Green Line on Your iPhone Screen? Causes & How to Fix It (UK)

A green (or pink/white) vertical line on an iPhone screen almost always means the OLED panel is physically damaged — and because the fault is inside the bonded display, it can't be fixed by software or a reset. A replacement screen is the fix, from £18.66. Here's why it happens and what to do.

Why does an iPhone get a green line?

Direct answer: a green line appears when the OLED panel's internal layer or the thin ribbon connection inside it is damaged — most often after a drop, sitting on the phone, or pressure in a pocket, even if the glass didn't visibly crack. It can also appear after the display overheats or, occasionally, following a botched screen repair. Because the damage is inside the sealed panel, no software update, reset or app removes it.

Quick check: is it definitely the panel?

1. Force restart (Volume Up, Volume Down, hold Side) — rules out a one-off glitch.
2. Install the latest iOS update — to be thorough, though lines are rarely software.
3. If the line stays, spreads, or appeared after a drop, it's the panel.

Fixing it: the replacement screen

A green line is resolved by replacing the display assembly. Screens start at £18.66 (iPhone 15 incell), with OLED options such as the iPhone 13/14 Pro hard-OLED range from £50.82. Since the original iPhone panel is OLED, an OLED replacement best matches the original look — see our iPhone screen grades guide.

Why does my iPhone have a green line on the screen?

No — a restart or update is worth trying to rule out a glitch, but a true green line is inside the sealed OLED panel and needs a new display assembly.
