The company hasn't yet integrated its own UI vision in Windows Phone
One of the privileges that Nokia has been granted with when adopting Microsoft’s Windows Phone platform as its main operating system for smartphones was the possibility to tweak the UI as it considered it fit.The company’s first Windows Phone devices come with the same OS appearance as all the other devices do, but things might have been different.
Or they could change moving forth, as the concept UI images embedded below show.
Apparently, Nokia’s vision of Windows Phone’s UI is showcased in those images, at least this is what a recent article on Pocketnow states. The shots come from one of Nokia R&D's senior graphic designers who now works for Accenture.
Nokia did confirm before that it had the freedom to modify the UI as it pleased, but it still remains to be seen whether it will apply any of the ideas that can be seen below.
