Tech-Protect Glass Spy+ is the perfect solution for users who value the privacy and security of their data. The privacy technology used limits the visibility of the screen to outsiders, protecting against unauthorized access, which contributes to increasing the confidentiality of our conversations and messages. The Tech-Protect Glass Spy+ also provides excellent protection for the display against scratches, bumps, and dents, ensuring that your phone stays in top condition for a long time. Its hardness level is rated by the manufacturer at 9H on a ten-point scale. It does not affect the touch sensitivity and saturation of the displayed colors. In addition, it is covered with a high-quality oleophobic coating, which minimizes the number of fingerprints left. It is also worth noting the incredible smoothness of the touch, which affects the comfort of using the phone. In addition, the easy installation procedure makes it affordable for anyone, even those who are inexperienced in glass installation. * Remember to remove and re-add fingerprints after installing the glass, if any. ** Due to the variety of milling of the edges of the displays, after the installation of any glass, a delicate air halo may form around the screen. This condition results from the very milling of the screen in a given piece. INSTALLATION INSTRUCTIONS: 1) Start installation in the bathroom right after bathing - the water vapor will absorb all the dust from the atmosphere and it will not interfere with your installation. 2) Clean and degrease the surface of the screen thoroughly, then use a dry cloth to polish it to a shine. 3) Install the coating as evenly as you can - you can position it with two sheets, gluing them to the side of the device. 4) Get rid of air bubbles by pressing the whole thing down in a circular motion for a few dozen seconds. Do this so that the adhesive layer bonds to the screen as tightly as possible.
