My screen on I phone is way magnified

Hi, sorry to hear about the issue you're having with your iPhone 7 Plus.

First, please try to understand that everyone on these forums are users, just like you; we aren't actual Apple employees. Sometimes it takes a bit of times for someone to get back to you about an issue, especially if it's later at night. As long as you're patient, someone is bound to help you out.

From what I can tell, you might have the Zoom accessibility feature turned on. To turn it off, double tap on your screen with two fingers. Check out this guide for more information: If your Home screen icons are magnified on your iPhone, iPad, or iPod touch - Apple Support

Hope this helps.
