Samsung Galaxy phones use bright, sharp AMOLED displays. When they are damaged, the symptoms look different from a simple cracked screen. Here is what the most common faults mean.
A single vertical line, or several, usually means the display panel or its connection has been damaged, often after a drop or pressure in a pocket. These lines rarely go away on their own.
Black areas that spread over time are a sign of a damaged OLED panel. Even if the glass looks fine, the display underneath can be broken.
Flicker can sometimes come from software or brightness settings, but if it continues after a restart and update, the display is the likely cause.
Areas of the screen that do not respond, or “ghost touches”, usually mean the touch layer is damaged.
Samsung has more troubleshooting help on its UK mobile support pages.
If lines, spots or touch problems remain after these checks, the display needs replacing. Back up your phone first if you can, using our backup guide. On many Galaxy models the screen comes as one assembly with the frame, so the repair varies by model. We confirm the fault and price first.
