Hello Costas,
I think I have misread the original post. The dense_cloud_max_neighbors tweak in 1.7 version should be modified to BuildDenseCloud/max_neighbors and it doesn't depend on the new/old depth maps generation algorithm (by default NEW depth maps are generated).
Do you have a possibility to update to APK version 1.7.1? I suggest to do that, as dense cloud noise filtering has been improved in this version.
