That sickening crack when your phone hits the floor. You pick it up, flip it over, and see a web of cracks across the glass. Before you panic there's a good chance the damage stopped at your screen protector, and the actual display underneath your iPhone or Samsung Galaxy is completely fine.
Here's the short version: a cracked tempered glass screen protector can't be repaired. The fix is to remove it, check the screen underneath, and replace it with a new one. This guide walks you through exactly how to do that safely, and how to avoid a repeat next time.
Is a Broken Screen Protector Fixable?
No, once tempered glass cracks, it's structurally compromised. There's no way to level the cracks or restore it to its original strength, so repair isn't really an option. The only real fix is replacing it with a new protector.
Leaving a cracked protector in place isn't a great idea either. Damaged edges can turn sharp, pieces can start lifting off the screen, and the protector stops doing its job properly. And no you shouldn't just stick a new protector over the broken one. That adds extra thickness, throws off touch sensitivity, and the cracked layer underneath is still there causing problems.
The right move is simple: take off the damaged protector, clean the screen, and put on a fresh one.
Protector Cracked or Screen Cracked? How to Tell
Before you remove anything, check your phone under bright light.
Signs it's just the protector:
-
Cracks or roughness are on the surface only
-
The phone displays normally and responds to touch everywhere
-
No dark spots, colored lines, or dead zones
Signs your actual screen may be damaged:
-
Black spots or dead zones
-
Colored lines (horizontal or vertical)
-
Areas that don't respond to touch
-
Flickering or distorted images
-
Cracks that seem to run underneath the protector, not on top of it
If you see any of the second list, don't assume it's just the protector get the phone checked before doing anything else.

How to Remove a Broken Screen Protector Safely
-
Turn off your phone. It's easier to see cracks and reduces the risk of accidentally touching a live screen while you work. Take off your case too, so you can reach the edges.
-
Tape over badly cracked areas. A strip of clear tape over the worst of the damage keeps loose glass fragments together while you remove it. Don't press down hard on the cracked glass while doing this.
-
Find an edge. Don't start in the middle of a crack work from a corner where the protector meets the screen. This is true whether you're removing a protector from an iPhone or a Samsung Galaxy; the process is the same across devices.
-
Lift the corner gently with a fingernail or a thin card never a blade or anything metal, which can scratch the display underneath. Go slowly as it starts to lift.
-
Peel it off at a slight angle, without forcing or bending it. Removing it slowly keeps glass fragments together instead of scattering them. If the adhesive is stubborn, a little gentle warmth around the edges can help loosen it avoid high heat or prolonged heating.
Once it's off, set the broken protector aside safely and move on to cleaning the screen.
Cleaning and Installing the New Protector
Dust, fingerprints, or leftover adhesive on the screen will cause air bubbles under your new protector, so clean thoroughly first with a microfiber cloth and the cleaning wipe that usually comes in the box. Make sure the screen is dry, dust-free, and free of any adhesive residue before continuing.
To install:
-
Line up the new protector against the camera cutout, speaker opening, and edges before removing the backing film.
-
Peel off the protective film.
-
Align the edges and cutouts with the screen.
-
Lower it into place and press gently from the center outward.
-
Smooth out any bubbles following the instructions that came with your protector.
Avoid touching the adhesive side with your fingers - oils affect how well it sticks. Browse our full range of screen protectors for iPhone and Samsung Galaxy if you need a replacement, including the 3D Tempered Glass Screen Protector for the latest iPhone and Galaxy models.
Can You Keep Using a Cracked Protector?
You can use one with minor cracks for a short while, but it's not really worth the risk. Cracked glass is already structurally weakened, so another knock can make the damage spread, and chipped edges can be sharp against your fingers. Replace it as soon as you notice real damage, rather than waiting for it to get worse, especially if the crack is near an edge or corner where the protector has started lifting.
Preventing It From Happening Again
Pairing your screen guard protector with a solid phone case is the easiest way to cut down on repeat breaks the case protects the edges and frame, the protector covers the screen, and together they cover a lot more of the phone. Check out our iPhone cases and Samsung Galaxy cases if you need one. Prefer something slimmer? Our ultra-thin cases add protection without the bulk.
A few other habits worth building:
-
Avoid pockets or bags where your phone sits next to keys or other hard objects
-
Check your protector regularly for small cracks, chipped edges, peeling, air bubbles, or lifting corners
-
Replace it at the first sign of damage rather than waiting for a full crack
Choosing a Better Protector Next Time
Not all screen guard protectors are made the same. Look for one designed for your exact phone model, precise cutouts and edge coverage matter for fit, camera access, and how it feels under your finger. A well-made protector shouldn't dull touch sensitivity or clarity; if it does, it's the wrong one for your phone.
Final Thoughts
A cracked screen protector looks alarming, but it usually means the protector did its job, not that your phone is damaged. Check the screen underneath, remove the broken protector, clean the display, and fit a new one. Pairing a quality protector with a good case gives your phone the best defense against drops and scratches going forward.
