What's wrong with this picture that it wasn't approved? Can anyone say specifically?

Alien hands. & gibberish screen text.  😝

Machines make lots & lots of mistakes, especially with human anatomy and fine details. Always check AI quality & accuracy before you submit.  Fix all defects if you can, or discard the image & start over.

1-You likely use sharpenning AI, and distorted the fonts on the screen and device brand.

2-Even if you removed all the fonts, images on a screen can also be protected, I've shot a lot of similar images without defects like your image, and remove brand names and still get rejected.
