I'm still waiting. Waiting for my Samsung ATIV-S to update to WP8.1, but according to the "phone update" screen on my WP, "Your phone is up to date".

Calling Samsung was a waste of time and so was speaking to the Microsoft call center in some far away country.

Samsung tells me one thing (waiting for Microsoft) and Microsoft tells me it is up to Samsung to release an update.

I am amazed companies continue to exist with that level of service.

Lesson learned: last time I am buying a Samsung device and the same goes for anything Microsoft.
