Samsung's yet-to-be-announced Exynos 7872 system-on-chip (SoC), which Galaxy Club believes could debut on the upcoming Galaxy A3 (2018), has been certified by the Bluetooth SIG, indicating that its release is right around the corner.
Information surrounding the Exynos 7827 is sparse
Not a lot is known about the mysterious Exynos 7872, other than that it bundles compatibility for Bluetooth 4.2. Rumors fresh out of China, however, suggest that it's a 14-nanometer hexa-core SoC that's equipped with a Mali-G71 GPU.
