Although there are a lot of themes to choose from, none of the themes currently available mimic the appearance of the stock Android user interface. That is about to change soon, as Sammobile has just posted a few photos of an upcoming Samsung Galaxy S6 theme that mimics the user interface available on Nexus smartphones, which is the stock Android interface.
The theme, which has yet to show up in the official Theme Store, was designed by popular icon designer Samer Zayer, adopts near-stock icons, and also comes with a layout that's highly similar to what Nexus 4, Nexus 5, and Nexus 6 owners are currently experiencing on their vanilla Android implementations. It should be mentioned that the UI is not spot-on identical to stock Android (for instance, the quick toggles come with a different layout despite the fact that they adopt the same icons as on stock Android), although the general feel is certainly there.
According to Sammobile, the theme has been approved by Samsung. If you've been craving for a taste of vanilla Android on your Samsung Galaxy S6 or S6 edge, then this new theme should be exactly what the doctor ordered. We'll update this post when the theme becomes available for download. In the meantime, check out the screenshots below!
Update: The theme has been published in the Samsung Theme Store.
