Hello.
Thank you for reaching out regarding your Samsung - 25.5 Cu. Ft. French Door Refrigerator with Filtered Ice Maker if both bottom drawers are freezer. Regarding your concern, the bottom left would be purely freezer; on the bottom right, you can use the cool select button option to set it to one of four settings: Freezer, Soft Freezing, Chill, or Cool.
I suggest you check this link to your user manual for further assistance. Please go to pages 19 to 20.
