vivo X300 Ultra Review (English): A Surprisingly Powerful Camera Upgrade, Better Screen & Speakers—But the Biggest Question Is: Is It Finally Enough?

The Vivo X300 Ultra arrives with a promise that feels very 2026: go absurdly hard on the camera, then polish the rest just enough to call it “Ultra.” In Vietnamese reviewer slang, it’s a “camera siêu DÀY” kind of phone—thick, bold, and unashamed about prioritizing imaging. After spending time with it in a review mindset, the headline practically writes itself: the screen and speakers are better, but still not quite enough to dominate every rival. That said, if your buying decision is driven by photography and video first, the X300 Ultra has a persuasive case, even before you hit record on your first night shot.

Design-wise, the X300 Ultra makes a statement the moment it lands on the table. The camera module is large and heavy-looking, and the balance in hand reflects that. Some people will call it chunky; others will call it purposeful. The build feels premium with tight seams and a confident frame, but you should expect a bit of wobble when tapping on a desk unless you use a case. Button placement is sensible, haptics are crisp, and the overall fit-and-finish screams flagship. Still, this is not the phone you buy to chase thin-and-light minimalism—it is a tool built around optics and sensors.

Where Vivo claims improvement beyond the camera is the display, and yes, it is better. Colors look richer, peak brightness is more usable outdoors, and the panel tuning feels closer to what you’d expect from a top-tier flagship. Scrolling is smooth, touch response is reliable, and HDR content pops with satisfying contrast. But “better” doesn’t automatically mean “best.” Depending on what you compare it to, you may notice that rivals can push higher brightness more consistently, or handle reflections a bit more gracefully. It’s a very good screen, just not the unquestioned champion in every situation.

Then there are the speakers—another area Vivo has clearly worked on. The stereo separation feels wider, vocals stay clear at moderate volume, and the bass presence is improved enough to notice in games and YouTube viewing. For casual media consumption, the X300 Ultra is genuinely enjoyable. Yet the “chưa ĐỦ” part still applies: at maximum volume, some tracks can lose composure, and the overall fullness may not match the absolute best audio flagships. It’s a step forward, but if you are picky about speaker depth and distortion control, you may still rank other phones a touch higher.

Now to the reason this phone exists: the camera. The X300 Ultra’s imaging pipeline is aggressive in a good way—detail is sharp without looking over-processed, dynamic range is strong, and low-light performance is one of its standout traits. Portraits can look striking, with subject separation that feels confident and skin tones that can be tuned toward natural rather than plastic. The “thick camera” hardware translates into practical results, especially when zooming or shooting challenging scenes like backlit streets, indoor restaurants, or nighttime cityscapes. Video is also a strong point, with stabilization that inspires confidence when walking and panning.

Performance and daily use are what make or break camera-centric flagships, and the X300 Ultra largely keeps up. Apps open quickly, multitasking is smooth, and thermal behavior is reasonable for extended shooting sessions—though long video recording will still warm the phone, as expected. Battery life feels tuned for real-world use: you can comfortably get through a day with mixed camera time, social apps, and streaming. Charging is fast enough to reduce anxiety, and the software experience is modern and feature-packed, though some users may prefer a cleaner interface. In short: the X300 Ultra is a camera monster with better display and sound, but not the final word in those categories.
