Messenger?

Okay so my partners notifications say contents hidden.

He claims he doesn’t use Facebook messenger but yesterday ok his phone there was a video icon from Facebook that came though on his phone with obviously “contents hidden”

Instead of the messenger icon, it was like the video call camera icon that you click to video call.

Does this mean that someone had tried to video call him? He said it was a friend suggestion but I’m sure that would come through as a normal Facebook notification with the “F” and if it was a Facebook message it would have came through with the normal messenger symbol.

I’m not to sure how androids work as I have an iPhone and he has a Samsung but this just isn’t making sense to me as to why they’d be the camera icon from messenger if it was a friend suggestion.

Also when his Snapchat goes off it says the contents hidden and I’ll ask who it is and he’ll just say one of his friends. But how can he know that if he can’t even see the notification?

Idk he’s cheated before and got caught.

the fact his notifications are hidden is making me think and especially the Facebook one and how he moves about the snap one.

The notification looked like the blue camera
