The Honor 20 PRO uses a second-generation precision double-layer diaphragm process, which has two layers of Highlight and Color diaphragms under the glass. The color layer makes the product present a gradual change of color from the center to the surrounding, enriching the visual level of the product and enhancing the deep visual experience.

The glass back cover is usually glued with a double-sided glue, and the Honor 20 PRO is no exception. Before disassembly, it is necessary to use a heating device to heat the back cover, use the suction cup to open a gap and use the pick to open the back cover slowly.

Compared with several Honor mobile phones that have been disassembled before, Honor 20 PRO has more solid workmanship. The main board is covered with a protective cover to protect the motherboard from stability under extreme conditions such as dropping. The motherboard and battery are covering with the graphene heat sink. It should be emphasized that the Honor 20 PRO uses the world’s most advanced mobile phone cooling technology – graphene heat dissipation, compared to the Honor 10, the heat dissipation performance increased by 23%.

Use a Phillips screwdriver to remove the screws in the red circle above and slowly pry open the protective cover from the lower left corner.

In this picture, we mark the distribution of each module, including the light distance sensor, earpiece, camera, flash, fingerprint cable, noise reduction MIX, motherboard cable, RF coaxial cable, battery cable, and display cable.

The most prominent feature of Honor 20 PRO is the rear four cameras, which account for almost a third of the top of the fuselage. Because the Honor 20 series adopts side fingerprint module, compared with the rear fingerprint module, the integrity of the back cover of the mobile phone is maintained, and the whole body is more beautiful. Hold the phone with one hand, and the thumb just unlocks the phone. The recognition speed and accuracy are higher than the in-screen fingerprint module.

To achieve a higher screen ratio, we placed the light and distance sensor on the top of the fuselage, which looks a bit like an infrared port. His functions are twofold: 1. Pocket anti-mistakenly touch function. 2. During the call, the automatic screen will be judged, and the mobile phone will be close to the face, and the automatic screen will be opened.
