I was texting with my friend, but I didn't lock my keyboard. I marked her as spam. Do you know how I can get back notifications from her messages?
I'm not exactly sure what you mean by 'marked as spam' since I can't see this option in either the Facebook app or the Facebook Messenger app. I'm assuming you mean you turned off notifications for her messages since you mention you want to get them back. I'll explain how to turn them back on.
