Store description excerpt
Inspect your Android display visually with solid colors and a precise high-contrast grid. SEVEN VISUAL PATTERNS • White • Black • Red • Green • Blue • Gray • Pixel grid Preview each pattern in the app, then start the distraction-free full-screen test. Tap anywhere to move to the next pattern. Long-press or use Back to return to the dashboard. WHAT TO LOOK FOR Clean the screen first and reduce room glare. View each solid color at a comfortable brightness and look for a tiny area that remains dark, unusually bright, or a different color. Use the grid to inspect obvious spacing and line consistency across the panel. LOCAL AND PERMISSION-LIGHT The visual test does not need camera, screenshot, microphone, location, storage, an account, or cloud access. It simply draws colors and lines on the display. The app includes advertising outside the full-screen pattern area; advertising-related device identifiers are disclosed separately in Google Play Data safety. HONEST LIMITS This app is a general visual inspection aid. It does not repair dead or stuck pixels, remove burn-in, measure color accuracy, test touch response, identify the cause of a defect, or certify a display for professional use. Some defects may be too small, intermittent, brightness-dependent, or hidden by scaling and panel characteristics. Avoid staring at very bright screens for long periods. Use a comfortable brightness and stop if you feel discomfort. If a display problem affects safe use, seek qualified device support. Use Dead Pixel Screen Test when checking a new phone or tablet, comparing a repaired display, or documenting a visible panel issue before requesting service.
