Frequently Asked Questions

• Is it necessary to reprogram the system after replacing the reader on the Huawei P30 Lite?
  Software calibration is not necessary; after physical installation and correct connection to the mainboard, biometric recognition becomes active in the system immediately.
• Does the sensor work if the flex is creased or bent excessively?
  Physical damage to the internal conductive tracks of the flex prevents the transmission of biometric data, requiring complete replacement of the assembly.
