Hi guys I just replaced my screen on my note 5 and everything on the phone is working but im not getting a network connection, My signal strength is -120dB i know thats bad. Im trying to figure out where the antenna for the cellular connection is i see the two wires that run from the mobo to the usb board but im guessing those are wifi any help would be appreciated i dont want to have to go back o the moto e ive been using.
