Installation Information

The Galaxy Z Fold4 inner screen may already have a factory-installed protective film. Do not apply this hydrogel protector over the existing film.

If the original protector is lifting, bubbling or damaged, professional removal and replacement are strongly recommended. The folding display is more delicate than a conventional smartphone screen and may be damaged by excessive pressure, sharp tools or incorrect installation.

For best results:

1. Confirm that any existing inner-screen protector has been safely removed.

2. Clean the display carefully using suitable materials.

3. Remove all dust before applying the new protector.

4. Align the film precisely with the screen and central fold.

5. Apply it without stretching or using excessive pressure.

6. Allow small installation marks or moisture to settle naturally.

Important Information

This hydrogel film helps protect against scratches and everyday surface wear. It does not provide the same impact resistance as tempered glass and cannot guarantee protection against drops, crushing or display damage.

Do not use rigid tempered glass on the folding inner display. Avoid pressing the protector into the crease with fingernails, cards or sharp installation tools.

Small bubbles or installation marks may gradually reduce after application. Larger bubbles, lifting edges or incorrect alignment may require the protector to be replaced.

Removing the factory-installed protector or performing an incorrect installation may affect warranty or repair eligibility. Check Samsung’s current service guidance before removing the original inner-screen film.
