Samsung has been relatively quiet in the Windows Phone ecosystem of late, but as noted by WPSuperfanboy is has recently updated a number of its own Windows Phone 8 apps (Now, Music Hub, MiniDiary and Photo Editor), suggesting the Korean manufacturer is continuing to provide some level of support for its existing Windows Phone devices.

None of the apps have a chnage log available, but the updates are likely minor bug fixes and performance improvements.  Some device manufacturers release the latest build of custom apps in line with the release of new hardware, so the updates may also tie in with the timing for the upcoming release of a Samsung Windows Phone 8 handset on US operator Sprint.

Now (updated to version 3.6.2.2) brings essential daily information in a single panorama view:

You can check today's weather forecast, the latest stock market figures, the currency exchange rate, or read up the latest headline news and top tweets. It’s very easy to access all the information by swiping from side to side. Using push technology, live contents such as current weather and news could be updated on the tiles.
