Ok, I thought that the bug of Spotify struggling when I send ou receive messages was only in this case (messages of WhatsApp), but it happens with any sound, YouTube, Spotify, WhatsApp audios (when I get any notification the sound playing just struggle a little bit and then get's normal again). And another bug is that now there is sometimes when I try to open an app that I blocked with my digital and it just doesn't work, don't open, nothing happen, and there isn't any problem with my digital "bottom" .
