Pulse OX stopped working.

NOTE: I have contacted Garmin Support, and we troubleshot the watch and settings. And I'm to report back tomorrow if anything changes.

But In the meantime: this seems like a hardware issue, but it came about after a very specific use case ... so might be software related. Just wanted to see if anyone had experienced similar.

I went on a week-long canoe camping trip and wanted to use the watch for GPS as much as possible. I set it to battery-saver mode, and my Navigate, and Track Me activities used a power mode where GPS was enabled, but HR, Pulse OX, Bluetooth was off. All was good.

When I got home I took the battery saver off. HR and bluetooth are fine, but Pulse OX hasn't worked since. There were no events I'm aware of that could have damaged the watch. I was wearing it the whole time.

I guess you already tried the master reset to factory defaults, or did not you?

We tried a hard reset and the support agent double checked several settings with me.
after a day of messing around, it seems to sometimes do a successful Pulse OX measurement. I’ve tried multiple variations of wrist positions, both arms, varying tightness of fit, elevating wrist to different levels, trying it in the dark (to avoid ambient light interference), cleaning the watch and my arm. But I can’t get it to reliably take a reading. This wasn’t a problem before.

When my pulse ox doesn't work. I rotate the watch under my wrist. Where you can see all the bluelines of your vains. I have the idea that the watch can monitor that side better.

Just tried that. I can clearly see my veins. It didn’t help. My sensor must be flaking out.
