Vivo NEX Dual Screen version dismantling – Step-by-step Guide

The heterogeneous structure in the positive and negative dual screen, vivo NEX dual screen version dismantling

Advances in technology have made the internal design of mobile phones more complicated. Recalling the internal structure of the mobile phone 6 or 7 years ago, and the internal structure of the mobile phone, it is a subterranean sky. The vivo NEX, which was demolished some time ago, is the most difficult mobile phone have dismantled before this year. Today, this throne will change hands and belong to the vivo NEX dual-screen version. Now, let’s take a look at the double-screen version of the vivo NEX dual-screen version, which will hinder my disassembly!

Let’s first look at the front and back photos of a wave of mobile phones. Vivo NEX dual-screen version uses a unique dual-screen design, each with a screen on the front and back, the front screen is 6.39 inches, 2340 x 1080 resolution, the screen ratio is as high as 91.63%. The second-generation zero-screen full-screen design makes the visual impact of the NEX dual-screen version even more shocking.

As for the secondary screen placed on the back, it is 5.49 inches, 1920 x 1080 resolution. This screen can be used as a normal display and use screen, and can also be used when taking photos and games. In addition, the three camera modules above the secondary screen and the star ring soft light occupy a certain amount of space. It is also because of the design of two screen + super multi-camera, it can be expected that the double-screen version of vivo NEX is definitely not easy to dismantle.

From left to right, they are: Phillips screwdriver, six-star screwdriver, crowbar, brooch, thin disassemble, disassemble, card, suction cup, anti-static bracelet and hair dryer. Before starting dismantling, it is risky to disassemble the machine. If you are not comfortable with your own technology, the mobile phone has a problem suggestion or let the official repair directly.

The first step: disassemble the back cover (sub-screen)

This step is mainly to disassemble the back cover, and because there is a sub-screen on the back cover, so… you said that it is not impossible to disassemble the sub-screen…

Shut down the phone as usual before disassembling, then use the card holder attached to the phone to remove the card tray located under the phone. It should be noted that do not use other tools to insert the card hole to prevent the card hole from being damaged and the card tray cannot be removed.

The Vivo NEX dual-screen version has two six-star screws on both sides of the charging port. Use a six-star screwdriver to remove the two screws.

After removing the screws, use the disassembling piece to insert into the gap between the main screen and the middle frame from the corners of the main screen and the SIM card holder. After inserting into the gap, slide it slightly and push the middle frame (back cover) a little.

After opening the back cover a little, insert the disassembled piece a little more and slide it toward the upper side and the other side of the bottom (as in the direction of the arrow).

After a few snaps are opened, the back cover and the main screen complete the first step of separation, and the back cover and the main screen can be slightly opened at 90°. However, at this time, the opening and closing angle of the back cover cannot be too large or lifted too high, because the rear cover and the main screen also have a cable connection, which is too high to easily break the cable.

In addition, the disassembly platform must be clean and free of foreign objects and particles. In addition, the strength of the disassembly should not be too large, otherwise the back cover and the phone body may be deformed, and even the screen may be broken. Do not scratch the side button switch and the position of the card holder. The former is easy to scratch and the latter is easily deformed.

Turn the back cover upside down and start working on the cable. First use the Phillips screw to remove the screws as shown and place them in order.

Then push the bracket in the direction of the arrow.

Next, use the crowbar to lift and disconnect the cable battery cable, button cable, sub-screen cable, and flash cable identified in the figure. Other cables do not need to be disconnected temporarily. Note that the battery cable needs to be disconnected preferentially.

After disconnecting all the wires, the back cover and the main screen can be completely separated.

Step 2: Disassemble the battery

The Vivo NEX dual-screen version of the battery is still using the quick-release design of vivo, which can disassemble the battery more quickly. There are several main steps in disassembling the battery. First, pull up the F-layer film and press the film to the other side to be completely separated from the battery.

Then use one hand to hold down the F-layer film and the body, and the other hand lifts the handle slightly with an angle of 30°-45°. Pull up the battery slowly after lifting the handle, taking care not to overspeed.

Another point is that disassembling the battery is risky and must be slow to do it yourself. Remember not to use a sharp and metal tool to rub the battery. If there are conditions, it is best to go to the official after-sales replacement.

The third step: dismantling the motherboard

It can be said that the vivo NEX dual-screen version is one of the most difficult mobile phones. The unique dual-screen and star-ring soft light design makes it have more cables inside. Moreover, the internal structure of the NEX dual-screen version is more complicated than that of an ordinary mobile phone, and the difficulty of disassembling the two screens is much higher than that of a single screen. So not a professional, don’t disassemble this phone. On the one hand, dismantling may result in loss of warranty service; on the other hand, improper disassembly may damage the phone. Therefore, if necessary, it is recommended to go to the official after-sales service to find a professional to dismantle. In particular, if you need to replace the screen or battery, you can find it directly after the sale and save trouble.
