Samsung rolled out One UI 2.1 based on Android 10 for several Exynos 7870-powered devices earlier this year in April. However, the update didn’t include the One UI 2.1-specific software features that were introduced with the company’s flagship Galaxy S20 series. This prompted XDA Recognized Developer Astrako to release a generic Android 10 ROM for Exynos 7870-powered devices called H-ROM with the new One UI 2.1 features. With the Galaxy Note 20 series launch earlier this month, Samsung released One UI 2.5 with more new features and the software is scheduled to make its way to many of the company’s older flagships. However, Galaxy devices featuring the Exynos 7870 chipset have been left out once again. Thankfully, Astrako has now released a One UI 2.5-based port of H-ROM for these devices.
The latest version of H-ROM is compatible with seven Exynos 7870-powered Samsung Galaxy devices, including the Galaxy A3 (2017) and different variants of the Galaxy J5, Galaxy J6, and Galaxy J7. The base of the ROM is taken from the Galaxy Note 20 (SM-N980F) and it ships with a modified CSC from the Galaxy Note 20 that enables features like native call recording.
The ROM includes Android security patches for August 2020 and it’s completely devoid of bloatware and Samsung’s security software. There are some known bugs for each device, which can be found in their respective forum threads linked below. For those of you who want root access after installing H-ROM, the developer advises opting for the Canary version of Magisk as flashing the stable release on the current version of the ROM results in a bootloop.
