Google is rolling out a new feature to its Play Store app, which should prove as quite a nice addition.
The Google Play Store app, now displays the numbered star rating for all apps and games, just below the name of the app.
The above screenshot shows you how it looks like. The new style ratings appear everywhere in the Play Store, in the My Apps page, in the search results, and even in the general Play Store sections which you browse. Prior to this change, the Play Store app displayed the rating in stars only.
The feature is a server end change, so your phone/tablet should have gotten it already.
