Key Features
  • 4-in-1 Design: Contains standard calibration targets (such as black, flesh-colored, and pattern surfaces) required by factory calibration software.
  • Wide Compatibility: Works with major Android brands including Huawei, Xiaomi, OPPO, VIVO, and OnePlus.
  • No Disassembly Needed: Calibrates directly from the top of the newly installed screen without taking the device apart again.
  • High Success Rate: Delivers a high recognition rate to correct “fingerprint sensor calibration needed” or input errors.

How It Works
  1. Software Access: The technician boots the phone into its factory test mode, Kernel menu (CIT), or uses brand-specific service software to start the “Optical Calibration” test.
  2. Target Placement: When prompted by the screen, the technician places the matching side of the RL-071B block directly over the under-display sensor area.
  3. Multi-Step Testing: The software takes reference readings against the calibrator’s precise color profiles (such as total dark/black and flesh tones) to clear out sensor alignment deviations.
