tfouto yes I have, now I got it with matte screen protector 3MK not skinomi (shipping from US is more expensive that protector himself maybe I will try later). Tried this fancy ZAGG Bluelight filter Glass and thanks God they made me refund - very bad head pain with it was worst then without and I know if I have this at beginning it will last so not worked for me , also tried some other cheap glass but this matte 3mk seems to be the best, For some time I used this with white point at 90 - 95% and brightness at 50% - less flicker, but after maybe a week I found to be better use without this option and around one week now I'm using it at 5 - 10% brightness some time more. Are days that don't fell nothing when using XS, but like today used for around 8 hours MacBook Air and when I use XS I feel discomfort but actually I had the same with iPhone 6, still giving it a chance. My wife's XR seem to be ok with regular glass no matte protector but I didn't used this for long time and XS is much better with camera, size and I like it better so I'm stick for now with it.
