Freshly leaked images have surfaced showing a rare 2013-2014 prototype of the unreleased Microsoft Surface Phone, offering a detailed look at what might have been for the tech giant’s abandoned mobile hardware division. According to Windows Central, the prototype—reportedly carrying the internal codename “Raven”—runs an early build of Windows Phone 8.1 and features a flat-edged metallic body with a physical Windows logo on the rear.
Before Microsoft acquired Nokia’s phone business in 2014, industry observers watched the smartphone market as a competitive three-way race between Apple, Google’s Android ecosystem, and Microsoft’s Windows Phone platform. While Microsoft ultimately exited the market and later shifted toward Android-powered hardware like the Surface Duo, newly emerged prototype photos reveal a design philosophy that predated the wider mobile industry’s transition into metal unibody construction.
The newly surfaced hardware captures a pivotal era in mobile engineering. As detailed by XDA Developers, the device incorporates physical navigation keys below its display, a single rear camera, separate physical volume buttons, a dedicated camera shutter button on the right edge, and a top-mounted power button. Additional physical specifications include a micro-USB charging port, a 3.5-millimeter headphone jack, and a side-mounted SIM card slot.
According to Windows Report, the prototype utilizes an unknown Qualcomm processor paired with a 720p display, matching the typical hardware constraints of high-midrange devices from late 2013. The chassis features a silver metal finish reminiscent of the Surface 2 tablet released during the same production window, suggesting a deliberate cross-device design language that Microsoft hoped to establish across its hardware portfolio.
Inside the Canceled Prototype: Design and Hardware Specs
The internal configuration of the “Raven” prototype demonstrates how Microsoft intended to adapt its tablet design language for a pocket-sized form factor. The device relies on an early pre-release build of Windows Phone 8.1, which debuted publicly in the spring of 2014. Industry reports indicate that Microsoft developed multiple experimental smartphone configurations during this period, with internal teams testing various chassis designs before the company pursued its acquisition of Nokia.
Hardware features on the prototype highlight a distinct era of mobile technology before manufacturers standardized ports and removed physical buttons. However, market analysts note that Microsoft never officially confirmed whether this exact prototype was intended for commercial release under the Surface brand.
The Evolution of Microsoft Mobile and the Legacy of Surface Duo
Following the winding down of Windows Phone support in 2017, Microsoft eventually returned to mobile hardware development with a dual-screen Android device. As reported by XDA Developers, the closest consumers ever came to a Surface-branded smartphone was the Microsoft Surface Duo, which began development in 2016 and launched in 2020. That dual-screen device faced stiff competition from foldable handsets like Samsung’s Galaxy Fold series.
While the Windows Phone platform ultimately failed to capture sufficient market share to challenge iOS and Android, newly uncovered prototypes provide historians and technology enthusiasts with a clearer picture of Microsoft’s internal roadmap during 2013 and 2014. As mobile archivists continue to uncover hardware prototypes from this era, public interest remains high regarding how alternative design choices might have altered the trajectory of the modern smartphone market.
