The vivo NEX, equipped with a full-screen full-screen and lift-type front-facing camera, has received a lot of attention. Some people like its appearance, while others are immersed in its structure. What kind of innovation is Vivo NEX in its interior design? Point, let the vivo NEX become so beautiful? Immediately dismantle one, reveal it for you. (PS: Disassemble is risky, it is not recommended for users without experience to disassemble, it is best to let the official after-sales dismantling and repair)
Let's prepare the tools for disassembling. For disassembling this type of mobile phone with a glass back cover, a hair dryer is necessary - it is used to heat the phone, separate the back cover, etc. In addition, the crowbar , scorpion, sucker is also a must. The smashing rod is used to pick up the cable socket, the scorpion is used to pick up small parts, and the suction cup is used to suck up the back cover. If you have a 0.5mm thin teardown piece, Can be used as a tool to remove the back cover, if not, it is also possible to use a crowbar. Finally, always remember to wear anti-static gloves or anti-static bracelet.
Remove the back cover: basic operation
Before disassembling the phone, we need to remove the card tray. Note that there are two holes near the card tray, and the microphone hole is close to the USB port. Only the hole on the card tray is the ejector hole.
For the removal of the Vivo NEX glass back cover, it is necessary to first heat the glass back cover with a hair dryer. Note that in particular, the four edges must be heated, and the rounds are blown back. Remember not to blow the same position all the time. Do not blow the battery area directly.
While heating, use the suction cup to suck the corner of the phone and try to pull it up. After ten minutes of heating, the back cover of the Vivo NEX can finally be sucked up by the suction cup. However, because the back cover is made of glass, and the buckle is more Tight, can not directly use the brute force to lift the back cover, so as not to damage the battery cover, the screen and the internal components of the phone.
After sucking the back cover slightly with the suction cup, insert the crowbar into the gap between the back cover and the body, slide it along the slit to cut the double-sided tape, and then lift the back cover easily and safely. If you feel resistance Large, you can also use a 0.5mm thick, thin R film with a reverse R angle to slide a circle along the gap. However, the insertion depth can not exceed 3.5mm, to prevent damage to the internal components of the phone. This time the heating is more thorough, the two rods get two Next, the glue wire is broken, and the boot film is not used. If you are inexperienced and need to change the back cover, it is recommended to change it directly after sale.
The rear cover is opened like this. The motherboard and the tail plug are protected by a plastic protective cover. Unlike other mobile phones, the main board and the tail plug are connected by two cables. The purpose of this design is not known. I can slowly explore it after I remove it.
The Vivo NEX back cover also has a graphite heat sink to assist in heat dissipation, and the camera acts as a signal overflow area.
Demolition of the motherboard must be stable
Next, start to remove the motherboard. Vivo NEX has a plastic protective cover on the motherboard for fixing, protecting the socket and electronic components. Remove all the screws in the red circle above (there is a screw under the tamper) And put them in the original position. The specifications of these screws are not the same, so be sure to put them in the original position.
After removing all the screws, you can easily pick up the plastic cover and take it out.
Because of the rear dual-camera and lift-type front camera module, the space of the Vivo NEX motherboard is further compressed. The two sides of the motherboard also extend to the rear dual-camera and lift-type front camera module, making the most of the use. Space that can be used.
The next step is to separate the cable from the motherboard. The first step is to pick up the battery cable and power off the whole machine. Then, press the left and right buttons and the two tail cables to separate them from the motherboard.
Using a crowbar, pick up the two blue and white coaxial lines on the left side of the motherboard, and pull up a little, separate from the holder.
The black coaxial cable on the right side of the motherboard is also operated. Use the tamper to pick it up and pull it up a bit.
Using a pair of tweezers, tear a sticker on the rear camera line of the rear dual camera.
After the sticker is torn open, the bottom is the sub-photo cable interface, and you can pick it up.
The main camera jack below is also picked up.
There is also a small headphone jack cable jack under the sub camera cable, which also needs to be picked up.
There is also a sensor cable jack on the top of the motherboard, which is also picked up.
Then in this part of the lift front camera module, there is a mother screw to fix the motherboard and the lift front camera module, we need to use a flat-blade screwdriver to remove the screw.
After the daughter screw is removed, use a pair of tweezers to remove the small metal baffle that is fixed by the mother screw.
This metal baffle is fixed to protect the front camera cable jack and also fix the front camera's cable position.
Use a crowbar to pick up the front cable jack.
After all the above steps have been completed, the motherboard can be removed.
The motherboard of the Vivo NEX is quite special, and the whole looks like a 'mountain' shape. Most of the electronic components are protected by a shield, and there are very few exposed parts. The overall components and placement are very compact and highly integrated. Such a highly integrated motherboard, if it is really damaged, users can not repair it themselves, a high probability can only be repaired through the official after-sales.
Most of the back of the motherboard is covered with a shield, and there is basically no gap between the shields.
Below the back shield is some of the more important processors. The largest, phase-change silicone grease is the Qualcomm Snapdragon 845 processor and 8GB memory, using common laminate packages.
One big one small double shot
Next, let's take a look at the rear dual camera. After removing the motherboard, you can use the crowbar to pick up the rear dual camera.
The rear double camera of the vivo NEX uses a large and small design. The main camera is dual-core 12 million pixels (24 million photosensitive cells), F1.8 aperture, 4-axis optical image stabilization; sub-camera is 5 million pixels. , F2.4 aperture.
There seems to be no heat sink behind the main camera, but there is a small piece of copper heat sink on the secondary camera.
The main camera of the vivo NEX is very interesting. Its thickness and size are much larger than that of the sub-camera. Even its circuit board occupies part of the sub-photograph position.
Other gadgets
Next, we will remove the gadgets. Start with the headphone jack and lift the headphone jack directly with a smashing rod.
There is also a transparent rubber pad outside the earphone hole to prevent the inflow of water as much as possible.
Then use the tweezers to remove the sensor module.
This sensor module includes light sensor, distance sensor, etc. This sensor module is bigger than other models. It must be because it is only so large that it can get enough light, distance and other information through the screen. Although the sensor is bad. The chances are relatively small, but if this little thing fails, it is necessary to change only one whole module. This sensor module is more in-depth, you need to remove the motherboard to see it, so really want to change, people who do not have the ability to do it is recommended to find after-sales replacement.
Interestingly, the part of the screen corresponding to this sensor is transparent. Although the AMOLED screen originally had this feature, it is the first time to actually dig a hole out of the screen and put the sensor.
There is also a similar component in the place that can be removed, first remove the screw.
Then use the tweezers to clip it out.
This is very similar to a linear motor. In fact, the principle and the motor are really similar. Its function is to drive the screen vibration and simulate the corresponding sound—that is, it is the true face of the vivo NEX full-screen sound.
Disassemble the battery
Vivo NEX's battery is still very good, but because it is a battery, disassembly is still a risk, try to change the battery as much as possible. Even if you do it yourself, do not use sharp tools to charge the battery.
To disassemble the battery, first press the upper tail cable to the side, and then use a screwdriver to unscrew the 6 screws on the left and right sides to remove the whole piece. This 4000mAh large-capacity battery occupies most of the fuselage. This is one of the reasons why vivo NEX has a long battery life.
Reasons for using two tail plug cables
Next, go to the tail insert section, remove all the screws on the tail plug protection cover (there is a screw under the tamper), and then put it.
Like most mobile phones, the tail plug cover is also integrated with speakers.
Next, pick up the two tail plug cables and take them out.
Pick up the three coaxial lines of white, blue and black, then pull them up and take them out.
Be careful with this part. Only the position in the figure is the cable socket. The one that reflects above is not, don't mess.
After tearing off the sticker, pick up the screen cable. When I get here, I know why there are two tail plug cables: one is the cable for the tail plug and the motherboard communication, responsible for transmitting data and power, etc.; The station is responsible for connecting this screen cable (equivalent to the extension of the screen cable), responsible for transmitting display and touch data.
There is a screw in the lower right corner of the tail plug, to be taken out.
After removing the last screw, you can remove the tail plug by picking up the tail.
The shape of the tail plug is also irregular, and Vivo NEX really uses the space to the extreme...
Because there is no place for the card slot on the motherboard, the card slot is also set at the tail.
There is a vibration motor under the tail plug, which can be taken out directly with tweezers.
The last turn is this little thing. This little thing is the screen fingerprint module. To remove it, you need to remove the two screws first.
Then we can use the tweezers to take out the screen fingerprint module. Note that you must follow the steps. When you take it out, you must be careful. Do not insert the tweezers too deep to prevent damage to the screen fingerprint module.
The third-generation screen fingerprint technology used by Vivo NEX is completely different from the previous one. The module itself is very similar to the camera, and the previous screen fingerprint technology is something like a chip.
Like the sensor section, the Vivo NEX screen is also transparent at the screen fingerprint location.
The main event: Disassemble the lift front camera
Next, it is necessary to dismantle the most complicated lifting front camera of this mobile phone. This part of the disassembly will remove many small parts, it is really not recommended to disassemble this part.
When disassembling the front camera, first remove all the screws you saw. Remember to put them in the original position. There are several specifications for the screws here. It is very troublesome to mix.
The top stop is fixed with two sub-fuse screws and should be removed with a flat-blade screwdriver.
Then under the front camera cable, there is a stopper covered with a black sticker. Under the black sticker is a screw. After cleaning the sticker with a tweezers, remove the screw.
Then use a pair of tweezers to remove the round piece of iron.
The next step is to remove the motor module and use the tweezers to clamp the lower part to remove it.
The lower part of the motor module is the motor, and the upper part is the climbing device. The climbing device has a spiral pattern rod, a slide rail and a push module. After the motor is started, the propeller module is controlled to rotate by rotating the screw rod. The rail moves up and down, which in turn pushes the front camera up or down.
In the remaining front camera section, there is also a 'screw'. This 'screw' is not a simple screw, it is very long, and also acts as a front camera fixed rod.
After loosening with a screwdriver, slowly remove it with a pair of tweezers. This step should be careful that the spring pops up suddenly. It is best to let the little friend find something to block nearby.
This small part is very important. The push module on the motor module is to push this small component, so that the latter drives the entire camera module to lift.
I took a small gif to illustrate how this camera works. The motor rotates, the auger rotates, pushing the module up or down, which drives the entire camera module up and down. The spring acts as a buffer: when the camera is turned on, When squeezed by external force, the camera will retract into the fuselage. If there is no spring, the camera will retract inside the fuselage too fast and may receive damage.
Next, continue to disassemble the front camera. There is a small screw in this place. After removing it, use the tweezers to remove the small stopper.
Then pull the entire camera out.
The front camera uses an extra long cable to prevent it from being overly pulled during use. The entire front camera is packaged and can be replaced only for the entire replacement. So if the front camera is really damaged, It is recommended to go directly to the official after-sales service.
There is also a plastic pad under the front camera as a limiter, take out.
There is also a metal stopper on the top, which is taken out directly with tweezers.
The small parts of this lifting module (such as various limiters) are more, or that sentence: It is not recommended that the user disassemble and repair this area. If necessary, please consult the official after-sales for disassembly and repair.
Some of the last accessories
The left side of the fuselage is the volume button and the power button, you can use the tweezers to clamp the cable.
On the right side of the fuselage is the Jovi button, which is also used to clamp the cable directly with tweezers.
Display
Vivo NEX's display and middle frame are glued together, which is very difficult to disassemble in terms of disassembly difficulty. If the heating is not complete, it is easy to cause secondary damage to the display; while pressing the new screen to the middle frame On the time of the coating may also be uneven due to uneven glue, so the pressure is not stable. So in the disassembly, replacement of the display, I do not recommend that users dismantle themselves, it is best to directly find the official change. Both the screen and the middle frame are replaced together. At the same time of safety, the quality is also high.
Conclusion
From 1 pm to 5 pm, it took 3 hours to completely disassemble the flagship of vivo NEX. The integration of this phone is too high, and because of the lifting front camera, Its complexity is also higher than that of ordinary mobile phones: it uses a female screw, has various limiters, and various small parts. Not to mention ordinary users, for engineers, repairing such a mobile phone is also very One of the most laborious things. Therefore, users are advised not to disassemble this mobile phone. If necessary, it is the safest choice to find the official after-sales disassembly and repair.
However, on the other hand, Vivo NEX has such a level of sophistication and is the embodiment of innovation. In order to realize the zero-screen full screen, and the use of the lift front camera and the screen light-sensitive technology, the vivo NEX has such a Complexity. In order to achieve all these new things, Vivo must start from scratch - from scratch, it is the first step of innovation, and finally we see that all the innovations such as vivo NEX Flagship.
