As of now, the Galaxy S21 and Galaxy Z Flip 3 series are receiving limited Galaxy AI features.
The changelogs for these phones only mention the Circle to Search feature as part of the One UI 6.1 update. Meanwhile, the Galaxy Z Fold 3 will apparently get more AI features, including AI-generated wallpapers and AI-generated image editing.
These Galaxy AI features are implemented by Samsung through the One UI 6.1 update and play an important role in the Galaxy S24 experience. Samsung released One UI 6.1 with Android 14 and Galaxy AI for the Galaxy S23 series before rolling it out to the Galaxy S22 series. But the company isn't done with everything yet as the update has been spotted rolling out to the Galaxy S21 series and some of the company's previous generation foldable phones, specifically the Galaxy Z Fold 4, Galaxy Z Flip 4, Galaxy Z Fold 3 and Galaxy Z Flip 3.
This update is currently rolling out to the Galaxy S21, Galaxy S21 Plus and Galaxy S21 Ultra, however the Galaxy S21 FE is not included in this series. South Korea was the first region to receive the update, and it's no surprise that the update will come to other markets. Thus, even the high-end Galaxy S smartphones of 2021 will attend Samsung's AI party.
The update is version F936NKSU2FXDC and weighs in at 2.8 GB. To install the update, users should go to Settings > Software Update > Download and install.
