I just got the new Samsung Galaxy 4 Classic. I have had it a little over a week now. My issue is it is putting a burn mark on my wrist where the sensor touches. I have my watch monitor all day to monitor my activity, heart rate, stress etc...
After a few days, my wrist started burning. (Please see the attached photos) I took the watch off for a few days and put on some coconut oil, and Epsom salt and it started to heal. What's left is a perfect circle that matches the very inner circle of the sensor.
This is very concerning to me as I wear normal watches every day and this does not happen. This seems like a laser issue with monitoring.
After two days of not wearing the watch and putting on treatment
My father had a problem similar to yours and he found to be allergic to the bracelet composition.
It might be possible that your skin has a reaction to the infrared wavelenght of the sensor.
Do you feel heat coming from the watch back?
Have you used any other smartband or smartwatch prior to this one? Any known reaction?
It appears like a heat or sunburn mark.
I have the same issue as @B00TiKi.
I had been wearing my Galaxy Watch 3 for a year without issue but since receiving and wearing my Watch 4 Classic, I too have a mild burn mark on my wrist where the sensors sit.
It would be interesting if more owners could come forward and say if their experiencing the same, so Samsung could trace possible issues or at least identify a pattern (health issues, skin type, others).
