Download Galaxy S20 One UI 2.1 ROM Port on Exynos 7870 Devices (Galaxy A3, J7, J6, J5)

If you have a Samsung Galaxy device with the Exynos 7870 chipset, then you can download the ported Galaxy S20 ROM based on the One UI 2.1 firmware. Samsung announced the One UI 2.1 update, which is the latest version of the firmware, a few months ago. It is an improvement to the already great One UI 2.0. The new firmware comes with an improved camera app and additional camera modes, improved gallery experience, new keyboard features for improved typing experience, Quick Share, Music Share, and additional stability improvements.

As expected, Samsung has released the One UI 2.1 firmware update to all recent flagship devices. Surprisingly, Samsung also released the update to the Galaxy J6, which sits at the mid-range phone segment. The Galaxy J6 comes with the Exynos 7870 chipset, the same chipset as some other Samsung phones like A3 (2017), J7 and J5. Even though these devices have the same chipset, they have not received the new OneUI 2.1 update.
