Screen test & Display Info

Screen Test & Info is a comprehensive display tester, hardware diagnostic checker, and GPU benchmark analyzer for Android devices. Seamlessly evaluate your mobile panel for stuck pixels, evaluate screen burn-in uniformity, calculate graphic rendering performance, and extract detailed technical specifications regarding your hardware configuration.

Whether you are evaluating a used smartphone before purchasing or troubleshooting touch accuracy issues after a screen replacement, this diagnostic tool provides clear hardware clarity.

📱 Detailed display specification readout
Gather essential technical metrics regarding your display panel:
• Resolution configurations and display panel types (FHD+, QHD, 4K layouts).
• Screen dimensions in inches alongside precise aspect ratios.
• Pixel density reporting calibrated in DPI and PPI values.
• Hardware refresh rate monitoring across all supported operational modes.
• High dynamic range detection supporting HDR10, HDR10+, Dolby Vision, and HLG.
• Brightness range boundaries reading maximum and minimum luminance levels.
• Display cutout geometry, corner radius paths, and active color gamut profiles.
• Form-factor structural adaptation including foldable posture and hinge tracking.

🎨 Visual screen evaluation tests
Identify panel irregularities before they impact your daily viewing experience:
• Gradient evaluation matrix: Detect transition imbalances and color banding anomalies.
• Dead pixel and burn-in checker: Isolate stuck sub-pixels and display ghosting using full-screen solid color cycles.
• Grayscale uniformity check: Verify overall gamma accuracy and color balanced reproduction.
• Checkerboard alignment test: Evaluate subpixel rendering sharpness across eight structural layouts.

🚀 Graphics performance and benchmark suite
Evaluate frame rate stability and rendering consistency under standard graphical loads:
• Refresh rate Hz tester: Review visual motion smoothness across multiple speed tiers using a live frame-per-second (FPS) counter.
• Pixel persistence checker: Track screen ghosting artifacts using a multi-speed moving object animation test.
• GPU 2D graphics benchmark: Evaluate particle rendering stability tracking minimum, average, and maximum frame rates.
• GPU 3D graphics benchmark: Analyze fractal rendering engine consistency using five scalable test complexity tiers.

⚙️ Live hardware diagnostics at a glance
• Device identity mapping: Review marketing product identifiers rather than simple raw model codes.
• Chipset analyzer: View CPU architecture details, manufacturer paths, core layout tiers, and operational frequencies.
• Core load updates: Monitor active multi-core processing loads using real-time animated tracking indicators.
• Memory resources: Track active RAM consumption metrics, available memory pools, and internal storage capacities.
• Battery health telemetry: Monitor current voltage levels, temperature readings, charging statuses, and estimated full-charge capacity baselines derived from active system usage stats.

👆 Comprehensive multi-touch tester
• Touch precision diagnostic: Draw on a structured screen grid pattern to verify digitizer accuracy across every corner.
• Multi-touch point evaluator: Verify total simultaneous finger tracking support using unique color-coded contact markers.
