What is profile for KindleFire and how to do profiling for Android with Profile Manager?

Using UE 4.4.0

I am trying to package the project for android (KindleFire). I need to set MobileContentScaleFactor=2.
First of we have a lot of different records in BaseDeviceProfiles.ini.
[Android DeviceProfile]
[Android_Low DeviceProfile]
[Android_Mid DeviceProfile]
[Android_High DeviceProfile]
and other (like [Android_Unrecognized DeviceProfile]) with reference to them.
How UE4 uses these profiles for Androids?

I created my own profile for KindleFire using Device Profile Editor. How to tell UE4 packaging system to use this profile on packaging process?
