Touch ID and Earpiece not working after screen replacement

My sister gave me her iPhone 6 and the screen was cracked. I replaced it like I have many other iPhone screens before. Powered it down and detached the battery cables before disconnecting anything else. I replaced the screen and reattached the battery and powered it on. Everything works great except when I get a phone call I can only hear if I put it on speaker and it keeps telling me the Touch ID is not available on my iPhone. I redid the entire process, double checked EVERYTHING and both still do not work. My front camera and sensors work so the cable isn't damaged. Any advice?
