Displa - Your Screen

Have you ever bought a used phone, only to later notice an annoying spot on the screen that just won't go away? Displa won't let you be fooled.
This app turns your smartphone into a professional display defect detector. With just a few taps, you can check every single pixel on your screen. Simply switch through vibrant colors and scan the surface — dead pixels won't be able to hide. They'll stay black or stuck on one color, and you'll spot them
