Thank a lot for your help. Tell me please if you know more about this. I just want to know if it normal for 6s or do I need to change for another one.I noticed this same thing but I'm still trying to find if it's an issue. An iPhone 6 screen stays dead white on the edges when you look from an angle but my 6s and many others get darker, shaded edges if you look at them the same way.
I'm wondering if it's just a flaw with the backlight being too far from the panel or just a compromise for 3D Touch to work.
And to other people who don't get it and think the OP is crazy, you're not always right. Just because you don't see it doesn't mean it isn't there.
I did a quick comparison between an iPhone 6 to show the difference between the two. It exposes some of the flaws or compromises in the 6s backlight that make it have these weird angle effects on its edges. Mine even has LEDs bleeding through on the top if the angle is low enough. It looks perfectly normal at any natural angle though.Thank a lot for your help. Tell me please if you know more about this.
