One advantage of png is that it will handle transparency. Don’t know if the phone leaves the area outside the subject transparent. If it does, placing it on a layer above a desired background would show the subject over the background. You have to use an editor that handles layers.

As DirtFarmer stated. The image will be a PNG, Although when saved to your phone it shows a white background, that white background will not show when you open the image in Photoshop. The background then will be shown with transparent pixels.
