Bad Bluetooth Range or GPS accuracy on Iphone SE after repair ??

After a repair of Wi-Fi coverage where the Wi-Fi antenna was changed I discovered that the problem was solved but I had lost a lot of distance in Bluetooth transmittions and the GPS had also lost much accuracy and it was slow to fix the satellites, after several attempts to reinstall the Wi-Fi antenna and review the connector I discovered that there was another antenna that need to be positioned over the base motherboard during assembly, this additional antenna starts from a washer that is fastened by a screw, if the washer is positioned below the motherboard by error the connection is lost with the antenna and we lose quality, here you are some pics.
