As in previous versions of Samsung's flagship phone from Galaxy series we can expect that Samsung Galaxy S9 will be released in two versions for different regions of the world. Version with Qualcomm Snapdragon 845 will probably be dedicated to the United States and China. Rest of the world will receive version with new Exynos processor, and Samsung confirmed that they plan to present their new processor on 4th of January.
New Samsung's processor will probably be named Exynos 9810. What's more, first phone in which it will be used, so Samsung Galaxy S9 already received FCC certification in the United States. Unfortunately, information related to this phone hasn't leaked, so we will probably have to wait until the MWC 2018 for confirmed device specification, where we expect the official presentation of the Samsung Galaxy S9.
