems found so far:
1) Notifications - erratic, not always working
2) Facebook Messenger app - invisible Chat Heads

thanks ultrametric, i tried that tut.
i found something that solved the FB Chat Heads issue.

Security App>Permissions>notification management>enable the Alert toggle for Facebook and Messenger.
