Here i am with the exactly same Problem as you all guys have.
I have my brand new iPhone 6 spacegray 64gb since about nearly 1 month. Yesterday i randomly pressed the screen in the bottom right corner and i noticed, that the Screen made some noise. So i watched it more closely and noticed, that the screen doesn't fit exactly in the body. It protrudes a little.
And if i press the screen in the bottom right corner, the screen makes some noise, not everytime, but sometimes. But my biggest "Problem" is, that the screen protrudes a little from the aluminium body.
So i made an appointment at the genius bar...lets see if the gonna exchange it. Ist that an issue or is it normal?
I have no clicking in the left top corner.
