I want to like the Galaxy Ring but the O2 sensor makes incorrect low readings while I'm sleeping. I've seen readings as low as 71%. Samsung needs to make a fix for this. I only purchased the ring so I wouldn't have to wear my watch to bed, but it is worthless like this.
How tight or how loose is your ring on your finger? I had a similar problem with my watch because it was too loose on my wrist. Could that be the same problem with your ring?
