In its latest step to upgrade its mobile presence, Facebook is shifting from thumbnails to full-sized photos and posts in mobile browsers and Android and iOS phones. Through the changes rolling out
now, images in the news feed will appear up to 3 times bigger and posts will fill the phone screen from edge to edge. The update won’t require users to download Android or iPhone apps. The move
follows up on Facebook’s $1 billion acquisition of photo-sharing app Instagram last month. See some examples of the new look here.
