I'm on my third Epic... before I finally found a good one The first two had problems with gaps between the top and bottom halves on the slider. First one had a gap as thick as a dime; the second one had a gap as thick as a quarter. On both of them, the two halves would click / slap together as you touched the screen. The first one also had dim and/or unresponsive menu buttons (along the bottom) as well as a camera issue. The third device has no gap issues, buttons well lit and responsive, and the on/off, volume and camera buttons are also MUCH better than the other two devices. The third phone's buttons 'click' much better; more travel and more positive engagement.
