On March 17, OPPO released this year's R series new product OPPO R9 at Beijing National Performing Arts Center. This OPPO R9 uses a very narrow border design, a front fingerprint identification module, a 16 million pixel front beauty camera, and the new Color OS 3.0. Compared with OPPO R7, OPPO R9 brings us a more complete and ultimate experience.
In terms of parameters, OPPO R9 uses a 5.5 inch 1080P AMOLED screen, the SoC is MT6755, the CPU is 8 * A53 (2.0GHz), 4GB RAM+64GB ROM (supporting Micro SD card expansion), uses a rear 13 million pixel+front 16 million pixel camera, the rear camera sensor is Samsung S5K3M2, still supports VOOC flash charge (5V/4A), and is equipped with a front fingerprint identification module, It supports all Netcom+dual card and dual standby, with two colors of gold and rose gold.
appearance
OPPO R9 uses an outer packaging box similar to OPPO R7. After opening the packaging, we can see an OPPO R7 body, a headset, a VOOC flash charger, data lines, pins and instructions.
OPPO R9 adds a Home key with fingerprint identification module on the front, and two touch keys are on both sides of the Home key. The power key of the machine is located on the left side of the machine body, and the volume key is located on the right side of the machine body. At the bottom is a 3.5mm headphone interface, Micro USB interface, microphone and speaker opening. There is a 13 megapixel camera on the back, and a flash light is below the camera.
OPPO R9 adopts the appearance design of all metal edging, 2.5D curved glass, and the metal partition strip passes through the camera ingeniously without dragging mud and water. Because of the overall design style of OPPO R9 and the slightly protruding camera behind it, we can smell the flavor of iPhone 6s.
OPPO R9 adopts an extremely narrow 1.66mm frame design. The white edge on the front of the screen+the black edge on the back of the bright screen is only 1.66mm in total, which is much narrower than many mobile phones on the market that are known as "ID without frame".
OPPO R9 is also equipped with a 5V/4A VOOC flash charger as standard, and a special USB cable. In the case of VOOC fast charging, it only takes 10 minutes to charge from 0% to 20%.
screen
OPPO R9 uses a 5.5 inch 1080P AMOLED screen. In manual mode, the maximum brightness can reach 334nits, the color gamut can reach 142.8% sRGB, the maximum brightness is the average color temperature of 7342, and the gamma curve is 2.11. Needless to say, the contrast of AMOLED is close to infinity.
System UI
OPPO R9 adopts a new Color OS 3.0 system, which is based on Android 5.1. Color OS 3.0 is simpler than OPPO R7s' Color OS 2.1 system, and the UI style has also changed. Color OS 3.0 The system, as its name suggests, is very beautiful and eye-catching. The color of the system matches with the AMOLED screen, giving people a pleasant and relaxed feeling.
OPPO has simplified the operation on Color OS 3.0 and deleted some unnecessary interactive interfaces. The whole system is more than 100 MB lighter than Color OS 2.1.
performance
In terms of performance, OPPO R9 adopts MT6755 SoC, CPU is 8 * A53 (2.0GHz), GPU is Mali-T860MP2 700MHz, and memory is 4GB LPDDR3 933MHz. Compared with the MT6752 SoC of OPPO R7s, the performance of the MT6752 SoC is improved to a certain extent. Because the machine adopts a resolution of 1080P, the demand for memory bandwidth is not high, and the 7.4GB/s of the MT6755 is enough for daily use.

The rear camera of OPPO R9 is 13 million pixels, and the sensor model is S5K3M2. From the daytime samples, its daytime imaging white balance is relatively accurate, and its analytical power is at the mainstream market level of 13 million pixels. Due to the sufficient daytime light, its ISO is basically maintained within 100 in the automatic mode, with little noise.
Since OPPO R9 is not equipped with optical anti shake, the imaging performance at night is general. In the case of extremely weak light, some color noise will appear, but there is no problem with the white balance at night. Although there is no optical anti shake, OPPO R9 can effectively control the noise of nighttime imaging through smearing algorithm in some nighttime samples.

The front camera of OPPO R9 is 16 million pixels. The system has the function of beauty selfie. There are 7 levels of beauty effects from white to red. Beauty can be adjusted according to their own needs. From the front sample, the beauty camera of OPPO R9 can really paint the details of the beautiful woman's face to a large extent. Without changing the exposure, the shadow, pockmarks and dark spots on the face are all painted white. The specific effect depends on the environment at that time and the self timer.
Endurance&fever
In terms of endurance, although the battery capacity of OPPO R9 is 200mAh less than that of OPPO R7s, thanks to the light system and endurance optimization of Color OS 3.0, the remaining power of OPPO R9 is significantly more than that of OPPO R7s in our 3.5 hour endurance test.
In terms of heating, after running NBA 2K15 for one hour, the highest temperature of OPPO R9 appeared on the top of the fuselage, at about 41.9 ℃, which was in good order.
fingerprint identification
OPPO R9 vs. Galaxy S6 edge+
OPPO R9 used the positive fingerprint identification module this time. Although the official did not publicize this fingerprint identification too much, the author always believed that it was the biggest highlight of OPPO R9 this time. OPPO R9 uses zirconium gem as fingerprint key material, which has 8.5 Mohs hardness and higher dielectric constant than sapphire, making fingerprint identification more sensitive.
Previously, some netizens thought that OPPO R9's fingerprint unlocking eliminated excessive animation, which made it appear that "fingerprint unlocking is very fast". So in the test, we chose Samsung Galaxy S6 edge+, which also does not have excessive animation of fingerprint unlocking, for testing. We compare the screen off and screen on With the fingerprint unlocking speed of both, OPPO R9 takes the lead by a large margin
summary
OPPO R9 adds fingerprint and selfie on the basis of R7. The border is narrower and the system is simpler. Although the performance is not improved much, it is one of OPPO's strategies. As multi-core mobile phones are everywhere, it is difficult for consumers to intuitively understand the performance of a mobile phone offline. OPPO places the improvement of mobile phones on the appearance, process, fingerprint, selfie and other aspects. These factors that can even be ignored online are the most concerned points of offline users.
