Reports on Chinese tech sites have shown images of what could be the the new Nubia UI Android system which the Nubia Z7 will be running. From the screen shots we can see the UI has been totally reworked when compared to the current ROM found on Nubia phones with a minialmistic design.
The Notification Center is where a lot of changes are going to take place and will offer limited control over the media center, messages, toggles and recent apps.
As for the Nubia Z7 itself well it could be launching at around the same time as the Oppo Find 7 and could well have similar hardware including a 2K display, Snapdragon 800 CPU and up to 3GB RAM.[ CNgiz.com ]
