How to take portraits with your phone camera?

Question

Photo

Good afternoon. on the camera phone:
1. regular, f/1.8. 26mm
2. tele. zoom f/2.2. 50mm. 2x magnification without loss of quality
3. 17mm wide angle.
4. No more. But are there cameras better suited for portraits?

What is the best way to shoot head, half, full length portraits?
For example, on a regular camera, or on what they call a telephoto camera, or just shoot without bothering with a regular one? And then just load it into the program and correct the distortion.
Or go far and then cut.

Answer 1

Shoot with a tele-camera (the one with f / 2.2. 50mm) move away, keep your face in the center of the frame.
Then cut, yes.
Distortion is noticeable closer to the edges of the frame, so keep your face closer to the center.
