The applications for cell phones of Facebook they will acquire new look. The most obvious change seems to take place in the remarks, which will look much like an ongoing debate.
The new look is in line with its recent testing of the Surface UI work Facebook, which display comments like group chats.
The idea is obviously to make comments a little more readable and to see more easily who is responding directly to another person.
Facebook may also be trying to make conversations with strangers a little friendlier. The similarity of the context of the text with those from a application messaging can make you feel like you're having a personal conversation with the participants, rather than replying to a random online thread.
Less obvious will be the changes in News Feed.
Facebook will uses a brighter shade of blue for a somewhat increased overall color contrast that will make texts more readable.
The link previews are slightly larger (they will take up the entire width of your screen) and the Like buttons, How, and Share will be somewhat larger.
As the official announcement of the upcoming changes to the larger social network looks and says, there will also be many other small tweaks such as a more visible back button and the ability to see where a link will go before you click on it.
