Comment on ELI5: how do mobile devices know your movements?
Irremarkable@fedia.io 1 month agoSamsung phones used to be able to measure heart rate along with blood oxygenation. Not sure when they stopped, but I know one of my old galaxy's had it, either the 5 or 8.

I think it had to do with how the cameras and lights were oriented. I missed that one too. Pretty damn accurate.

Something like that, yeah. Didn't personally have an actual practical use for it, but it was certainly a nice thing to have.
