What Happens If You Keep Using a Cracked Screen?

It Might Look Harmless — But It’s Not

A cracked screen might start as a small chip or hairline line across the corner.

You tell yourself, “It still works fine — I’ll fix it later.”

The truth? That tiny crack is only the beginning, and waiting can make things far worse (and more expensive) down the line.

The Crack Keeps Spreading

Glass doesn’t stop cracking once it’s weakened — every tap, press, or even a bit of pocket pressure can make it worse.

Before long, that small corner chip becomes a web of fractures across your screen, making it harder to read, swipe, or type.

Once the damage reaches the internal display, you’re not just replacing glass — you’re paying for a full screen assembly.

Touch Problems and Ghost Taps

Cracks can interfere with the touchscreen’s electrical signals, leading to ghost touches (when your phone taps itself), lag, or areas that stop responding entirely.

You’ll notice it most when typing, swiping photos, or unlocking your device — all little frustrations that add up fast.

Moisture and Dust Sneak In

Those tiny cracks are open doors for moisture, dust, and oils from your fingers.

Once inside, they can corrode connectors, short out circuits, and even damage your battery.

A single drop of water or a humid day can cause problems that go far beyond the screen itself.

Glass Splinters and Safety Risks

It’s not just bad for your phone — it’s bad for your fingers.

Cracked glass can splinter or flake off with normal use, especially around the edges.

We’ve seen plenty of Christchurch locals with tiny cuts from phones they’ve “been meaning to fix for ages.”

Camera and Display Issues

Cracks scatter light and can distort colours, brightness, and clarity.

If the damage spreads near the selfie camera or sensors, it can affect photo quality and Face ID or fingerprint recognition.

Resale Value Drops Fast

When it’s time to upgrade, a cracked screen can knock hundreds off your phone’s resale or trade-in value.

Replacing the screen early keeps your phone’s value intact — and makes it far easier to sell later.

Why Waiting Costs More

A small crack repaired early might cost less than $100.

Wait too long, and you could end up paying double for a full display replacement or motherboard cleaning if moisture gets in.

In short: fixing it now protects both your phone and your wallet.
