Display Test

Display Test is an Android app designed to help you thoroughly test and diagnose the pixels on your device's screen. It enables you to display colors in immersive mode, allowing you to evaluate all pixels, including those typically hidden under the navigation and status bars. This app supports standard RGB testing, providing options to check red, green, blue, as well as white and black colors, effectively highlighting any pixel issues.

Comprehensive Color Testing

When using Display Test, ensure your screen is clean to avoid confusing dirty spots with dead pixels. It's recommended to run through all color options while scanning for any irregularly colored pixels. Additionally, test your screen at both maximum and low brightness levels. This can reveal possible backlight bleed or other imperfections.

Diagnosing Backlight Bleed

On devices with LCD displays, use the black color test at maximum brightness to check for uniform screen color. Any significant patches of lighter shades may indicate backlight bleeding, an issue that might require attention if it disrupts regular use. Display Test offers a practical solution for fullscreen testing, ensuring your device's display quality.
