It has already been confirmed that the Samsung Galaxy S22 will use Snapdragon 8 Gen1 and Exynos 2200. However, Samsung will be able to use the Dimensity 9000 in high-end devices only in the second half of the year. That is, this processor most likely will not appear in the Galaxy S22 series. But we can see this chip in other flagship devices too.
Thus, Samsung will be the only Android manufacturer to use three flagship processors. Most companies will stick with Snapdragon 8 Gen1 and MediaTek Dimensity 9000.
