What is samsung s23 plus?

As an AI language model, I do not have access to current information on upcoming or unannounced products like the Samsung S23 Plus. However, based on previous Samsung releases, it is possible that the S23 Plus may be a new iteration of Samsung's S series of smartphones, with possible improvements in display size and resolution, camera technology, processing power, and battery life. It is also possible that it may come with newer software and operating system, as well as new features such as improved biometrics and wireless charging capabilities.
