How to properly apply the hydrogel film to your Oppo A78 4G?

Carefully clean the screen with a microfibre cloth. Remove any dust with the dusting decal. Align the film from the top, let it apply gradually, and smooth out any bubbles with a soft card.

Is the film really die-cut for the Oppo A78 4G?

Each film is cut to measure in France to exactly match the 6.43-inch screen of the Oppo A78 4G, with the correct cutouts.

What’s the difference between matte and anti-spy finishes?

The matte finish reduces reflections and fingerprints. The anti-spy version, in addition to that, limits the viewing angle of the screen to preserve your privacy in public.

Does hydrogel film damage the screen or leave residue upon removal?

No, the hydrogel adhesive is designed to protect without leaving any sticky residue when you decide to remove it, subject to correct application on a clean surface.

Presentation

This product is a hydrogel protective film, specifically designed for the screen of the Oppo A78 4G smartphone. It is a flexible and thin screen protection, applied directly to the glass surface of your device. The phone is not included in this sale. Prepared and cut in France on demand.

Available Finishes

Three variants of the same hydrogel film range are offered for this model: the standard clear finish, the anti-glare matte version for increased visual comfort, and the anti-spy option which limits the lateral visibility of your screen.

Why Choose Hydrogel

The hydrogel film is a flexible protection that perfectly follows the contours of your Oppo A78 4G screen, including any slightly curved edges. Its extreme thinness preserves the natural feel of the touchscreen and the clarity of the AMOLED display. It is an excellent flexible alternative to tempered glass, particularly suitable for helping to limit superficial scratches related to daily use.

Compatibility

This hydrogel film is die-cut for the Oppo A78 4G and its 6.43-inch screen. Its cut is specifically made for this model and the necessary openings for the front elements. It is perfectly compatible with most protective cases.

Application

For optimal application, ensure that the surface of your phone's screen is clean, dry, and dust-free. Carefully align the film, center it, and press gradually to make it adhere. Use a soft card to chase out any possible air bubbles towards the edges. Then allow it to naturally adhere for a few hours.
