In PBKreviews disassembly video of the Poco F4 5G, the reviewer gave it a 5.5/10 for repairability. The design of the device is not well designed with repairability in mind. While it’s not impossible to do a screen replacement, the flex cable does need to be routed through the center frame – that is before any glue is applied.
Opening the phone is like any other: heat the back panel and pry around the perimeter to break the glue. The panel comes off without any snafus and the camera glass seems to fix as a separate piece from the back cover by breaking the glue and replacing it.

After removing 17 screws and removing the top shield fitted with antenna lines and graphite for heat transfer, the battery can be disconnected and other components can be disconnected. The front camera is glued in place and once the motherboard comes out, the camera modules can be easily flipped out and swapped out. The back of the motherboard features copper and graphite for thermal transfer.
The battery’s large and strong pull tabs make it easy to remove the 4,500 mAh battery. Removing the battery reveals a few more flexible cables running from the main board to the sub board. The battery must be removed to remove the charging port, SIM tray, and power button flexible cables.
