What is samsung m20 s?

Sorry, as an AI language model, I do not have access to real-time information about products. However, I can tell you that the Samsung Galaxy M20s could be speculated to be an updated version of the Samsung Galaxy M20, which was released in 2019. If the Samsung M20s exists, it could have improvements to the battery life and camera features. It might also have a larger display and a faster processor. But again, without any official information, this is simply speculation.
