I’ve replaced the WiFi antenna on my I phone 6 and now my finger I’d sensor doesn’t work, whenever I try it just says unable to set up finger id

Hi Gary! I recommend you open up the device once more to check to see if there is poor connection with the fingerprint sensor. Try disconnecting and reconnecting it. Then restart the device before using it. You should also check for home button flex. That is a common issue and can cause Touch ID to function improperly. Hope all goes well!
