So now you have me wondering. And let me 1st say that as a previous owner of a Galaxy Note, I would love a 5-5.3 inch screen and do think this will be slightly too big for my taste. But your "question" has me wondering about something. If it would be possible for smaller 1080p screens to have the screen wide tiles, why would it not be possible on the larger screens? Isn't this directly related to the resolution and not the screen size? That was my understanding up to this point anyway.
Part of me thinks that the tiles on this "leak" were arranged that way just to show the extra row and don't necessarily mean it won't be possible, but I am still concerned. We will know soon enough I guess, or maybe not, depending on when we actually get info on the capabilities and features of GDR3 which may not be the same time as the unveiling of this device. I just have a hard time imagining them, after promoting the idea of wide tiles that display info, removing the ability to have them display the whole width of the screen. Having said that, with my luck, much like with TV shows, the things I like usually don't last.
