To increase protection, the application installation system uses digital signatures and
certificates for applications. Do not install the application if Application manager gives a
security warning during installation.
If you install an application that contains an update or repair to an existing application,
you can only restore the original application if you have the original application or a full
backup copy of the removed application. To restore the original application, first remove
the updated or repaired application and then install again from the original application or
the backup copy.
During installation, the phone checks the integrity of the application to be installed. The
phone shows information about the checks being carried out and you are given options
whether to continue or cancel the installation. Once the phone has checked the integrity
of the application, it is installed on your phone.
Installing applications
• Open Application manager, scroll to the application, and select Options→ Install to
start the installation.
• Alternatively, search the phone memory or the memory card, select the application, and
press to start the installation.
Some applications may give the option of partial installation allowing you to select the
particular components of an application that you want to install. If you are installing an
application without a digital signature or a certificate, the phone warns you of the risks.
Continue installation only if you are absolutely sure of the origin and contents of the
application
