Thank you Paul for your kind reply.
Not sure if I get the first point right though. You mean apps need permission to preinstall but you don't have it right? And never will have?
I don't mind Android File Transfer but let's face it, external disc mode is far more convenient. I know that most DAPs need AFT on Mac but I had X7 (also Android device) and it worked like external disc which was nice. On the other hand AK DAPs need AFT as well. Strange...
Hope WiFi updates will be here soon.
I'm gonna buy DX200 anyway as soon as it hits my country
