This is why it is often recommended to stay in AFC mode when using back button focus, since the main reason for AFS, which is the ability to focus and recompose, can be done by simply letting go of the button.

When you let go of that button, the camera stops all auto focusing in any mode and stays at the last setting. It's possible that there's some difference between the D3200 and the D3300. I've been trying out back button focusing (BBF) for a couple months now and appreciate the advantages.

The Nikon D3300 has various controls on the outside on the camera body.
