Unreal Engine Android - Mic capture only work at first load of the app

I’ve Hawuii G8 with android 6

When I Request run-time permission for first time to access mic, I get mic input correctly, however, close the app and start it, no mic input.

also same apply when its fresh install and I enable the permission manually.

What i’m doing wrong?

I’ve found the problem, I did add the following to the DefaultEngine.ini

Once I removed it, everything runs smoothly and perfect.
