Optical Sensor S7
Since few days, my optical sensor don’t work, I can’t see my cardiac frequency.
I restarted my watch, but nothing.
I would like to know if an function exist on the watch or on the phone.
My last chance is a hard reset but may last… (I hope)
@deaquinogeorges It is not simply dirty?
@deaquinogeorges mine actually stopped working a few weeks ago. Ended up doing a factory reset.
