Overview
What this part is
The display flex cable on the Galaxy S26 Ultra carries the picture and touch signals between the screen and the main board. It can tear during a repair, or be damaged by a drop or liquid. A damaged flex can cause a black screen, lines, flicker or touch faults even when the screen panel itself is fine.
This is a technician's part. Fitting it usually involves careful work on the display connection, so it is best suited to repair shops with micro-soldering tools. If the screen glass or panel is cracked, a full screen replacement is the better fix.
