I wanted to switch from the Note series to the Fold series last year.
But was told I couldn't do that and could only get another Note series phone.
Changed this year as they've stopped doing the Note series phones and was offered the option of getting the Fold 3.
This was obviously an exception due to that series of phone finishing.
You can ask Customer Support, but as there is still the S series going. I don't think you'd be eligible
