==================================
KEY DIAGNOSTIC MODULES
==================================

TOUCH TESTS:
• Touch Grid Test:
Divide your display into a full-screen grid. Swipe across the glass to verify if every sector registers touch input properly. Uncovered zones highlight potential touch issues.
• Multi-Touch Test:
Detect simultaneous touch points. Verify your device digitizer capacity, track individual pointer IDs, and monitor real-time X/Y coordinates.
• Touch Trail Test:
Draw continuous paths across the panel to detect broken line trajectories, jitter, sudden coordinate drops, or dead edges.
• Touch Point Crosshair:
Inspect precise touch coordinates, active pointer IDs, and pressure levels (where hardware-supported) with real-time crosshair visualization.
• Potential Ghost Touch Observation:
A 30-second timed observation test. Place your device on a flat surface without touching the screen to monitor and record unexpected touch events.
• Edge Sensitivity Test:
Verify responsiveness along the glass perimeter near physical bezels and curved borders.

DISPLAY & COLOR TESTS:
• Solid Color Test:
Full-screen solid colors (White, Black, Red, Green, Blue, Yellow, Cyan, Magenta, Neutral Gray) to check for backlight bleed, tinting, and color uniformity.
• Dead Pixel Inspection:
Visual inspection screens designed to help you spot stuck, dead, or hot pixels that remain discolored against solid backgrounds.
• Gradient Quality Test:
Smooth RGB, grayscale, and primary color gradients to observe color transitions, banding, and gamma fidelity.
• OLED Burn-in & Retention Test:
Specialized inspection patterns (neutral gray and high-wear silhouettes) to observe permanent burn-in or temporary image retention.

DEVICE & SCREEN INFORMATION:
• Display Specifications:
Instantly view physical screen resolution, logical dimensions, pixel ratio, screen density, orientation, refresh rate (Hz), and OS version.

GUIDED FULL DIAGNOSTIC FLOW:
• Run a streamlined 8-step guided test covering touch and display modules in under two minutes.
• Receive an aggregated Screen Health summary report.

TEST HISTORY & REPORT SHARING:
• Save diagnostic reports locally on your device.
• Export and share formatted certificates to document screen condition before buying or selling a used phone.
