Privacy Screen Display turns your Android phone into a privacy powerhouse β protecting your screen from prying eyes wherever you are: on the bus, in a cafΓ©, at work, or on a plane.
The app draws a lightweight overlay directly on top of everything on your screen, making the content unreadable from side angles while staying clear to you straight on β just like a premium hardware privacy screen protector, but in software, for free.
π View Angle Mode β Samsung-Identical Privacy
Activate View Angle Mode for pixel-perfect 1:1 physical-pixel privacy stripes β the same optical louvre technique used by Samsung's flagship Privacy Display hardware. At 40Β°+ side angles the effective blocking coverage jumps to 70β80%, making text and images nearly impossible to read from the sides.
