Starting about ten days ago, reports that Samsung was pushing out Windows Phone 8.1 Update for ATIV S users began circulating the 'nets. We have our own ATIV S here in the house, which is an unbranded UK release, and were not able to get any such update. Instead, we are stuck on Windows Phone 8.0 GDR3 (Build 10517; Firmware 24220.127.116.11).
As it turns out, a very select few ATIV S users are getting Windows Phone 8.1 Update (Build 14157; Firmware 2418.104.22.168), which is splendid news. The bad news is it is isolated to specific regions like Austria and maybe Hong Kong.
Samsung ATIV S devices released through carriers and most other areas are not seeing the update yet, although obviously this can change. Let me try and explain and give you the full story.
