You pull your iPhone out of your pocket, catch it in the light, and there it is, a line across the glass. Your stomach drops. Is it just a scratch, or have you joined the cracked-screen club?
Here’s the simple answer upfront: scratches are usually cosmetic, a screen protector is often enough. Cracks are structural damage, and you’ll normally need iPhone screen repair (or a full iPhone screen replacement) sooner rather than later.
I’m James Waterston, in-house repair specialist at Repair My Crack, and I’ll talk you through how to tell the difference, what’s safe to live with, and when it’s time to get it sorted properly.
Scratches vs cracks, a quick test before you panic
A scratch is like a scuff on a windscreen, annoying, but the glass is still doing its job. A crack is like a chip that’s turned into a spiderweb, it’s a weak point that spreads.
If you’ve only got 30 seconds, do this:
- Fingernail test: if your nail catches, you’re likely dealing with a crack (or a deep gouge).
- Torch test: shine a torch at an angle. Scratches reflect sharply. Cracks tend to cast darker lines under the surface.
- Touch test: if taps don’t register, or it “ghost touches”, treat it as damage that needs repair.
Here’s a quick comparison you can save:
| What you see/feel | Most likely | Is a protector enough? | Risk if you ignore it |
|---|---|---|---|
| Fine lines only visible in bright light | Light scratches | Often, yes | Mainly cosmetic |
| Nail catches on a line | Crack or deep gouge | Usually, no | Spreads, lets moisture in |
| Black blobs, green lines, flicker | OLED/LCD damage | No | Display failure likely |
| Sharp edge on glass | Cracked glass | No | Cuts fingers, worsens fast |
One more thing people miss: sometimes it’s not the glass at all. The screen protector itself can crack and look dramatic. Peel it off carefully and check the real screen underneath.
When a screen protector is enough (and what to buy in 2026)
If the iPhone is working normally and you’re looking at surface scratches, a protector can be a perfectly sensible fix. It won’t remove existing scratches, but it can stop them getting worse, and it can mask light scuffs so they’re less obvious day to day.
In 2026, I still recommend a decent tempered-glass protector over a flimsy film. Most decent ones quote a 9H hardness rating, and the better kits include an alignment tray so you don’t end up with dust bubbles that drive you mad every time the screen lights up.
A protector is usually enough when:
- The mark is purely cosmetic, with no sharp edges.
- Touch, Face ID, and brightness are all normal.
- There’s no “ink bleed” or coloured lines.
- The phone hasn’t taken a heavy impact (even if the glass looks fine).
Pair it with a case and you’ll reduce the odds of needing cracked screen repair UK services later.

When you need iPhone screen repair (and why waiting costs more)

A crack is more than a “line on glass”. It’s a stress point. Every tap, every pocket squeeze, and every temperature change helps it creep. Once the glass is breached, dust and moisture can work their way in, and that’s when small damage turns into bigger faults.
You likely need iPhone screen repair if you notice any of these:
- The crack is spreading, or the glass feels sharp.
- Touch response is hit and miss.
- The display shows lines, flickers, or has dark patches.
- The crack sits near the edge, where pressure is highest.
