Samsung has also confirmed the list of eligible Galaxy devices to receive the One UI 2.5 update, but all of them are flagship smartphones with strong Exynos chipsets. Samsung didn’t include the Exynos 7870-powered devices in the eligible device list.
Thanks to XDA’s Astrako, who released a One UI 2.5-based port of H-ROM for the Exynos 7890-powered devices. The latest H-ROM is compatible with 7 Exynos 7870-powered Galaxy devices, including the Galaxy A3 (2017) and different variants of the J5, J6, and J7.
The ROM is based on the international 4G variant of the Galaxy Note 20. Along with many new features, it also comes with the August 2020 security patch. You can download the H-ROM for your Exynos 7870-powered device from the given link below.
