Tech-Protect Quick Set Spy+ 2-Pack Privacy Tempered Glass for Samsung Galaxy A18 4G / 5G (31156-0)

Privacy tempered glass Tech-Protect Quick Set Spy+ is a protective tempered glass featuring privacy-filtering technology that makes the screen content visible only to the person looking directly at the display. Anyone viewing from the side sees nothing but a dark screen — the glass effectively protects your privacy when using your phone on public transport, at the airport, or in any other public place.

Made from 9H hardness tempered material, the glass shields the display against scratches, cracks and impacts while maintaining full touchscreen responsiveness and crystal-clear clarity for anyone looking straight at the screen.

The set includes two protective glasses and a dedicated installation frame that ensures perfect alignment and bubble-free application. This comprehensive mounting system eliminates the typical problems associated with applying tempered glass, delivering a professional result on the very first attempt.

* Due to the varied edge milling of displays, a slight air halo may appear around the screen after installing the protective glass. This is a natural occurrence and depends on the specific edge milling of a given unit.

1 × Quick Set installation frame

1. Start the installation in the bathroom right after a shower – the steam will settle any dust in the air so it won't interfere with the process.


2. Thoroughly clean and degrease the screen surface, then polish it to a shine with a dry cloth.


3. Apply the glass as evenly as possible – you can use the positioning frame included in the set to align it perfectly.


4. Remove any air bubbles by pressing firmly across the entire surface in circular motions for several dozen seconds – do this to ensure the adhesive layer bonds to the screen as strongly as possible.
