Yes, when you choose a compatible screen protector. The Galaxy S26 uses an ultrasonic fingerprint sensor under the display. For reliable fingerprint recognition: Select protectors labeled "ultrasonic fingerprint compatible," avoid protectors with air gaps (full-adhesive or UV-cured tempered glass works best), after installation, delete existing fingerprints and re-register them, pressing firmly at multiple angles, and lastly enable "Touch sensitivity" in Settings > Display if needed. Registering the same finger in two fingerprint slots can also improve recognition rates.

Yes, even though the S26 Ultra features Gorilla Glass Armor 2 with built-in anti-reflective coating and enhanced scratch resistance. While this is Samsung's most durable display glass yet (reducing glare by 75% and resisting most everyday scratches), it can still be scratched by sand, quartz, and other hard minerals commonly found in pockets and bags. A Belkin screen protector provides a replaceable sacrificial layer, preserving your display's pristine condition and protecting your investment. It's far cheaper to replace a screen protector than to repair a scratched display.

For curved screens like the Galaxy S26 series, UV-cured tempered glass protectors offer the best combination of protection and fingerprint sensor compatibility. The liquid adhesive fills the curved edges completely, eliminating the "halo effect" (rainbow edges) common with traditional tempered glass. Alternatively, flexible TPU or hydrogel film protectors conform naturally to curved displays and work reliably with ultrasonic fingerprint sensors. Avoid rigid tempered glass with edge-only adhesive, as it often lifts at the curves and creates air gaps.

For bubble-free installation work in a clean, dust-free environment. Clean your screen thoroughly with the included alcohol wipe and microfiber cloth, use the dust removal stickers to lift any remaining particles, align the protector using the installation frame or guide tabs if included. Apply from one edge and slowly lower while pressing out air. Use the squeegee card to push any bubbles toward the edges. Small bubbles often disappear within 24-48 hours as the adhesive settles.
