In this article, I will disassemble a Huawei Honor 9 to remove the back cover, battery, front camera, rear camera, bottom board, speaker, and motherboard.
First, let’s take a look at the Huawei Honor 9 specifications:
5.1-inch 1080 x 1920 (428 ppi) LTPS IPS LCD capacitive touchscreen, 16M colors
HiSilicon Kirin 960 Octa-core processor (4x 2.4 GHz Cortex-A73 and 4x 1.8 GHz Cortex-A53) and Mali-G71 MP8 GPU
Dual 20MP + 12 MP, f/2.2, phase detection autofocus, 2x optical zoom, dual-LED flash
8MP, f/2.0 front camera
4GB RAM and 64GB ROM
EMUI 5.1 based on Android 7.0 Nougat
Teardown is what we do! Follow us on Facebook and Twitter for the latest repair news.
We did not find screws at the bottom of the phone. The Huawei Honor 9 uses a double-sided glass design, so the screen and back cover should be secured to the body with glue.
The bottom of the phone has a speaker grille, a 3.5mm headphone jack, and a USB Type-C port.
Heat the back cover for about 2 minutes with a hair dryer.
Open the back cover a little bit with a suction cup. Then, insert a pick under the back cover and slide it along the edge until it is opened completely.
There are only two camera holes and a flash hole on the back cover.
The Huawei Honor 9 still uses the classic three-stage design: the upper is the motherboard, the middle is the battery, and the lower is the USB-C board.
To achieve better heat dissipation, it uses a large piece of graphite thermal sticker to cover the body.
Remove all screws securing the metal plate to the motherboard.
It uses a single metal plate to secure various connectors. This metal plate is also attached to some plastic materials, and the manufacturing process is relatively complex.
We need to disconnect the battery connector first to ensure the internal hardware is not damaged.
Disconnect the front camera connector and remove the camera.
I attempted to remove the rear camera and then remove the motherboard, but I was unsuccessful because the camera was secured very tightly.
Lift and remove the motherboard.
The rear camera is secured to the body with double-sided adhesive tape, and it must be removed using a small tool to pry it slowly.
The metal shield is coated with thermal grease. The processor, RAM, and ROM should be under the metal shield.
Rear camera: Dual 20MP + 12 MP, f/2.2, dual-LED flash
Front camera: 8MP, f/2.0
According to the words on the camera module, this camera module is assembled by O-Film.
Now, let’s take a look at the bottom of the phone. The black part is the loudspeaker, which is secured by seven screws. The following should be the USB-C board.
After removing the screws, we attempted to remove the speaker but were unsuccessful. It looked very slim, so I didn’t dare to apply too much force. I had to use a hair dryer to heat it and then remove the loudspeaker smoothly.
As you can see, the speaker has three metal contacts used to connect it to the USB circuit board.
Disconnect the four connectors and the coaxial cable.
Remove the 3.5mm headphone port. As we know, the headphone jack is the most commonly used component, and it is easier to replace.
The USB-C port equipped with a rubber ring can effectively prevent water and dust from entering the device.
The Honor 9 does not use adhesive tape to secure the battery. It should use a double-sided adhesive to secure the battery to the body. If you replace the battery, you will be in more trouble. After all, removing the battery is not an easy task.

The Huawei Honor 9 does a pretty good job in terms of workmanship, and its metal frame makes the internal structure of the body very sturdy. To achieve better heat dissipation, it uses a large piece of graphite thermal paste to cover the body, and the metal shield of the SOC chip is coated with thermal grease. And details like the rubber-wrapped USB Type-C port and the 3.5mm headphone jack are also handled very well.
Each module can be replaced independently, and a large amount of double-sided tape and adhesive is used, making it difficult to replace parts.
I could never find any information about the screen protection of the Honor 9. Does it have Corning Gorilla Glass 3, 4, or 5?
From the teardown, we can not find the glass model.
From the teardown, we can not find the model of the glass.
This phone also has laser autofocus. The device behind the dark cover glass, just below the camera flash, is a chip from STMicroelectronics.
What size screws are used in the motherboard?
