I'm used to a schema to unlock my phone.
Since the XR 4.0, the lockscreen schema is at the bottom of the screen. It makes it easier to use but it's over the fingerprint sensor.
I've tried to test a fingerprint in more of the schema but despite one fingerprint is registered, the lockscreen doesn't allow to unlock by FP, probably because the icon can't be displayed as the schema takes its place.
The schema at the bottom of the screen is welcomed while no other unlock way is set.
But when a fingerprint is set in more, the schema should be moved higher enough to allow the FOD to be displayed as well.
EDIT / UPDATE:
The FOD icon appears after I lock my phone while an app is running in foreground.
If I lock it without any foreground app, from the launcher, only the schema is displayed as unlock method.
A good point: when it's displayed, the FOD works well, almost a miracle as it never worked on my phone before the XR 5.0 and I've never managed to find out what caused this issue.
EDIT / UPDATE 2:
I've figured out what went wrong.
Locking the phone can be done through two different ways:
- Accessibility: Locks the device like the power button was pressed. Requires Android Pie.
- Device administrator: Locking ompletely the device requires a PIN code. This doesn't allow to unlock by fingerprint.
My mistake was to lock my phone differently depending on the app running in foreground:
- Without any app, only the launcher, I used a Automate widget with only the block "Lock device", which locked obviously as administrator and ended up hiding the FOD.
- With any app in foreground, I used a gesture of Vivid Navigation Gestures, which locked through Accessibility obviously, allowing the FOD to unlock.
I've solved this issue by replacing my Automate widget by a Nova Action widget which locks though accessibility and therefore allows the FOD
