Automated Screen Damage Detection for Smartphones

Seasia Infotech partnered with a leading refurbished phone enterprise to design an AI-based mobile screen inspection for refurbishment that streamlines quality control for warehouses and repair centers. The client aimed to replace error-prone manual inspections with a mobile screen grading system powered by computer vision, multi-angle CCD imaging, and deep learning models.

The goal: achieve 90%+ accurate phone screen crack detection, reduce operational costs, and scale mobile device quality control across thousands of devices.

INDUSTRY
Insurance
PROJECT DURATION
4–6 Months

The refurbished device market suffers from delays and inconsistencies in manual phone repair inspection systems. Inspectors often miss micro-cracks or grade severity inconsistently, leading to disputes, returns, and slow refurbishment cycles.

Seasia Infotech developed a deep learning screen damage detection solution designed as a scalable automated phone screen crack detection system for warehouses. The system combines multi-angle phone inspection systems, RGB → HSI transformations, and CNN-based object detection systems for smartphone screen defects to accurately classify cracks into minor, moderate, and severe categories.  

Project Scope & Challenges

The client needed a mobile device quality control solution to automate screen defect detection across different models and volumes, overcoming manual inspection limits.

Subtle Damage
  • Cracks visible only at certain angles
Model Variability
  • Different sizes and materials
High Throughput
  • Inspecting thousands daily
Manual Limitations
  • Inconsistent and costly checks
