Oxygen OS or One UI (2025): Which UI Is Better in Nepal?
Smartphones today are more than just powerful devices—they’re personalized hubs for communication, entertainment, productivity and more. But what truly defines a user’s daily smartphone experience? It’s not just the specs—it’s the software. In the Android world, Samsung’s One UI and OnePlus’s Oxygen OS are two of the most prominent user interfaces (UIs) that sit on top of Android. Each has its loyal following, unique design philosophy and feature set. For Nepali users in 2025—where smartphones from both brands are readily available on platforms like Daraz, Hukut, Meezmo and offline mobile shops in New Road or Pokhara—choosing between OnePlus and Samsung often boils down to the software experience(Oxygen OS or One UI). Let’s compare Oxygen OS vs Samsung One UI in detail to help you decide which one delivers the better user experience.
1. User Interface (UI) Design and Cleanliness
Oxygen OS:
- Oxygen OS is praised for its stock Android feel—clean, minimal, and fast.
- It avoids unnecessary clutter and lets you focus on the essentials.
- UI elements feel light and snappy, offering a “less is more” experience.
Samsung One UI:
- One UI is feature-rich and visually refined, designed for ease of use on big screens.
- One-handed usability is excellent, especially in Galaxy phones with tall displays.
- It includes rounded menus, well-spaced options, and a highly polished visual theme.

2. Performance and Speed
Oxygen OS:
- Known for smooth, fast performance due to its lightweight nature.
- It has fewer background processes and apps, making it more responsive.
- Great for users who want maximum performance from their hardware.
Samsung One UI:
- Historically criticized for being heavy, but now greatly optimized.
- One UI 7 (2025) includes performance profiles, improved RAM management, and reduced bloatware.
- Powerful devices like the Galaxy S25 Ultra handle One UI effortlessly.
Verdict:
Oxygen OS feels faster on mid-range phones. But with high-end hardware, One UI is just as smooth—and often more versatile.
3. Customization and Personalization
Oxygen OS:
- Offers basic customization: icon packs, accent colors, fonts, and themes.
- Has Zen Mode, custom gestures, and shelf widgets.
- However, it feels more limited compared to Samsung.
Samsung One UI:
- One UI is a customization powerhouse.
- Features like Good Lock, Theme Store, and Edge Panels allow deep changes.

Verdict:
For users who love to tweak every detail of their phone, One UI clearly wins.
4. Software Updates and Longevity
Oxygen OS:
- Offers 3 years of Android updates and 4 years of security updates (on most models).
- However, OnePlus’s merger with OPPO has led to some inconsistencies and delays.
Samsung One UI:
- Samsung now provides 4 major Android updates and 5 years of security patches, even on mid-range A-series phones.
- Timely updates are a priority, and the brand is more transparent about update schedules.
Verdict:
Samsung is more reliable for long-term software support in Nepal and globally.
5. Pre-installed Apps and Bloatware
Oxygen OS:
- Keeps it minimal with very few pre-installed apps.
- No duplicate apps—uses Google apps for essentials like messaging, calendar, and phone.
Samsung One UI:
- Comes with several Samsung apps alongside Google ones (Samsung Internet, Samsung Notes, etc.).
- Some users may consider these redundant or bloatware, though many are useful.
Verdict:
Oxygen OS wins for its clean, bloat-free setup. One UI can feel a bit crowded at first.
6. Multitasking and Productivity Tools
Oxygen OS:
- Offers split screen and floating windows, but lacks advanced multitasking tools.
- Focused more on a straightforward, clean experience than productivity.
Samsung One UI:
- Supports multi-window, pop-up view, and Samsung DeX—a desktop-like environment when connected to a monitor.

Verdict:
If productivity matters to you, One UI is a clear winner.
