[Q] Dead pixels
I bought my s4 off amazon and it has 5 dead pixels in upper left hand corner, how can i get a clear picture of the pixels to show the seller the problem? I've tried taking picture with my s2 but its hard to see dead pixels through picture cause i reflect on the screen. The dead pixels only appear on dark black screen colors. How can i get a clear picture of dead pixels on black screen color w/o high tech expensive camera?
