I haven't even owned the Active2 for a year. It was a great product until it stopped working. I sent it in for repair, everyone on the phone has been kind but the policy of "this watch is water-resistant not waterproof" is absurd. If you advertise that it can go in a pool, a shower shouldn't kill it. I had used the Water Mode every time, I've shaken the water out of the speaker as instructed.
They sent me a repair bill of $220, exactly what a new Active2 retails for. Why in the world would I risk another $220 on something that might last a year, might not?
Very strongly considering not even looking at another Samsung Watch.
The rear cover is only held in place by what looks like a silicone compound.
I would be interested to know what others in the Samsung Community have to say about your issue?
