If you’re working in a message window, messages that you receive from that contact are displayed. Otherwise, you receive a new message notification and a new message icon appears in the Status Bar. When you tap the new message notification, the Message screen opens where you can reply to the message. If the New message pop-up setting is activated, you’ll receive a pop-up notification on the current screen which you can use to directly reply.
If the Auto-retrieve setting isn’t checkmarked, tap Download (at the bottom of the screen) to view the full message.
If the message contains a media file, tap the Play button to view, watch, or listen to it. Touch and hold the media file to open a Context menu with additional options.
