Are there additional Call Answer and End options on my Samsung Galaxy Note® II?
See below for additional Call Answer and End Options.
Open the Phone application, and touch Menu > Call settings > Answering/ending calls. You can set your device to answer calls using the Home key by marking the checkbox next to The home key answers calls. You can also set your device to end calls using the Power/Lock key by marking the checkbox next to The power key ends calls.
In addition to using the device keys, you can answer or reject calls by using your voice. Place a check mark next to Voice control. If Voice control is not already turned on, touch the slider to turn Voice control on and touch OK.
Note: You can also access Call settings from the Home screen. Touch Menu > Settings > My device > Call .
