Rarely post but saw this and had to chime in. Like someone mentioned, those UV kits are GREAT for the sensor but you dont actually have to pay a premium to get that level of stick. Ngl I used to be a total brand snob until I found the LK 2+2 Pack Tempered Glass for Galaxy S26. Its dirt cheap and they give you two of everything for like twelve bucks. Honestly the secret to the fingerprint sensor is just turning up the touch sensitivity in the settings and re-scanning your thumb... it works perfectly. Idk why people spend fifty bucks on a single piece of glass when these budget packs are basically the same thing. Just make sure the screen is TOTALLY CLEAN before you start or you'll get bubbles... if you mess up the first one its whatever because you have spares.

oh man this is EXACTLY my thing... i have tried literally everything for the S26 series since launch. honestly you dont need to spend $50 for one piece of glass when budget stuff is just as good now. i used to buy the boutique brands but they all crack eventually anyway and the fingerprint sensor always acts up if the adhesive is too thick. here are my go-to cheap picks that actually stay on:

• Spigen Glas.tR EZ Fit 2-Pack - best value tbh. the alignment tool is a lifesaver so you wont mess up and waste a sheet.
• amFilm OneTouch Glass 2-Pack - lowkey better for the scanner than the high-end brands and way cheaper.
• JETech Tempered Glass 3-Pack - if you are really trying to save money this is the one. three protectors for under fifteen bucks is INSANE. i almost went down a rabbit hole about adhesive viscosity specs but anyway... bottom line is just grab a value pack.

To add to the point above: this comes up a lot. Search the forum for "S26 lifting" and you will find several threads. Before buying another, are you using a case with a high front lip? If the case frame presses against the edge of the glass, it will lift regardless of the brand. For the S26, standard adhesive often fails. Liquid Optically Clear Adhesive (LOCA) kits provide the best bond for the ultrasonic sensor.

• Whitestone Dome Glass UV Gen 2 - $45 for a 2-pack. Uses liquid glue and UV lamp. Most reliable for the fingerprint scanner.
• Milomdoi UV Glass 3-Pack - $32. Budget alternative using the same UV process.
• Dbrand Prism 2.0 Screen Protector - $30. Designed for high impact resistance. Cure the edges with the UV light for 120 seconds to ensure a permanent seal.
