How to detect if physical back key exists?

[mikkori]

Is there some good way to detect if the device has a physical back key (like in Asha 501) ?
One thing I have come up is to check that the version of Nokia UI API is 1.7 but is there some more "official" way to do this?

Does this help?

Yes, use system property - "com.nokia.keyboard.type"

String keyboardType = System.getProperty("com.nokia.keyboard.type");
if (keyboardType.equals("OnekeyBack")) --> // you have physical BackKey
