LG may be gearing up to launch a Windows Phone smartphone after a gap of nearly four years. Twitter user @evleaks , known for his accurate tips related to unreleased smartphones, has posted a render of a large screen Windows Phone 8.1 handset, with the monicker LG Uni8. The phone featured in the image has very thin bezel and sports virtual, on-screen navigation keys similar to the recently launched Nokia Lumia 630. It runs Windows Phone 8.1 as evident from the background wallpaper and on-screen keys.
