In 2017, "full screen" mobile phones were rapidly popularized. To use full screen mobile phones and achieve fingerprint recognition, the post fingerprint solution was almost the only option (there were exceptions, for example, iPhone X gave up fingerprint recognition directly). However, vivo displayed a new mobile phone X20Plus UD (screen fingerprint version) with offline fingerprint at CES 2018, which was officially released in China on January 24, and will be officially launched in February in the twinkling of an eye. How about this one with the latest "black technology" experience? Let's take a look:

Unpacking and appearance

The packaging shape of the vivo X20Plus screen fingerprint version is exactly the same as that of the X20 series, but it uses the black gold tone, which echoes the color matching of the mobile phone itself. In addition, there is an obvious "fingerprint" pattern on the outside of the package for decoration.

Open the package and you can see the real phone of vivo X20Plus screen fingerprint version. The phone is equipped with frosted protective film. There are important tips on the film. When using non original protective film, please do not block the screen fingerprint area, which means that this phone still has a high requirement for film sticking.

The front appearance of the vivo X20Plus screen fingerprint version is the same as that of the vivo X20Plus. The 6.43 inch Samsung AMOLED screen gives a strong visual shock. If you turn on the off screen clock function, we will see the identification of the fingerprint identification area on the mobile phone screen. What we get is the experience machine, and there is no film. The official retail version will be pasted with a film dedicated to the vivo X20Plus screen fingerprint version.

Due to the 18:9 panel and narrow border design, the entire size of the vivo X20Plus screen fingerprint version is about the same as that of a traditional 16:9 phone with a 5.85-inch screen. However, there is no doubt that this is a phone with a larger size. In terms of hardware configuration, it is completely consistent with the regular version of vivo X20Plus. The Snapdragon 660 processor is equipped with 12 million pixel dual pixel sensors (specific model is Samsung s5k2l9, unit pixel area is 1.28 μ m), 4G memory, 3905mAh battery, ES9318 audio chip, these have not changed, but the vivo X20Plus screen fingerprint version has only one version for the time being, with a storage capacity of 128G, and the body uses black gold color matching.

The fuselage adopts black gold color matching. It can be seen that the polished sides of the metal integrated fuselage are decorated with gold.

The vivo X20Plus screen fingerprint version does not "dig holes" in the back to achieve fingerprint identification like the ordinary version. Its fingerprint identification area is in the screen, specifically below the 0.68mm glass cover, OLED glass layer and OLED light-emitting unit. Fingerprint identification is achieved through photoelectric reflection technology. The supplier of fingerprint identification sensors is Synaptics (New Ideas International).

There is no fingerprint identification on the back of the fuselage, which seems to be more harmonious and simpler in design.

Other accessories in the package are the same as the ordinary version, including XE680 headset, microUSB data cable and a 5V 4.5A standard 22.5W low-voltage fast charge (fast charge can only be achieved with a special data cable). The charging speed has great advantages over ordinary mobile phones.

System and fingerprint experience

The vivo X20Plus screen fingerprint version uses the FontouchOS 3.2 based on Android 7.1.1, which is not very different from the general version in terms of system.

A new "Smart Wake up Fingerprint" is added in the fingerprint setting option, which is a new function set for fingerprint under the screen. It wakes up the fingerprint sensor of the phone by sensing the phone action.

The offline fingerprint entry process takes longer than the traditional fingerprint, and requires a little effort to identify.

By default, the unlocking action wakes up the fingerprint identification area through the action (small shaking), and then the fingerprint can be unlocked. The whole process is relatively fast, but it needs some adaptation time in use.

Similarly, we can double click the screen to light up the screen to achieve the unlocking action. The whole process is more convenient than action wake-up.

Finally, you can also turn on the screen off clock function. When you turn on it, you will find that a fingerprint identification area will reside at the bottom of the screen. This is the most convenient way to unlock, but it will consume a little more power.

The vivo X20Plus screen fingerprint version brings us a new form of full screen mobile phone with fingerprint identification. As far as the product itself is concerned, it continues the features of large screen, soft light dual camera and HiFi chip. The price is also relatively friendly compared with the ordinary version (retail price is 3598 yuan). Users who want to buy X20Plus in the near future may consider this screen fingerprint version. It is estimated that vivo will also use this new technology in higher level Xplay series, which will give more possibilities for fuselage design. In 2018, It is believed that the technology of offline fingerprint will also be used by more and more manufacturers, and this new operation mode will certainly bring a new trend. As the vanguard of many new technologies, vivo has indeed brought us many new surprises and new stimuli.
