How to Answer Calls on Samsung Galaxy Watch 4

Name: Google Pixel Watch 4
Brand: Google
Availability: PreOrder
Rating: 4.8 (1250 reviews)

The Galaxy Watch 4 lets you answer and make calls directly from your wrist using the built-in speaker and microphone. Calls work best for quick conversations in quiet environments.

Answering Incoming Calls

When a call comes in, the watch displays the caller's name or number with options to accept or decline.

Accept: Swipe right on the notification or tap the green phone icon.
Decline: Swipe left or tap the red icon. The call goes to voicemail.
Decline with Message: Swipe up during an incoming call to send a quick reply like I'll call you back via SMS.

Making Calls from the Watch

You can initiate calls through the Contacts app, Phone app, or voice commands.

Using Contacts: Press the Home button and open Contacts, scroll to find the contact, tap their name, then tap the phone icon.
Using Voice Commands: Press and hold the Home button to activate Google Assistant, say Call Mom or Call Dad mobile, and confirm if the contact has multiple numbers.
Using the Dial Pad: Open the Phone app and tap the dial pad icon to manually enter a number. Voice dialing is usually faster given the small screen.

Audio Options During Calls

The watch speaker works for quick calls, but you have other options for better quality.

Watch Speaker: Adequate for quiet environments. Position the watch 6-12 inches from your mouth when speaking.
Transfer to Phone: During a call, tap the phone icon and select Switch to phone to continue the conversation on your phone.
Bluetooth Headphones: If you have earbuds paired with the watch, audio automatically routes to them when you answer. This provides much better quality and privacy.

Call Controls

While on a call, you can manage audio and access additional options.

Mute: Tap the microphone icon to mute your end.
Volume: Swipe down for quick settings and adjust the volume slider.
End Call: Tap the red hang-up button.
Keypad: Access the dial pad for navigating phone menus.

LTE Calls (LTE Models Only)

LTE models can make calls independently without your phone nearby.

Requirements: Active carrier plan ($10-15/month) from Verizon, AT&T, T-Mobile, or US Cellular.
Same Number: Calls use your regular phone number through NumberSync or DIGITS.
Best Use Case: Exercising or running errands without your phone while staying reachable.

Call Quality Tip

The watch speaker works best in quiet settings. For important or longer calls, transfer to your phone or use Bluetooth earbuds for better audio quality and privacy. Expect 10-15% battery drain per hour of active calling.
