While Windows Phone 8.1 was authoritatively advertised by Microsoft this week, just Nokia displayed new WP 8.1 fittings: the Lumia 930, Lumia 630 and Lumia 635.Be that as it may different producers ought to join the gathering soon. As stated by Sam Mobile, the Samsung ATIV Core offers a 4.5-inch show with 720 x 1280 pixels, a 8mp or 13mp back Polaroid, 1gb of RAM, and a 2,100 mah battery. This should be the exact first Windows Phone 8.1 gadget from Samsung. Lamentably, there are no pictures to go hand in hand with this report, so we don't realize what the asserted ATIV Core looks like (what we're seeing above is the more established Samsung ATIV S). Prior today, Verizon uncovered the Samsung ATIV SE - an alternate new Windows Phone handset made by the South Korean organization. On the other hand, this will be discharged with WP 8 ready for (it will surely be upgraded to WP 8.1 after that). There is no statement on precisely when Samsung expects to launch the ATIV Core, and not, one or the other on what markets will get it. At the same time we'll tell you when we discover.
