Critical Clarification: The Divergence Between the Global and Chinese Models ?

It is essential for any analysis of this device to clearly distinguish from the outset: the OPPO Reno 12 Pro marketed in global markets (Europe, Latin America, etc.) under the model code CPH2629 is substantially different from the version launched in China (PJW110). This report focuses exclusively on the Global model, which is what most users outside China will encounter.

The differences are significant and directly impact the phone's core performance and functionality. The Chinese model is equipped with a high-end processor, the MediaTek Dimensity 9200+, and a larger main camera sensor (Sony IMX890, 1/1.56"). In contrast, the global model opts for a mid-range chipset, the MediaTek Dimensity 7300-Energy, and a smaller main sensor (1/1.95"). This apparent "downgrade" in specifications is not an oversight but a strategic market segmentation decision by OPPO. For the highly competitive domestic Chinese market, raw power is a primary selling point. However, for international markets, OPPO has chosen a configuration that, while sacrificing raw performance, introduces a highly demanded feature absent in the Chinese version: the ability to expand storage via a microSDXC card. This strategy allows OPPO to lower the price in the global market and offer flexibility that some users value over processing power. Nonetheless, this divergence creates a dissonance for informed consumers, who may perceive the global model as an inferior version?a recurring criticism in specialized analyses.

Chassis and Resistance: Aesthetics vs. Durability ??

The construction of the Reno 12 Pro is a story of contrasts. On the one hand, the front is protected by Corning Gorilla Glass Victus 2, one of the most durable glasses on the market, and the back is glass, giving it a premium look. However, this high-end perception is undermined by the choice of a plastic frame. While this material helps keep the device's weight at a light 180 grams, many reviews agree that it feels "cheap" to the touch and doesn't match the price range. This design choice seems to be a cost-saving measure, where OPPO has invested in screen appearance and protection but cut back on chassis structure.

In terms of resistance, the phone has an IP65 certification, which fully protects it against dust ingress and low-pressure water jets from any direction. This means it will survive rain or accidental splashes but is not designed for immersion. OPPO reinforces this feature with internal durability tests, such as pressure and drop resistance, but for the user, the main guarantee of durability remains the Victus 2 glass on the screen.

"Infinite View Screen": The Crown Jewel ?

Without a doubt, the screen is the standout component of the Reno 12 Pro. It is a 6.7-inch Flexible AMOLED panel with a distinctive design feature: it is curved on all four sides. This creates an immersive feeling and a very attractive "floating screen" look. With a FHD+ (2412 x 1080) resolution, a refresh rate of up to 120Hz, and compatibility with HDR10+, the visual quality is excellent. The maximum brightness of 1200 nits ensures perfect visibility even under direct sunlight.

Despite its strengths, the screen is not without criticism. Some technical reviews point out that the default color modes tend to excessive saturation, which may not appeal to image purists. Additionally, there have been reports of inconsistent behavior from the ambient light sensor, causing the automatic brightness adjustment to not always work smoothly and accurately.

Processing Unit and Performance: The Achilles Heel ?

Performance is the most controversial aspect of the Reno 12 Pro. It is powered by the MediaTek Dimensity 7300-Energy chipset, a variant of the Dimensity 7300 optimized in collaboration with OPPO to improve energy efficiency. This 4 nm SoC features an eight-core CPU (four performance Cortex-A78 at 2.5 GHz and four efficiency Cortex-A55 at 2.0 GHz) and a Mali-G615 GPU.

While for everyday tasks like browsing social media, video playback, and light multitasking the performance is smooth, the device shows its limitations in more demanding scenarios. In synthetic performance tests, it consistently lags behind direct competitors in the same price segment.

Performance Comparison (Benchmarks) ?

The objective data from the benchmarks confirm analysts' subjective perceptions: the Reno 12 Pro is not the most powerful phone in its category. This lack of power not only affects the most demanding games but also the processing of AI functions like "AI Eraser," which can be slow. This raises a concern about the device's long-term value. Although OPPO promises three major Android updates, the hardware may struggle to optimally run future versions of the operating system, potentially leading to performance degradation over time and diminishing its appeal to users seeking a durable phone.

"AI Portrait Expert" Camera System: Hits and Misses ?

OPPO markets the Reno 12 Pro as an "AI Portrait Expert," and its camera system is designed to back up this claim. The triple rear module comprises:

• Main Camera: A 50 MP sensor with an f/1.8 aperture and optical image stabilization (OIS), delivering good results in well-lit conditions.
• Telephoto Camera: A 50 MP sensor with a 47mm focal length (equivalent to a 2x optical zoom), ideal for portraits by compressing space and offering a more natural focus.
• Ultra-Wide Camera: A modest 8 MP sensor with an f/2.2 aperture.

The image quality of the main and telephoto cameras is solid, producing sharp photos with good dynamic range, although some reviews criticize excessive facial detail smoothing. The real weak point is the ultra-wide camera. Its 8 MP sensor has been described as "disappointing" and "outdated," offering inconsistent quality, less detail, and poor performance in low-light conditions.

The 50 MP front camera with autofocus (AF) is one of the device's strengths, capable of capturing high-quality selfies with great detail. As for video, both the rear and front cameras can record in 4K at 30fps, but image stabilization (a combination of EIS and OIS) has been shown to be deficient, especially when recording while walking.

Battery and Charging: An Undisputed Strong Point ??

If there is one area where the Reno 12 Pro shines without reservations, it is in battery life. Equipped with a large 5000 mAh battery, the phone offers excellent duration, exceeding 14 hours of continuous active use in rigorous tests. In daily use, this translates to the ability to last more than a full day on a single charge, even with heavy use.

The 80W SUPERVOOC fast charging technology is equally impressive, capable of charging the battery from 0 to 100% in approximately 46 minutes. It is worth noting that, although the phone is compatible with the Power Delivery (PD) standard, charging will be significantly slower (at 13.5W) if a non-SuperVOOC compatible charger is used. Ironically, in most European and global markets, the 80W charger is not included in the box, so users must purchase it separately to take advantage of one of the phone's standout features.

Preventive Maintenance and Essential Care ??

To ensure the longevity and optimal performance of the OPPO Reno 12 Pro, adopting a series of preventive maintenance practices is crucial.

Physical Protection and Longevity ??

Since the device's frame is plastic, using a protective case is highly recommended to protect it from drops and bumps. While some regional variants may include a case in the box, this is not a universal practice, so purchasing one separately is a wise investment. For cleaning, a soft microfiber cloth should be used for the screen and body, avoiding abrasive liquids. Despite its IP65 certification, prolonged exposure to liquids should be avoided, and the device should never be submerged.

Battery Optimization (Software and Habits) ?

ColorOS offers several tools to manage battery health. It is recommended to enable the Power Saving Mode when the charge level is low and use the Smart Charging function, which learns the user's charging patterns to avoid keeping the battery at 100% for extended periods, such as overnight. OPPO promises that the battery will retain more than 80% of its original capacity after 1000 charge cycles (approximately 4 years of daily use), a testament to the quality of its components and management software.

Operating System Maintenance ??

Keeping the ColorOS 14.1 operating system and applications updated is vital to receive security patches, bug fixes, and performance improvements. One of the most valuable and little-known features of ColorOS is the "Repair Mode." This tool creates a secure partition with a clean Android system, allowing a technician to perform diagnostics and repairs without accessing the user's personal data (photos, messages, accounts). This privacy feature is a great asset when taking the phone to a service center.

To activate Repair Mode:

1. Go to Settings > System and Updates > Repair Mode.
2. Tap Enter Repair Mode and follow the instructions.
3. The phone will reboot into a secure environment.

To exit Repair Mode:

1. From repair mode, go to Settings > System and Updates > Repair Mode.
2. Tap Exit Repair Mode and enter the security PIN.
3. The device will reboot back to normal with all data intact.

Common Issues and Critiques Diagnosis ?

Despite its strengths, the OPPO Reno 12 Pro is not without issues and critiques from both analysts and the user community.

Performance and Software Issues ?

• Slowness and Lag: The most common complaint is overall performance not living up to its price. Users report lag in games and slowness when processing heavy tasks, such as video editing or using AI features.
• ColorOS Bugs: Following some software updates (especially to beta or initial versions of ColorOS 15), users have reported issues like abnormal battery drain, intermittent Bluetooth connection loss, poor network signal reception, and external speaker failures.
• Bloatware: The operating system comes with a considerable amount of pre-installed apps and games that not all users want, known as bloatware.
• Disappointing AI Features: Tools like "AI Eraser 2.0," though marketed as revolutionary, often fall short of expectations. In practice, they can leave noticeable visual artifacts when removing objects from photos, functioning more as a marketing gimmick than a professional editing tool.

Hardware Deficiencies and Limitations ?

• Ultra-Wide Camera: As mentioned earlier, the quality of this 8 MP sensor is a consistent weak point, with poor detail and color consistency compared to the main camera.
• Video Stabilization: Video stabilization is mediocre, especially when recording in motion. The "Ultra Steady" mode improves the situation but is limited to a 1080p resolution.
• Ambient Light Sensor: The erratic behavior of the automatic brightness sensor is a recurring complaint, forcing users to manually adjust brightness more often than desired.
• Screen Fragility and Repair: Despite featuring Gorilla Glass Victus 2, screens can still break. An additional problem is the difficulty some users have encountered in finding independent repair shops with replacement parts in stock, which may force them to rely on official service centers, often more expensive.

Repair Manual and Component Replacement ??

This section is aimed at technically knowledgeable users who wish to carry out common repairs. Proceeding with self-repair will void the warranty and carries the risk of damaging the device.

Preparation, Tools, and Universal Precautions ?

Before starting any repair, having the right tools and following basic safety rules is crucial.

• Essential Tools: A precision screwdriver kit (with Phillips bits), plastic opening picks, a suction cup, a heat gun or hairdryer, and anti-static tweezers.
• Golden Precautions:
  1. Disconnect the battery first: Before handling any other internal component, always disconnect the battery to avoid short circuits.
  2. Organization: Use a magnetic mat or diagram to organize screws, which are often of different sizes.
  3. Don't force: If a component doesn't give, there is likely a hidden screw or clip. Forcing parts usually results in breakage.
  4. Be careful with flex cables: They are extremely delicate. To disconnect them, lift the small tab on the ZIF connector with a plastic tool before sliding the cable out.

Storage Expansion (Physical and Virtual) ?

The Reno 12 Pro offers two ways to expand memory, serving very different purposes.

microSD Card (Physical Storage) ?

The global model (CPH2629) features a slot for microSDXC cards, allowing for easy and cost-effective storage expansion.

1. Turn off the phone.
2. Locate the SIM tray on the bottom edge of the device.
3. Insert the SIM eject tool into the hole to remove the tray.
4. The tray is hybrid. You can opt to use two Nano-SIM cards or one Nano-SIM and one microSD card. All three cannot be used simultaneously.
5. Place the microSD card in the designated slot, ensuring it fits properly.
6. Reinsert the tray into the phone. The operating system will automatically detect the card.

RAM Expansion (Virtual Storage) ?

ColorOS includes a feature called "RAM Expansion" that allows converting part of the internal storage (ROM) into virtual RAM.

1. Go to Settings > About Device > RAM.
2. Enable the "RAM Expansion" option and select the desired amount (up to an additional 12 GB).
3. A restart will be required to apply the changes.

It is important to understand that this virtual RAM is significantly slower than physical RAM. On a phone that already has 12 GB of LPDDR4X RAM, the real benefit of this feature is questionable and, according to some users, might even slow down the system instead of improving it.

Screen Replacement (Repair #1 - The Most Common and Expensive) ??

A broken screen is one of the most frequent repairs. The key to success lies in choosing the right replacement and proceeding carefully.

Screen Replacement Quality and Cost Comparison ?

Basic Replacement Guide ?

1. Disassembly: Turn off the phone. Apply moderate and even heat to the edges of the back cover to soften the adhesive. Use a suction cup and plastic picks to cut through the adhesive and carefully remove the cover, watching for possible connected flex cables.
2. Access: Once the cover is removed, disconnect the battery connector. Remove the screws holding the shield on the motherboard and disconnect the flex cables from the damaged screen.
3. Removal: Other components such as the motherboard or speaker may need to be removed to fully extract the screen assembly from the frame.
4. Crucial Test: Before gluing the new screen, temporarily connect it to the motherboard. Turn on the phone and verify that both the image and touch function work perfectly. This step avoids having to disassemble an already glued screen if it turns out to be defective.
5. Installation: Thoroughly clean the frame of any old adhesive residue. Apply the new adhesive (usually included with the replacement) and mount the new screen. Reconnect all components, starting with the battery last, and seal the back cover.

Battery Replacement (Repair #2 - Longevity Maintenance) ?

Over time, all batteries degrade. Replacing it can restore the phone's original autonomy.

• Symptoms of a defective battery: Drains quickly, shuts off at 20-30% charge, overheats, or takes too long to charge.
• Identifying the Part: The battery model for the Reno 12 Pro is the BLPA57, with a capacity of 5000 mAh. Original and compatible replacements can be found in specialized stores.
• Replacement Guide:
  1. Follow the same back cover disassembly steps described for screen replacement.
  2. Disconnect the battery connector from the motherboard.
  3. The original battery is secured to the chassis with strong adhesive. Carefully use a flat plastic tool to pry it out or apply a few drops of isopropyl alcohol to soften the glue.
  4. Place the new battery, which often includes its own adhesive.
  5. Reconnect the battery to the motherboard and reassemble the phone.

Other Viable Repairs ??

The modular design of the Reno 12 Pro allows for relatively easy replacement of other components, such as the glass back cover, the USB-C charging port module, and the camera glass lenses. The disassembly process is similar to what has already been described.
