I damaged the connector for the top antenna on my LG V20 during screen replacement but I am unable to find a supplier for the part. I am not even sure what to call it and was hoping someone might know as I cannot connect to my wireless carrier since the phone repair. The part, a sticker which I believe connects the top antenna to the bumper, is circled in red in the image I linked.
