[Leak] One UI 7 to bring NowBar live activity, Galaxy AI notification summary

Published

on

Samsung One UI 7

One UI 7 could bring many iOS 18-inspired features such as Live Activity and AI-powered Notification Summary. In a recent development, a tipster revealed that the One UI 7 brings NowBar and Galaxy AI Notification functionalities.

NowBar – Live Activity

NowBar is seemingly Samsung’s codename for One UI 7’s Live Activity feature. It’s going to be a welcome addition to look at, especially for apps with frequent content and status updates, which go beyond the push notifications.

In iOS, Live Activities renders frequent information updates in glanceable locations. Recent iPhones also use Dynamic Island for glanceable activities. However, One UI 7 is said to be bringing it with a notification shade overlay.

Recently leaked videos showcased Live Activities like the feature on the lock screen. Remember the charging animation pill on the lock screen that had dynamic functioning? Expect more Live Activity to appear on your Galaxy with One UI 7.

Galaxy AI Notification – Notification Summary

Galaxy AI is said to add an AI Notification feature inspired by iOS 18.1’s Notification Summary. This AI-powered functionality will make it easier to understand important notifications instantly by prioritizing stuff as per user routine.

Apple Intelligence brings a Notification Summary feature to iPhones. It is aimed at reducing interruptions to focus only on the notifications that need immediate attention. Galaxy AI could add an AI Notification feature with similar functionality for Galaxy devices.

One UI may have a button to enable and disable the AI Notification feature. As the function leverages artificial intelligence, responses, and behavior may be misleading sometimes, which could put you in sudden trouble.

One UI 7’s Thermal Throttling key will unleash max gaming power

Published

on

Samsung Developers gaming

One UI 7 could come with a hidden key to disable Thermal Throttling. Samsung is working on its Android 15-based One UI software. A tipster revealed One UI 7’s hidden feature that will allow users to maximize gaming potential.

According to the info, One UI 7 carries a Developer options key that lets you completely disable Thermal Throttling. Before the recent removal, it was accessible on One UI 6 through a manual System UI Tuner trick.

Samsung is blamed for aggressively throttling performance in certain circumstances. Previously, the company rolled out an alternate performance management option in the Game Launcher/Game Booster app to bypass throttling.

The Labs trick somewhat reduces Thermal Throttling, but not a solution. Looking ahead, the One UI 7 would address the Thermal Throttling concern so Galaxy users can experience maximum power during long gaming sessions.

The key will let you completely disable Thermal Throttling. It is a better solution than the performance management option of Labs, which increases the thermal heating limit to lessen throttling during extensive usage.

Developer options usually contain a set of settings not preferred for general users. It is mainly for developers to test application behavior during development. However, the wise use of Developer options unleashes maximum power from hardware.

The feature is intended to be developed for flagship phones. The upcoming Galaxy S25 series would also have the key to disable Thermal Throttling. The modification will allow users to continue gaming with the maximum performance allowed by the hardware.

[Leak] Samsung greatly modified One UI 7 Beta, release awaited

Published

on

Samsung One UI 7

One UI 7 Beta continued to be modified in development as Samsung sets “later this year” release. While Galaxy users await the Beta Program to kick off, the company is making radical changes to the user interface and other aspects of the software.

IceUniverse claims that Samsung One UI 7 Beta has modified much with the version ending XJW. It is the latest version that has many changes in terms of UI and appearance. The leaker notes that the new build makes the previously leaked videos meaningless.

Samsung has reportedly brought significant improvements to the One UI 7 Beta. The upcoming software is “full of flexibility,” setting the stage for a grand entry to set a new standard of user experience on Galaxy devices.

While the tipster didn’t note specific changes, notable improvements are likely in animations and motion fluidity. The appearance may have not been revamped much as Samsung already altered that segment in many ways, many times.

One UI 7 XJW leak via Ice Universe

The latest version of One UI 7, XJW, makes the previously leaked videos meaningless, because this version has changed a lot and is full of flexibility, and the previous versions can be thrown into the trash.

Earlier, a YouTuber revealed the One UI 7 interface and features. The video showed many major changes across the user interface as compared to the build that Samsung showcased at CodeLabs after the SDC24 keynote.

Later, we’ve also seen the animation fluidity of One UI 7 in a leaked video. As compared to the One UI 6.1.1, the next iteration has smoother animations, however, the final version is likely to bring it even closer to iOS animations.
