iPhone 13 Pro Pink Screen

Hi Nanine92,

Seems best to take your iPhone into an Apple Store and have it checked out.

A Genius Bar reservation is recommended

Genius Bar Reservation and Apple Support Options - Apple

If that is difficult, you can try contacting Apple online or by Phone.

There is a "Get Support" link to Apple at top right on this discussion page

Or

See a list of Apple phone numbers around the world.

Contact Apple for support and service - Apple Support2

If your country is not listed:

Apple Assistance:

Choose your country or region:

Choose your country or region - Official Apple Support

All the best :-)
