Screen lock not secured
To secure your device with a screen lock code, password, PIN, or pattern, navigate to Android settings > Security & Privacy > Device unlock, and select one of the available options. Most Android devices offer Swipe, Face unlock, Face and voice, Fingerprint, Pattern, PIN, or Password.
If someone tries to unlock your device using an incorrect code, ESET Anti-Theft will notify you about the suspicious activity by means of a notification on your device.
