Full Screen Test is an Android application developed by Sergiu Marsavela in the Utilities & Tools category. It is a free program that allows users to test their device's display for dead or stuck pixels. Many new devices come with this type of issue, which often goes unnoticed by users. This application fills the screen, including the on-screen navigation bar, with a single color at maximum brightness, making it easy for users to identify pixels that fail to display the intended color.

The application offers 9 available colors for testing:

• Red
• Green
• Blue
• Cyan
• Magenta
• Yellow
• Black (Key)
• Grey (50% of Red, 50% of Green, 50% of Blue)
• White (100% of All colors)

These sub-pixel colors are compatible with almost all types of screens. Full Screen Test does not contain any advertisements or require any unusual permissions, ensuring a smooth user experience.

Sergiu Marsavela has created a useful tool for users to quickly and easily identify any dead or stuck pixels on their device's display. With its simple interface and wide range of color options, Full Screen Test is a valuable utility for anyone concerned about the quality of their device's screen.
