The redesign, which appears to be based on lessons learned by Instagram, aims to make users' photos appear larger in their news feeds than they were before.
Facebook today unveiled a new mobile redesign aimed at making news feed photos up to three times larger on iOS, Android, and the social network's own mobile site.
"Starting today, we're rolling out an improved design for posts in news feed on your mobile phone," Facebook said in a post. "Now photos are up to 3x larger, and all posts will fill your mobile screen from edge to edge."
The move appears to be based on cues from Instagram, the mobile photo-sharing service Facebook bought last month for $1 billion. In screenshots of the changes Facebook published, photos that used to be pretty small in a user's news feed now are much larger and easier to see, and stretch from one side of the screen to the other.
In a post on the new design, TechCrunch suggested readers would like the changes because photos will now be much larger. But in the comments thread on Facebook's own post, users don't seem too happy. There, comment after comment reflected users' weariness with never-ending feature changes by Facebook.
