Galaxy S26 Ultra vs OnePlus 15 vs Vivo X300 Pro: Detailed Specifications Comparison
Galaxy S26 Ultra vs OnePlus 15 vs Vivo X300 Pro is one of the most debated flagship comparisons of 2026. With each brand focusing on a different strength, choosing the right premium smartphone depends entirely on what matters most to you.
Display and Design
The Galaxy S26 Ultra features a 6.9-inch Dynamic AMOLED 2X display with QHD+ resolution and a 120Hz refresh rate. It is designed for users who prefer sharp visuals and a large immersive screen.

The OnePlus 15 comes with a slightly smaller 6.78-inch AMOLED panel but pushes the refresh rate to 165Hz, making it particularly appealing for gamers and users who prioritize fluid scrolling.

Performance and Processor
Samsung and OnePlus both use the Snapdragon 8 Elite Gen 5 chipset, with Samsung offering a customized version tuned for its ecosystem. The Vivo X300 Pro runs on the MediaTek Dimensity 9500 processor, delivering competitive flagship-level performance.

Stable OxygenOS 16.0.3 Update Brings Major Visual Changes to OnePlus 10 Pro, But Key Features Are Missing

Stable OxygenOS 16.0.3 has officially started rolling out for the OnePlus 10 Pro, marking one of the biggest software upgrades the device has received so far. Based on Android 16, the update arrives with a build version of 16.0.350, a January 2026 security patch, and a substantial download size of approximately 3.57GB. While the update introduces several visual and usability improvements, it also leaves out some highly anticipated features.
Stable OxygenOS 16.0.3 focuses heavily on visual refinement and UI consistency rather than introducing entirely new system features.
Stable OxygenOS 16.0.3 Brings UI Redesign and Smoother Animations
One of the first noticeable changes after installing OxygenOS 16.0.3 on the OnePlus 10 Pro is the refined animation system. App transitions, gesture navigation, and UI interactions feel smoother and more fluid than before. The update also introduces a frosted glass design language that appears across the control center, notification panel, lock screen shortcuts, keyboard, and even system apps, such as Calculator.

The Control Center has received a significant redesign, featuring colorful tiles, transparency effects, and improved customization. Users can now resize tiles, remove sliders like brightness or volume, and reset the layout anytime. Notifications can be switched between classic and split layouts, offering more flexibility based on personal preference.
New Customization Options and Flux Themes
OxygenOS 16 adds a dedicated “Home Screen, Lock Screen & Styles” section, bringing Flux themes to the OnePlus 10 Pro. These include live clock designs, aerial views, and animated wallpapers. Users can resize lock screen clocks, apply depth effects, blur wallpapers, and even add custom text powered by AI-based wallpaper analysis.
A new Flux icon pack is also included, allowing app icons to adapt dynamically to system or wallpaper colors. Additionally, OnePlus has introduced a new “One Serif” font with adjustable size and width options.

AI Features and Missing Additions
Several AI-powered tools make their way to the device, including AI Writer, AI Translate, Recorder summaries, live transcription, and background noise removal. Live Alerts now support multiple apps running simultaneously, such as timers, recordings, and music playback.
However, not all flagship features have arrived. The OnePlus 10 Pro does not receive the new charging animation, full-screen Always-On Display, AI Search in settings, Mind Space, or AI-powered gallery editing tools. These omissions may disappoint users expecting feature parity with newer OnePlus devices.

Final Verdict
OxygenOS 16.0.3 delivers a visually polished and smoother experience on the OnePlus 10 Pro, but the absence of several premium AI and system features makes the update feel slightly incomplete. While performance and design upgrades are welcome, it remains uncertain whether missing features will arrive in future updates.
With Stable OxygenOS 16.0.3, OnePlus delivers a smoother experience, but feature limitations prevent it from feeling like a complete flagship upgrade.
