In dismantling the intelligent speakers has HomePod, after Samsung Galaxy S9 and 2018 models iPad, well-known institutions iFixit disassembled again "claws" stretch back with "three Leica camera," Huawei P20 Pro.
Yes, Huawei P20 Pro is undoubtedly one of the recent hot star models, both with either "Liu children" but also with the appearance of the Home key, back or gradient color and "three Leica camera" designs, are so many Huawei people this year P series flagship impressive.
Among them, the back of the set by a 40 million-pixel main camera led "three Leica camera" lens, even more so Huawei P20 Pro became the first on DxOMark list. Therefore, it may be a lot of people want to know, on this camera design bold new phone, its internal structure in the end what excels.
Below, we will hold with the perspective of iFixit, in-depth look at this flagship.
Huawei P20 Pro Basic configuration:
Screen: 6.1 inches OLED full screen
Core: Hass Kirin 970
Memory on: 6GB
Storage: 64GB / 128GB / 256GB
Front: 24 million pixels (F / 2.0)
Post: 40 million pixels (main camera, F / 1.8) / 2000 million pixels (black and white, F / 1.6) / 800 megapixels (telephoto, F / 2.4)
Battery: 4000mAh
System: EMUI 8.1 (Android-based 8.1 Oreo)
Other: IP67 waterproof and dustproof / face recognition / fingerprint / Super Charge fast charge
Back camera 3, there are even OIS
Although Huawei P20 Pro is a support IP67 protection cell phone, but that did not make the whole process of dismantling tricky. Instead, iFixit team also eliminates the need for heating the open end of the previous process, only a sucker tool and easy to paddle a scratch, it opened a P20 Pro back cover.
In unscrew the screws and push cable, open and back, we see that piece would have to be equipped with a "three Leica camera," and the flash circuit board. Can be seen, the three rear camera and flash is designed as a module, arranged to be fairly compact.
Although this is a "three Leica camera" lens module, but Huawei only for its design of two cables, 40 million-pixel main camera and a black and white camera 20 million pixels share one cable, while the other sinking 8 million pixel telephoto camera is another exclusive cable.

Among them, sinking 40 million pixel primary camera using a 1 / 1.7 inch sensor, it X than the iPhone 1 / 2.9 Yingcun sensor and Samsung Galaxy S9 + 1 / 2.55 inches of the sensor even larger, its highest ISO can reach 102400.
More importantly, after the dismantling of iFixit found by either sinking 40 million pixel color camera, or sinking, looks "most flat" black and white camera, they all have OIS optical image stabilization feature.

In other words, three back of the camera at the hardware level seems to have been equipped with OIS optical image stabilization feature.
Obviously, this is before Huawei declared only 800 million pixel camera equipped with a telephoto OIS optical image stabilization, the other two cameras based on artificial intelligence AI chip image stabilization say, there is a certain discrepancy in the conference.
But Huawei did not comment, we are not clear how this three camera with optical image stabilization function is working.
In fact, in addition to the three cameras with optical image stabilization, iFixit also noted that a detail of the circuit board carrying the camera module is also connected with a rear cover for the laser focus sensor, so that implemented Huawei P20 Pro fast focus.
The modular component design, as well as high-capacity battery
Throughout the process of dismantling, the internal Huawei P20 Pro those modular component design, but also people left a deep impression.
For example, the above-described camera module and a carrier board thereof, Kirin motherboard 970 is mounted a small, vibration motor and a charging interface Type-C are modular design. The advantage is that these parts once damaged, repaired easily achieved by simply replacing.
We first focus briefly on a small piece of the motherboard, which incorporates the above core Kirin 970, important parts Micron memory on 6GB LPDDR4 Samsung 128 GB flash memory, NXP's NFC controller.
The following is a list of specific components on the motherboard:
Micron 6 GB LPDDR4 SDRAM package Kirin (Kirin) 970 chips
Samsung KLUDG4U1EA-B0C1 128 GB V-NAND flash memory
Hass Hi6403-GWCV110 Audio IC
TI BQ25895 I2C charge control module
NXP 55102 PN548 NFC controller
Hass Hi6363-GFCV100 RF transceiver module
Skyworks 78113-14,78114-61 the LTE module and the front end 78117-4A Skyone
Hass Hi6421-GFCV810 Power Management IC
Cypress BCM43596 Wi-Fi and Bluetooth module
Hass Hi6423-GWCV100 Power Management IC
Huawei P20 Pro except for the part modular parts easy to replace, compared to the majority of mobile phone battery is also easier to disassemble it.
In the process of dismantling, iFixit found Huawei P20 Pro battery does not use a lot of strong adhesive glue is fixed, thus removing the battery does not need the use of hot air heating, using only enough peptizer, the battery can easily out.
Speaking, this battery before specification Huawei Mate 10 Pro closer piece battery, the rated working voltage of 3.82 V, has a 4000 mAh (corresponding to 15.28 Wh) of the battery capacity.
This battery specifications, far more than the S9 + 13.48 Wh 10.35 Wh parameters and iPhone X Samsung Galaxy, to enhance the mobile life, it will certainly help.
Huawei P20 Pro harder to repair than the iPhone X
Although Huawei P20 Pro application on the internal modular design some parts, replacement parts relatively easy, but the iFixit team continues to believe that Huawei P20 Pro in poor repair, and give it shot a 4-point "may maintainability" Rating (out of 10, with higher scores indicating more easy maintenance).
This score with Samsung Galaxy S9 / S9 + equivalent, but less than 6 minutes iPhone X made. In iFixit view, Huawei P20 Pro demerit points deducted points largely on the dismantling of the screen.
To disassemble P20 Pro screen, iFixit need to use a pillow iOpener heated portion of the screen is heated, so that the glue between the screen and the frame to be melted.
Be
Of course, this is just a challenge when replacing the screen assembly external screen if it is broke, then disassemble them even more trouble, you still need a way to separate the heating of the internal display and external screen. And this separation operation, likely to cause damage to the glass panels.
Because of this, the problem only when you need to replace the proximity sensor, light sensor, front camera and when the handset also need to capture screen assembly, disassembly encountered.
In addition, although the back of the glass cover is easy to remove, but such materials also increases the possibility of damage to the back cover.
Overall, iFixit considered repairable Huawei P20 Pro poor, from the maintenance point of view, the advantages of Huawei P20 Pro are:
Many parts of a modular design for easy replacement of independence
Replacing the battery is not too difficult, is the need to spend some time and effort
The disadvantage is that:
Before and after the mobile phone design glass, so the risk of breakage when removing larger
When replacing the screen, at least twice against strong glue, not easy to split up to search for information networks love board plus interest, daily new development board, intelligent hardware, open source hardware, and other activities you can single-handedly make a full grasp.
