Today, not Google, but an actual XDA developer member who goes by the name of Proseray released the Google Play Store 4.4.21 APK, which is the same as the update users are now getting over the air that we wrote about in the post link above. To get the full explanation of what this Google Play 4.4.21 APK has inside you can read the report here.
It is still the same Hamburger build. On top of that, there are improvements and enhancements also.
If you don’t want to wait for the OTA then here is the APK for you to download instead.
You can expect to find slightly adjusted graphics inside also, with a more polished look when compared to the last application.
Apparently, according to certain Google members, we can expect to see a few more of these in the near future.
