This is something which Samsung wont surely agree to. Other specs are, a dual-core processor and a very good camera, perhaps a 3D one.

Next up, is the iPhone 5 this concept is also created by the same guy Chris young while looking at the pic here I'm more than sure that you wont get impressed but still, it makes us think, get it? This iPhone 5 involves a 3D Crystal touchscreen, a 16MP camera and 2.5Ghz processor. This iPhone 5 provides an incredible 52 hours and 24 hours of audio and video playback respectively.
