Instead of manually dialing phone numbers using the dial pad, you can use your People app to dial quickly and easily.
When you first turn on your phone and sign into a Google Account, any existing contacts from that account are synced with your People app. After that, all your contacts stay in sync automatically on your phone, another device, or a Web browser.
