*Fingerprint Unlock Tests. What I found.
A. Display OFF by Android only. (Screen Sleep time out or by short push power button )
Komoot Android screen time out > Display OFF > Fingerprint unlock > Display ON (complete unlock)
Locus Android screen time out > Display OFF > Fingerprint unlock > Display ON (complete unlock)
B. Display OFF by a Locus map Pro action. (Locus Device Administrator /Locus Map as service )
(Settings > Controlling > Display > Screen ON/OFF control)
When Locus map Pro triggers a Display OFF, than Fingerprint unlock asks PIN.
By the actual Locus map Pro version.
1. Display OFF > Push Power button > Display ON. (Partial unlock, Locus map, no keyboard)
2. Display OFF > Proximity Wave Unlock > Display ON. (Partial unlock, Locus map, no keyboard)
3. Display OFF > Fingerprint Unlock > Phone asks PIN > Tap Return Button > Display ON. (Partial unlock, Locus map, no keyboard)
4. Display OFF > Fingerprint Unlock > Phone asks PIN > Enter PIN > Display ON > (Complete unlock, keyboard activ)
Enter PIN if you need other Android app, e.g the keyboard app.
