Gear S3 sensors all stopped working

[Bungles976]

A couple of days ago I noticed that the steps on my gear s3 weren't updating, just assumed it was an issue with Samsung health not syncing with my phone or something.

I then realised that my sleep hadn't been getting tracked and then with further investigation found the heart rate monitor and GPS had all stopped working.

All software is up to date, tried a soft reboot and restoring to factory settings and hasn't worked...

Now call me cynical if you want... but all this happened 2 years and 1 day from purchase just after the warranty has run out 🤔

@Bungles976: Regarding the Heart Rate Monitor, can you try opening the Samsung Health app on the watch, rotating the bezel to access the Settings screen > Tap the 3 lines > Auto HR, and tap the switch to activate it to see if this helps?
