System and method for detection of mobile device fault conditions

This invention describes a way for a mobile phone to check itself for screen damage like cracks or scratches. It works by installing a special app that tells the user to place the phone facing a mirror. The app then adjusts the phone's screen brightness and camera settings, using ambient light information, to take the best possible picture of its own display reflected in the mirror.

Why it matters: Filed before advanced on-device image processing and machine learning. Modern phone cameras and computational photography make the precise calibration and defect detection much more accurate.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, image processing, calibration algorithms
