Look closely at the bubble. Clear with nothing inside: push it towards the nearest edge with a card and wait 24–48 hours. A speck in the middle: it's dust. Lift that corner with tape, dab the speck with a dust sticker, and lower the glass again. A rainbow ring round the edges: the glass doesn't match the screen's shape.
Identify the bubble
| Looks like | Cause | Fix |
|---|---|---|
| Clear, no centre speck | Trapped air | Press to edge; wait 24–48 h |
| Tiny white dot in the middle | Dust particle | Lift, remove dust, relower |
| Rainbow halo round the edges | Rim adhesive / curve mismatch | Different protector type |
| Milky patch | Adhesive not bonded (often film) | Press firmly; wait; replace if it persists |
Lifting glass to remove dust
- Stick a strip of tape to the corner nearest the dust and lift slowly until you can see the speck on the adhesive or screen.
- Touch the speck with a dust sticker or a second piece of tape. Don't touch the adhesive with your fingers.
- Lower the glass back down gently and press outwards from the centre.
Tempered glass adhesive tolerates a few lifts. Film creases easily, so be gentler or accept replacing it.
When to give up
Several dust bubbles, a bent film, or an edge halo that won't settle after two days are signs to replace the protector. Fit the next one in a steamy bathroom. See the installation guide.
Questions people ask
Do screen protector bubbles go away on their own?
Clear air bubbles usually do within 24–48 hours. Bubbles with dust inside don't.
Can I use a credit card to remove bubbles?
Yes, wrapped in a microfibre cloth to avoid scratching, pushing towards the nearest edge.
