[One Plus One] What are all those pins behind the back cover?

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:

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...

Everyone asking and wondering about fixing the pins on this and any other phone, the answer is yes. Luckily they're large single connections and aren't located in very populated spots on the board so you can easily just put flux on the single pad(add a tiny flat layer of solder if there isn't much remaining, then add a little flux) then simply place the pin on the pad and place the fine tip of your iron on the base of the pin, heating it up until the solder reflows then gently remove the iron leaving the pin in place to cool. Finally GENTLY clean it with a small amount of alcohol and a qtip.

If you ripped the pad off with the pin you'll have to scrape off some of the solder mask to expose the trace(again, patience is key here, you don't want to be rough and shave off the copper trace as well) in order to make the connection, and probably use a tiny bit of epoxy to hold the pin in position. Tons of old devices have the exact same pins to be salvaged from and work well for practice before the real deal.
