Frequently Asked Questions (FAQ) about the product
1. Does the 9D protective glass affect the responsiveness of the touch screen?
No. Thanks to the ultra-thin profile (only 0.3 mm) and high-quality 9H tempered glass, the touchscreen's responsiveness remains completely unchanged. The phone will respond instantly to your every touch and gesture.
2. What is the difference between regular glass and 9D protective glass?
Ordinary screen protectors often only cover the flat part of the screen, leaving the edges unprotected. The 9D screen protector is designed to perfectly fit the entire surface of your Samsung Galaxy A11's screen, including the rounded edges. This ensures better aesthetic integration and a significantly higher level of protection against side impacts.
3. Will there be a haze effect or color change under the glass?
Not at all. Our 9D tempered glass is made of specially treated, completely transparent glass that prevents the effect of surface haze. The high light transmittance ensures that the colors and brightness of the screen remain exactly the same as without protection.
