Can vouch for this

Sooo, basically with the Nord's optical sensor, the thickness of the glass actually matters a lot for the refraction index. If the adhesive isn't uniform, it'll mess with the fingerprint read rates highkey. Honestly, before I give a solid recommendation, I gotta ask: are you looking for a full-adhesive tempered glass that needs UV curing, or just the standard dry-apply ones? Also, does ur current case have a high lip around the screen?? Some of the 'budget' tempered glass brands tend to be slightly oversized, which causes lifting at the edges if ur case is too tight. I've dealt with so many that literally just pop off after a day lol. Just lemme know those two things so I can tell u which specs to look for!

Good to know!

TL;DR from this thread: the optical fingerprint sensor is the big technical hurdle here because glass thickness and adhesive quality literally change the light refraction. I've tested a bunch, and honestly, the OnePlus+Nord+3-Pack&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">IBYWINI Screen Protector for OnePlus Nord 3-Pack is the budget king! It's usually under $10 and keeps the biometric speed FAST. If you want a more premium feel without the price tag, OnePlus+Nord&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">amFilm OneTouch Tempered Glass for OnePlus Nord is another solid pick for like $12. GL!

Seconding the recommendation above. Honestly, that point about the optical sensor is SO important because I've seen cheap glass literally ruin the biometrics. Are you leaning towards a film protector or tempered glass tho?

Would love to know this too

Ok adding this to my list of things to try. Thanks for the tip!

Like someone mentioned, the oleophobic coating is where these budget brands always fail. Its honestly frustrating. Friction increases so fast on these cheap panels. Ive been measuring light refraction levels on a few generic sets for the Nord lately and unfortunately most are pretty disappointing. They basically mess with color accuracy more than people realize. Ive also had issues with touch latency being way higher than advertised. Honestly, most are just not as good as expected... Before I look through my data, what are you actually looking for? Do you want a specific thickness like 0.33mm for impact safety, or is 0.2mm the goal to keep that fingerprint sensor snappy? Also, do you care about the black border found on some full-coverage glass, or do you want a totally clear piece?

Honestly, most people focus on the initial fit, but I’m always more concerned about how the oleophobic coating holds up after a month of heavy use. I've tested a few 'budget' options where the fingerprint sensor worked fine on day one, but the friction increased *so much* once the factory coating wore off. Before I drop a specific name, are you using your phone in a pretty dusty environment or maybe at the gym a lot? Sweat and grit can really tear through those cheaper layers. If you want something that actually holds up to real-world abuse, I've had pretty solid results with the Mr. Shield Tempered Glass. It’s usually super cheap for a multi-pack, and in my experience, the clarity stays high even after a few drops. The touch response is basically identical to the bare screen, which is the main thing I look for. Just a heads up though—regardless of what you buy, I'd definitely re-register your fingerprints *after* the install to make sure the sensor calibration is spot on.
