anybody got any ideas what's going on with my phone screen??

I'm sending it back to the big Goog because apparently it's still under warranty (I bought it second hand)

but it's the first time I've seen a phone screen do quite... this

@cyberia So, it was Zalgo after all?
@amaral that or some kind of eldritch horror. I'm scared to go to sleep with it in the same room.
@cyberia Is it next to one of the side buttons?
@amaral yeah it's quite near the power button. you can just see in that picture where the case stops to allow access to the power and volume buttons
@cyberia Once something quite similar happened to a phone of mine; as far as I could tell, because the power button was flaky, I had to press it harder, which started degrading the screen.
@amaral weird. the power button is definitely fine. I can't think what could have caused it - the most physically demanding usage it's seen in the past few days has been sitting in my pocket while cycling to work
@amaral which hopefully means that the warranty will still be valid tbh
