Dust affinity for phone screens

[Chintan Gohel]

Every time I take out my phone from my pocket, there's a lot of dust particles stuck on it and I have to wipe it regularly. Are the phone screens made such that dust just adheres to it or is it to do with something else?
I've seen this with lumia 1020 (amoled screen) and lumia 540 (lcd screen)

I also see this on my surface 3 but not as much

I used to do that but for work purposes I had to get a holster clip for it. It always got hot in my pocket, and heat kills battery life. Plus the lint and stuff gets in the small speakers and earpiece holes.

lint was the word I was looking for
For my old 1020, I had a flap cover case for it, so the lint was at a minimum, wiping was needed once in a while, like a month, just to remove the fingerprint smudges
