Memory and Storage
The vivo S12 is available in three memory configurations: 128GB with 8GB RAM, 256GB with 8GB RAM, and 256GB with 12GB RAM. All versions use UFS 3.1 storage, ensuring quick data access and writing speeds. However, it is important to note that the device does not offer expandable storage via a memory card slot, so users must consider their storage needs when selecting a model.
