One UI 6.1 will be an exciting update for anyone who owns a flagship Galaxy smartphone or tablet that launched in 2023, as those are the only devices that are eligible to receive the Galaxy S24's AI features as a part of that update, at least right now.
When Samsung announced the One UI 6.1 update for its 2023 flagships, the company added a footnote saying that some Galaxy AI features from the Galaxy S24 “may not be available in previous generation models”, but it looks like that footnote doesn't apply to the Galaxy S23, Galaxy Z Fold 5, and Galaxy Z Flip 5.
A screenshot shared by Twitter leakster Ice universe reveals that the Advanced intelligence menu on a Galaxy Z Fold 5 lists all the AI features that can be found in that same menu on a Galaxy S24. Samsung has also added a description for Circle to Search in there so users know the feature exists (the Galaxy S24 series has Circle to Search but Samsung doesn't list it with the other features in the Advanced intelligence menu).
The Galaxy S23 FE may be the only device to not get all Galaxy S24 AI features. While it launched in 2023, it features the same Exynos and Snapdragon chips as the Galaxy S22 series instead of the more powerful Snapdragon 8 Gen 2 chip that sits inside the non-FE Galaxy S23 models, the Fold 5 and Flip 5, and the Galaxy Tab S9.
The One UI 6.1 update will start rolling out sometime later this month for the Galaxy S23 series, Fold 5, Flip 5, and Tab S9, but the rollout of the update is expected to spill over into April for most markets. Other eligible devices may also get One UI 6.1 starting in April, though this is not confirmed.
