When Do You Need to Fix Tempered Glass?
You should consider fixing or reapplying tempered glass if:
-
Air bubbles appear under the glass
-
Dust is trapped during installation
-
The edges are lifting or peeling
-
The glass feels misaligned
If the tempered glass is cracked or chipped, fixing won’t help — it’s best to replace it completely.
Things You’ll Need
-
A microfiber cloth
-
Wet/dry wipes or rubbing alcohol
-
Dust-removal stickers
-
Plastic card (optional)
Step-by-Step Guide to Fix Tempered Glass in Mobile
1. Check the Glass Condition
-
If the tempered glass is intact (not broken), you can reapply it.
-
If it’s cracked, replace it with a new one instead of fixing.
2. Remove the Glass Gently
-
Lift one corner using your fingernail or a plastic card.
-
Peel it slowly to avoid damaging the actual phone screen.
3. Clean the Screen
-
Wipe the screen with alcohol or wet wipes to remove dust and smudges.
-
Use a microfiber cloth to make it completely dry and spotless.
-
Pick off any tiny particles with dust-removal stickers.
4. Reapply the Tempered Glass
-
If reusing, clean both sides of the glass carefully.
-
Align the glass with your phone’s edges and camera cutouts.
-
Place it slowly on the screen and press in the middle — the adhesive will spread evenly.
5. Remove Bubbles
-
Use your finger or a microfiber cloth to push bubbles outward.
-
If a bubble is caused by dust, lift the glass slightly, remove the dust, and press again.
Tips to Keep Tempered Glass Secure
-
Always install in a dust-free room.
-
Avoid pressing hard on the edges of the glass.
-
Use a phone case to prevent the tempered glass from peeling off.
Final Thoughts
Fixing tempered glass in mobile is quick and easy if the glass is not cracked. By carefully removing, cleaning, and reapplying, you can restore full protection without replacing it. However, if the glass is broken, a new one is the only safe option.
