Hey, I am Tech Riddhipratim, developer of Appy Pixel Tester

With Appy Pixel Tester, you can test your smartphone's display for dead and stuck pixels.

A dead pixel is a stuck point or several points of the matrix screen, which does not properly reflect the color. Sometimes they are almost invisible, and you can be the owner of them without even noticing it.

Appy Pixel Tester makes it easier to find your phone's display/pixel issues by providing unlimited backgrounds to scan. It comes with a cool and clean and smooth user interface. And everything is available for free.

Appy Pixel Tester provides two types of scans:
1. Universal Scan: It provides unlimited backgrounds to test display/pixel. You can customize the color you want and its opacity from the two different color palettes the app provides, HSV and RGB color palettes.

2. Earth San: It is limited to a few colors for those who have less time and want quick scans. The app provides a Material color palette for that.

Appy Pixel Tester will be capable of changing brightness in-app and fix dead pixels in future updates. So stay tuned.

Enjoy!
