Any way to redeem a promo code with non Samsung device

A dev sent me a free code for a watchface. Even sent directions but i have a Nexus 6p and i can't for the life of me find anyway to redeem it

I had this issue on my S2 when I had an LG V10 I don't have the S3 yet but I never found a way to put codes in... I hope they have fixed this even though I have a Samsung phone now I think everyone should be able to get discounts and freebies!
