Problem with FL Studio 20?

I got FL Studio 20 and wanted to push the track over to my phone with a piano roll over it, but you only hear the piano roll very softly. Is there any reason, because on Windows Music Player it works just fine on the phone (Huawei P8 lite), even with my friend it does not work and it has an iPhone X.

Then you have to make it louder?
