IMEI number (15 digits)
The IMEI number is used to identify valid phones in the network. This number can also be used to block a
stolen phone. You may be required to give this number to Vertu Customer Service. To see your IMEI
number, from the home screen touch Apps> Settings>About phone>Status>IMEI
information.
Lock code (security code - minimum of 4 digits)
A lock code helps you protect your phone against unauthorised use. You can set your phone to ask for the
lock code that you define. Keep the code secret and in a safe place separate from your phone. If you forget
the code and your phone is locked, your phone will require service. Additional charges may apply, and all
the personal data in your phone may be deleted.
Master reset
A master reset returns your phone to the factory settings and erases all the data from the phone.
Toperform a master reset, from the home screen touch Apps> Settings>Backup&
reset>Factory data reset.
Warning: You may want to back up your data before performing a master reset.
Device protection
Your Constellation has Factory Reset Protection, which keeps your data safe when your phone is lost or
stolen. After you perform a master reset, you need to enter your Vertu account and/or Google account
details to use your phone.
Note: If you intend to give your phone to a new owner, then before you perform a master reset, touch
Apps> Settings>Accounts and remove your accounts.
Boot validation
Each time your phone is booted, the phone software is tested for authenticity. Most of the time this is
successful. However, two possible issues with authentication may occur. These are explained below.
Your device software has been unlocked for modification.
The authenticity of your device software cannot be verified.
If you receive either of these notifications and are unsure about what to do, contact Vertu Customer
Service for assistance.
