Top half of Evo not as touch sensitive as bottom half

Was using the multi touch visualizer app and was lightly swiping left to right near the bottom of the screen and then the top of the screen and noticed it
wasn't registering my finger as well near the top

Think I found a solution. To improve the registering of my Evo I did a touch screen calibration. To do this go to menu from the home screen....settings...language and keyboard........touch input....text input.....calibration tool. Do the test and run multi touch visualizer to verify. Think it helped a little
