Screen test & Display Info

Display tester, dead pixel detector, GPU benchmark & hardware info for Android

Screen Test & Info is a complete screen tester, hardware diagnostic, and GPU benchmark app for Android. Check your display for dead pixels, test screen burn-in, measure GPU performance, and get detailed specs about your phone — all in one app.

📱 Display Information

Everything you need to know about your screen:
• Screen resolution and display type (FHD+, QHD, 4K)
• Screen size in inches and aspect ratio
• Pixel density (DPI and PPI)
• Refresh rate — all available modes
• HDR support detection (HDR10, HDR10+, Dolby Vision, HLG)
• Brightness range (max and min luminance)
• Display cutout and corner radius details
• Color gamut information
• Foldable phone detection with hinge position and posture

🎨 Screen Tests

Find display problems before they get worse:
• Gradient Test — detect color banding issues
• Dead Pixel & Burn-in Test — find dead pixels, stuck pixels, and screen burn-in with full-screen color patterns
• Grayscale Test — check gamma accuracy and grayscale uniformity
• Checkerboard Test — verify pixel sharpness and subpixel alignment with 8 different test patterns

🚀 GPU Benchmark & Performance

Stress test your phone and measure real performance:
• Refresh Rate Test — smooth motion test at multiple speeds with live FPS counter
• Motion Blur Test — detect ghosting and pixel persistence with a UFO-style test at 5 different speeds
• GPU 2D Benchmark — particle stress test with up to 12,000 moving objects. Shows Min, Avg, Max FPS and frame time.
• GPU 3D Benchmark — fractal rendering stress test that pushes your GPU to the limit. 5 difficulty levels from Light to Insane.

⚙️ Hardware Information

Live device diagnostics at a glance:
• Phone model — shows the real marketing name, not just a model code
• Processor — chip name, manufacturer, number of cores, max frequency
• CPU core layout — detects Performance and Efficiency cores automatically
• Live CPU load — per-core frequency with animated bars updated every second
• RAM usage — used, total, and available memory
• Storage — internal storage breakdown
• Battery health — level, status, temperature, voltage, and estimated full-charge capacity that reflects actual battery wear over time
• System info — kernel version, security patch, build number

👆 Touch Screen Test

Make sure your touch screen works perfectly:
• Touch Accuracy Test — draw on a grid to verify touch precision across the entire screen
• Multi-Touch Test — test how many simultaneous touch points your phone supports with color-coded finger tracking
