Fingerprint unlock doesn't work for first unlock after powerup/reboot

[NickJP]

I've noticed since the upgrade to Marshmallow that the fingerprint sensor on my Z5C doesn't work for the first unlock after the phone is powered on or restarted. It works fine for subsequent unlocks, but the first time I try to unlock the phone I press the power button once to turn on the screen, then touch it again to unlock, but instead of the screen unlocking I get the numeric pad to enter my pin appearing.

That is normal, first time after a reboot or if your xperia home crashes or is restarted, you will have to insert the PIN. No need to open a thread for this.
