When you look at yourself in the mirror, or look at someone else from any distance, your brain re-interprets what it actually sees, so you can't tell that perspective distortion is making your nose look big & your ears look small.
As soon as you take a photo of that, your brain can no longer re-map it into 'reality' because it's just a flat image. That's why selfies look so bad - big nose, little ears.
The only way to fool your brain into thinking that what it sees in a photo is what you would see in a mirror, is to take the picture from at least 10-15 feet away. At this distance with a phone, you'll barely be taking up enough of the frame to consider it still a portrait, so ideally you'd need to crop the image or use a longer lens.
Note that even at this distance you will still see some slight distortion - your legs will look short.
There are several articles about this - usually explaining from a different perspective [no pun intended] to explain 'lens compression'
An example from FStoppers - How Lens Compression and Perspective Distortion Work containing a gif showing how this perspective distortion manifests. By moving the camera at the same time as changing the zoom, the subject's face is kept at the same proportion in the frame. The subject doesn't move.
This is an extreme example, probably requiring several lenses, as the shortest is 15mm [slightly shorter than even a phone] to 1000mm.
