UV Light on sister's phone; what's with the blue oval? (yiffit.net)

Sister was messing around with a UV light and noticed this on her phone screen under it. My phone does not have this (all I get is a grid of dots I'm pretty sure are to do with the touch screen).

Would have been a lot more fun if the hand was speckled with suspicious white stains!

Google Gemini says:

The oval shape you're seeing on your Pixel 8's screen when exposed to UV light is likely due to the adhesive used within the phone's display assembly. Here's why:

UV-reactive adhesive: Many modern phones use adhesives that contain fluorescent materials. These materials glow when exposed to UV light.
Display layers: The adhesive is typically used to bond the various layers of the display (such as the glass, touch sensor, and LCD/OLED panel) together.
Visible pattern: The pattern of the adhesive can sometimes be seen as an oval shape or other pattern when viewed under UV light. Important Note: While this is a common occurrence and generally harmless, it's always a good idea to avoid prolonged exposure of your phone to UV light. Excessive UV exposure can potentially damage the phone's screen or other components over time. Let me know if you have any other questions.
