A recent leak has revealed images of a Microsoft smartphone prototype believed to date back to 2013 or 2014, speculated to be a Surface-branded Windows Phone that never reached the market. The images show a sleek phone with a silver metal frame, navigation keys beneath a 720p display, and a Microsoft logo on the back. The device operates on an early internal build of Windows Phone 8.1 from September 2013. Key specifications hinted at include an unidentified Qualcomm processor, a micro-USB port, a headphone jack, a SIM slot, volume controls, and a dedicated camera button. However, details such as the chipset model, RAM, storage capacity, battery size, or camera specifications are not disclosed. The design resembles Microsoft's early Surface devices, but there is no definitive evidence it was intended for commercial release. This leak follows Microsoft's acquisition of Nokia's Devices and Services business, which was announced in September 2013 and finalized in April 2014, potentially explaining the decision to shelve this smartphone design.
