How to prevent Facebook Messenger calls from popping up on my lock screen?

[FaxMachine]

Hi, I'm new to Android Central. I've been lurking this forum for a couple of weeks and finally decided to make an account.

I'm having trouble stopping facebook messenger calls from appearing on my Note 7's screen. Here's what I've tried:
- Disabled "show on lock screen" from central settings
- Disabled "show content on lock screen" from central settings
- Heck I've even complete disabled all notification from messenger in both the central settings menu and the app menu
- Turned on "do not disturb"

None of these work

The only thing that works is turning of wifi haha which is not an ideal solution.

Is there anyway to stop facebook call from randomly invading my phone's screen even while its locked?

Thankssss

Get rid of FB lol

Not really sure the best way to stop it, facebook and Facebook Messenger are some of the most intrusive apps ever.

Aww was hoping for a magical solution

Unfortunately I need the messenger app to communicate with some of my friends. I agree, FB is annoying. Can't live with it, can't live without it.

However I didn't have this issue on my iphone. I could stop it from vibrating and showing messenger calls on my screen. Surely android can do better?
