Hands-free selfies on your Samsung Galaxy S23: How to use palm gestures and voice commands to take photos

One of the most useful features baked into Samsung's Android skin - called OneUI - is the ability to snap photos without touching the buttons or the onscreen shutter button. Instead, you can use a palm gesture or voice command to take a selfie, which means you can set your phone up on a tripod, or rest it against a surface, frame yourself and take your picture without having to stretch awkwardly to reach your phone. Or, if you have the S22 Ultra or S23 Ultra, you can use the S Pen's shortcut button instead.
