Store description excerpt
OLED Screen Tester fills your screen with pure colours and patterns so you can diagnose display issues on any Android device in seconds. HOW IT WORKS Launch the app, pick a test scenario, and tap the screen to cycle through colours. The display automatically goes fullscreen and brightness jumps to maximum — so problems are impossible to miss. Tap the back gesture or the close button to exit; brightness resets automatically. TEST SCENARIOS • All Colours — sweeps through hundreds of hues • Grayscale — 10-step gradient from black to white • Black & White — pure #000000 and #FFFFFF only • RGB Primary — full-screen red, green, blue • CMY Secondary — cyan, magenta, yellow • Dead Pixel Check — solid colours to reveal stuck or dead pixels • Line Pattern — fine horizontal and vertical grid lines • All Tests — runs every scenario in sequence WHAT YOU CAN CHECK • Dead or stuck pixels (a pixel that never changes colour) • Screen burn-in or image retention (a ghost of a previous image) • Colour accuracy and tint uniformity • Backlight bleed on LCD panels • Brightness uniformity across the display PERMISSIONS WRITE_SETTINGS — used only to set brightness to maximum during a test. Brightness is restored automatically when you exit. SUPPORTED LANGUAGES English, Deutsch, Français, Español, Italiano, Português, Русский, 日本語, 中文(简体), Türkçe
