Have to say, in the direction of the smartphone screen, Vivo is definitely the forerunner, followed by X20 of 18: 9 and X21 using "Liu Haiziang", September this year, Vivo once again launched "water dripping screen Designed x23. What changes will be made to the bottom water dripping screen to make the internal structure of the phone? This detailed comment brings everyone to dismantling the VIVO X23.
Decomposition highlight:
Special medium frame design
6.41 inch Super Amoled "Water Dripping"
Fort-generation screen fingerprint recognition
Vivo x23 configuration list:
SOC: Qualcomm Snapdragon 670 processor
Screen: 6.41 inch AMOLED screen, 2340 × 1080 resolution
Store: 8GB memory, 128GB storage space
Front: 12 million pixel camera
Rear: 12 million pixels +13 million pixel camera
Battery: 3300mAh lithium battery
Preliminary dismantling:
Remove the SIM card slot, Vivo x23 is a rear demolition design, using a hot air gun to heat the rear cover and edge, and then remove the rear cover. When the rear cover is opened, it can be seen that Vivo X23 is still a classic three-segment design.
The rear cover and the middle frame are fixed by a large amount of glue, and the width of the glue is about 3.2 mm.
Unlike the X-series designer design, Vivox23 is a frame between the internal support and the rear cover to enhance the feel. The middle frame is fixed between the two hexagonal screws and the bayonets in the bottom.
The BTB interface on the motherboard has a metal plate for cover protection, and on the metal cover of the BTB interface covering the camera, the panel is also attached to the soft board for connecting the handset module and the motherboard.
Disconnect and remove the soft board, the battery is fixed by transparent glue, and the battery is equipped with a pull strip for easy disassembly.
There are many waterproof designs in the whole machine, such as headphone holes, SIM Carto and USB interfaces.
Silica collishers that are used to reduce voices in the groove of the vibrator to reduce vibration.
The screen soft board passes through the inwardly supported gap, but this silica pad is mainly suitable for the position of the fixed soft plate.

Overall, the overall design of VIVO X23 is not very special, so the motherboard design is also more typical. It is worth mentioning that the yellow portion of the front of the motherboard is a storage combination of Vivo X23. There is also 8GB memory + 128GB flash memory, so we did not see the stack package craft on the motherboard of Vivo X23, but At the same time, such a "big" block element also played a safe role.
"Water Drip" design:
Vivo x23 is equipped with a 6.41-inch Super AMOLED screen from Samsung, with a screen resolution of 2340 × 1080, and the screen model is AMS6411WC01.
This screen is supported by black gums, while the internal support is also laid in large-area foam to help heat dissipation. As can be seen from the figure, the design of this screen is only a small opening in the front, and this small opening is the pre-camera position in the "water drip screen".
Screen down fingerprint recognition:
The Vivo x23 is used as the fourth generation fingerprint recognition scheme. Compared to the previous scheme, the largest highlight of the fourth-generation fingerprint recognition scheme is that it uses an F1.5 aperture camera to finish the collection and identification, so that the recognition accuracy and the recognition speed are greatly improved.
The specific working principle is to obtain information by a two-piece screen under the screen, and then pair the information, thereby reaching the screen fingerprint recognition. According to official claims that this generation of fingerprints can be unlocked with only 0.35s, which is 40% higher than the previous generation speed.
Rear camera:
In terms of the rear camera, the rear double-fitting of the Vivo X23 is a main camera 12 million pixels and a sub-camera 13 million pixels. Among them, the main camera model is Sony IMX363, and the sub-camera uses Samsung S5K3L6. It is worth mentioning that the sub-camera uses a super wide-angle lens at 125 ° perspective, which is also the first to join the super wide angle camera in the history of smartphones.
Vivox23 BOM table:
Vivo x23 8GB + 128GB version of the national line is priced at 3498 yuan.
It can be seen from the BOM table that the VivoX23 components are some of the more mainstream vendors. Among the components provided by these mainstream vendors, the most concerned, thinking about the Snapdragon 670 processor.
Although in naming, the Snapdragon 670 seems to be the "upgraded version" of Snapdragon 660. In fact, the Snapdragon 670 seems to be more like the "shrink version" of the Snapdragon 710 whether from the process or performance. Integrated Hexagon 685 DSP vector processing unit, SPECTRA 250 ISP, maximum support 8GB DDR4X memory, AQSTIC audio technology, and QC 4.0 fast charge, Snapdragon 670 is in Qilong 710.
According to Qualcomm official, under the "blessing" of the 10nm LPP process, the AI performance of Snapdragon 670 is 1.8 times the Snapdragon 660, and the CPU performance has increased by 15%, and GPU performance has increased by 25%. Such a strong performance, so that many people believe that the Snapdong 670 will perfectly manipulate the clothes of the dragon 660, becoming a new generation of "God U".
The whole machine parts are taken:
Demolition rating of Vivo X23:
Summary:
Vivo x23 uses a common three-stage structure, and internal design is still "stronger", and there is no innovation. However, from the hardware configuration, screen, wide angle camera, then to disassembly is to see the internal system, a large number of metal plates and silicone pads to protect, heat dissipation, waterproof design, etc., it is not difficult to see Vivo on X23 A lot of thoughts spend.
