Learn what to do if you see certificate error when signing in to Norton app on Android 4.x or earlier

On Android 4.x or earlier, you may see a certificate error when you sign in to Norton apps such as Norton Family or Norton Mobile Security. This error can occur due to latest Norton certificates that are not being supported by Android 4.x or earlier versions.

To fix this problem, we recommend that you upgrade your Android OS on your device to a supported version.
