Sorry about the wrong placement of my post, and thanks for correcting it.
You are absolutely correct about the touchscreen. I had been rotating the phone counter clockwise to get to landscape mode. That effectively moved the defective area to the top right portion of the screen and out of the keyboard area. However, when I rotated the screen clockwise from portrait to landscape, the defective area was in the bottom left corner of the screen and within the keyboard area. In this position, I continued to have trouble with the keys that fell within the defective area.
Thanks for helping me diagnose the problem. The company I bought it from said they would give me a refund.
