Cracked Screen Protector? Here's Exactly What to Do
Posted by MIKE R.
Updated August 2026
You dropped your phone, picked it up, and there it is: a spiderweb across the glass. First, take a breath and look closely, because there is a good chance the crack is only in the protector, and if so, the protector just did precisely what you bought it for. It absorbed the hit so your display did not have to.
Here is exactly what to do next, in order: confirm what actually cracked, decide whether to remove the protector now, get the broken one off safely, check whether a warranty covers your replacement, and put a new one on properly.
Step 1: figure out what actually cracked
Protector cracks and screen cracks look similar at a glance. Three quick checks tell them apart:
- Run a fingernail across the crack. If you can feel the crack on the outermost surface, it is at least in the protector. Protector cracks are the ones you can catch a nail on.
- Look at the edges. A protector is a separate sheet with a visible border sitting slightly inside or at the edge of the display. If cracks stop at that border, they are in the protector. Cracks that run past the protector's edge onto uncovered glass are in the phone.
- Check the display itself. Turn the screen on with a bright solid background. Dead pixels, dark blotches, colored lines, or touch that stops responding in an area point to display damage underneath. A cracked protector alone never causes lines or dead zones.
If the display itself is damaged, a protector cannot fix it and this article can only help you protect the repaired screen afterward. If it is just the protector, carry on. You are out the cost of a protector instead of a display repair, which is the whole economic argument for using one.
Step 2: decide whether to remove it right away
A lightly cracked protector, one clean line or a small corner chip, can stay on for a few days until a replacement arrives. It still offers scratch coverage, and quality tempered protectors hold together well because the adhesive layer keeps fragments in place.
Remove it promptly, though, if any of these apply: the cracks are spreading, glass feels rough or flaky under your finger, edges or fragments are lifting, or the cracked area sits where you swipe constantly. Loose glass fragments can be sharp, and a badly shattered protector can shed slivers. Do not keep running your thumb over a shattered area.
Step 3: remove the cracked protector safely
- Power off the phone. Easier to see, and no accidental taps.
- Tape over the shattered area. Lay clear packing tape across the cracks. The tape holds fragments together so the protector comes off as one sheet rather than in pieces. This is the step people skip and regret.
- Warm it if needed. A hair dryer on low, kept moving six inches away for 15 to 30 seconds, softens the adhesive. Warm, never hot.
- Lift from an intact corner. Slide a plastic card, guitar pick, or a loop of dental floss under the most undamaged corner. Never use metal tools; a slipped knife scratches displays. Floss is the best choice on badly cracked glass because it cuts the adhesive without prying against broken areas.
- Peel low and slow. Keep the protector at a shallow angle and work steadily across. If a section breaks away, tape it and lift it separately.
- Clean up. Wipe the phone and your work surface with a damp cloth to pick up any invisible slivers, and remove any adhesive residue with a dab of tape followed by a barely damp microfiber cloth.
Step 4: check your warranty before buying anything
Depending on the brand, your replacement might cost you very little.
Zagg InvisibleShield protectors are backed by Zagg's limited lifetime warranty. If you registered your protector with Zagg, you can request a replacement for a damaged one through their warranty process; you typically cover shipping and handling rather than the full product price. The details, registration requirements, and current terms live on Zagg's site, and it is worth registering every InvisibleShield you buy the day you install it so the option is there when you need it.
BodyGuardz has offered its own replacement programs for registered products; check the terms that apply to your specific protector on their site.
Two honest notes. Warranty replacements come from the manufacturer under their rules, not from us, and terms can change, so always confirm current requirements with the brand. And factor in the wait: a warranty replacement takes shipping time, so many people keep a spare protector on hand and use the warranty to restock the spare.
Step 5: choose and install the replacement
Replacing like-for-like is the simple path if you were happy with the old protector. If you were not, this is the moment to switch: to a different glass line, to a matte or privacy finish, or between brands. Our BodyGuardz vs Zagg comparison and our 2026 InvisibleShield guide cover the tradeoffs, and Samsung owners can start with our Galaxy screen protector guide.
Because we sell brand overstock at liquidation prices, this is also where a multi-pack earns its keep. A pack of two or three quality protectors from our shelves often costs less than a single one at regular retail, which turns every future crack from a purchase decision into a two-minute swap.
| Situation | Sensible move |
|---|---|
| One clean crack, replacement ordered | Leave it on until the new one arrives |
| Shattered, flaking, or lifting | Tape, remove now, go bare briefly if you must |
| Registered Zagg protector | File a warranty claim, pay shipping, restock your spare |
| No warranty registration | Buy a multi-pack this time and register the new one |
| Display damaged underneath | Repair the screen first, then protect the new screen |
Install it right this time
Most protector failures at the edges trace back to installation. Clean the bare screen with the supplied wipe or a barely damp microfiber, dry with a lint-free cloth, pull remaining dust with the dust sticker or a strip of tape, and lay the protector down aligned before pressing the center and letting adhesion spread outward. Dust is the enemy; a steamy bathroom is the best dust-free room in most homes.
Frequently asked questions
How do I know if the crack is in the protector or the screen?
Feel it with a fingernail and follow where the crack lines go. Cracks you can catch a nail on, that stop at the protector's border, are in the protector. Display lines, dead pixels, dark blotches, or unresponsive touch mean the screen underneath is damaged.
Can I fix a cracked screen protector?
No, and it is not worth trying. Tempered glass cannot be repaired once cracked, and its protective strength is already spent along the crack lines. The fix is replacement, which is the design intent: the protector breaks so the screen does not.
Is it OK to keep using a cracked screen protector?
Briefly, if the damage is a single stable crack and nothing is lifting or flaking. Replace it promptly once cracks spread or the surface feels rough. A shattered protector can shed sharp fragments and no longer offers reliable impact protection.
Does Zagg really replace cracked InvisibleShields for free?
Zagg's limited lifetime warranty lets registered owners request replacements for damaged protectors, with the owner typically paying shipping and handling. It is a manufacturer program with its own registration requirements and terms, so register your protector when you install it and confirm the current process on Zagg's site when you claim.
Will a screen protector really save my phone screen in a drop?
It meaningfully improves the odds by absorbing and spreading impact energy, which is why cracked protectors over intact screens are such a common sight. No protector makes a phone invincible; a bad enough hit, especially on a corner, can still break the display. It is inexpensive risk reduction, not a guarantee.
