First of all, remove the SIM card tray from the bottom of the phone. The surface of the SIM card tray uses plastic material, and its interior part is made of metal. In this way, the card can be both flexible and hard. Besides, the card tray is designed with the rubber ring which is used to prevent vapor from entering.
No screw is placed at the bottom of the phone body. Therefore, we first heat up the back cover to make the glue less sticky. And then, use a sucker to remove the back cover. As a result, the screen is removed instead of the back cover, which surprises me a lot. After taking out the screen, we find no screw inside.
After removing the back cover, we can see that the phone inside adopts a three-stage design. As the SIM card tray is placed at the bottom of the phone, the bottom part occupies much space. The motherboard on the top is covered by a large plate. Although the camera is eye-catching, I still decide to take out the motherboard first and to figure out its structure. Therefore, I first disconnect the cable of the battery. And then, disconnect the cables of the button nearby and the vice board at the bottom.
The shield cover on the front of the motherboard is covered with a layer of copper foil which can help heat dissipation. After uncovering the copper foil, several bare small components can be seen. However, the big shield cover can’t be removed. After removing the shields on the surface, the Samsung K3UH7H7 8GB LPDDR4 memory chip can be seen in the middle. The Qualcomm Snapdragon 845 mobile platform is below the memory chip. The flash is hidden in a shield near memory chip, so we can’t see it. This is the vice camera. This camera supports four-axis optical image stabilization function.
The component which looks like a linear vibrator is the phone’s earphone. Vivo claims that this component is a key to make the screen make a sound. From that, we can see that it is totally different from piezoelectric ceramics acoustic that the Xiaomi MI MIX. However, their acoustic principle is the same.
From the seal cover, we can infer that the cost of this vibrator unit is high. The vibrator makes it possible for the user to hear clear sound when close to the screen even no aperture is designed on the earphone. Besides, compared with piezoelectric ceramics acoustic, this design can bring more excellent sound.
The battery is fixed in a different way. The battery is fixed on the metal base, and the base is fixed by six screws. So I need to take out six screws first before removing the battery. When I first see the package of battery, I have thought that its supplier is Sony because I have seen similar package before when tearing down the Sony XZ2. The Vivo NEX sports a super large 4000mAh battery with the capacity of 15.4Wh and it supports 22.5W flash charge technology. From the back of the battery, we can see that its supplier is ALT.
