Nano-texture glass is etched glass that scatters light to significantly reduce glare without washed-out colours. Apple offers Nano-texture glass as display option for iPad Pros and MacBook Pros, but not for iPhones.
So, I had matte anti-glare screen protector applied on my iPhone 12 and iPhone 16 Plus by mobile telecommunications service provider Vidéotron. The ultra-thin bezel (border around the screen) of iPhone 16 Plus is significantly thinner than that of iPhone 12. The result is that iPhone 16 Plus's case interferes with the screen protector, forming a plurality of bubbles.
