To coincide with Microsoft’s launch of Windows Phone 7, LG unveiled two devices using the platform, the Optimus 7 and the Optimus 7Q (also known as the Quantum on AT&T's network). Both devices featured 16GB of onboard storage and five-megapixel cameras with 720p video capture.
The Optimus 7 had a 3.8-inch screen and a slide-sliding qwerty keyboard. At the time of launch LG stated that the device would be offered in over 35 countries through 100 partners and operators.
LG underlined its commitment to Microsoft’s platform, by funding a group of dedicated engineers within the Microsoft Windows Phone 7 software team when it was developing the Optimus 7. It is likely this allowed LG to offer more differentiation on its new devices than some of its rivals — notably with the Optimus 7 being the first landscape qwerty device to ship on the platform.
Other areas where LG took an early competitive lead was by included support for Microsoft's Play To feature, which used Digital Living Network Alliance (DLNA) technology. This made it possible to stream music and video directly from the phone onto networked PCs, TVs and other DLNA-enabled devices around the home. LG had also implemented a compass application programming interface (API) to support ScanSearch, an augmented reality application developed with Olaworks. Other exclusive developments included a voice-to-text application and enhanced camera features including panorama and "beauty" modes.
Since 2009, LG had worked closely with Microsoft, having committed to a multi-year agreement to deliver 50 Windows Mobile devices by the end of 2012. In the end, this was a target it never came close to reaching.
