Protect your phone
Learn how to protect your phone, and keep your data secure.
Set your phone to lock automatically
Want to protect your phone against unauthorised use? Define a security code, and set your phone to lock itself automatically when you're not using it.
Select and Security > Device lock .
Select Security code, and enter a security code (at least 5 characters). You can use numbers, symbols, and upper and lower case letters.
Keep the security code secret and in a safe place separate from your phone. If you forget the security code, and cannot recover it, your personal data is deleted before you can use the phone again. If you've set the number of times you can enter the wrong security code, your phone deletes your data and resets itself back to original settings after the last try. If you haven't limited the number of times, your phone requires service before you can use it again.
Select Autolock, and define the length of time after which the phone is locked automatically.
Unlock your phone
Press the power key, and swipe from the outside of the screen onto the screen. You can swipe from any direction.
Enter the security code, and select OK.
You can also tap the screen twice, and swipe from the outside of the screen onto the screen.
When you update your phone software using the Nokia Software Updater PC app, the language of your on-screen keyboard is set back to the default language. If your security code includes characters that are not part of this on-screen keyboard, select , then swipe left or right across the keyboard to change the language of the on-screen keyboard to the one you used when creating the security code.
If you have defined a trusted person, if you ever forget your security code, you can send them the code in a text message. Select Device lock > Trusted person > Select trusted person and a contact from the list. If the trusted person's phone number changes in the contacts list, you need to change it manually
Phone lock settings
You can define a security code and set your phone to automatically lock itself when you're not using it.
Some services, such as Mail for Exchange, may require that you define a security code for your phone. Depending on administrator security requirements, also your phone lock settings may be changed, such as Autolock and Number of tries.
Select and Security > Device lock , and from the following:
Autolock — Set the length of time before the phone locks automatically.
Security code — Change the security code. To use the phone lock, you need to define a security code.
Number of tries — Set a limit for incorrect security code attempts. After the limit is reached, the phone is reset to original settings and all user data is deleted.
Trusted person — Set one of your contacts as a trusted person. If you have defined a trusted person, if you ever forget your security code, you can send the code to the trusted person in a text message. After entering the incorrect security code, select Recover, and follow the displayed instructions. If your trusted person's phone number changes in the contact list, you need to update it here manually.
Remote security features — Set up remote lock. If you lose your phone, you can remotely lock it or delete the data saved on it.
Hide private information from your notifications
Don't want to let other people see who has called you? When you have missed a call or received a message, a notification is displayed on the lock screen. You can define how much information is displayed.
Select and Notifications > Notifications , and activate or deactivate Hide private information.
When Hide private information is activated, only the number of received messages and missed calls is displayed.
When Hide private information is not activated, when you have received a message or missed a call, the following information is displayed:
The name of the person who has tried to call you
The sender of the message you have received
Part of the message content
See Lock the keys and screen .
Develop your own applications
You can create your own applications for the phone using an applicable software development kit (SDK).
You need to activate developer mode on the phone to be able to use it as a target for application development. Developer mode enables connectivity between the development host and the phone, and provides a few additional tools on the phone.
Select and Security > Developer mode , and activate Developer mode.
It is recommended that you do not activate developer mode, unless you intend to develop applications for the phone. Activating developer mode does not expose the phone to security risks, but you may accidentally delete important system files.
