Samsung Galaxy A54 Receives One UI 7 Update with Android 15: Features, Build Info & Rollout Details

Samsung Galaxy A54 Gets Android 15-Based One UI 7 Update in South Korea

Following the recent rollout of the One UI 7 update for the Galaxy A55, Samsung has now started pushing the Android 15-based One UI 7 update for its popular Galaxy A54 smartphone. The update is initially rolling out in South Korea and is expected to reach more regions in the coming days. Packed with fresh features, a redesigned user interface, improved customization options, and performance upgrades, One UI 7 aims to elevate the Galaxy A54 experience to a whole new level.

In this blog post, we dive deep into the update details, what's new, how to install it, and what Galaxy A54 users can expect globally.

📱 Update Overview: Android 15 x One UI 7 for Galaxy A54

The latest One UI 7 update for the Samsung Galaxy A54 (also known as Quantum 4 in Korea) comes with build version A546SKSU9DYD7. It is based on Android 15, Google's next-gen operating system, which is currently in beta for Pixel devices and is now making its way to Samsung’s mid-range lineup via One UI.

The firmware weighs around 3.4 GB, signaling a major software upgrade. This means it’s not just a routine update—it brings significant changes both under the hood and on the surface.

🌍 Availability: Initial Rollout in South Korea

As of now, the update is live only in South Korea. Samsung often initiates its software rollouts in its home country before expanding globally. This staged rollout strategy ensures that any critical bugs can be identified and resolved before reaching a broader user base.

If you own the Galaxy A54 (Quantum 4 variant) in South Korea, you can download the update by navigating to:
Settings > Software Update > Download and Install

📌 Note: This is an initial rollout. Some users may receive the update immediately, while others may have to wait a few hours or days as it gradually reaches all models.

🎨 What’s New in One UI 7 for Galaxy A54?

Samsung’s One UI 7 is more than just an Android version bump. It introduces a suite of new features and interface improvements designed for personalization, ease of use, and a visually pleasing experience.

Let’s take a look at the key changes and enhancements:

🔄 1. Refreshed User Interface

One UI 7 introduces a modern and refined UI, giving Galaxy A54 a fresh visual identity. Some of the noticeable changes include:

• Updated App Icons: More rounded and colorful icons with a polished look.

• New Color Schemes: Better integration with Material You theming for system-wide consistency.

• Smoother Animations: Enhanced transitions and animations across the OS for a fluid user experience.

🔐 2. Enhanced Lock Screen with “Now Bar”

A major highlight of One UI 7 is the addition of the “Now Bar” on the lock screen. This interactive bar displays real-time updates such as:

• Ongoing workout stats

• Media playback info

• Navigation directions

• Live notifications

The lock screen is now more customizable than ever. Users can tweak clock styles, add custom shortcuts, and choose widgets that offer at-a-glance information.

📲 3. Vertical Scrolling App Drawer

One of the most requested changes—the vertical scrolling app drawer—finally makes its way to One UI 7. Instead of swiping horizontally, apps are now accessible via vertical scroll, similar to Pixel and stock Android UI. This offers a more intuitive navigation pattern and reduces app searching time.

🧩 4. Widget Enhancements

Widgets get smarter and more functional in One UI 7:

• Stacked Widgets: Group multiple widgets in one place and swipe between them.

• Smart Suggestions: One UI can now suggest relevant widgets based on your usage habits.

• Resizable and Customizable: More freedom in widget resizing and placement.

🗂️ 5. Larger Home Screen Folders

Samsung has increased the folder size, allowing for larger folder previews and quicker app access. This change is aimed at users who prefer grouping apps into categories, improving both usability and aesthetics.

🧑‍🎨 6. App Design Updates

System apps like Phone, Messages, Settings, and Calendar now sport a redesigned interface. With cleaner layouts and better use of screen space, these apps feel more modern and aligned with Android 15’s design philosophy.

🛡️ 7. Improved Security and Stability

Alongside the visual upgrades, One UI 7 brings the latest Android security patch (April or May 2025, depending on rollout schedule). This patch strengthens the device against potential vulnerabilities and improves overall system stability.

Key improvements include:

• Enhanced privacy controls

• Granular app permissions

• Optimized battery and background process management

• Faster and more secure biometric authentication
