When you are already on a call press add call then add another person to the call.

That's right, if you move the phone from your face, it will light up. On the phone screen there should be six options. Just hit Add Call. 

If this feature is greyed out this is because it needs to be enabled by your network provider.

add call doesn't always work, even for me
