Chosen Solution

hello please, i have a problem with iphone xr.  nfc didn’t work after the housing change.  so I thought the coil would be damaged, I replaced the coil with a new one and it still doesn’t work.  is the nfc antenna connected to the bottom antenna?  because I’m partially damaged here.  I’m running out of ideas …

The NFC antenna is connected to the TOP antenna, no use fixating on the bottom side.
