The above image of Lumia 1520 has been posted by Nokia on its official Facebook account. The square tiles showing Here Transit and Creative studio look odd because of their size. It is nothing seen before on a Windows Phone. It looks like equal to 4 mid-size tiles put together in size. May be we will see more tile sizes with upcoming Windows Phone 8.1 update.
May be it is nothing. What do you think?
Thanks Ronit for sending this in.
