Fixing a Cracked Mobile Phone Screen at Home

February 25, 2024

Introduction

A cracked phone screen is an annoying and common issue for many smartphone users. While a cracked screen can often be fixed by replacing the entire display assembly, this repair is expensive and time-consuming. Thankfully, there are ways to temporarily fix a cracked phone screen at home, which I’ll cover here.

Assessing the Damage

Before attempting to fix a cracked phone screen, it’s important to thoroughly assess the damage. Here are some key things to check:

Type of crack – Is it a small hairline fracture or a major smash/shatter? Minor cracks may be fixable but large cracks likely require full display replacement.
Touch functionality – Does the touchscreen still work properly or is it unresponsive in the cracked area?
Display visibility – Can you still clearly see the screen or is it obscured by cracks?
Other damage – Inspect for any other damage like dents, scratches or water damage. Fixing the screen won’t help if there are other major issues.
Phone model – Know your exact phone model to ensure you get the right replacement parts later if needed.

Cleaning the Screen

Before attempting a DIY phone screen fix, it’s crucial to clean the screen properly. Here’s how to clean a cracked phone screen:

Remove case/cover – Take off any case or screen protector to allow full access to clean.
Use compressed air – Use a can of compressed air to blow out any loose glass shards or debris.
Wipe with cloth – Gently wipe the screen with a soft, dry microfiber cloth to remove dust and dirt.
Isopropyl alcohol – Use a cotton pad and isopropyl alcohol (70% or higher) to sanitize the screen and kill germs. Be very gentle.
Avoid using liquids which could seep into cracks and cause damage. Take your time to thoroughly clean and inspect the screen.

Temporary Crack Fixes

Here are some temporary DIY methods to fix a cracked phone screen at home:

Clear packing tape

Carefully apply strips of clear packing tape over the cracked screen area.
Tape helps hold cracked glass in place and prevents further cracking.
Doesn’t work well for major shattering but can fix hairline cracks.

UV liquid screen protectors

UV-cured liquid screen protectors act as a clear adhesive layer over the screen.
More durable and longer-lasting than packing tape.
Levels out screen cracks and scratches to improve visibility.
Can purchase at stores or online for around $10-20. Follow included instructions.

DIY screen repair kits

Affordable DIY screen repair kits can be purchased online.
Usually include UV liquid adhesive, curing lamp, applicators and instructions.
Offers a more advanced liquid screen protector solution compared to basic products.
Kits cost $15-30 but are reusable for future repairs.

When to Do Full Replacement

If the cracks are too large, cause significant visibility issues or unresponsive touch control, then a full screen replacement is likely needed. Here’s what to consider:

Phone warranty – Cracked screen may be covered under warranty, allowing free manufacturer repair.
Repair shops – Local phone repair shops can replace the screen but can be pricey ($100-250+).
DIY replacement – Order a screen + digitizer replacement online for $20-100 and do it yourself. Highly complex.
New vs used – Replacement can be done with new or used screens. Used is cheaper but may have defects.
Other damage – If phone has any other significant damage beyond the screen, replacement costs increase. May be more worthwhile to buy a new phone.

Preventing Future Cracked Screens

To help prevent dealing with cracked screens again, here are some tips:

Use a protective phone case – Tough cases can stop cracks from drops.
Install a glass screen protector – Adding a glass protector layer helps protect the actual phone glass underneath.
Be careful in handling – Avoid dropping, tossing or storing phone in unsafe places like pockets. Use phone straps.
Only use soft cloths to clean – Avoid abrasive materials when cleaning display.
Consider insurance – Phone insurance can offset repair/replacement costs if you do crack the screen.

Conclusion

Fixing a cracked phone screen doesn’t require an expensive trip to the repair shop. Using clear tape, liquid screen protectors or DIY kits can temporarily fix cracked screens, especially if damage is minor. But for major cracking or shattering, a full screen replacement may be necessary. With the right methods and by taking preventative measures, you can successfully fix and avoid cracked phone screens.
