My wife and I have identical Samsung GT-I5510M phones running Andriod 2.2.2.
The current version of Security on Play Store is for 2.3 or greater. These are older phones and 2.2.2 is the latest version. My phone had the Free Norton Security loaded before the change to the newer version, so I was able to get all the features by putting in my current Key Code.
Does anyone know how I could get the version of Security that I need. 3.9.1.2245?
