Huawei P9 fingerprint sensor

[AC Question]

Anyone notice that if you have usb cable plugged into the Huawei P9 and when you try to unlock the lock using the fingerprint sensor, it is not that accurate and very difficult to read your finger. However if your USB cable are not plugged into the phone, unlocking the phone with the fingerprint sensor is a breeze.

Anyone came across this issues?

And from my time with the P9, I haven't really ran into such an issue. Weird.
