Comment 3 for bug 1392437

Some user testing feedback on this one:
"The new design caused issues in answering phone calls, because:
- no clear visual cue to indicate how to answer a call, and as a result, testers failed to answer calls. They had to call themselve to figure out how to answer a call.
- while testers appreciated such design reduced the risk of accidentally answering/rejecting an incoming call, the swipe gesture to activate was harder to perform than a tap, especially it was unclear to testers the exact position where they should start the swipe gesture.
- the high placement of the buttons reduced their accessibility (particularly when using one hand). "
