# Test and validate Before deploying sensors in production, you must calibrate them for accuracy, verify that they’re correctly configured, and validate driver behavior under real operating conditions. This section provides the complete post-development validation workflow from calibration through stress testing and troubleshooting. Calibrate sensors Factory and runtime calibration procedures for accelerometer, gyroscope, magnetometer, proximity, and ambient light sensors. Calibration updates the sensor registry and increments the ver field to confirm a successful write. https://docs.qualcomm.com/doc/80-80022-7/topic/calibrate.html#calibrate Verify sensors Use ssc_sensor_info to list all QSH-supported sensors and inspect their attributes. Confirms that the sensor registry is correctly parsed and that QSH is operational on the device. https://docs.qualcomm.com/doc/80-80022-7/topic/verify.html#verify Troubleshoot sensors Diagnose and resolve the three most common sensor failures: ssc_sensor_info unable to list sensors (registry parse failure), SUID lookup failures (sensor not in registry), and sensor listed but no data received (application code issue). https://docs.qualcomm.com/doc/80-80022-7/topic/test_troubleshoot.html#debug Sensor testing tools All testing and diagnostic tools in one place: ssc_sensor_info for sensor listing, ssc_drva_test for driver acceptance testing, see_workhorse for stress testing, Hexagon DSP toolchain for the build environment, and QXDM Professional for aDSP-side diagnostic logging. https://docs.qualcomm.com/doc/80-80022-7/topic/test_tools.html#test-tools Last Published: May 07, 2026 [Previous Topic Qualcomm® sensing hub APIs](https://docs.qualcomm.com/bundle/publicresource/80-80022-7/topics/qsh_api_reference.md) [Next Topic Calibrate sensors](https://docs.qualcomm.com/bundle/publicresource/80-80022-7/topics/calibrate.md)
