My phone was reset. How can I restore Mobile Security?
After a system reflashing, try to update the application. If the update is not possible, you may have to download the latest installation package (*.apk) again from Google Play or from http://www.f-secure.com/en/web/home_global/protection/mobile-security/download.
After the installation you don't need to enter the subscription key.
Should you have any problems, please create a support request.
