How to Fix a Cracked Phone Screen: A Beginner’s Guide

How to Fix a Cracked Phone Screen: A Beginner’s Guide

Should You Repair It Yourself?

DIY repair is best if:
✔ The crack is minor (no deep shattering or touch issues).
✔ You have a mid-range or older phone (cheaper parts).
✔ You are comfortable with small tools (screwdrivers, pry tools).

Consult a professional if:
✖ The display is completely black/unresponsive.
✖ The phone is under warranty (DIY may void the warranty).
✖ Your phone is a foldable phone (much harder to repair).

Tools You’ll Need

Before starting, gather these essentials:

  • Replacement screen (make sure it’s compatible with your phone model)
  • Precision screwdriver set
  • Plastic pry tools (to avoid scratching)
  • Suction cup or guitar pick
  • Tweezers
  • Heat gun or hairdryer
  • Adhesive strips or glue
  • Microfiber cloth

Step-by-Step Repair Guide

Step 1: Back up your data

Warning: There is a risk of losing data when opening your phone. Please back up to Google Drive, iCloud or your computer first!

Step 2: Power off & remove SIM card

  • Turn off the phone completely.
  • Use a SIM eject tool (or a paper clip) to remove the SIM card tray.

Step 3: Soften the adhesive

  • Heat the edges of the screen with a hair dryer (2-3 minutes) to loosen the glue.
  • Do not overheat! ~60°C (140°F) is sufficient.

Step 4: Lift the screen

  • Place a suction cup near the bottom edge.
  • Use a plastic pry tool to gently pull upwards to separate the screen.

Step 5: Disconnect the old screen

  • Locate the ribbon cables (usually on the top or bottom).
  • Use a spudger to carefully unplug them

Step 6: Install new screen

  • Connect new screen's cables (match old cables).
  • Test it before sealing! Power on to check touch/display.
  • Apply new adhesive around the edges.
  • Press firmly for 30 seconds to seal.

Step 7: Reassemble and test

  • Put back all screws and covers.
  • Check touch, brightness, and buttons before finalizing.

Pro Tips to Avoid Mistakes

  1. Label the screws with tape to avoid mixing them up.
  2. Work in a clean, well-lit area (lost screws can be frustrating!).
  3. Watch a teardown video of the same model as yours(YouTube/IFixit).
  4. Don't force anything -- if it won't budge, check for hidden screws.

Common Beginner Mistakes

❌ Using metal tools (may scratch your phone or cause a short circuit).

❌ Skipping the adhesive (dust can get inside).

❌ Not testing before sealing (you don't want to reopen it!).

Still Nervous? Try These Alternatives

  1. Use a temporary screen protector (hides the crack and prevents further damage).
  2. Trade in your old screen for a new one (some stores will accept cracked screens at a discount).
  3. Sell parts (eBay etc).

Final Verdict: Is DIY Worth It?

✅ Yes, if: You have patience, the right tools, and own a mid-range phone.
❌ No, if: You own a new flagship phone (like iPhone 16 Pro, Galaxy S25 Ultra) - professionals will do a better job.
