I have always enjoyed taking things apart to see how they worked, so I watched the 2e disassembly video on YouTube and followed along. I also have an associate’s degree in electronics, so I could tell what some of the parts were under the hood (I think). With the back case and top and bottom covers off and the phone lying on it’s face, I can see a thin black wire on the right side of the phone running between the top and bottoms PCBs. Is that the antenna, and if so, is the antenna shared for WiFi and cellular or am I looking at it all wrong?
Edit: It’s been a while since college, so I researched modern cellular antennas. I realize a LOT has changed! I withdraw my question and wish you guys the best of luck.
