It's far trickier than I imagined. Is not obvious yet the effect can be quite dramatic if done properly. I tried to explore circular polarization, but couldn't make it small enough to integrate into the phone.
Wow!!
Well, I look at it more carefully again, and I found that it is not really a "polarizer", but instead it could just rotate polarized light! Yet, it is interesting enough to me
