Hello, guys! I have one very thin spec of dust under the screen near to the home button. This is my second replacement- first had very uneven backlight and a dead pixel. This one is perfect as white ballance and display in overall, but came with this piece of dust and two very thin inner diagonal scratches under the glass of the screen. Both problems are hard to be noticed exept you are looking carefully straight for them. I bought another white 4S to make a choice between my second black replacement and the white one, but the white had this terible "interlace scan lines" problem and very washed display, so I took it back imediatelly. Should I bother to take the one with this cosmetic issues back and to risk of getting another one, which may have even worse problems like dead pixels, uneven whites, scan lines... What you would do?
