For ZTE, which is brave in innovation, and cooperation with multiple different processor manufacturers is not new. In addition to the association and Qualcomm cooperation, it has recently been teamed up with Intel to build an Intel Inside mobile phone --geek v975. Today, with the advent of U988S, the name of the first Tegra 4 mobile phone will also be blooming.
As the first Cortex-A15 architecture of the world, the biggest highlight of the Tweida TEGRA 4 is its up to 72 core GPUs, which is six times the last generation of TEGRA 3, video and game performance greatly increase. Plus its unique power saving chip, the battery life has also been enhanced. I believe that many people have a question, as the world's first Tegra 4 mobile phone, what is the internal structure of ZTE U988S? Let us notice the answer together.
According to the practice, we still have to look at this phone well before disassembling the machine. From the shape, ZTE U988S's overall appearance continues the design of ZTE Geek, although the screen is still 5 inch IPS screen, but the resolution has been upgraded to 1080P level (1920 × 1080 pixels), and the OGS full bonding technology, light transmission Better. Also, it is worth mentioning that its side buttons are all concentrated on the right side of the whole machine, which is very beneficial to handle the right hand.
Although the screen uses a 5-inch large screen, ZTE U988S is also taking into account a single hand control, and its 9 mm slim body plus the big returning design behind it has increased the comfort of the machine, plus The Mifavor UI is optimized for the interface of one-handed manipulation, and it is natural to use it. This time, ZTE U988S also promoted the camera to 13 million pixels and joined advanced camera functions such as rapid photo, and it was not easy to use. Ok, after the introduction of the basic information of this mobile phone, we will officially begin the disassembly of ZTE U988S.
Since ZTE U988S is designed with the rear cover, it is not very difficult to dismantle it. After opening the rear cover, ZTE U988S middle shell, nine cross-shaped screws clearly, our disassembly starts from the nine screws.
The power supply is cut off before the disassembly is a basic common sense. First we ensure that the battery is removed after the phone is turned off. In this case, although the processor has changed the processor, the battery capacity has not changed, and the 2300mAh capacity battery can only be moderately biased in the current smartphone, but it uses the replaceable battery design if you have 2 After blocking or even more standby batteries, it is natural to solve the problem of life.
ZTE U988S uses a 2300mAh capacity, a 3.8V voltage lithium-ion battery.
After removing the battery, we can see the overall layout of ZTE U988S. From the basic structure, it is very small in ZTE Geek, the standard SIM card slot and the mirco SD card slot is exactly the same, then inside What is constructed? Let us continue to see it.
And now it is generally used in the star screws, this time ZTE U988S uses a more common cross-shaped screw, which also reduces the difficulty of the disassembly, and the cross-screw knife that can be seen everywhere can easily complete the job. However, the author does not recommend that everyone will disassemble, after all, involve some warranty policy issues, and the problem that the private demolition does not have to go out here.
After all of which are screwed all this nine screws, we can open ZTE U988S along the edge of the middle-shell, but it is necessary to pay attention, and the middle shell part of the three buttons on the right is adhesive, everyone is taken When the lower middle shell, you should unveiled the film to make the housing in case of preventive force.
The first appearance of the unveiled middle shell and the U988S motherboard.

ZTE U988S speaker is at the bottom of the middle shell.
Perhaps, in order to cater to the current mainstream design, ZTE U988S motherboard is also combined with the L-motherboard plus the bottom plate, which makes the phone easier.
Detail of the top of the L-top U988S. It can be said that the core of this mobile phone is fully concentrated on the top of the L-motherboard, just as we see, whether the front and rear cameras are still centralized here, the power button and the volume control key are also top of the L-top The left side.
Compared to the L-plate motherboard, the bottom of the small board function is very simple. In addition to the vibration motor on the left, it is also responsible for connecting the camera shutter button.
This root is ZTE U988S RF line, which can not only enhance mobile phone signals, but it is one of the links to these two motherboards.
The next thing we have to do is to remove the two motherboards. First we first remove all the cables connected to the motherboard and the screen panel and the modules that can be removed.
Here is the cable connected to the screen panel and the cable connecting the bottom small board, letting them get them. It is worth noting that the cable here is a buckle that needs to pull the connection point on the motherboard to remove, cut the pain.
Here is the power button, the volume button, the screen cable, like the cable, and the drawing of the snaps can remove the cable. The two button units are bonded together on the side of the screen panel, and the viscosity is relatively strong, and what we need is to separate them carefully.
It is worth noting that there is a screw connection between ZTE's U988S's L-top M motherboard and screen panel. We need to unscrew a screw to remove the motherboard.
The picture shows the front view of the L-plate motherboard (that is, we have not removed the visible side).
The figure shows the rear view of the L-plate motherboard.
At the bottom of the L-top, it is the mirco USB interface of ZTE U988S.

After removing the motherboard, we can remove the modules that cannot be removed from the next, such as front and rear camera modules, flash modules, and more. Figure 2 million pixel front lens and 13 megapixel rear shot.
The figure shows the flash and light / distance sensor module, which is connected to the motherboard, and remove the screws when removing the module.
When the first eye saw the back of the motherboard, it was attracted by this chip. It didn't do the metal shield, which is the most protracted protagonist of today - 1.8GHz Yingda Tegra 4 quad-core processor.
Unlike general mobile phone design, ZTE U988S processor chip is directly designed outside, rather than hiding under memory chips, this is also a breakthrough. As for this chip, the author is also introduced in the previous article (click to view), interested friends can refer to it.
Just now, in addition to the CPU chip, the other chips of ZTE U988S are covered by the metal shield, and our work is to remove all the metal shield.

ZTE U988S whole machine has a total of 11 screws, including two of the right sides, respectively, respectively, and the nine screws on the left are the 9 cross-shaped screws on the middle shell.
ZTE U988S disassembles the whole family blessing. If you want to evaluate a reasonable level of repair, the author believes that ZTE U988S repair level is 8 (top 10 is the easiest, level 1 is the hardest), which is a relatively easy maintenance, but for some details Still tender, after all, there will be some places, will still be accidentally damaged.
Summary: Compared to past disassembly, this disassembly did not spend too long, the reason is that the overall composition of ZTE U988S is much like a lot of GEEK, and many places are common, so dismantled nature. Light car ripe. However, it is impressive that this all expecting Ying Weida TEGRA 4 quadrupler is independently designed, and there is no metal shield, such a design is as specifically for disassembling evaluation.
Founded around TEGRA 4 CPU, FHD Ultra HD 5-inch screen, 13 megapixel new rapid photo function, the rear lens, etc., to force hardware will also play their own strength, and will even play long . So what is the performance of this to force? Only time tells us the most exact answer.
