I have a Nexus S device (model i9023).
My current earpiece is torn - the wires are cut, and the body could not be screwed out because the specific body's screw is stuck. However, I can gently replace it without breaking the body.
I see a "HF" connector connected to the left of what I see in the picture of the earpiece unit.
To be more specific, I took some pictures of it, since I can't get the data from fixit.
Here's a picture of what dealers are selling in eBay. This picture is pretty descriptive.
All dealers provide a unit containing the earpieace speaker as seen upwards, a proximity sensor as seen below and the connector to the motherboard, to the right.
This is what I saw in fixit: as you can see upwards, there's another group of wires (orange) to the right of the proximity sensor, which doesn't exist in the seller's unit.
The pictures I took of my device shows exactly what I mean:
This "HF" wires down there doesn't exist in the units for sale
Don't mind the fact that in my pictures there's no speaker, its because its been torn. that's the reason why I was wandering around thinking of buying a new EM-Tech EME1511AFRC replacement unit in the first place...
So does anyone know what's that HF and what am I losing if I buy a new unit without it?
