Z series is a new series launched by Vivo in 2018, and Z3 is Vivo's exclusive model in the Internet channel, its previous generation model is Z1 launched in May, because its configuration is on par with Vivo X23, the cost performance is relatively higher, if it is sold offline, it will affect the sales of X23.
 
In terms of appearance, the back of the Z3 is very close to that of the Vivo X21, with the difference that the Z3's camera and fingerprint recognition have a circle of metal frames that are out of line. The plastic shell has been treated with gradient color, which belongs to the regular operation of Vivo, and the edge of the 3D micro-arc feels rounded and the grip is good, but the plastic will be worse in terms of texture. The bottom retains a 3.5mm headphone jack and a Micro USB charging port.
 
The screen on the front is Vivo's recently commonly used water drop screen,This water drop integrates a light sensor、Camera,There is a hidden infrared light next door,The unlocking speed of facial recognition is fast,It can also be unlocked in a dark environment,But the security is not enough to meet the face payment。 The screen is more prominent than the fuselage,There is a drop between the edge of the screen and the middle frame,The transition is not smooth,When you hold it,The touch of the fingers will be a little strange。 The screen at the edge of the water droplet will be a little dim, and the transition between the water droplet and the edge of the screen is not very natural, so it is recommended to set the water droplet to be hidden.

The default color temperature is over 8000k, the hue is cool, the maximum brightness is 430 nits, and the color gamut covers more than 100% sRGB and 82.5% DCI-P3. In the sRGB color gamut, the average DeltaE is 4.6 and the maximum DeltaE is 10.6, which is within the normal range, but the deviation of the maximum value is a bit large. Compared with models of the same level that use LCD screens, the Z3 does not use a notch design, and the bezel is narrow enough, and the large screen-to-body ratio is also an advantage.

What's more, Z3 has launched a Dual-Turbo engine specifically for games, that is, a game acceleration engine system acceleration engine, a good hardware foundation and software optimization, the game performance will be even better.
 
In terms of photography, the main camera of the Z3 is the 16 million IMX499, which does not have Super HDR, but also supports HDR. In daytime use, the image quality is high, and the details of the shadows can be preserved in high-contrast scenes, the picture is bright and clean, and the imaging in low-light scenes is a little worse, especially in the night scene, it is difficult to retain the details of the shadows. The playability of the front 12 million pixels is very high, and the beauty function is also very suitable for female consumers, and the adjustment options for the facial features are very detailed, which can be said to be a facelift-level beauty function.
