Hello, I picked up a brand new 5S today. I originally had the 5C but didn't really like it. The 5S is an amazing device and feels much better to use. It came with 7.0.3 preinstalled. The 5C I bought on Tuesday came with 7.0.2. My 5S shows 0* while on a flat surface, the power button does make a tiny bit of noise if I really shake it and the sound isn't picked up while video recording. However, the screen is what's bothering me so I have some questions. 1. There seems to be a very faint flicker but definitely does not bother me in normal use. There also seems to be faint lines going across the screen. Not horizontally but diagonally, again this is very faint and only really noticeable if looking real close. Is this normal for the 5S screen? Either way it doesn't really bother me but just wanted to ask. 2. There seems to be a lot of dust under the screen but again not really noticeable unless brightness is up full and I'm looking closely. However, there is one dot which seems to be more noticeable. I can't tell if it's black or red. You can't really see it straight on but at an angle. Is this a dead pixel or just dust? 3. At the top of the screen there seems to be a yellow tint. I know the iPhone's LED backlight is up there and sometimes causes uneven lighting but this is like an even dark yellow tint. Is this normal? I'm not sure if it's just my eyes or not. Apart from these 3 things my 5S is perfect. I love the weigh/feel of it, it's much smoother than the 5C and it runs very fast.
