LG G4 antenna mod?

[AC Question]

OK, on my LG G4 when you remove the battery cover there's a spot where there are 2 small contacts that make contact with the rear cover. I assume this is the antenna on the rear cover contacts. Now, after looking closer there's actually 4 contact points there and 2 are taped over. If a person would remove the tape and allow all 4 contacts to touch would I see signal improvement or??? Thanks guys n gals!

I believe that is the NFC antenna. Im having signal issues after replacing a screen and am searching for info on the cell radio antenna myself
