I want to ask how many of you guys have "waterwave" on your touch screen when pressing it. Mine does and I'm thinking if I should go ahead exchange it. People in xda-developers found out that 5 out of 6 touch he has owned got this problem (I believe it's the GSM European version which was released half a year ago).
The problem is basically you can see water wave like brightness change when press the screen. This is normal on non-touch LCD but touch screen should not have it. My friend's 6700 and my old mogul don't have it, no matter where you press it, the brightness is constant and no "water wave".
This is how it looks like:

BTW, mine was manufactured on 10/27/07, if you have or don't have this problem, can you identify the production date please? I wonder if it's related to the earlier batch defects. Thanks.
