iPhone XR (modded, 18 Pro style)

This is an iPhone XR, but with an iPhone 18 Pro housing. All working great, except: - Rear camera is intermittent but front camera works perfectly - NFC/tap to pay. I think I know why, and it might be fixable via one quick soldering job. iOS 18. Will fully reset and remove Apple ID. Aside from the above, all of the buttons, silent switch, speakers, screen, face id, wifi, Bluetooth, wireless/wired charging, flashlight, etc. work. No carrier lock or activation lock.
