As we all know, Huawei officially launched the Huawei Nova 3 last month. The phone features a 6.3-inch full screen and is powered by AI Kirin 970 processor. With a variety of vivid color options and brilliant picture-taking effects, this phone undoubtedly receives much popularity among young people. Today, we will start the teardown of the Huawei Nova 3 to explore its internal structure.
First of all, power off the phone. Then, remove the SIM card tray. Now, separate the back cover from the phone body with a sucker. Use a clip to widen the gap when the gap appears between the back cover and the phone body. During the process, I need to carefully deal with the 3D glass back cover and the fingerprint reader cable. After uncovering the back cover, I found that cable ports are fixed by a cover plate. The smartphone has a stable internal structure design. Therefore, it is not easy for the cables inside to get disconnected. Remove the cover plate before disconnecting the cable.
After disconnecting the fingerprint reader cable, the back cover was successfully removed. The glues were applied to the verges of the back cover, which indicates that the smartphone has excellent sealing performance. Besides, many graphite stickers and foam were found on the back cover.
The phone has a 24MP and 2MP dual colorful camera setup on the front, with an F/2.0 aperture. The colorful camera deals with image color, while the black-and-white camera is in charge of image detail. This allows for enhanced image layering.
It features a 16MP colorful and a 24MP black-and-white dual-rear camera with dual F/1.8 aperture. The dual rear camera setup can intelligently recognize different scenes through AI learning.
Removing metal shield cover and erasing yellow thermal grease. According to the SEC mark, it can be inferred that the part circled red is a 6GB K3UH6H6 memory chip from Samsung, the component below it is the Kirin 970 chip, the part circled blue is the Toshiba flash, and the part circled green is HI1102, which integrates Bluetooth function. The smartphone has high space utilization on the back of the motherboard with regard to its price, which provides space for the battery with a large capacity. The component circled red is HI6421, which is in charge of the power management of the processor. As for the part circled blue, it is the HI6403 audio chip.
Now, we will start to remove the vice board. Take out the screws, and then remove the speaker module with a pry tool. According to the GETTOP label on the speaker, we know that the speaker that the Nova 3 comes with is made by Gettop Acoustic company.
A layer of waterproof rubber is placed on the surface of the charging port and the earphone port on the vice board. The battery is removed. It is made by Desay. Its typical capacity is 3750mAh, and its rated voltage is 3.82V. The four edges of the smartphone are thickened to better protect the phone from being dropped. These are all the parts of the phone.
Summary
As a mid-range smartphone designed for young people, the Huawei Nova 3 uses good-quality material. However, the 3D glass case makes it risky to remove the back cover from the phone body. The thin fingerprint cable is much more likely to get broken if you have no idea where it is placed. It is also difficult to remove the battery. Therefore, I don’t recommend doing the teardown by yourself.
