David Spark on Nano texture displays:
I can’t help but wonder if Apple will eventually bring Nano-texture to the iPhone. Given how often people use their phones in direct sunlight, it could help. Regardless, for those who need a high-end, anti-reflective display, Apple’s Nano-texture glass is the best I’ve seen, and far superior to any screen treatment or film I’ve tried.
If nano texture display ever come to the iPhone, I would buy it in a heartbeat even if I didn’t for my M4 iPad Pro (too expansive).
