Android 4.x support for F-Secure SAFE, as well as support for earlier Android 4.x operating system versions has come to an end in February, 2018. The decision to discontinue Android 4.x support follows Google's own decision to discontinue its support for the last Android version in the 4.x series, Android 4.4 (KitKat), which it no longer provides security patches for.
End of support means that if our security product is installed on an Android 4.x operating system, we cannot guarantee the protection on that device. As Android 4.x support for F-Secure SAFE has ended, this means that -- if your Android device is running an Android 4.x version -- your device will no longer receive the necessary security updates and may be more open to security vulnerabilities as a result.
To stay safe, we highly recommend that you upgrade your Android operating system to an Android version that receives security updates. The most recent operating system version always provides the best protection technologies and is fully maintained by the vendor, receiving timely security updates and improvements.
If you have a valid license for our security product and you upgrade your device operating system, your existing license is still valid for the supported platforms.
