Overview

• A leaked One UI 8.5 build for the Galaxy S25 Ultra shows the notification summaries interface and settings, but the feature does not function yet.
• The first-use pop-up explains the capability and a Manage apps page appears, though every app is listed by default and exclusions cannot be changed in the leak.
• Samsung is developing the tool to condense long messages and group conversations into brief highlights for quicker scanning.
• Reporting indicates processing will rely on Google Cloud, while the leaked description claims messages do not reach Google and the on-device versus cloud split remains unconfirmed.
• One UI 8.5 is widely expected to roll out with the Galaxy S26 series in January, with notification summaries joining Samsung’s expanding Galaxy AI features.
