Foreword: Vivo's first "full screen"?
The vivo X20, as a new "full screen" mobile phone of vivo, focuses on "backlight photography". What other features do it have? What about the performance of the vivo X20, which is known as the "most conscientious" price? Messi will show you!
| Unpacking: not stunning, frivolity is the keynote
——————————————————————————————————————————
The vivo X20 (128G version) is top equipped with black gold color matching, and the package is the icon titled 2018 World Cup (Dachang advertising heroism).
Open the package: vivo X20 mobile phone, wired headset, USB cable (Micro USB), 18W quick charger.
The front of the vivo X20 uses the 18:9 6-inch Samsung Super AMOLED screen. The design is not stunning without borders, but fortunately the overall screen accounts for 85% (middle and upstream level). The factory has a film, which can be used directly.
The top left side is a front camera with 1200W * 2 pixels using Samsung S5K2L9 sensor, and the symmetrical right side is a soft light.
The width of the X20 bottom bar is similar to that of the top, without any buttons or brand logos. It is simple.
The bottom of the vivo X20 continues the traditional design of the previous X9, retains the 3.5mm headphone hole, and the charging port is still the Micro USB port. I don't know when I can get on the "USB Type-C car".
The appearance design of the vivo X20 is basically the same as that of the previous generation. It is still light and thin, which is my impression of its feel. It seems that only offline OV/Jinli is still pursuing light and thin.
The 6-inch screen and 5.5 inch hand feel are not praises, but the real situation. Generally, 5.5 inch mobile phones have a weight of 150-160g, and there are many overweight players like the iPhone 8P (202g), like the Xiaomi MIX2, which is much heavier.
The vivo X20 adopts the 500+2 * 1200W scheme and supports the full pixel dual core focusing function. The 2 * 1200W pixel sensor is the same as the front one, but the aperture is larger than F1.8. Unfortunately, there is no optical anti shake and independent ISP on the X20 Plus, so the overall effect may be discounted.
| X20 full screen: wide field of view, high brightness
——————————————————————————————————————————
The vivo X20 uses a 6.01-inch Super AMOLED screen with a 2K resolution. At present, the Samsung Super AMOLED screen has a high stability, and will not burn the LG (OLED) screen on the Pixel 2 XL.
Compared with the 5.5 inch Meizu Pro 6s (left), the vivo X20 (right) does not seem to be more bulky, and the narrow forehead is not innovative, but it still has some improvement in vision.
The measured peak brightness of vivo X20 is 593nit, which is high and can meet the demand of bright light in the daytime.
Compared with the LCD iPhone 6, the OLED X20 has certain advantages in black field and contrast.
By comparing Meizu Pro 6s (the same as amoled), we can see that X20 has higher color saturation, rosy face and "please the eyes".
In the blue scene and the following sunset scene, we can also find that the X20 screen display color is better than Meizu Pro 6s, and the color is more beautiful, but not particularly "rich".
| X20 performance: "the best pesticide machine"&"eat chicken happily"?
——————————————————————————————————————————
Vivo X20, as the official machine of "KPL" (King's Glory Professional League), is it just a title, or is it really capable? Messi, a "severe pesticide patient", measured it for you personally.
By comparing the Snapdragon 821 (the flagship of the previous generation) and the Snapdragon 820, we can see that this year's Snapdragon 660, the king of the mid tier, is very close to the performance of the Snapdragon 821. Based on the 14nm process, the power consumption also has some control. All Messi are very interested in this mid tier "God U".
Stabilizing 60 and killing everywhere?
Although most of the flagship 835 mobile phones currently support the high frame rate mode of Glory of the King, there are few real group battles that are stable at more than 55 frames. For example, the Xiaomi MIX2 that supports the high frame rate will drop to about 40 frames in group battles and cannot maintain 50 frames.
When Messi measured vivo X20 playing pesticide, after more than 30 actual battles, the results proved that X20 had excellent stability in the regiment war, and the whole process was more than 55 frames.
Game mode: small optimization
In addition to the BUG like "frame number", vivo X20 also has a "game mode". After the game mode is turned on, you can call out WeChat/QQ operations through specific gestures to support any game installed in the mobile phone, which is more human.
I believe that a friend has met the situation of GG when calling together. X20 has a phone reminder function, but it seems that actually it can't talk while playing games. After answering the phone, it automatically switches to the call interface.
Jungle Rules: "Eat Chicken" in Mobile Edition
In the game of "Eating Chicken", the special effects are all on, and the frames of X20 are between 40-50, which is relatively stable. "Tencent Dad" has released a mobile version of "Eating Chicken", and I wonder whether X20 has followed the "optimization".
Collapse 3: "Burning 3D":
Crash 3 is the current and NBA 2K 17 level blockbuster. After the special effects are fully turned on, the X20 frames are 35-40 frames. The data is not particularly beautiful, but the smoothness of play can be guaranteed.
Vivo X20 really has two brushes, especially the "King's Glory" optimized by "My Father". After the double height game is started, the group war can still maintain more than 55 frames of terrorist data (which can't be done even after 835), which is very suitable for "pesticide players". Xiaolong 660 can actually "eat chicken" with high image quality. The number of frames to play Collapse 3 is average, but it can also cope. For vivo, who has been complained about by "low configuration" for a long time, this X20 style is not "big factory".
| FaceWake (face recognition): fast, safety to be optimized
——————————————————————————————————————————
At present, except that iPhone X has completely abandoned "fingerprint recognition", other manufacturers' "facial recognition" schemes are only a supplement to "fingerprint recognition". Face unlocking is used to reduce the operation difficulty of back fingerprint unlocking. Vivo X20 is no exception, and plane scanning is used for unlocking.
1. Unlock: fast, high success rate
Judging from the actual success rate of unlocking, vivo X20 has done a good job. The unlocking speed is very fast, and the success rate in dark scenes is 7-80%.
2. Safety: certain guarantee, but still need to be improved
Through computer photos, Messi found that it could not be unlocked. Of course, there are videos of media unlocking mobile phones on the Internet. Messi can only say that it is difficult for ordinary people to unlock.
Although it is difficult to "cheat" to unlock X20, Messi found that vivo X20 can also be unlocked with eyes closed, which means there is a risk of being "secretly unlocked". It is recommended that vivo still be set to unlock with eyes open.
| Back light photography: force in front, middle in back
——————————————————————————————————————————
Daytime proof sheet: The white balance is more accurate, and the color is more realistic.
Night shot: medium flagship level
Filter: The vivo X20 is better than the MIX2 of "photographing black holes", but the light star is also more obvious.
Analytical force: Compared with Xiaomi MIX2, X20 has stronger analytical power, at least able to distinguish brick joints.
Noise reduction: Since the vivo X20 does not support optical anti shake and does not have an independent ISP, especially in night photography, because X20 lacks anti shake function, the film rate at night is average, and there are many waste films due to shake, so taking photos requires more patience.
The overall picture purity is acceptable, without the redness of MIX2.
Ps: vivo X20 In some scenes, white balance offset occurs, such as the cup below.
Virtualization: The figure virtualization is still in place, and the still life virtualization has a "rollover" situation.
Backlight photography: satisfactory effect
Vivo X20 mainly focuses on backlight photography. Seen from the front photo, under the strong indoor light and outdoor sunlight behind, the X20 can really maintain the contour and details of the face, and will not be "black" like many mobile phones.
At night, thanks to the front soft light, X20 has higher photo availability than Xiaomi MIX2 under strong direct light.
The photo on the right side is slightly overexposed in the same big backlight environment, but the overall details of the two photos, especially the inside of the camphor tree and the eaves, remain more detailed, and the overall photo is also bright.
Photo summary:
Both Vivo and OPPO regard "selfie" as the biggest propaganda point of mobile phones. The backlight effect of the Vivo X20, which has been working on the front camera for many years, is really good to tell the truth. The night photography effect has also reached the flagship level, but the lack of independent DSP and optical anti shake also doomed his photography ability to not reach the first-class level in the flagship.

——————————————————————————————————————————
The battery capacity of the vivo X20 is 3300 mA. Thanks to the Snapdragon 660, the amoled screen and its own positive optimization, the 6-inch X20 can last for 1-1.5 days, charging 9V/2A, and the actual measurement can reach about 17W.
Summary vivo X20
——————————————————————————————————————————
The vivo X20 may be the least "low configuration and high price" product in vivo. Although its appearance and functions are not amazing (the UI is still very iPhone), it also lacks the previous performance shortcomings. At least most of the experience performance of this generation of Snapdragon 660 can satisfy most people. "Pesticide optimization" and "backlight photography" are the two biggest surprises for me.
If you like "thin", "pesticide" and "self portrait", do not care about NFC and do not demand rear photography, and can accept 2799 (64G) positioning, then the 64G version may be a good alternative.
