Nokia might no longer be the sole Windows Phone player to take the platform seriously, as Samsung apparently plans to exploit the operating system’s newfound Full HD support by rolling out a high-end handheld so far known as the SM-W750V.

Samsung ATIV S

Said device has last month popped up in the rumor mill for the first time, thanks to a Zauba listing, and now a Bluetooth SIG certification and User Agent Profile helps fill in a few blanks.

First off, this is indeed a phone (well, duh), one prepped for North America (now we’re getting somewhere), and rocking 4G LTE connectivity. The UA Prof also reveals the default pre-loaded browser is Internet Explorer, meaning there’s absolutely no way the SM-W750V runs Android.

But the truly big news is the display resolution is listed, at 1,920 x 1,080 pixels, otherwise known as Full HD. And since Zauba already disclosed the size – 5 inches – we can also work out the pixel density: 440 ppi.

SM-W750V

Sure, by the time the big guy lands, Quad HD (or 2K) contenders from Sony or Samsung may themselves be official and ready to roll, but some consider 1,080p+ pixel counts overkill, so in the end the SM-W750V could have what it takes to go toe to toe with each and every other 2014 flagship.

Let’s just hope Sammy doesn’t mess up the processing speed, RAM, battery size or design. Or pricing. Yup, variables still galore, so my advice is to dream small until the ATIV S follow-up breaks cover. Which rumor has it will happen next month, in Barcelona, at the Mobile World Congress (MWC).

Then again, between this, Sony’s almost certain Windows Phone dive and Nokia’s on-the-rise prestige, it’s crystal clear Microsoft’s perspectives in the mobile game are brighter than ever. Time for Android and iOS to start fearing WP? You tell us.
