Adding my two cents: don't overspend. Skip the UV hype and grab IMBZBK Tempered Glass Screen Protector. It's way cheaper, includes a camera protector, and the kit is actually reliable for under $15.

Honestly, everyone always hypes up Whitestone Dome Glass like it's the holy grail, but for the OnePlus 15, I really dont think it warrants the extra cash. Youre basically paying for an elaborate glue kit that is a nightmare if you mess up the installation even slightly. If you get a single bubble or dust particle, your day is ruined. I swapped to the Spigen Glas.tR EZ Fit recently and it just works. The alignment tray is actually idiot-proof, which is more than I can say for those complicated UV light setups. It feels fine, touch sensitivity is basically 1:1, and it doesnt lift when I slap on a case. A lot of those glowing reviews for the expensive stuff are just paid marketing, so dont fall for the hype. Real owners know that simple is usually better. Quick tip: wipe your screen down with a microfiber cloth in a steamy bathroom to cut down on dust in the air before you apply anything. Also, dont press too hard on the center during install; let the adhesive do the work naturally so you dont get those annoying halos on the edges. Save your money for a better case or just buy an extra pack of the cheaper glass since you have a curved display anyway...

TL;DR: Stick to simple alignment trays. Honestly, I totally agree about the UV glue kits being overkill. Most people just get blinded by the fancy marketing and think higher price equals better protection, but it really just equals a higher chance of ruining your phone during install. Also, check your case clearance before buying; a lot of these tempered glass options are cut just a hair too wide for some heavy-duty cases.
