Lumia McLaren has been leaked many times, but in images only and while we have heard about its 3D-Touch UI, there has been no way to find out what that means in real-life use. The same source that has leaked a Lumia prototype with 5.2-inch display & Snapdragon 810 earlier has also posted images and a hands-on video of Lumia McLaren.
The leakster has tried to demo 3D interaction on Lumia McLaren but there is nothing shocking in the demo and you can do similar stuff on your Lumia devices with super-sensitive touch enabled. So, it may be a bit disappointing for some. But in case you want to see Lumia McLaren in action, watch the video below.
