We wanted to see if it was possible to eliminate the physical buttons on the front of the phone by using a capacitive button panel.

Disadvantages:

We made a test panel, shown above, that has buttons of approximately the size and pitch we need for the phone. Overall, the test panel works OK. It is, in fact, easy to accidentally trigger neighboring buttons. But it was interesting enough we'll go ahead and make another panel using our current button layout and see how it performs in the phone.
