iPhone 13 pro max white screen

Hi zarniwm,

Since the phone is frozen on a white screen, start by following the steps found here: If your iPhone won't turn on or is frozen

If the phone is still only showing a white screen after following those steps, we recommend reaching out to Apple Support so they can look into this in more detail and go through all the options to reach a resolution with you. You can do that here: Contact Apple Support

Take care.
