I can't figure out how to close my samsung account so I can deactivate my old samsung phone and activate my new samsung phone. Could someone please tell me how to close my samsung account?
I'm not sure what is it that you are trying to do. To deactivate a prior phone you only have to Factory reset that phone. Why would you want to delete your Samsung account makes no sense to me. Again if you want to remove your information from an old phone do a factory reset and don't sign on to the phone again.
You don't need to close your Samsung account to deactivate your old phone. Just wipe and reset your old phone, delete reference to it on your Samsung account and add you new phone to existing account. Done.
