The word “Play” is now more entitled in these newly leaked icons of the Google Play Store, Music, Books and all those handy apps loaded on the stock Android devices. The new icons looks more appealing and it seems like the Google Apps folder will look better with these updated icons.
The biggest change is with the Google Play Store icon which shows the Play button jump out of that old styled Windows store theme briefcase icon. It is more brighter and looks great, cancelling the fact that it will contain more flat design as expected with the official release of the Android N.
Here is the image of the older Google Music, Books and all other icons changes with the time.
