About a decade ago, there were rumors about a VAIO-branded smartphone from Sony that was to hit the market with a physical design that was quite unique back then. The smartphone, however, did not see the light of day and was tucked away somewhere in one of Sony’s facilities. Now, following the launch of Sony’s latest Xperia 5 II smartphones, we have some high-res pictures of the prototype of the Sony VAIO smartphone from 2010.

Now, coming to the “Sony Ericsson VAIO” prototype, the device rocks a 5.5-inch display with an ample amount of bezels around it. It also featured three physical buttons at the bottom, a now-gone headphone jack, and a mini USB port for charging, much like the other smartphones at that time. Image: XDA Developers

However, the differentiating factor of this smartphone was its exclusive two-step sliding mechanism.
