Shared Media. Tap the header in any chat to open its Shared Media page – containing all the photos, videos, music and more that have been sent there. Drag the date bar to swiftly scroll back years in the past, and tap the bar to open a calendar view with media previews for each day. Tap ➕ or ➕ to show only photos, only videos, or both and pinch to zoom in or out and change the size of the previews – then press and hold on any thumbnail to jump to its place in the chat.
