Have you been able to notice improved screen readability compared to the privacy screen protector originally offered? I’d be willing to sacrifice the “can’t read screen from an angle” feature if I could get better readability in bright conditions. On the ski lift today (in sunny conditions with lots of white all around), I had challenges seeing the “take a photo” button in the camera app.
I was actually concerned that I would have a problem with brightness with the security screen so I never installed it. So, I can’t really comment on that. Sorry.
Generally speaking, a non-privacy screen protector will have a better readability than a privacy screen protector. While the privacy screen protectors improved over the years, they are not going to be 100% clear when front facing.
