Although relieved of its many cameras, this board still feels like it's carrying some extra weight.

We pry off this mysterious green rectangle—which turns out to be a Qualcomm QTM052 mmWave antenna module.

"Millimeter wave" refers to RF signals with wavelengths measured in millimeters (24 GHz to 100 GHz). It offers super-duper fast download speeds, but can't travel long distances or penetrate walls very well. TL;DR: YMMV.

And one more thing: more board! Looks like Samsung took a note out of Apple's playbook and stacked their motherboard for maximum space savings.

We've been down this road before—and with a little help from our hot air station, we quickly carve through the vias and separate the boards.
