It seems like you're asking about the Oppo Reno 12FS 512GB DS. However, as of my latest available data, there isn't an official Oppo model by that exact name (Reno 12FS). You might be referring to a different version or model in the Oppo Reno series, such as the Oppo Reno 10x Zoom, Oppo Reno 4, or another.
Oppo typically releases phones with various storage options, such as 128GB or 256GB, and sometimes offers a dual SIM (DS) version.
Could you provide more details, or do you mean another model like the Oppo Reno 8 Pro or Oppo Reno 12 series if available? I'd be happy to help you with more specific information!
