title: Does anyone know how to find dead pixels on a phone screen automatically?
body: <p>does anyone know how a program can find dead pixels on a phone screen?</p>
  <p>I found a lot of dead pixel finding tools and all of their implementations looks similar. It's showing a single-color screen, such as red, green, blue, white and black. Then, we need to check if there's any dots with different color (which is dead pixels) manually.</p>
  <p>Is it possible to find the dead pixels automatically?</p>
