If you worry facial blindless means you’re missing something other readers aren’t, I don’t think that’s necessarily true.

I don’t have facial blindless and I rarely imagine character faces, it’s just too detailed. I picture their body shape (skinny, short, obese, etc) clothing when it’s a useful characterization (are they in a 3-piece, a trenchcoat, stillettos), and other unique features (dramatic hairstyles, amputations). Or in fantasy, their entirely alien shapes.

You’re asking a question that compares your experience to others, and I’d be wary of the implied expectation of “normal” in that context.

I’m holding a phone with 8GB RAM and it was the cheap version.
