The flagship Galaxy S26 series features Qualcomm’s advanced 3D ultrasonic fingerprint sensor, widely praised for its exceptional accuracy, speed, and security. However, this type of sensor is highly sensitive to screen protectors, which can often result in slower response times or even recognition failure. As a result, truly reliable solutions on the market remain extremely limited.

With years of dedicated research, DeFF has worked closely with component and sensor manufacturers to overcome this challenge, developing a glass screen protector with near-zero latency. For devices equipped with similar fingerprint sensors, DeFF’s solutions have already been officially recognized for compatibility. Even on the Galaxy S26 series, it delivers fingerprint performance comparable to using the device without a screen protector.

Features a highly breathable adhesive layer for a smooth, effortless application. The moderate adhesive strength allows easy repositioning, and any trapped air can be gently pushed to the edges for quick, bubble-free removal.

Multiple coatings on the glass surface create an ultra-smooth, silky feel for an exceptional touch experience. Dirt and smudges are easily wiped away—even fingerprints or makeup residues can be cleaned off effortlessly.

The glass edges are finely rounded with a large-radius curve, greatly reducing any obstruction when swiping from the screen edges. Additionally, the slightly smaller-than-screen design prevents interference or pressure when used with a phone case.

With a special shatter-resistant film, even if the glass breaks, fragments won’t scatter or cause injury. This safety-focused design provides added peace of mind during use.

With the included easy alignment tool, anyone can precisely apply the screen protector in the correct position.

STEP 1: Use the provided alcohol pad to wipe the surface of the phone screen, then use the eyeglass cloth to clean again 

STEP 2: Attach the DIY tool to your phone 

STEP 3: Peel off the protective film from the glass protector 

STEP 4: Align the glass protector along the edges of the DIY tool 

STEP 5: If there are any remaining air bubbles, gently push them outwards 

STEP 6: Remove the easy application tool (make sure not to remove the glass protector)
