Facebook Messenger – How to Search for Sent Files

Here's how I get around it using Android Chrome:

1. Go to m.facebook.com
2. Click on the Chrome menu dropdown on the far right of the address bar
3. Toggle the "Request desktop site" option
4. Now click on the FB messages tab

You may not have the desktop site option depending on your phone. I'm not aware of any other way to do this.

Go to the app-version of messenger. Click the chat head in the left upper corner with your own image. A menu appears. Choose message requests. You come to a folder separated in two categories. Choose Spam. These are the messages marked as spam either by you or Facebook. To get it back to your inbox, the only solution I've found so far is to reply to it, but I'm trying to find other options.
