I am trying to figure out what these are for. Can anyone help or point me to the relevant documentation?
Can I / should I have these repaired?
My phone works, but I have mediocre signal and an intermittent GPS reception.
thank you for the reply.
So the square under the battery is the nfc-antenna , interesting.
There are 3 traces on the back of the body. Not on the cover, under the cover on the inside. See picture above.
1-Above the battery at the side of the buttons. This one looks fine.
2-Between the SD-card and the camera, this is the largest pattern and this has chipped off in several places. (it seems pieces stuck to the back cover when I removed the back cover. )
3-A small trace at the bottom, next to the USB-port. This is also damaged on my phone.
Yes the top ones look like antenna but real antenna are usually solid wires.
The first one I mentioned is only a logo
I’m becoming more thoughtful that they are just overlays as they all have small points that look like they are for testing, so the painted lines could just be indicators. So they may not be conductive traces.
