What I really don’t like: The skin temperature sensor doesn’t work yet

The number one reason I’d suggest you chuck the Galaxy Watch 4 in favor of the Watch 5 is to get access to that built-in skin temperature sensor. But unfortunately, it’s currently dormant. Samsung Health does not make use of it yet.
I have a condition that raises my internal body temperature slightly every month. I hate having to locate my kid’s in-ear thermometer to check it. I would love for nothing more than to flip my wrist up and check in to see if my body is doing the thing I expect it to do. Anyway, I wear a smartwatch even when I’m not moving much because I want aggregated data on my internals.
Now that the Watch 5 is available to buy, I’m hoping Samsung Health finally gets support for this feature.
