Google has released a version 2.0 of its Contacts app, that has hardly changed over the years. The new update brings better design with a cleaner UI and adds some developments in terms of usability for its Pixel and Nexus users.
You will not notice any changes in the regular contacts list, which is where all your contacts are displayed. The changes are a bit deeper. One of the most obvious changes is cleaner contact page.
While the earlier version of the app used a massive image (taking up the top half of the page) with the bottom half for details, the new one takes that massive image and turns it into a small circle with the name of the contact below it.
