Its novel formulation is embedded with sensor calibration, where location estimations, fingerprint signals, and walking motion are jointly optimized with resultant consistent and correct model parameters. Fingerprint sensor calibration needed a30s LEVEL 2 (Screens, Batteries, Cameras, Daughterboards, ect) So yeah, just replaced the screen on my a50 and what do ya know, this warning appears (Fingerprint sensor calibration needed).
