Turning use of lock code on my tablet on or off
If you want to prevent others from accessing the contents of your tablet (such as pictures and messages), you need to turn on the lock code. Once done, it needs to be keyed in every time you turn on your tablet.
Please note: the lock code doesn't protect your tablet against unauthorised use. Your SIM is protected by turning on your PIN.
