Hello, My question is rather simple. I need to know what all those pins that appear after you remove the back cover are used for. I guess that the ones just above the battery are used for NFC, but I have no idea about the others. I used this picture you took as a reference: https://d3nevzfk7ii3be.cloudfront.net/ig… Thanks in advance. Best regards, Ivan
They are pogo pins for all the antennas which are all placed on the inside of the back cover itself. All the flat gold traces one the inside of the back cover are antennas. The official name for spring loaded connector pins like this is pogo pins: http://en.wikipedia.org/wiki/Pogo_pin There’s 4 antennas in total: NFC antenna in the middle. GSM/WCDAM antenna at the bottom GPS antenna is the large one at the top. Bluetooth/WiFi is the small one at the top. This is documented in the Internal Photos.pdf from the FCC approval documents you can download here: https://apps.fcc.gov/oetcf/eas/reports/V…
