A quick photo opportunity can disappear while you look for the Camera app. Setting up the Side button gives you a handy shortcut for everyday pictures, product photos and work notes.
Set up the camera shortcut
Open Settings.
Choose Advanced features, then Side button (sometimes called Side key).
Open Double press and enable it if needed.
Choose Camera. If your phone offers a further action, choose Open Camera. Older menus may show Quick launch camera.
Press the Side button twice in quick succession to try it.
Check the result
The Camera app should open. If another app appears, revisit Double press and check the selection. Use two quick presses rather than a long hold.
If your menu looks different
Search Settings for Side button or Side key. Features depend on your Galaxy model and software; follow the labels on your device. Camera access from a locked phone can have restrictions.
