Since both companies Xtrons and Joying don't care at all about their DAB+ app extremely stuttering when running in the background, I started to patch their versions of the DAB+ app.
I gave the detailed instructions how to change the code of the DAB+ App to Joying. They appreciated my effort and promised to give this info to the original developers of the App. They did not want (or cannot) give me the contacts of the original developer/company responsible for the DAB+ App (com.ex.dabplayer.pad).
However, also their recent new versions of the DAB+ App do not bring with them the solution for the stuttering issue when in background. So I will continue to patch it...
Current latest version:
