In PBK Reviews Disassembly video of the Poco F4 5G, the reviewer assigned it a score of 5.5 / 10 for repairability. The device design is not well designed with repairability in mind. While it is not impossible to perform a screen replacement, it is still necessary to run the flex cable through the midframe before applying the adhesive.
Opening the phone is very similar to any other – heat the back panel and pry around the perimeter to break the adhesive. The panel peels off smoothly and the camera glass looks repairable as a separate piece from the back cover by breaking the adhesive and replacing it.
Little F4 5G
After removing 17 screws and removing the top shield equipped with antenna lines and graphite for heat transfer, you can disconnect the battery and disconnect other components. The front camera is glued in place and once the motherboard comes out, the camera modules can be easily pulled out and swapped. The back of the motherboard is equipped with copper and graphite for thermal transfer.
Large, sturdy battery pull tabs make it easy to remove the 4,500mAh battery. Removing the battery exposes another pair of flex cables that run from the main board to the daughter board. The battery must be removed to remove the charging port, SIM tray, and power button flex cables.
