Does a mobile privacy screen really work?
Yes, Pxin.in mobile privacy screens use a special micro-louver technology that blocks side-angle visibility, ensuring that only the person directly in front of the screen can view it. It Protects your data from shoulder-surfers in public spaces.
Is it compatible with my deviceRedmi K40 Mobile?
Yes, the Redmi K40 Mobile Privacy Screen guard is custom-cut for your device. Just select the correct model before checkout.
How does a privacy screen guard block side-angle viewing?
Your Redmi K40 Mobile Privacy Screen Guard uses vertical optical filters that narrow the screen's viewing angle (usually to 28??-30??), making the screen appear black or tinted from the side while remaining clear from the front.
What is the difference between anti-glare and privacy filters?
Anti-glare filters reduce screen reflection in bright light. Privacy filters add side-angle blocking. Pxin.in combines both - you get glare reduction plus privacy Protection in one screen guard.

Yes, our filters are powered by BLUVLIGHTBLOCK ? technology that blocks up to great extent of harmful blue light, reducing eye strain, dryness, and sleep disruption.
Can I watch movies with this privacy screen?
Yes. Pxin.in's exclusive Movie+ feature allows full-screen clarity when you rotate your phone horizontally for video watching, while maintaining privacy in portrait mode.
Will this Protect my eyes from digital eye strain?
Absolutely. Your Redmi K40 Mobile Privacy Screen guard has anti-blue light layer along with anti-glare coating, which helps reduce eye fatigue from long hours of phone use, making it ideal for work, reading, and gaming.

Pxin.in Provides both case-friendly and full-coverage options. Please check the Product variant for edge compatibility on curved models.
