Cracked screen protector: keep it or replace it?

A cracked protector usually means it did its job. Leaving it on for weeks is where problems start.

Short answer

Replace it soon. The crack shows the protector absorbed an impact, but cracked glass catches skin, lets grit reach the real screen, and can hide damage underneath. Tape over it, peel it off, and check the display before fitting a new one.

Why not just leave it?

  • Grit gets through cracks and scratches the screen underneath.
  • Sharp edges catch fingertips and cheeks during calls.
  • Touch problems can develop along crack lines.
  • It hides real damage, which matters if you're claiming on insurance or selling.

Removing shattered glass safely

  1. Cover the whole protector with clear packing tape so pieces stay together.
  2. Lift a corner with a plastic card, not metal.
  3. Peel slowly and steadily.
  4. Clean any fragments with tape, never by wiping.
