Why choose CERAMIC 9D ceramic glass?
Everyday use of your phone brings risks, such as falling onto hard surfaces, coming into contact with keys in your pocket, or dropping your phone on rough surfaces. Standard protective glass often cracks or shatters upon a strong impact, requiring immediate replacement. 9D ceramic glass, however, is equipped with a special shatterproof layer. This means that it absorbs impacts without crushing or cracking into dangerous sharp fragments. This will keep your Samsung Galaxy A42 5G safe, and you will save time and money on constantly changing protections.
Despite its exceptional hardness of 9H, which ensures maximum scratch resistance, this glass is incredibly thin. At just 0.2mm thick, it's almost invisible on the screen. It doesn't add to the weight of your phone or alter its elegant design, while ensuring flawless touchscreen responsiveness.

Full functionality and invisible protection
Are you worried that a protective glass will degrade the image quality or responsiveness of your screen? With CERAMIC 9D glass, these concerns are unnecessary. High light transmittance ensures that the colors on your screen remain vibrant and the contrast is exceptional. The nano coating on the surface ensures that your fingers glide smoothly across the screen, while also repelling water, oil and dirt. This will keep your phone looking clean and tidy.
Thanks to the full adhesive layer (the adhesive is applied over the entire surface of the glass, not just on the edges), the glass is completely fused with the screen. This prevents the "rainbow effect" and ensures that touch sensitivity is not reduced even for a split second. Your user experience remains the same as if you were using your phone without protection, but with the peace of mind that your device is safe.

Frequently Asked Questions (FAQ)
1. What is the difference between ordinary tempered glass and 9D ceramic glass?
Ordinary tempered glass tends to crack or shatter at the edges when hit hard. CERAMIC 9D ceramic glass combines the flexibility of a protective film with the hardness of glass. Due to its hybrid composition and unbreakable layer, it does not shatter or crack when hit, which means a significantly longer lifespan of protection with the same level of safety (9H).
2. Does the glass cover the entire screen of the Samsung Galaxy A42 5G, including the edges?
Yes, thanks to advanced 9D technology, this glass is designed to precisely cover the entire surface of the screen, including its rounded edges. This provides comprehensive protection against damage and prevents dirt from accumulating in the passages.
3. Will installing glass affect the touch screen sensitivity?
Not at all. The protective glass is only 0.2 mm thick and uses Full Glue, which ensures direct contact with the screen. The touch sensitivity and responsiveness of the screen remain completely unchanged.
