What is the lockdown mode on Galaxy S9 and S9+ with Android Pie update?
If enabled, Galaxy S9 and S9+ offer many ways to unlock the phone.
In addition to PIN/password/pattern, you can also unlock Galaxy S9 and S9+ using:
- Fingerprints.
- Iris.
- Face.
- Trusted devices, trusted places, trusted faces, and matched voices through the smart lock.
All these additional unlock methods are provided for your convenience. Many Galaxy S9 and S9+ owners enjoy these fast unlock methods.
However, in some special situations, for example, someone attempts to force you to unlock the phone to get your data, you may try to disable these unlock methods temporally (and quickly), then type the wrong password/PIN a few times so that you have to wait longer and longer to try again.
When the lockdown mode is enabled, notifications will not be shown on the Galaxy S9 lock screen.
