Galaxy FaceTime

  Conversations shift, and so should your ability to move from a regular audio call to a video call. While you're on an audio call, tap on the FaceTime button on the screen, and the video interface will appear. You must then wait on the other person to accept the FaceTime video call to proceed. If they decline, the call will revert to an audio-only call.

  Animojis and Memojis are Snapchat-style face-tracking features native to Apple. You can use an octopus, robot, monkey, or another Apple-created Animjoi, as well as custom-created Memoji in your likeness, during a video chat on FaceTime. To use them, tap on the screen during a FaceTime call, then hit "effects" in the bottom left. Next, tap on the Animoji icon that appears. All of the existing Animojis will appear, as well as any Memojis you've created. Tap on one to test it out, and the other person will see it on you right away. Move your head around, smile, and stick your tongue out to see if it works well in the lighting you're in. If you're too close to the camera, it won't work, so play around with distance and speed until it works best. When you're finished, tap on the (X) button to go back to your video chat with your new face filter.

  If you're in a different country or region, you should change your location so that FaceTime can dial local numbers in your address book and make the process of contacting your friends and family much easier. First, open the Settings app and go into the "FaceTime" option. Tap on your Apple ID, then "Change Location," and hit "Region." If you've moved to a different region or are visiting a different part of the world, select it from the list that appears. Once you've chosen an area, tap on "Save" to use that location.

  FaceTime can be connected to your phone number, email address, or both, which means you can be contacted in several different ways. To select how you can be reached, open the Settings app and go into "FaceTime." Under the  You Can Be Reached By FaceTime At  section, select or deselect email addresses (you can choose more than one). You can also add more email addresses to choose from but not from these "FaceTime" settings.

  Keep it hands-free and use Siri  to FaceTime call someone in your contacts. Simply bring up Siri (either say "Hey Siri" or hold down on the Side or Home button) and say "FaceTime [Full Contact Name]." The FaceTime call will automatically be made after your command.

  Using FaceTime daily, or even weekly, for a prolonged amount of time can eat up your data quickly. You can use Wi-Fi (obviously), but if it cuts out, you'll be relying on cellular data to continue your video call — unless you ax FaceTime and mobile data compatibility. Open the Settings app, tap on "Cellular," and turn off the toggle next to FaceTime. FaceTime will now only work on Wi-Fi and not cellular data, so you don't have to worry about going over your limit.
