+1 to what was said earlier. i mean, the ultrasonic sensor is basically the most annoying part to get right, right?? i totally agree that those generic ones are a massive gamble... honestly i have been using these things for like 10 years and i still mess up the alignment every single time without a tray lol.

so i was wondering, are you looking for something with a privacy filter or just clear glass? also, what kind of case are you planning to use? cuz sometimes the ones that go all the way to the edge can actually pop off if the case is too tight...

Following this thread

Quick question - are u looking for a tempered glass one specifically or are you open to like, the TPU film style? I mean, the glass feels sooo much better but some people swear by the films for the fingerprint sensor. I've been eyeing the Spigen Glas.tR EZ Fit for Pixel 9 cuz of that alignment tray, but I wanna be sure it doesnt mess with the ultrasonic sensor before I pull the trigger. Ngl I'm kinda cautious after what happened to the last guy lol.

I have been looking into the technical specs for the Pixel 9 display assembly and honestly it is such a headache. There is so much concern about how these protectors are gonna hold up over the long haul. It feels like you have to be a literal engineer just to pick a piece of glass. A few things that are sketching me out:

• The ultrasonic sensor relies on really specific acoustic impedance, so even a tiny variation in the adhesive thickness can cause signal attenuation that gets worse as the glue cures.
• You gotta be careful with the edge tolerances because if the protector is even a fraction of a millimeter off, it can cause micro-lifting that traps dust against the glass.
• Refractive index issues on the cheaper materials are also a concern since they cause distortion when you are looking at the screen from an angle.
• Most of these companies dont mention the impact on the oleophobic coating after long-term heat exposure, which is a huge deal if you plan on keeping the phone for years. It is just exhausting that we are stuck dealing with these trade-offs...

> I’ve looked at the official Google Store options, but they seem a bit pricey compared to third-party ones like Spigen or amFilm.

Dude, I feel u. Honestly, I had a DISASTER with a generic brand last week—it basically ruined the ultrasonic sensor. Total waste of money... WARNING: Avoid those cheap-o generic ones without a frame cuz hand-applying is a nightmare on these curved edges. I'd go with Spigen tho. It fits the Pixel 9 perfectly and the sensor actually works. Its way cheaper than Google's stuff but feels just as premium, right?

i totally agree that the tray is a MUST if youre doing it yourself. i was checking the screen specs and since the pixel 9 is basically flat now - it should technically be easier to align? but yeah even with the best tray i ALWAYS end up with a tiny speck of dust... it drives me crazy. honestly i was wondering if its just better to pay for a professional install at a shop? i keep seeing those UV glue kits that are supposed to be the absolute BEST for the ultrasonic sensor response times but they look so complicated for a beginner like me to DIY. do those actually make a huge difference in the data read or is it just hype?

Good to know!
