I'm on an iPhone 5S, and I'm just wondering if this is a normal thing or not. Basically, when I scroll quite quickly on, say, Twitter, for instance, I find that the text blurs slightly. I'm not sure if "blur" is the right word to use for this, but it does something to make it less readable. Is it meant to be completely solid and smooth when scrolling? Or is this thing I am seeing, something that's normal? Also, on another note, is it normal to be able to see the screen's pixels? Because, I can. They're tiny, but I can see them when looking closely.
