To reread a message

When you open a conversation, messages that you’ve already read are minimized into a tab that indicates the number of hidden messages.

1. From your Gmail Inbox, tap the conversation you want to view.

2. Tap the contact name to open that message.

   While reading a message you can tap the Unread icon (in the Gmail Inbox header at the top of the screen) to return a read message to the unread state. For example, to remind yourself to read it again later.
