Samsung currently uses two models of chips, which it complements the flagship smartphones. In models designed for the European market, use the Exynos chip, while the models intended for the us market, coming with Snapdragon. In the future this should change. Already in 2021 Samsung smartphones will only use Exynos processors.
The problem is the cost of the Qualcomm Snapdragon processor, which every year becomes more and more expensive – Samsung does not want and can not afford such costs. Therefore, the Korean manufacturer will rely only on its own decisions.
This information comes from a source that in the past were given verified information about the plans of Samsung.
