Simple Screen Tester

Simple Screen Tester helps you to detect all dead pixels on your mobile device screen. Mobile device screens contain only three types of pixels: red, green and blue. Any other color is just a combination of these three colors. This application provides a separate page for each of the base colors so you can check each type of the pixels separately. Look at the screen carefully to notice black or white dots on the red, green or blue color filled screen. It is also advised to clean the screen with a soft cloth before the test so that the dust particles and fingerprints will not interfere the test.
