The side-angle blocking actually works; my screen goes dark when someone leans over.

Early Black Friday Sale
Keep Your Screen Private in Public Spaces
This anti-spy screen protector adds a darkening layer that blocks side-angle visibility while keeping your display crystal-clear from the front. Built from tempered glass, it sits flush over your Samsung's screen to guard against scratches, fingerprints, and prying eyes. Each protector is precision-cut for a specific Galaxy model—S21 Ultra, S21 Plus, S21, S20 FE, S20 series, S10 series, S9 series, S8 series, and Note 20, 10, 9, or 8—so you get exact edge alignment, full touchscreen response, and unobstructed camera and sensor windows. Choose the UV lamp kit if you want the liquid-adhesive installation method for curved screens, or select the standard version for flat or lightly curved displays. Either way, you're adding a privacy barrier that works the moment someone glances at your phone from the side.

Why You Need This
- Side-Angle Privacy: The darkening filter makes your screen unreadable from 30° or more to the side, so commuters, coworkers, and passersby see only a black panel.
- Exact Model Fit: Pre-cut to match the screen dimensions, camera notch, and speaker grille of your specific Galaxy phone—not a generic universal size.
- Tempered Glass Barrier: The 9H-hardness glass layer deflects keys, coins, and everyday scratches that would otherwise mark the factory screen.
- Full Touch Sensitivity: The ultra-thin glass preserves the Galaxy's native touch response, so swiping, typing, and gesture controls feel unchanged.
- UV Lamp Option: Curved-screen models (like the S21 Ultra or Note 20 Ultra) benefit from the UV-curing adhesive, which bonds the protector seamlessly to 3D edges.
- Case-Friendly Design: The slightly recessed edges leave space for most phone cases without lifting the corners or creating bubbles along the sides.
Built for Daily Defense
Install it in five minutes with the included alignment tray and microfiber cloth, then forget it's there—until you notice strangers can't snoop on your texts or emails. The oleophobic coating resists fingerprint smudges and wipes clean with a single swipe, so your screen stays clear even after a full day of use. If you ever crack the protector, it absorbs the impact and sacrifices itself to save the Samsung's original display underneath. We ship every order from our US warehouse with tracking, and you have 30 days to return it if the fit isn't perfect or you change your mind. No hidden fees, no restocking charges—just straightforward privacy protection for your Galaxy phone.

What Our Customers Say
Discover what makes THOMLER special.
Fits my S20 perfectly, no bubbles or lifting at the edges after two weeks.
Tempered glass feels premium and doesn't affect how my phone responds to touch.
I was skeptical about privacy screens until I saw how dark the display gets from the side. Now I use it every day on my S21—totally worth the investment for peace of mind.
The UV lamp kit made installation super clean on my curved S21 Ultra screen. Adhesive cured evenly and there's zero peeling at the corners after a month of daily use.
Ordered the standard version for my Note 10 and the alignment tray made setup foolproof. Fingerprints wipe right off and the screen looks crystal clear head-on, which is exactly what I needed.
