The Nillkin Guardian Full Privacy for the Samsung Galaxy S25 Edge is a black tempered glass screen protector designed to keep your personal information secure from prying eyes. It features a specialized privacy filter that limits the viewing angle to 28°, meaning the display remains visible only to you while appearing dark to anyone looking from the side. Constructed from 9H hardness glass with a thickness of 0.33mm, this single-piece protector guards against scratches and abrasions without sacrificing touch sensitivity. The 2.5D arc edge provides a smooth transition to the phone's frame, while an oleophobic coating helps reduce fingerprints and an anti-glare finish improves visibility in bright light. To ensure a precise fit, it comes with a case-based pull-and-done installation applicator along with a full cleaning kit.
