Why choose CERAMIC 9D ceramic glass?
Classic tempered glass tends to crack or chip at the edges when exposed to strong impacts, requiring frequent replacement. Ceramic Glass represents a revolution in protection. It is an extremely durable combination that, due to its flexibility, does not break or shatter. It is equipped with a special unbreakable layer that absorbs the force of the impact and distributes it over the entire surface, effectively protecting the original screen of your phone.
Thanks to its thickness of only 0.2 mm, this protective glass is almost invisible. Despite its extreme thinness, it achieves a high hardness level of 9H, which means it is extremely resistant to scratches caused by keys, coins and other sharp objects in your pocket or purse.

Frequently Asked Questions (FAQ)
1. What is the difference between ordinary tempered glass and CERAMIC 9D ceramic glass?
Ordinary tempered glass is hard, but can crack or shatter under heavy impact. CERAMIC 9D ceramic glass combines the flexibility of a protective film with the hardness of glass. Due to this hybrid structure, the glass does not break, crack or shatter, which means a significantly longer lifespan of the protection.
2. Does using this glass affect the performance of the fingerprint reader on the Samsung Galaxy S21?
Due to its extremely thin thickness (only 0.2 mm) and high-quality material, the glass maintains excellent touch sensitivity. For optimal performance of the fingerprint reader after installing the glass, we recommend that you re-register your fingerprints in the phone settings and, if necessary, turn on the "Touch Sensitivity" function.
3. What do I receive in the installation kit?
The set includes a premium CERAMIC 9D ceramic protective glass, customized for the Samsung Galaxy S21, and a dedicated cleaning set (wet and dry cloth), which allows you to perfectly prepare the screen and easily install it without dust or bubbles.

Answers to frequently asked questions

Does this tempered glass cover the entire Samsung Galaxy S21 screen?

Yes, the CERAMIC 9D tempered glass screen protector is made specifically for the Samsung Galaxy S21 and is designed to adequately cover the entire screen surface, including the curved edges.

Will the touch feel be very different compared to an unprotected screen?

The feel in use remains very similar to natural glass, but due to the added thickness, you may notice minimal difference in smoothness or touch responsiveness.

What to do if bubbles appear under the glass?

If bubbles appear under the protective glass, we recommend that you clean the screen thoroughly before installation and repeat the process, as cleaning reduces the risk of trapped particles and bubbles.

Is the protective glass also suitable for use with a silicone case?

When should the protective glass be replaced?
