For everyone who wants to remove the fingerprint animation, that greatly decreases the time to unlock the device, you just have to:
1 - Install the app Settings Database Editor
2 - Open the app
3 - Touch on "+ Add new setting"
4 - Type fod_animation_type
5 - Save changes
6 - Set 4 as value
7 - Save changes
8 - Done
This app does not require root.
To enable the animation again just remove that setting or edit the value (to 1 or 2 or even 3)
