Samsung's next big flagship phone hasn't even been announced yet - but we're already starting to see some pretty interesting leaks ahead of the expected late February-April launch window.
The latest comes via the serial Twitter leak whiz-kid EVLeaks, who recently published this picture of a wildly different Samsung 'TouchWiz' home screen.
The picture is a total departure from the standard Android, towards something more reminiscent of Google Now or Windows 8.

The home screen is essentially a series of 'cards' featuring things like your home thermostat, your exercise details, favourite music and meals, notices about packages and upcoming flights.
The idea is clearly to place the information you most want and need right up front on the device, with the phone intelligently displaying what you need, when you need it.
We'll have to wait and see whether this leak is anything like the device eventually released, and whether it's a default option you can turn off or really a total re-imagining of the Galaxy S phone brand itself.
Currently there's no word on when the S5 may or may not be announced - all will likely be revealed shortly after MWC in Barcelona in March or April.
Rumours suggest it could come as soon as MWC itself - but again, we'll have to wait and see.
