Wild rumor: Xiaomi trying to fit a MFT sensor inside a future flagship smartphone!

As you might have heard the latest Xiaomi 13 smartphone uses a large 1 inch sensor. I now got a wild rumor from a source, saying that Xiaomi is trying to fit a full Four Thirds sensor inside their next flagship. Basically this would double the size of the 1 inch sensor which to me sounds like a super challenging task. But if they pull it off it would be simply stunning to have a smartphone with something like a OM-1 sensor inside!
