Samsung ONE UI 5.1

It’s only been a couple of months since Samsung released the most awaited One UI 5.0 firmware update based on Android 13. Earlier this month, the electronics giant launched the latest flagships – Galaxy S23, S23+, and S23 Ultra featuring One UI 5.1 firmware with tons of refinements and feature upgrades. Today, Samsung rolled out the first round of OTA updates featuring One UI 5.1 for the previous-gen flagship smartphones including the Galaxy S22 and S21 series.

While One UI 5.1 is the new major upgrade, it is still based on Android 13 but brings a ton of new features, system improvements, and quality-of-life upgrades. For one, it brings major changes to the Samsung camera and the Gallery apps.

The OTA is reportedly live in Europe for the Exynos variants including Norway, the United Kingdom, Spain, the Netherlands, Finland, Germany, and more to follow later today. The OTA will soon roll out in South East Asia including India in the coming days.

One UI 5.1 OTA weighs a whopping 2GB in size and brings new February 2023 security patches with firmware build EWAF. It is is available for all four variants including the Galaxy S21, S21+, S21 Ultra, and S21 FE.

The update will soon be rolled out in the United States for Unlocked Snapdragon variants, as well as carrier variants when the respective carriers release it.

Many stock Samsung apps including the popular Good Lock plugins, Samsung Good Guardians, and Expert Raw have been updated in support of Android 13.
