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).

The AI is definitely why. It's not well liked on Lemmy and Gemini is especially bad when it comes to credible information.
That said, I'm sure this is one rare occasion where it's probably the right answer. Glue is really the only thing anyone has suggested that makes sense to me, as it's the only thing that would be where it is and glow under UV light. Well... I guess it could be cum. 🤔
I'm just not sure about that being correct, though. It shouldn't be correct. I repair phones all the time, including screens and digitizers. All the adhesives are edge to edge. If this screen looks completely fine in normal light with no air gaps or peeling or anything, I can't think of any reason why this would be going on. It can't really exist where the oled and the digitizer/outer glass are.
My guess is that it's something attached to the back side of the oled, further inside the phone. The adhesive used to bind the oled and digitizer together doesn't show up under UV light. There also wouldn't be two different adhesives used.
