Error installing ios 13.5.1 on new iPhone
Just purchased a new 128GB iPhone 7 from AT&T. Connected new iPhone to old iPhone to transfer data. New iPhone downloads ios 13.5.1. After the download completes "Install Now" is displayed with whirling circle next to it. The phone is hung right there. I've tried it three times, always the same result. Phone is fully charged and plugged in. Any ideas?
