I had the gear S2 watch and bought a newer model so deleted it from my account and gave it to my brother in law.
When he turns it on, a screen comes up that the reactivation lock is on and sign into samsung account to remove it.
It's not listed on my account anymore and we're not able to turn it off.
Does anyone have any ideas please? I've not changed any details of my Samsung account so if it was still registered to me, surely I would be able to turn it off?
