How to Tell if Your iPhone Screen Needs Replacement

It can be difficult to know whether your iPhone screen just has a minor scratch or if it needs a full replacement. If you see deep cracks, dead pixels, or unresponsiveness to touch, it might be time for a professional to step in.

Common Signs

1. Touch Issues: The screen stops responding.
2. Visual Artifacts: Colored lines or black spots.
3. Deep Cracks: Glass that can cut your fingers.

If you experience these, check out our Screen Replacement Services to get it fixed.

Glass, digitizer, or LCD — which layer is broken?

An iPhone screen is three layers, and which one failed decides whether you need a repair at all and what it costs:

• Top glass only: Hairline crack, touch and image perfect. Cosmetic — you can wait, though sharp glass and dust ingress are reasons not to.
• Digitizer (touch): Glass may look fine but the screen ignores taps, or you get ghost touch (the phone tapping itself). This needs a display replacement.
• LCD/OLED panel: A green or coloured line, black blotches, flickering, or half a dead screen. The panel is gone and must be replaced.

On iPhones all three layers are fused, so any of the last two means a full display swap — there is no cheap "just the touch" fix.
