One UI 7 Update: Regions and Models Covered

The Galaxy S21 FE (Fan Edition), known for blending flagship features with affordability, is now enjoying the benefits of Android 15. The update is being delivered to both chip variants:

Snapdragon variant (model number G990B2)
Exynos variant (model number G990E)

Users across Europe, India, and Indonesia are among the first to receive the update, with more countries expected to join the rollout in the coming days. Samsung is known for its phased rollout strategy, ensuring smooth delivery and reduced risk of bugs or failures during updates.

Firmware Versions and Update Size

Here are the exact One UI 7 build versions you can expect based on your device chipset:

Snapdragon version: G990B2XXUBHYDB
Exynos version: G990EXXUDGYD4

The update package is approximately 3.5GB, so it’s recommended to connect to a stable Wi-Fi network and ensure that your phone has at least 50% battery before starting the installation.

What’s New in One UI 7 Based on Android 15?

Samsung has gone all-in with One UI 7, incorporating both Android 15 core enhancements and exclusive Samsung UI features. Here’s what Galaxy S21 FE users can look forward to:

1. Vertical Scrolling App Drawer

One of the most awaited features, the app drawer now scrolls vertically instead of horizontally, making navigation more intuitive and Android-like. This change improves accessibility and feels more natural, especially for users switching from stock Android or other OEM skins.

2. Redesigned Icons and Visual Aesthetics

The UI now features more minimalistic and modern icons across all system apps. Visual consistency has been improved, giving the system a refreshed and professional look. These changes create a more immersive and premium user interface, aligning with Google's Material You design language.

3. Enhanced Widget Customization

Widgets are now more dynamic, with better layout control, transparency settings, and resizing options. Whether you're a minimalist or a power user, One UI 7 lets you build a home screen that matches your personality and daily needs.

4. Larger Home Screen Folders

Folders on the home screen are now larger and more informative, allowing users to preview apps within folders without opening them. This small but impactful change enhances usability and aesthetics.

5. Revamped UI and System-Wide Design Changes

One UI 7 introduces subtle design changes throughout the system, including updated animations, fluid transitions, and cleaner app interfaces. Samsung’s own apps—like Phone, Messages, Gallery, and Settings—have also been refreshed to fit the new design philosophy.

Fixes multiple vulnerabilities affecting both Android OS and Samsung’s proprietary apps.
Improves system stability and app compatibility.
Enhances protection against malware and unauthorized access.

With security threats becoming more sophisticated, keeping your device up to date with the latest patches is critical—and Samsung delivers well on this front.
