Dust under a screen protector: how to get it out

A single speck under glass makes a bubble you'll see every time you use the phone. It's usually fixable in two minutes.

Short answer

Lift the nearest corner with a piece of tape until the speck is exposed, touch it with a dust sticker or tape, then lower the glass. Don't blow on the adhesive or wipe it with a cloth, which adds more lint.

Step by step

  1. Wash and dry your hands. Work in a steamy bathroom if you can.
  2. Press a strip of tape onto the protector near the dust and peel up slowly.
  3. Find whether the speck is stuck to the screen or to the adhesive.
  4. Touch it away with a dust sticker (from the kit) or a fresh piece of tape.
  5. Lower the protector, pressing from the centre outwards.

Stop it happening next time

  • Run a hot shower for three to five minutes and fit the protector in the bathroom.
  • Dust-sticker the whole screen, not just what you can see.
  • Peel the backing only when the glass is lined up and ready to lower.

Questions people ask

Will dust under a screen protector come out on its own?

No. It needs lifting out; waiting only helps with empty air bubbles.

Can I reuse a screen protector after lifting it for dust?

Yes, glass tolerates a few careful lifts. Film is less forgiving.
