How to make conference call from Lollipop?

[Sergei Popov]

Hi.
I am having Google Nexus 4 device. Recently, I have received the Lollipop update and updated my smartphone to Lollipop. Now I am not able to make conference call from my smart phone which was possible before upgrade. Any suggestions or Fix?

Thanks,

During a call, on the Dialer screen, tap the icon that looks like a phone with a plus sign. This allows you to add a caller to the call.
