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 the recent testing it's been doing on its UI surfaceof work Facebook, which display comments as group conversations.
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 use a brighter shade of it blue for a slightly higher overall color contrast that will make the texts more readable.
Link previews are slightly larger (they will take up the full width of your screen) and the Like, Comment, and Share buttons 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.
Facebook will release the new UI design "in the coming weeks."
