  • Turn up volume on (on older tablets)

15. Smart lock function

Starting with Android 5.0, the system has a Smart Lock function that allows you to turn off the screen lock in certain situations.

Depending on the manufacturer of the device, as well as the version of Android, there are different options for unlocking with Smart Lock, such as voice recognition, face recognition and others.

Of course, Smart Lock is a convenient feature that simplifies the use of a mobile device. But thanks to it, attackers can gain access to personal information stored in a smartphone. For example, if you specify the office as a safe place and leave the phone in the workplace, anyone can unlock it. Therefore, correctly configure Smart Lock, but rather think a few times before turning on this feature.
