Is it normal in all Cliqs for the screen-half to be very slightly moveable in the up-and-down vertical direction, both in open and closed position? I'm not talking about inward and outward, but rather up and down on the vertical y-axis like from the ear speaker at the top to the mouth mic at the bottom. And I'm only talking about a millimeter of very slight movement if you hold your thumb down firmly or grab it with two fingers and try to move it.
