Google has released the Play Store 5.0.31 update, which includes a new layout, icon, and design. The icon has been updated to a flatter look that fits the new theme. The design update follows the Material Design layout. Lastly, the “What’s New” section on the new store shows what has been updated on the app and is at the top of the app page and highlighted in green. Google will be pushing the update to devices throughout this week, so either be patient to get the app, or download it here: http://www.apkmirror.com/apk/google-inc/google-play-store/google-play-store-5-0-31-apk/.
