The hinge flex cable runs along the device hinge and undergoes significant mechanical stress.
Signs of failure include flickering screen, unresponsive touch on the folded area, or lines.
Replacement involves disassembling the foldable display module, replacing the flex cable, and reassembling the hinge.
Requires skilled technician with tools like P2 screwdriver, tweezers, and adhesive materials.
OEM replacement cable costs around $20–40 (500k–900k VND).
Replacement time is roughly 1–2 hours; post-repair testing of touch and display folding is essential.
DIY is not recommended without experience due to hinge complexity.
