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.
