to Morse Expert for Android

Hello, I installed the Morse Expert 1.13 an my android phone for learning cw. But without any activity, in complete silence around me, constantly cw-rubbish will be decoded.

My setting is an keyer with an sound generator with loudspeaker. Can I change the sensitivity from the mic of the phone or the sensitivity of the app?
