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).

Not sure what it might be but shape and position match those of the wireless charging coil.

That wouldn't be behind the screen nor rectangular

Charging coils can absolutely be rectangular.

They can't be behind the battery, though, so this can't be it.

They also can't be that long and still work with any efficiency.

Oh, I thought that OP was asking for the circular shape, the rectangular one looks more like some short of graphic showing on the screen. But maybe the circle is just the reflection of the flashlight?

[–] Joeffect@lemmy.world 4 points 3 months ago

Yes, the circle is light from a light source...

Wouldn't that be on the back side of the phone though? I suspect the battery would be between the coil and the display, making it impossible to see from this side under any kind of light.

That said, I donno WTF we're seeing.

Pretty sure it was Mrfriki's guess.

They might have posted first but ShepherdsPie actually realized it first. I was there.
