Google just posted a brand new Google Camera app to Google Play this morning, just like the rumor from a couple of weeks ago suggested.
At this time, we are unable to install it, but we are seeing a brand new UI from the screenshots, along with lens Blur effects, high resolution panoramas, and a 100% viewfinder listed in the description.
The app listing does say that the app only works with phones and tablets running Android 4.4+.
