I have just received my 2nd inc2, after too many problems with my x. I'm having problems answering my phone. I can't unlock it to answer the call, or nothing happens when I hit answer or even decline, BUT other people can answer it. Out of about 20 calls I was able to answer 3-4, all other calls were able to be answered by my co-workers. I un-installed advance task killer. It seems to have helped a little, but still missing some calls, or takes about 5-8 try's to answer.
