Design and Build

The Oppo F X9 Pro features a significant design overhaul compared to its predecessor, the Oppo F X8 Pro. While the F X8 Pro had a more traditional curved design reminiscent of older Chinese smartphones, the F X9 Pro adopts a flat, squared-off aesthetic similar to current flagship offerings from Apple, Samsung, and Vivo. This results in a more modern and premium feel. The bezels around the screen are also thinner than on the F X8 Pro, which was noted as a drawback of the previous model.

The reviewed unit is in a "titan" color, described as a light brown, which the reviewer finds striking. A white variant is also mentioned as being brighter. The F X9 Pro feels slightly heavier and thicker than the F X8 Pro, attributed to the upgraded camera components. The camera module itself is now more squared, a design choice the reviewer personally dislikes, preferring the rounder design of the F X8 Pro. However, it's acknowledged that this is subjective, and some users may prefer the more unified, squared look. Overall, the build quality and general design are considered excellent, with the camera module's aesthetics being the primary point of contention.

Display

The Oppo F X9 Pro is equipped with a 6.78-inch display, which is described as large but not excessively so, comparable to non-Pro Max iPhones. It offers a high resolution and good brightness, with a typical brightness of 800 nits and a peak brightness of 1800 nits. The refresh rate is adaptive, capable of reaching up to 120 Hz. The display is deemed excellent for a flagship device in 2025, providing good contrast, color reproduction, and brightness, meeting user expectations without any surprises.

Camera System and Photography

The camera is a major focus for the Oppo F X9 Pro, with significant upgrades. Both the main and ultra-wide cameras boast 50MP sensors. The most notable improvement is the telephoto lens, which has been upgraded to a 200MP sensor. While a 200MP shooting mode is available, the phone primarily uses AI algorithms to combine data from multiple pixels for enhanced image quality, especially in low-light conditions, resulting in better noise reduction.

Photography Performance:

• Color Science: In good lighting, colors are pleasing. Oppo's signature is a slightly warmer, more "eye-pleasing" tone, which may not always be true to reality. For instance, skin tones can appear warmer than in person, but this is often preferred by many viewers. This approach of enhancing colors for aesthetic appeal is a common trait of Chinese smartphone brands.
• Zoom Capabilities: The optical zoom is 3X. Beyond 3X, the phone utilizes digital zoom, combining sensor cropping with AI algorithms. While this can produce usable images for social media, it cannot match the quality of true optical zoom.
• AI Processing: AI plays a significant role, particularly in filling in details in areas like signs or license plates, which can sometimes lead to inaccuracies. However, for general use and social media sharing, the results are acceptable.
• Low-Light Performance: The 200MP sensor, through AI processing, offers improved noise reduction in low-light scenarios.
• Comparison to F X8 Pro: The AI processing in the F X9 Pro is noted to be less aggressive in smoothing skin tones compared to the F X8 Pro, retaining more natural detail.
• Wide and Ultra-Wide: The 0.5X (ultra-wide) and 1X (main) camera performance is considered good.
• Overall Experience: The camera system provides an enjoyable and inspiring experience, encouraging more frequent photography.

Videography

Oppo has invested in improving video recording capabilities for the F X9 Pro. Compared to the F X8 Pro, which suffered from washed-out and overly bright footage, the F X9 Pro offers significantly improved video quality. While extreme zoom levels in video will still exhibit some degradation due to digital processing, the ability to achieve a usable zoomed-in shot is often sufficient. Oppo aims to compete with or surpass iPhone's video capabilities.

Hopplus Teleconverter Kit

This optional accessory provides an external telephoto lens that attaches via a carbon-fiber-like case. It's particularly useful for shooting from a distance, such as at concerts or when capturing distant subjects in landscapes where the phone's native telephoto lens might struggle.

• Components: The kit includes a lightweight case and the teleconverter lens.
• Usage: The case is mandatory for attaching the lens. A special teleconverter mode on the phone is required for optimal image quality, which also engages specific Oppo algorithms.
• Limitations: When the teleconverter is attached, other cameras are inaccessible, requiring removal of the accessory to switch to wide or ultra-wide lenses. The process of attaching and detaching is quick.
• Comparison to Vivo X300 Pro: The kit lacks a built-in grip, unlike the Vivo X300 Pro.

Grip Accessory (Magnetic Bluetooth Grip)

This accessory, which needs to be purchased separately (not officially sold in Vietnam at the time of the review), enhances the handling and shooting experience.

• Attachment: It uses a magnetic mount that attaches to the case, similar to MagSafe.
• Connectivity: It connects to the phone via Bluetooth, requiring the grip to be powered on.
• Features:
  • Ergonomics: Significantly improves grip comfort, making it more akin to a dedicated camera.
  • Controls: Includes a joystick for rotation, a shutter button with half-press for focus and full-press for capture, and a double-press to launch the camera.
  • EV Dial: A dial for adjusting exposure value (EV).
• Versatility: The magnetic mount allows for easy rotation, enabling both horizontal and vertical shooting with the grip attached, a feature not found on the Vivo X300 Pro.
• Recommendation: The reviewer strongly recommends Oppo make this accessory officially available in Vietnam due to its utility.

Concert Photography and Videography

The Oppo F X9 Pro, especially with the teleconverter and grip accessories, is highlighted as a strong performer for concert photography and videography.

• Challenging Conditions: Concerts present difficulties with fast-moving subjects, complex and changing lighting, and often require shooting from a distance.
• Performance: The F X9 Pro, even from far distances (e.g., the back of a stadium), produces good image and video quality with acceptable colors and contrast.
• AI Intervention: While AI is used for facial details, it's less aggressive than on the Vivo X300 Pro, resulting in better retention of skin texture.
• Motion Blur: Some motion blur is expected and normal due to the fast movement of performers and the limitations of phone cameras in such dynamic environments.
• "Stage Mode": Both Oppo and Vivo phones offer a "Stage Mode" which can improve capture speed by slightly darkening the image and increasing contrast, making performers stand out. This mode is recommended for concert shooting.
• Post-Processing: The phone applies additional algorithms after capture, often darkening the background and enhancing the subject's contrast, leading to aesthetically pleasing results.
• User Experience: The ability to capture and share these memories is a valid and enjoyable aspect of attending concerts, a need the F X9 Pro effectively addresses.

Front Camera

The front camera is considered good, with no significant complaints. A key improvement is the addition of autofocus, which greatly enhances selfie and vlogging quality compared to the F X8 Pro, which lacked this feature.

Color OS 16

The Oppo F X9 Pro runs on Color OS 16, an upgrade from Color OS 15. This version is noted for its even smoother animations and transitions, contributing to a fluid user experience, especially when combined with the 120Hz display.

• Interface: The interface is familiar and shares similarities with iOS, making it easy for users who switch between Android and iPhones.
• AI Features: Existing AI features like text summarization, note-taking enhancements, and voice-to-text are retained and function well.
• Cross-Device Integration: Features like wireless photo sharing with iOS and interaction with Mac devices are mentioned as existing functionalities.
• Limitations: At the time of the review, Color OS 16 on the international version of the F X9 Pro does not support AirPods and Apple Watch connectivity, a feature Oppo has mentioned but not yet implemented globally. The reviewer expresses curiosity about how this integration will work and potential legal implications.

Performance and Hardware

The Oppo F X9 Pro is powered by the MediaTek Dimensity 9500 chipset and comes with 16GB of RAM. This configuration is deemed sufficient for everyday use and general tasks. The reviewer, who primarily plays Call of Duty Mobile, finds the performance adequate, noting that even older phones can handle such games. The reviewer is unsure about the performance with newer, more demanding games and encourages user feedback.

Battery Life

The Oppo F X9 Pro features a 7500 mAh silicon carbon battery, one of the largest capacities available in flagship phones for 2025.

• Longevity: The battery life is exceptional. During a 6+ hour concert, with 5G enabled, email checking, and social media posting, the phone still had 30-40% battery remaining.
• Typical Usage: For regular use, the battery can last approximately 1.5 days, requiring charging on the second day.
• Key Advantage: Battery life is presented as a significant advantage, allowing users to use the phone without constant worry.

Drawbacks and Conclusion

Drawbacks:

• Camera Module Design: The reviewer's personal dislike for the squared camera module.
• Weight: The phone is slightly heavier than the previous generation, a trade-off for the advanced camera system.

Conclusion:

The Oppo F X9 Pro is described as a "very interesting" and "fun" device, particularly for photography and videography enthusiasts. The reviewer plans to use it for future concert events. The phone offers a compelling package with its upgraded camera system, impressive battery life, and refined software. The key areas of improvement over the F X8 Pro are the camera hardware and video recording capabilities. The optional accessories, especially the teleconverter and the magnetic grip, significantly enhance the user experience, transforming the phone into a more capable imaging tool. The reviewer emphasizes that while the phone is not light, this is a common characteristic of high-end camera phones, and users seeking a lighter option might consider the standard F X9 model. The reviewer also notes the discovery of a similar grip accessory on Shopee, though its full compatibility with the Oppo F X9 Pro is unconfirmed.
