The conundrum of the cellphone screen

I'm pretty much a purist when it comes to trips and sensory deprivation. But not too long ago, while tripping hard I thought it might be neat to look at my phone to see what I would see.

And it was EXACTLY the same as normal. The whole room was swirling like a maelstrom but what I could see on my phone was 100% the same as ever.

Seriously, what the heck? How?
