Back side of the motherboard. In addition to the 13 million pixel main lenses and motherboard shields, the rest are not removable. The solder joints of the entire motherboard are very fine, and the layout of the parts is also very working, so the heat dissipation effect of the entire motherboard is still good.
The front view of the motherboard is the extra large-area shield, which effectively prevents electromagnetic interference between the components, and plays a protective role. From this, two cameras can be removed directly.
Synaptics S3202B Touch Management Chip, the user's touch operation on the screen is responsible for this chip.
Remove the motherboard behind the camera.
