Question 1

Will this screen protector work with my Samsung Galaxy S21 Ultra's in-display fingerprint sensor?**

Accepted Answer

Based on extensive user feedback, this tempered glass protector significantly interferes with the fingerprint sensor's functionality for most users. Many report the sensor becomes unreliable or stops working entirely. If you frequently use fingerprint unlock, this may not be the ideal choice for you.

Question 2

Is it really easy to install without getting bubbles or dust underneath?**

Accepted Answer

While the kit includes standard installation tools, achieving a perfect, bubble-free installation can be tricky. Some users on platforms like Reddit have mentioned challenges with alignment and persistent edge bubbles. We recommend installing in a very clean, dust-free environment and watching a tutorial video for the best results.

Question 3

I've heard some screen protectors make the screen less responsive. How is the touch sensitivity?**

Accepted Answer

A common observation is that touch sensitivity, particularly for light taps and edge swipes, can be slightly reduced. You may need to press a bit more firmly than on the bare screen. For optimal performance, ensure you enable "Touch sensitivity" in your phone's display settings after installation.

Question 4

What is your return policy if the product doesn't work with my phone's features?**

Accepted Answer

We stand by our products. If you are unsatisfied with your purchase for any reason, including compatibility issues with phone features, please contact our customer support within the return window. We'll help you process a return or refund. Please keep your original packaging.

Question 5

Are there screen protector alternatives that better maintain fingerprint functionality?**

Accepted Answer

Yes. Many S21 Ultra owners in online communities report better success with high-quality **TPU film protectors** for full fingerprint compatibility, or **UV glue-tempered glass kits** (from brands like Whitestone or AmFilm) which use a liquid adhesive to fill the gap between the glass and sensor. These are often recommended for users who prioritize biometric features.
