Intermittent Touch Responsiveness

http://forum.xda-developers.com – I have a Xoom WiFi and have some issues with the touch. It ALWAYS registers taps, but I have issues with press and hold as well as dragging. The tricky thing is that it doesn't happen consistently. I researched it a bit and popped my Xoom open to take a look. I put tape under the ribbon of the digitizer controller and a note card piece under another. I also added a piece of foam on top of the chip to secure it in place. That made the problem improve some. Now it works perfectly most of the time but sometimes it doesn't press and hold for more than half a second or drag more than an inch or two (HowTos)
