From my observation, the Camera phone from Apple has gone a long way when it comes to creating flattering portraits shots with great depth of field. This was previously possible only using an SLR camera with a high speed lens attached.
The Iphone also produced great shots everytime without adjustments unlike the DLSR where a certain level of photography skill is needed.
But the greatest advantage of the IphoneX is the ability of the user to take a portrait shot of himself without a tripod or an assistant. Now that's something I still can't figure out how to do with my DSLR.
