I think most Apps on the Google play Store are trying to adhere strictly to the Google’s Material design Requirement including Facebook which launched a new version of the Facebook messenger that will be rolling out later today.
The Facebook’s team have actually been running a design Test by implementing various material design elements which were enabled for some users though not all as they tagged it the A/B testing.But The good news is, the Latest and official design will be on the play store anytime soon for download.
Though the roll might take days to complete which is normal as regards to the time zone of your country,but then the image above will give you a glimpse of what you should be expecting.
Facebook says the redesign has been a painstakingly hard process, especially since the app is such an essential part of the lives of hundreds of millions of people across the world.
