In the lifecycle of any important gadget, after the announcement and release comes the teardown. iFixit has gotten a hold of the Galaxy S10, S10 Plus, and S10e and has stripped them all down to their base parts. As usual, modern smartphone design is a mess of adhesive that is difficult to repair. The pictures are fun to look at, though!

In terms of actual components, the sensor is a thin, tape-like strip that gets glued to the back of the display. We've seen prototypes with a large fingerprint-reading area before, but for this first-generation commercial version, Samsung's fingerprint reading area is just a tiny strip. It's actually way smaller than a fingertip, which means you'll need to be precise about your finger position when you use it.

There are lots of heat-mitigation techniques going on inside the Galaxy S10. Like the Note9 and Galaxy S9, a large vapor chamber handles cooling the SoC and storage. The back of the display is coated in copper, allowing it to act as a big heatsink.
