The screen lock protects the Android smartphone from access by unauthorized persons, preventing both operation and access to the memory or personal data.
Android offers unlock methods such as the pattern, PIN or password, depending on the device model.
Note: The screen lock does not protect the SIM card; in case of loss, the SIM card can be used if no SIM lock is enabled.
