InjuredPixels

InjuredPixels is an app that lets you check to see if there are any dead pixels on your screen. You know, the ones that have gone black (or any other color) and don't change no matter what you do.

The app is especially useful for making sure your recently purchased smartphone is in perfect condition. All you have to do is run it (there's no need to install anything) and select the different colors using the volume buttons or tapping on each color.

Red, green, back, blue, white ... InjuredPixels checks all the basic colors so you can see clearly if there are any injured or dead pixels. You can also set custom colors using the options in the upper right corner of the screen.

It's important to mention that InjuredPixels doesn't actually let you repair any damaged pixels you find, it only helps you find them. That said, it's an effective an easy-to-use tool that does exactly what it promises.
