OPPO R11 Review: With Dual Cameras

[PConline Review] Just as there are a thousand Hamlets in the eyes of a thousand people, the portrait of the OPPO cell phone is undergoing a butterfly change among different users. In 2016, the number of OPPO patent applications accepted reached 3,778, ranking fifth among domestic companies. At the same time, R9 sold more than 20 million units as the best-selling mobile phone, and R9s ranked first in sales for five consecutive months since listing.

From the fire to the north and south of the "charging 5 minutes, call 2 hours" to "before and after 20 million, more clear pictures," OPPO R11 debut. Even Jay Chou has become a new member of the OPPO star family. Who else in the world does not know?

Before starting the evaluation, we may wish to briefly understand the OPPO R11 through a video.

Hardware Configuration

In terms of configuration, OPPO R11 first launched the Snapdragon 660. The performance of the chip is close to the previous generation flagship chip Snapdragon 820, and the adoption of 14nm technology, power performance is also worth the wait. The screen is 5.5 inches 1080P and the memory is 4+64GB. The camera is the biggest selling point of the aircraft, the main camera is 20 million +16 million pixels dual camera, supports 2x zoom and portrait mode. The front is 20 million pixels.

The network standard supports full Netcom dual card dual standby, battery capacity of 3000mAh, supports consistent VOOC flash charge. Provides three colors of gold, rose gold, and black, running ColorOS 3.1 based on Android 7.1.1.

Appearance: meticulous workmanship, comfortable feel

In addition to performance and photographing, the OPPO R11's design has also been updated with great intensity. OPPO R11's exterior design mainly revolves around fashionable, lightweight elements, pre-fingerprint recognition and mainstream integrated metal fuselage. OPPO R11 feels very detailed and feels good.

OPPO R11 uses metal curved body design, the entire back is not a flat. In the hand, the continuous curved back cover fits the palm well, making it very comfortable to hold. In addition, OPPO R11 body weight is only 150g, while the thickness of only 6.8mm, very thin. It is no exaggeration to say that thanks to the sleek, lightweight design of the body, the OPPO R11 is the 5.5-inch cell phone we currently come across.

Thanks to the metal-curved body design, the OPPO R11's frame is thinner than the overall thickness, so it has an ultra-thin waist, which makes it more visually slim. It is worth mentioning that the frame of the OPPO R11 also uses a continuous arc design, which can further enhance the sense of the mobile phone. It is reported that in order to find the most comfortable curvature of this narrow edge, OPPO R11 was adjusted for a year and a half.

The main opening of the OPPO R11 body is concentrated on the bottom of the fuselage, the same design as the previous generation models. Unfortunately, the OPPO R11 did not use the mainstream Type-C, which may be in order to be compatible with its own VOOC lightning.

There is also a detail that deserves attention. The OPPO R11 upgraded the microslit antenna on the R9s to a microstrip antenna 2.0, which turns the original three microstrip antennas into two, and turns the line into a curve extending along the upper and lower edges. This design makes the OPPO R11 look very sophisticated, further increase the proportion of the metal body, so that the body back cover is more integrated.

The front of the fuselage, OPPO R11 continues the R9s design style, using pre-fingerprint keys (can not be pressed, there are two hidden virtual keys on both sides), the screen panel looks very simple. As for the screen, the frame of OPPO R11 is narrow to 1.6mm, which brings a good visual experience. If you have the opportunity, you can touch the real machine, OPPO R11's feel and workmanship is indeed very good.

Photographing: 2x zoom, beautiful portrait

The OPPO R11 raises the front camera to 20 million pixels with F/2.0 aperture and 5P mirror sets. The rear camera adopts a dual-camera solution with 16 million pixels wide angle and 20 million pixels telephoto. Among them, the wide-angle lens is equipped with F / 1.7 aperture, 6P lens group, telephoto lens with F / 2.6 aperture, 5P mirror group, can achieve 2 Ã— double-camera zoom.

In addition, the Snapdragon 660 supports the Spectra 160 ISP, has a 6-layer noise reduction algorithm, better focused pixel point compensation technology, and uses the high-performance and low-power HVX vector expansion technology for the first time, further improving processing capabilities.

Of course, this time on the R11, the most popular concern is the portrait shooting experience. In addition to having excellent camera hardware, OPPO attaches great importance to the optimization of the software above. Let's take a look at the portrait part below.

Portrait shooting

The R11 rear camera has a depth-optimized portrait mode that allows one-touch â€œbeauty + smart exposure + background blur + skin tone adjustmentâ€ effects. On the other hand, the front camera was also upgraded to background blur 2.0, and the software HDR was added, and the beauty algorithm was optimized.

OPPO R11 supports face tracking technology. The camera software performs software algorithm compensation and focus prediction based on the real-time data of the gyro jitter to prevent blurring caused by camera shake. Then through the advanced face tracking technology to ensure the clarity of the image.

The slave graph can be seen that the recognition rate of tracking focus is relatively high and the tracking speed is fast. Let's take a look at the selfie part below.

Virtualization; Virtualization

The front camera of OPPO R11 also supports the blur function. Compared with R9s, it is upgraded to the front background blur 2.0. It can deeply learn the silhouette information of the characters and shoot self-timer with the effect of the spot depth of the depth of field. It looks more real. However, comparing the above figure with the figure below, you can know that there is a certain distance from the background, and the background should not be a pure color as far as possible.

Front background blur off; front background blur open

Many people think that self-timer backlighting, or dark face, or white background, these are not the effect the user wants, so OPPO R11 front-end automatic HDR function, when the backlight self-timer The picture will not be overexposed and the performance will be clearer.

Front Automatic HDR Off; Front Automatic HDR On

At present, many dual-camera phones are focused on portrait mode, and OPPO R11 also has this popular feature, and has its own characteristics in the optimization above.

OPPO R11 has learning algorithms that are trained in hundreds of thousands of samples. The effect is more natural and realistic. It also has an intelligent exposure function that can intelligently identify more than 50 scenes and automatically adjust the exposure of portraits and backgrounds.

In addition, intelligent skin tone adjustment is also a key to good portraits. OPPO R11 uses 3D face recognition technology to recognize portraits. The skin color appears more natural and beautiful. The beauty algorithm is further optimized and the dermabrasion is more uniform.

From the portrait proofs, we can see that OPPO R11 does have certain advantages in optimization. For example, in the blurring of characters' edges, especially the position of the hair, the processing is more natural, and the color and brightness of the characters are just right. In place, it is very easy to take photos that sister likes in automatic mode.

2x dual camera zoom experience

At the MWC 2017 show at the beginning of the year, OPPO launched a periscope dual-camera technology that supports 5x lossless zoom. It is very forward-looking. As the first mass-produced dual-camera OPPO phone, the R11 uses a more sophisticated and practical 2x dual-camera zoom. The wide-angle lens captures landscape subjects, telephoto lenses capture sketches, portraits, and takes into account the dual needs of zoom and background blur.

So, in essence, these are two fixed-focus lenses, and achieving relatively lossless zoom is its first benefit. For mobile phones, the need to shoot a distant view is still very common. The OPPO R11 is able to create a space-compression feel and retains good image quality in zoom mode.

When using the wide-angle lens alone, the OPPO R11 continues the stable and reliable performance of the R9s. White balance, accurate color reproduction, excellent nighttime noise control, and a neat, focused focus, give users confidence in their use.

As can be seen from the 100% enlarged image, the performance of the screen is still relatively clear, leaving more details.

General Sample Reviews

When the two shots work together, the double shot shows a second benefit - background blurring. The focal length covered by the OPPO R11 is particularly suitable for shooting portraits, foods, flowers and plants. The edge of the subject is detailed and the blur effect is natural.

The front camera is comparable to self-timer upgrade from 16 million pixels to 20 million pixels, and the front-end background blur 2.0 function is added. Through the automatic HDR smart adjustment background exposure, with the beauty skin beauty algorithm, you can take a clear, whitening moment. Yourself.

Restaurants with poor ambient lighting have put pressure on the main camera of many mobile phones. The OPPO R11 is still able to shoot pleasing portraits, girls naturally love to put it down.

The low light performance of the rear camera is also satisfactory. The purity of the screen is relatively high, and it is difficult to detect noise under normal conditions.

More proofs

In general, OPPO did a good job in R11's photography. Whether it was a front or rear camera, all aspects were satisfactory.

System: bright and flexible, easy to use peace of mind

OPPO R11 runs the latest ColorOS 3.1 system. Overall, it is not a big difference from the previous version. It should only be a small improvement.

UI style and animation over, ColorOS 3.1 still follow the previous version of the design style, the more prominent difference is that the desktop's style has become more active, probably because the icon in the color is more bright and flexible, more young Change.

However, visual design is not an important factor in evaluating whether a system is easy to use. The mobile phone is a terminal of our personal information. First of all, it needs to provide a safe environment for use. ColorOS 3.1 inherits an excellent security experience. Any APP on the OPPO Mall has undergone multiple security checks and is manually detected. Almost 100% of the genuine APP rate can basically eliminate the harm caused by fake software.

Each mobile phone has a mobile phone butler to speed up, clear the garbage and scan for viruses. The interface of the OPPO mobile butler is very simple, and several functions are categorized at a glance. It is worth mentioning that WeChat is most commonly used by most of us. The chat tool will occupy a very large space for a long time. Therefore, if the capacity of your mobile phone is not large enough, it is necessary to regularly clean up. However, the OPPO mobile butler's WeChat special cleaning function just satisfies the requirements. User needs. At the same time, the butler also has a payment protection function to ensure the safety of mobile payments.

At the same time, ColorOS 3.0 also supports application avatars (settings - application avatars). At present, there are two applications, WeChat and QQ, that can be used to adapt this function. After opening a split, you can freely modify the name of the split application. The "Real Body" and "Split" applications can run simultaneously, and the data is completely independent.

For new mobile phone users, OPPO has also launched a mobile phone moving function, only need to gently scan through the two-dimensional code, you can complete the transfer of data, the entire process is very fast and convenient.

Performance: comparable to the previous generation flagship, ultra-fast network

OPPO R11 equipped with Qualcomm Snapdragon 660 processor, equipped with 4GB RAM + 64GB ROM, battery 3000mAh. In short, R11 is not a mobile phone with main performance. The hardware is in the mid-range position in the Android camp and can fully meet daily use. Although Snapdragon 660 supports LPDDR4 memory and UFS 2.1 flash memory, R11 uses eMMC 5.1 for flash memory specifications.

OPPO R11 performance test summary

Ann Bunny (General) Total: 118132 3D: 29828 Geekbench (CPU/GPU) Single Core: 1591/Multicore: 5846 GPU: 5540 Androbench (ROM) 4K Reading: 55.52MB/s 4K Write: 17.48MB/s

The OPPO R11 is the first model to use the Snapdragon 660. Although this processor is the successor to the Snapdragon 653, it is not the same architecture. Xiaolong 653 uses 4*A72 2.0GHz+4*A53 1.4GHz ARM public version of the architecture, while the Xiaolong 660 uses Qualcomm independent frame: 8*kryo 260, is also a size of the nuclear design, as a performance is very Approaching the Snapdragon 820's processor, the Snapdragon 660 is likely to replace Snapdragon 625 under the blessing of the 14nm process process, becoming the "God U" this year.

In addition to performance and power consumption, Qualcomm Snapdragon 660 also has a very Niubi thing - Xiaolong X12 modem, which is Modem.

Speaking of Modem, what is this thing in the end? In fact, this thing is to use the Internet and talk, although this feature has been achieved many years ago, but Qualcomm's titan is to be able to do Niubi things more arrogant, for example, the highest support downstream Cat.12 (600Mbps download bandwidth), upstream Cat.13 (150Mbps upload bandwidth), to know that the current domestic operators support Cat.6 at most. For example, if operators again accelerate this year, they have reached the Cat.12 standard, and the download speed has already reached 60MB per second, but since your mobile phone does not support Cat.12, you cannot enjoy such a fast speed. Now.

Recently, I had a cousin named Cucumber's cousin hooked up with a mobile game, called "The King of Pesticides," and it is said to be very hot.

However, you have to know that after all, cucumber's mobile phone is needed for work and life, so there are many telephone calls. Every time a phone call comes, the cousin has a tantrum with the cucumber: "Oh, it's dropped, and the cousin hates you oh~"

Everyone knows that every time we call, the signal will fall back to 2/3G. This is because 4G LTE technology does not support voice calls. In order to protect the call, we generally use the CSFB fallback technology to resolve the signal when the call is made. To 2G or 3G - this is why the cousin is always wrapped in cucumber. One of my colleagues, I think I should help cucumber, I said that you do not have enough to open a â€œfat bodyâ€ on your R11. After Cucumber heard my suggestion, it immediately opened VoLTE HD voice call service to your mobile phone. From then on, Cousin lived a happy and happy life.

Why is there no problem of falling back after opening VoLTE service? This is because VoLTE is similar to the WeChat and QQ calls in that it uses data traffic, but the difference is that VoLTE is a dedicated channel on the mobile data network. It has the highest priority in LTE networks and can guarantee the call. At the same time, there will be no problem of "dropping". The Xiaolong 660's integrated X12 Modem supports VoLTE call service, ensuring the continuity of conversation between Wi-Fi (VoWiFi) and LTE, and achieving a seamless handover between the two.

It is worth mentioning that the Xiaolong X12 LTE Modem also supports dual-channel WiFi. In simple terms, dual-channel WiFi has a larger coverage area, fewer signal dead angles, and faster transmission speeds. For example, one day when a cousin of a cucumber fell out of line while playing the king's glory in the toilet, and then spilled his temper on the cucumber body. No way, the cucumber had to think of a way to change the router to support dual-channel WiFi, with dual support Access OPPO R11 WiFi, from this cucumber and cousin to live a happier life.

After blowing water, the following summary.

On the whole, OPPO R11 will not have a big bottleneck in normal use. It can handle most of the popular mobile games (Wang Glory, Onmyoji, CF, and Collapse 3, etc.), and 4GB of memory can guarantee daily APP resident and More open, 64GB flash memory capacity is not large, for the camera party may not be able to meet.

Conclusion

OPPO R11's first Opteron 660 mobile platform has unparalleled performance under the 14nm process. Before and after the 20 million shots, a more clear and beautiful portrait was taken. Slim and small waist, micro slit antenna 2.0 and micro-arc back cover, fine work to achieve the balance of beauty.

In conjunction with ColorOS 3.1, which reinvents the aesthetics of order, OPPO elaborates on the understanding of the living fashion lifestyle. This time, OPPO R11 has both face value and strength.
