Yeah that's true too. There hasn't been conclusive proof, but if you're senstive to radiation or em waves like me, you don't need any one to prove anything. My body lets me know
I went through a period a couple of years ago where I became really concerned about smartphones emitting harmful radiation. But the thing is, even after a lot of research on the internet, I couldn't decide if this was actually the case. Some studies day it didn't matter, others blame devices for everything. I too have started not really caring about radiation now and all I have is a screen protector.
