Vivo officially released vivo X9s and X9s Plus on the evening of July 6 in Beijing. This new product mainly focuses on the enhancement of thinness and 20 million front dual camera. We Love to play computer games We also got vivo X9s and X9s Plus at the first time. Now let's take a look:
Appearance and packaging
The packaging of vivo X9s/X9s Plus is similar to that of the previous generation. It is a pure white cardboard box with reticular grain. The logo has blue embellishment and the logo of NBA official partners. Accessories include instruction manual, clip, transparent silicone shell, dual engine flash charging head, mirco USB data cable, headset and its supporting silicone cover. It should be noted that the charging head of this generation is unified into BK-T-01Q, with a maximum output of 9V/2A and 18W.
What we have here is the gold vivo X9s and black X9s Plus. The front outlines of the two machines are the same as those of the previous generation. The narrow frame on the white front panel will be more impressive, while the black front panel will be more integrated.
The most obvious feature of the vivo X9/X9s series is the front dual camera aperture on the left side of the receiver. This year, the front of the vivo X9s and X9s Plus has been changed to 20 million pixels+5 million pixels. The main front camera is the IMX376 customized with Sony, 1/2.8 inch, 1.0 μ m per pixel.
The home key cannot be pressed, which is slightly lower than the screen. The zirconia key cover plate and the screen glass panel have a slight color difference. In addition, Vivo X9s and X9s Plus come with their own film, and the latter is upgraded to tempered glass film, which is a very rare operation.
After the screen is lit, the white version of the frame is still more shocking, and the screen is more colorful.
The X9s maintains the design of a U-shaped antenna, with a slight radian on the back of the body and excellent grip.
The antenna color difference of the black version is smaller, and the integrity is stronger. The vivo X9s and X9s Plus are equipped with a 1/2.8 inch 16 million pixel sensor on the rear. The former uses Samsung's S5K2P7, and the latter uses Sony's IMX298.
The vivo X9s Plus has one more noise reduction microphone opening than the X9s. The bottom interface layout is consistent. From left to right, there are headphone interface, main microphone, mirco USB and speaker. Vivo and OPPO, two big blue and green manufacturers, are the only big manufacturers that still insist on using the mirco USB interface. Interesting details are that the X9s have a more rigid waistline on the side, while the X9s Plus has a more rounded side.
It is also the classic left sim card slot, and the right volume and power buttons.
system
The system of vivo X9s and X9s Plus has been upgraded to the Fontouch OS 3.1 of Android 7.1.1 kernel, adding advanced functions such as game keyboard, game free, global soft light, enhanced split screen multitasking, child mode and application double opening.
The desktop, control center, notice bar, multi task and other sections have not changed much
Official applications such as weather, music and application market are still flat and simple
The split screen of the new system is based on the new features of Android 7.1.1. Long press of the multitask button trigger can be used in selected apps such as video and chat applications, while the native double click multitask button switching function will automatically locate the previous application in the multitask card, which is slightly different from the common one.
Front camera
Vivo is one of the few manufacturers with more setting parameters for front camera than rear camera
screen
The X9s is equipped with a 5.5 inch 1080P AMOLED screen, which can cover 143.2% of the sRGB color gamut with a color temperature of 7632K under the commonly used 100 nit brightness. In terms of sRGB color standard, the average deltaE of 104 colors is 4.8, and the maximum is 10.4.
The X9s Plus is equipped with a 5.85-inch 1080P AMOLED screen. Under the commonly used 100 nit brightness, the color temperature is 7443K, which can cover 143.8% of the sRGB color gamut. It is also rich in color, but the color temperature is slightly warmer. In terms of sRGB color standard, the average deltaE of 104 colors is 6, and the maximum is 10.1.
New audio chip ES9318 Blessing
X9s Plus uses a new audio SoC - ES9318, which is an upgraded version of ES9218 (the legendary Quad DAC) on LG V20. This chip comes with its own DAC and AMP modules. The measured sound level is really good. Although its quality is not as high as that of Xplay6 when playing normally without damage, it is quite excellent compared with other competitors. In addition, we found that the X9s Plus also supports the playing of DSD files in HiFi mode, that is, it performs DSD hard solution through ES9318. The effect is even better than that of Xplay6 playing DSD files, which is a big surprise.
beat Upgrade as
X9s Plus's CMOS is Sony's IMX298
X9s CMOS is Samsung S5K2P7 (its specific parameters are consistent with IMX298)
X9s Plus live shot highlight proof
X9s Plus Real time Backlight Sample
The X9s Plus is equipped with its MWC Asia 2017 customized DSP chip, the latter has 256MB of memory, which can tell to synthesize multiple RAW photos and output normal jpg pictures. The direct effect is to greatly improve the highlight performance of large light difference scenes and the speed of multi frame synthesis.
In practical experience, the HDR multi frame synthesis speed of the X9s Plus is certainly the fastest of all mobile phones at present. HDR is no different from ordinary photography in terms of shutter, composition and preview. This is a speed that even Samsung S8 and iPhone cannot achieve.
Enlarge the sunset backlight details
The vivo X9s and X9s Plus both have an automatic HDR function. Among them, the X9s HDR judgment will be more sensitive, while the X9s Plus with higher tolerance will only trigger HDR in large light difference scenes. HDR requires hand stabilization+optical anti shake to ensure the film rate. Normally, the HDR speed of mobile phones is slow, so even if the film rate is low, there will not be too many waste films (too slow to press the shutter several times).
However, the HDR processing speed of the X9s Plus is too fast. The shutter is still like a machine gun, but it will produce more waste films. This is a paradox brought about by the new technology. However, the highlight and dark details of the whole film have been improved immediately. The effect of this DSP with RAM is more practical than that of most manufacturers' double cameras. It is estimated that many manufacturers will follow up soon.
The detailed product evaluation will be completed in the near future, please look forward to it.
