Samsung will reportedly drop its Exynos chipset from the Galaxy A18 lineup. The 4G variant of the phone is said to use a MediaTek processor, while the Galaxy A18 5G could feature a Qualcomm Snapdragon chipset. The 4G variant of the Galaxy A17, for comparison, has a MediaTek Helio G99 chipset, while the 5G model is equipped with Samsung’s own Exynos 1330 SoC. The 4G-supported model is said to go official first, followed by the 5G model months later.
