At the end of last year, OPPO not only launched the R11s / R11s Plus, which mainly focuses on night shooting dual mirrors and AI smart beauty selfies, but also the large-screen version of the Plus has finally been introduced to Taiwan, giving consumers more choices. Following the launch of the R11s Plus a few days ago, the A75 / A75s products, which are positioned at the middle-class distance, are also on sale at the same time; they have the appearance style of the R11s, and the 18:9 full-screen display. The biggest highlight should be It is an AI smart beauty selfie.

After talking about the boxing, let’s go back to the phone body. The appearance of A75 and A75s can be said to be exactly the same (in fact, there is only one difference in specifications), and the front of the fuselage is equipped with a 6-inch 18:9 ratio screen with a resolution of 2,160 x 1,080, which is also called a full screen (cancel Home entity). button); but it is still a bit obvious up, down, left and right, but the black style will be better than the white one in terms of visual experience on the screen (the effect of the black screen is better). The screen is also affixed with a protective sticker when it leaves the factory, which should be commended.

The design on both sides of the fuselage is the same as that of the R11s. The left side is the volume button BD6376GUL-E2, and the right side is the power on/off button; the upper card slot is the highly practical nanoSIM + microSD three card slot; as for the bottom of the machine is equipped with 3.5mm headphone jack, microUSB port and speakers, but there is no "Crescent Bay" groove design of the R11s. (By the way, looking at the edge of the screen and the fuselage from the side, it actually feels familiar.)

Function introduction

The built-in operating system of the A75s is ColorOS 3.2 based on Android 7.1. Like the R11s, there is basically no difference in the operation functions. Here are a few special items for everyone to review. First of all, the A75s also has built-in fingerprint and Face recognition, the overall response is almost as fast as the R11s (but one thing is missing). Interested netizens can go back to the previous experience of the R11s and have a look, let Xiaobian quickly introduce other functions.....

Navigation keys

In response to the removal of the Home button, the A75s is the same as the R11s in operation - you can call the Home, Return and Multitasking buttons from the virtual buttons and the iPhone X-like swipe gestures. It should be noted here that the virtual buttons can be used. Hidden; but it cannot be operated by gestures after being folded, and you need to call out the virtual keys to use it normally.

Gesture operation

The functions that can be activated by various gestures when the screen is off can also be seen on the A75s, such as drawing a pattern to open the camera, flashlight, or customizing the APP, but compared with the R11s, the screen will light up without picking up the phone. From now on, it can only be turned on by tapping the screen twice, and it is a pity that the smooth action of holding the phone -> unlocking the screen cannot be completed with facial recognition.

It is a picture-in-picture that Android must have at present. After the A75s is turned on, it can be turned on in the multi-tasking mode (on the side is the lock APP, which can prevent it from being removed from the background mode). After opening, you can freely adjust the screen size (up to about 70%); but not every APP supports split mode, you need to pay special attention (like LINE, Facenook will not).

control center

Some Android models of "genre" will have their own version of the master control APP. On the OPPO side, it is called the mobile phone housekeeper. It has basic privacy settings for clearing temporary storage, encrypting the APP, and setting permissions. , as well as anti-virus and other functions, there are also payment protection functions (but this machine does not have NFC.....).

Monitoring and Real Acoustic Technology

In terms of sound effects, the A75s has not only the earphone monitoring function that can be used with the K song APP and microphone, but also the Real acoustic technology function similar to the EQ equalizer effect. It has 11 built-in (including custom) music style settings, which are actually matched with dance music. Listening to the EDM songs, the bass really stands out a lot.

OPPO mutual transmission

When I introduced vivo v7+, I detected its own mutual transfer APP. There is also an "OPPO mutual transfer" function on the OPPO side. You can choose photos or videos for transfer. Before transferring, another mobile phone needs to open the OPPO in the control center. Mutual transmission, the transmission will be automatically started after receiving, no need to connect to the network during transmission, but the mobile phone will turn on Wi-Fi and Bluetooth functions.

battery life

The A75s has a built-in 3,200mAh battery, but does not support VOOC flash charging. The accompanying transformer is 5V 2A. According to the power test item of PC Mark, the result is 9 hours and 27 minutes, which is considered to be an upper-middle level. Charging from 18% with the included accessories takes about 2 hours and 9 minutes to fully charge.

Shooting performance

The A75s has the same shooting specifications as the R11s dual-camera, which should be the 20-megapixel f/2.0 front lens blessed by AI smart beauty. The main lens is slightly down to 16MP f/1.8 (R11s is 2,000 + 16MP, both f/1.7). The editor himself thinks that the A75s is a more interesting lens than the previous lens, so I will introduce the Selfie function first. The interface part is almost the same as the R11s, so I will not introduce more here, but the A57 does not have the watermark of the R11s Logo. general style only).

beauty

From the perspective of specifications and functions, the front lens of the A57s and the R11s are almost identical, with specifications such as Level 6 beauty and AI beauty. Here, let’s take a look at the performance from zero to the maximum level 6, as well as the performance of smart beauty. In fact, after starting from level 4, although the microdermabrasion effect is a bit excessive, the overall finished product is not too exaggerated. If you are lazy, you can directly open it. The AI wisdom effect is already very natural~

Bokeh

The front lens of the A75s supports the portrait blur function (no double, only blur), although it does not support the main lens of the R11s; but the overall algorithm seems to be pretty good, most of the complex backgrounds have been successfully counted, only The fingers and edges of leaves in a few photos are more prone to flaws. When used for relatively simple backgrounds, the results are actually quite good; however, the main lens does not support the blur function, which is a common problem with many mid-range cameras. (You can't help your girlfriend to take pictures, you can only ask your girlfriend to come by herself)

Main lens real shot + HDR

The image quality of the main lens of the A75s tends to be at the level of the average mid-range camera. The image quality is not bad in an environment with sufficient light sources, but there are some smear marks when zoomed in. The effect of HDR is quite obvious. The dark parts of objects, sky clouds and other details are highlighted, but sometimes due to the relationship of color toning, the overall effect is slightly thicker, and the HDR effect is a bit surreal in some situations.

Although the A75s has the same 2x zoom switch as the R11s dual camera, the principle is the same as the digital method (the R11s becomes a night shot, after all, there is only one lens). In fact, compared with the R11s Plus, the difference between the two is not too big in a dimly lit room at normal focal lengths; but after converting to 2x zoom, it can be found that the A75s has a more serious reduction in image quality.

Epilogue

Overall, the A75s dual-machine is not difficult to see the strong figure of the R11s in the body and interior, and it is not an exaggeration to say that it is a "little brother". There is almost no difference between the internal OS and many functions (except for the function of not picking up the screen to light up); although the performance of the main lens is slightly ordinary, but the front lens and AI smart beauty inherited from the R11s, the performance is the same as that of the R11s dual-camera. There is nothing wrong with it. If you want to change to a mid-range selfie camera, it seems that you can consider it.
