Confidentiality is a human nature; however our smartphones expose this when in public. Curiosity from wandering eyes is undoubtedly uncontrollable. People sitting beside you or passing by tend to intentionally and unintentionally take a quick peek at your screen for many reasons. Celicious Privacy Plus for Samsung Galaxy S21 is a 4-way privacy screen protector that helps protect sensitive information from prying eyes by narrowing the viewing angle so that the screen is only visible to individuals directly in front of the screen. This is achieved via the embedded micro-louver technology that blacks out the screen at an angle of 45 degrees either side of the lit display without blurring or image distortion. It is engineered to offer privacy for when your smartphone is used in either portrait or landscape orientation. Celicious Privacy Plus adheres firmly to the screen with its advanced silicone based adhesive backing offering a smooth glossy surface.
