Google is rolling out an update to its Play Store soon that lets users join Android betas programs right from the app’s listing info.
Instead of going through the developer’s sites and Google+ communities, the new feature will enable users to see which apps are in beta versions and which are public right from the Google Play store and join. There’s an option to leave feedback to developers in private as well.

The new update will officially rollout in phases. There’s also a direct link from APK Mirror if you want to test it right now.
