A redesign of the Google Play app appeared briefly on a Google+ account before the post was pulled.
YouTube’s Eileen Rivera posted a screenshot of a redesigned Google Play app to her Google+ page, but the link now comes back as broke, and perusing her main feed also yields nothing. It appears that perhaps this was not yet meant for public consumption.
As AndroidCentral points out, if you look in the top left hand corner of the screenshot you will see a dog bowl. This is likely a reference to this being a “dogfooding” – or internal company usage – version of the app. That could also mean that there will be some more tweaks before it is released.
Seeing as the image has been pulled, there is no real indication of when, if ever, this refresh could make its way to the public. With Google I/O right around the corner, though, it seems like that would be a likely timeframe for this to make its debut.
