✨ Top Features of One UI 7 on Galaxy A73

Samsung’s One UI 7 is more than just a visual refresh. It introduces several new features and improvements that enhance the day-to-day usability of the Galaxy A73. Here are the key highlights:

1. 🎛️ Revamped Quick Settings and Notification Panel

One of the first things you’ll notice is the redesigned Quick Settings Panel. Samsung has overhauled the layout to provide:

  • Cleaner interface

  • Easier access to frequently used toggles

  • Better one-handed usability

You can now customize toggle positions, rearrange buttons, and even select different layouts depending on how you use your phone. It’s smarter and more personalized than ever.

2. 📲 Now Bar and Live Notifications

A standout new addition in One UI 7 is the Now Bar – a persistent status area that shows:

  • Ongoing activities

  • Live app interactions

  • Background operations

For instance, when you're on a call, streaming music, or using navigation, you’ll see a dynamic bar at the bottom or top of the screen with quick actions.

Live Notifications also enhance your lock screen and home screen experience. They display real-time app information, so you can see updates from apps like Uber, Spotify, or Calendar without opening them.

3. 🛡️ Improved Privacy and Security

Security is a top priority in One UI 7. The update introduces enhanced permission controls, better notification access management, and new indicators when the camera or microphone is in use.

Combined with the May 2025 security patch, your Galaxy A73 is now more secure than ever against modern threats and vulnerabilities.

4. 🧩 Upgraded Samsung Apps

Samsung has updated many of its native apps to match the new One UI 7 design language. This includes:

  • Samsung Messages

  • My Files

  • Samsung Internet

  • Samsung Health

  • Samsung Notes

Expect better animations, simplified menus, and smoother app performance.

5. 🔋 Better Battery Optimization and Background App Management

With Android 15, Samsung brings improved battery management tools that reduce background power usage. Features like Adaptive Battery, App Hibernation, and Smart Suggestions are now more responsive and energy-efficient.

As a result, Galaxy A73 users may notice longer screen-on time and better overall battery health.

🔁 When Will Galaxy A53 and A33 Get One UI 7?

Following the successful rollout for the Galaxy A73, Samsung is preparing to release the update for the Galaxy A53 and A33 models. These devices share similar hardware configurations, so they are expected to receive the update within the next few weeks.

Samsung is likely to push One UI 7 for the A53 and A33 with region-specific builds, so the rollout may vary by market.

📝 May 2025 Security Patch Details

With the May 2025 security update, Samsung fixes multiple critical and high-severity vulnerabilities in the Android operating system. This includes patches for:

  • Remote code execution threats

  • Kernel-level security flaws

  • Memory leaks

  • Privacy bugs affecting third-party apps

This update further solidifies Samsung's commitment to user data protection and device longevity.

📷 What’s Missing in the One UI 7 Update?

While the update is feature-packed, some flagship features from the Galaxy S24 series such as AI Live Translate, Circle to Search, and AI Photo Editing are not included in the Galaxy A73 update due to hardware limitations.

However, the inclusion of Live Notifications and the Now Bar gives the A73 a near-flagship feel, making it a worthy upgrade for 2025.

💡 Final Thoughts

The Android 15-based One UI 7 update for the Galaxy A73 is a significant upgrade that transforms the way users interact with their smartphones. With a modern interface, real-time notification features, improved customization, and stronger privacy controls, the update truly elevates the mid-range Galaxy experience.

Samsung has once again proven that even non-flagship phones in its lineup receive top-tier software treatment. If you're a Galaxy A73 owner, this is the perfect time to update your device and unlock the full potential of One UI 7.
