How to Hide Messages You Have Read on Facebook Messenger on Android

Open Messenger. It’s the blue chat bubble icon with a white lightning bolt in the app drawer.

Tap and hold the conversation. A pop-up menu will appear.

Tap Archive. This removes the conversation from your Inbox and places it into a hidden archive. To view a hidden conversation, type your friend’s name into the search box at the top of the screen, then select the conversation. The conversation will re-appear in your inbox if that person sends you a message. To re-add it to the inbox yourself, send a reply.
