iPhone Screen Flickering? Causes and How to Fix It (UK)

iPhone screen flickering is often software you can fix for free — but flicker that started after a drop, or comes with lines, means the display is damaged and needs replacing (from £18.66). Work through the free checks first; most flicker never needs a part.

Free fixes to try first

1. Force restart: Volume Up, Volume Down, hold Side until the Apple logo.
2. Update iOS (Settings > General > Software Update) — some flicker is a known bug fixed in updates.
3. Turn off Auto-Brightness (Settings > Accessibility > Display & Text Size) and test.
4. Reduce Transparency / Reduce Motion can stop flicker on some models.

Software or hardware?

Direct answer: if flicker survives a restart, an iOS update and toggling Auto-Brightness — or started after a drop — the display panel is failing and a replacement screen resolves it.
