Question 1

Will this hydrogel screen protector work properly with the OnePlus Nord 4’s in-display fingerprint scanner?

Accepted Answer

Yes, for the most part. The film is designed to support fingerprint reading, but a few users on Reddit noted that sensitivity can drop slightly after installation. The key is to re-register your fingerprints once the protector is applied and ensure no air bubbles sit over the sensor. If you press firmly, it should unlock reliably most of the time.

Question 2

I’ve heard hydrogel films are tricky to install. Does this one come with a tool to help?

Accepted Answer

It does come with a basic installation kit—usually a cleaning cloth, dust sticker, and a squeegee card. However, many TikTok reviewers warned that the lack of a plastic alignment frame makes centering a bit fiddly. We recommend watching a quick “how-to” video before you start, and working in a dust-free room. Go slowly from the center outward to minimize bubbles.

Question 3

How durable is this screen protector? I’m worried about scratching and yellowing over time.

Accepted Answer

The hydrogel material has a self-healing layer that can make light surface scratches disappear within 24 hours, which is a nice perk. However, it won’t resist deep gouges or drops like tempered glass would. Regarding yellowing, several long-term users mentioned the edges can develop a slight amber tint after about a month, especially if you use a UV screen cleaner. For basic scratch defense, it holds up well—just don’t treat it like a heavy-duty armor.

Question 4

Does this protector leave gaps on the edges of the curved screen? I’ve seen complaints about dust collecting.

Accepted Answer

Some users have reported a very thin gap—roughly 1mm—along the curved sides, which can trap lint over time. The fit is designed to be case-friendly, so if you use a slim case, the gap is less noticeable. For a tighter edge-to-edge look, you may need a full-adhesive glass protector instead. Overall, the coverage is good for most daily use, just not 100% seamless.

Question 5

What is the return or refund policy if this film doesn’t fit my OnePlus Nord 4 properly?

Accepted Answer

The seller generally offers a standard 30-day return window for defective or damaged items. If the protector arrives with a manufacturing flaw (like incorrect cutouts), you’re covered. For fit issues like the edge gaps mentioned above, policies vary, so it’s best to message the seller before purchasing. Some buyers have successfully gotten a replacement by sharing photos of the fit. Always keep the original packaging just in case.
