my new iphone broke

This is a user forum, you are not addressing apple here  just  fellow users

you can try contacting apple Support ->  Get Support (apple.com)

and or give them feedback -> Product Feedback - Apple

if it was me then I would read

iPhone Screen Repair & Replacement - Official Apple Support

Take it to a Genius Bar to have it repaired.

Genius Bar Reservation and Apple Support Options - Apple

And?
