Hey there, Mutan2!
Welcome to the Apple Support Communities. I understand that your iPhone 7 updated the iOS software, and now you're not able to advance in the setup. It's stuck at a screen presenting you with three options: Accessibility, Emergency Number, and Cancel. I'm happy to help.
Based on what you've described, I would first suggest restarting your iPhone: Restart your iPhone - Apple Support. If restarting doesn't work, try a forced restart: Restart your iPhone - Apple Support.
If the issue continues after that, don't hesitate to respond back. If you do, please give some additional information about your issue. For example, what happens immediately before you get to this screen? If you tap cancel, what happens?
Best!
