I just replaced the charge port and whole new screen on my daughter's iPhone 7 plus yesterday. Everything works fine, except now when trying to make a phone call, there is no audio. The speaker button is grayed out, and there is no audio from any speaker and the person on the other end can't hear any voice. I'm hoping I just didn't seat one of the cables properly. Any ideas?

This is a common logic board issue in the iPhone 7 series. It is an Audio IC failure. The fix would require micro soldering.

Hello Dee!
So when replacing an iPhone screen, you have to make sure to transfer the old speaker onto the new screen! Have you done this? If not that would explain why you cannot hear anyone, and why the speaker button is grey.
If you completed this step, it could mean a cable is loose. Carefully making sure all of the ribbon cables are securely seated can potentially solve your issue. All of those cables matter!
Hope I helped!

Hi
Does the phone make any noise at all?
Eg playing music or watching a video?
