As we all know, Huawei officially launched the Huawei Nova 3 last month. The phone features a 6.3-inch screen and is powered by an AI Kirin 970 processor. With a wide range of vibrant color options and excellent photography capabilities, this phone is undoubtedly very popular among young people. Today, we will take apart the Huawei Nova 3 to explore its internal structure.
First, turn off the phone. Then, remove the SIM card tray. Now, use a suction cup to separate the back cover from the phone body. When a gap appears between the back cover and the body, use a pick to widen the gap. Be careful when handling the 3D glass back cover and the fingerprint sensor flex cable. After removing the back cover, I found that the flex cable connector is secured by a metal plate. This smartphone features a sturdy internal design, making its internal flex cables difficult to disconnect. I need to remove the metal plate first before disconnecting the flex cable.
After disconnecting the fingerprint reader cable, the back cover was successfully removed. The glue was applied to the edges of the back cover, indicating that the smartphone has excellent sealing performance. In addition, a large number of graphite sheets and foam materials were found on the back cover.
The phone has a 24MP and 2MP dual camera setup on the front, both with an F/2.0 aperture. The color lens handles image color processing, while the monochrome lens focuses on capturing image details, enabling richer image layering.
It features a 16MP colorful lens and a 24MP monochrome lens on the back, both with a dual F/1.8 aperture. The dual rear camera setup can intelligently recognize different scenes through AI learning technology.
Remove the metal shields and wipe off the yellow thermal grease. According to the SEC mark, the part in the red circle is a Samsung 6GB K3UH6H6 memory chip, below which is the Kirin 970 chip; the part in the blue circle is Toshiba flash memory; and the part in the green circle is the HI1102 chip with integrated Bluetooth functionality. The back of this motherboard has a very high space utilization, leaving ample space for a large-capacity battery. The component circled in red is the HI6421 chip responsible for processor power management, while the one circled in blue is the HI6403 audio chip.
Now, we will begin removing the sub-board. First, remove the screws, then use a pry tool to take out the speaker module. According to the label on the speaker, the speaker is manufactured by Gettop Acoustic.
Both the charging port and headphone jack have a waterproof rubber ring. After removing the battery, we found it was manufactured by Desay, with a typical capacity of 3750 mAh and a rated voltage of 3.82V. The four edges of the smartphone are reinforced to enhance drop resistance.
Summary
As a mid-range smartphone designed for young people, the Huawei Nova 3 is made of high-quality materials. However, the 3D glass body makes it risky to remove the back cover. The fingerprint cable is much more likely to break if you have no idea where it is. Additionally, the battery is also difficult to remove. Therefore, it is not recommended to disassemble this device yourself.
