How to fill in the phone number quickly?

When you turn on phone number sharing, it allows Google to show you a screen that lets you choose a phone number to share when a third-party app requests your phone number. This feature is useful when signing up for new accounts, verifying identities, or filling out forms in apps and websites. Reduces the need to manually enter your phone number.

1. Go to the [Settings] APP on your phone;
2. Slide down the screen to tap [Google];
3. Tap [All services];
4. Slide down the screen and go to [Phone number sharing];
5. Turn on [Phone number sharing].
